In this article, I’ll walk you through SentinelOne’s console, explaining how to navigate and utilize its powerful features . Think of this as part one of a series where we’ll dive deep into how SentinelOne works, what you can expect, and how it fits into forensic workflows. I’ll keep this as unbiased as possible, sharing my thoughts and experiences along the way. ------------------------------------------------------------------------------------------------------------- Getting Started with the Console When you first log in to the SentinelOne console, you’re greeted with a sleek, user-friendly interface. At the very top is the black strip , housing key navigation options and tools. Let’s break this down: Logo and Arrow :- To the left, you’ll see the logo followed by an arrow. Clicking this arrow opens up the hierarchical structure  that SentinelOne uses to organize accounts, sites, and groups . Here’s a simplified example to understand how this works: Global : If you’re an admin, this is your top level of access. Accounts : Let’s say you have a client named "ABC ." You create an account under the global level for them (each client will get single account) . Example: Global/ABC Sites : Within that account, you can create sites based on locations or departments. (You can created multiple sites) Example: Global/ABC/London or Global/ABC/US Groups : Finally, within each site , you can create groups for further segmentatio n. Example: Global/ABC/London/Finance or Global/ABC/US/Sales Hierarchy in Action : Changes applied at the account level  cascade down to all sites and groups . Changes made at the site level  only affect all groups within that site. Similarly, group-level changes don’t impact the broader site or account. ------------------------------------------------------------------------------------------------------------- Singularity Marketplace The next item on the black strip is the Singularity Marketplace . This is where SentinelOne shines in its ability to integrate logs and alerts from over 130 third-party tools —think AWS, Microsoft, GitHub, Palo Alto, Zscaler, Duo, and even tools like Recorded Future for threat enrichment . The Backstory : This feature became possible after SentinelOne acquired Scalyr  in 2021 . Scalyr was a cloud-native data analytics platform designed to handle massive log data at high speed. With this integration, SentinelOne elevated its XDR platform, allowing you to analyze and act on data from multiple sources in real-time. If you’re wondering whether you can integrate your tools into SentinelOne, the community portal has step-by-step guides for each integration . While I won’t dive into the "how-to" here, I recommend checking those out. Spoiler alert: it’s pretty straightforward. ------------------------------------------------------------------------------------------------------------- Cloud-Native Security Another noteworthy feature on the top strip is Cloud-Native Security . This tool focuses on protecting cloud resources with features like: Agentless Onboarding:  Create an inventory of assets within minutes. Verified Exploit Paths™:  Simulate attacks to identify exploitable vulnerabilities. Secrets Management:  Detect hardcoded secrets (over 800 types!). Real-Time Compliance:  Monitor cloud compliance across frameworks like PCI-DSS, SOC2, HIPAA, and more. While I won’t delve deep into this feature for now, it’s an excellent addition for teams managing hybrid infrastructures. ------------------------------------------------------------------------------------------------------------- Help and API Documentation Clicking on "Help" provides access to: Offline Help : A repository of guides and documents ( though these aren’t always up-to-date) . Customer Portal : The go-to for creating support tickets and accessing the most current documentation. API Documentation : A treasure trove for automation enthusiasts. SentinelOne’s API allows you to: Manage endpoints (e.g., quarantining devices). Perform threat analysis and hunting. Automate workflows like isolating infected endpoints or running scans. Integrate with SIEMs and IT management platforms using RESTful APIs. If you’re technically inclined, this is worth exploring. APIs are like the glue that can bind your security operations together. ------------------------------------------------------------------------------------------------------------- MITRE Framework Integration Next up is the MITRE Framework  integration. SentinelOne maps detected threats to MITRE ATT&CK TTPs (Tactics, Techniques, and Procedures). For each detection, you’ll see indicators and detailed insights, making it easier to understand the attack and respond effectively. ------------------------------------------------------------------------------------------------------------- Understanding User Details, Time Settings, and Enhanced Deep Visibility in SentinelOne User Account Overview At the far right of the black navigation strip, you’ll find your user account details . This section includes the following: Account Information :Displays your account name and the access level granted to you within SentinelOne (e.g., Administrator, Viewer). Logout Option :A simple way to log out of your SentinelOne console for security purposes. Click the option labeled "Logout" (and yes, it does what it says!). Customizing Time Settings You can configure the time settings of your SentinelOne console to suit your preferences.Options include: Local Browser Time : Matches the console’s time display to your local browser's time zone.

Dark Mode : A dimmed interface for better visibility in low-light environments, reducing strain on your eyes. Deep Visibility: From Legacy (S1QL) to Enhanced (S2QL) SentinelOne’s Deep Visibility  feature empowers you with advanced threat-hunting capabilities. Initially based on S1QL , the platform has evolved to use the enhanced S2QL  query language, which offers better efficiency and usability. S1QL (Legacy) : The older query system, which some users may still find familiar and easier to navigate. S2QL (Enhanced) : A modernized, streamlined query language for more powerful and intuitive threat hunting. You can choose which query system to use based on your comfort level and needs. Later articles I will cover both the Legacy Console with Enhanced Deep Visibility , making it easier to understand the transition to the newer system. Singularity Operations Center (SOC) At the time of this blog’s creation, SentinelOne provides an option to toggle between the Legacy Console  and the updated Singularity Operations Center . Why Choose Legacy Console First? I will starts with the Legacy Console  setup to help you understand foundational concepts. Once that’s clear, we’ll explore the updated console for advanced operations. The choice of console is yours, but this approach ensures an incremental and thorough learning experience. ------------------------------------------------------------------------------------------------------------- Left-Hand Navigation We’ve explored the top black strip.

Distributed AI: Every endpoint becomes a fortress with on-device AI capable of detecting and responding to threats, even when offline. What to Expect in This Series This series will be a journey. Here’s what I plan to cover: How to Navigate SentinelOne : A step-by-step guide to the interface , including tips and tricks for better management. Using SentinelOne for Forensics : Can you use SentinelOne as a forensic tool? Spoiler: Yes, but with some caveats. We’ll dive into that. SentinelOne vs. Other EDR Tools : I’ll share my comparisons with tools like CrowdStrike and Carbon Black, focusing on usability, detection accuracy, and overall performance. Advanced Features and Customization : From creating STAR rules to leveraging Storyline™ , we’ll explore how to maximize SentinelOne’s capabilities . XDR Capabilities : What does SentinelOne offer today, and where does it need improvement? My Honest Opinion (So Far) SentinelOne isn’t perfect—no tool is. It has its limitations, especially when compared to competitors like CrowdStrike in specific areas like XDR . However, its strengths, especially in AI-driven detection and user experience, make it a standout choice. If there’s one piece of advice I’d give to new users, it’s this: Don’t rely entirely on AI. Use custom rules to augment your defenses. Stay tuned as we embark on this detailed journey. Whether you’re an experienced user or new to the tool, I hope this series helps you understand SentinelOne better—and perhaps even fall in love with it, like I did. So you ready for this journey lets start, check out next article, Until than stay safe keep learning Akash Patel

Espionage, the art of covert information gathering, is an ancient practice that has evolved with each generation. The core drivers of espionage stem from various motives, including national interests, corporate competition, and technological advancements. Here’s a closer look at why espionage is so persistent across different domains and how it has adapted to the digital age. 1. Nation-State Espionage Nation-states engage in espionage to gain strategic advantages in military and political arenas. National intelligence agencies like the CIA (U.S.) and the former KGB (Soviet Union) serve as prime examples of state-sponsored espionage. These agencies aim to collect sensitive information about other countries to improve national security, economic strength, and influence in global negotiations. For example, knowing the negotiation strategies or weaknesses of an adversary can significantly influence outcomes, whether in trade, diplomacy, or even military strategy. Cyber-espionage has become a key component, as demonstrated by groups like Sandstorm , which have targeted critical infrastructure in adversarial nations, including the Ukrainian power grid in 2015. 2. Industrial Espionage Corporate espionage, or industrial spying, involves companies spying on one another to gain competitive advantages . Research and development ( R&D) is costly, time-intensive, and uncertain, yet essential for innovation . Some corporations, unwilling to bear these costs, opt to obtain proprietary information or trade secrets from competitors . While this is illegal in most countries, the financial gain can outweigh the legal risks , prompting corporations to factor in potential fines or penalties as a cost of doing business. High-profile cases like China’s involvement in corporate espionage against American tech firms exemplify how these operations are conducted on a global scale, often to advance a country's economic goals alongside those of specific corporations. 3. Technology and Cyber Espionage Modern espionage is tightly interwoven with technological advancements . As technology becomes more embedded in society, espionage actors have adapted, employing cutting-edge tools to exploit digital vulnerabilities . Cyber-espionage tools such as malware, social engineering, and zero-day exploits enable spies to access sensitive data remotely. Advanced Persistent Threat (APT) groups, often linked to nation-states, have increasingly used sophisticated malware to infiltrate government and corporate networks, targeting sensitive data stored on digital devices. Case Study: Turla (Uroburos/Snake) The Turla cyber-espionage campaign exemplifies the complexity of modern espionage operations. Known for its advanced malware toolkit, Turla has targeted Western government and military networks since at least 2008 . Security researchers have linked Turla to Russia, with early instances of its malware (Agent.BTZ) surfacing during an attack on the U.S. Department of Defense in 2008. Notable characteristics of the Turla group’s approach include: Innovative Persistence Techniques:  Turla utilizes techniques like COM object hijackin g to maintain l ong-term access within compromised systems. Sophisticated Command and Control (C2) Strategies :  Turla has adopted unique C2 techniques, such as using satellite-based communication to mask C2 servers , steganography to embed commands in images on social media, and custom backdoors in popular platforms like Outlook and Exchange . Social Engineering and Limited Zero-Day Use :  Turla typically relies on social engineering tactics like phishing emails and watering hole attacks for initial access rather than frequent use of zero-day exploits. Turla’s Advanced Espionage Techniques: A Closer Look Turla, an APT group believed to be linked to Russian intelligence, is known for its complex and persistent cyber-espionage campaigns. The group has carried out a range of sophisticated techniques to maintain stealth, evade detection, and establish reliable communication channels with infected devices. Here are some of their hallmark methods. 1. COM Object Hijacking for Persistence COM ( Component Object Model) hijacking is one of Turla’s primary techniques for maintaining persistence. This Windows-based tactic allows Turla to load malicious code by exploiting the COM objects that manage communication between Windows applications. By hijacking these objects, T urla can run payloads within trusted processes , such as explorer.exe or svchost.exe, making detection more challenging for security tools that often look for obvious code injection attempts. Two commonly used methods in COM hijacking include: Phantom COM Objects : Turla places references in the registry for COM objects that don’t have a corresponding file. When a process tries to access these phantom objects, the Turla malware creates the necessary files to initiate malicious behavior. COM Search Order Hijacking : Turla hijacks the search order of COM objects in the registry , prioritizing user-specific objects (under HKCU) over system-wide objects (HKLM) . This allows them to override trusted system objects with user-specific (and therefore malicious) versions. Source : Cyberbit 2. Satellite Connectivity for C2 Evasion Turla’s use of satellite connections as a command-and-control (C2) mechanism is particularly notable. By leveraging satellite internet, Turla makes it extremely difficult for law enforcement or security researchers to track the actual C2 server location . Here’s how the satellite C2 works: The infected machine connects to an IP using satellite internet. The satellite broadcasts this request across its entire coverage area, which is ignored by legitimate users. The C2 server, situated within the satellite’s coverage, intercepts the request and responds through a conventional internet connection. This setup obscures the C2 server’s true location since it can be anywhere within the satellite’s broadcast range. The wide coverage area, along with the network behavior of satellite systems, makes it nearly impossible to pinpoint the adversary’s location. Source : SecureList 3. Steganography on Social Media for C2 In a creative twist, Turla has used steganography within social media to send C2 commands . One campaign involved embedding commands within comments on Instagram posts , specifically on popular accounts like Britney Spears ’. Turla encodes URLs within these comments by using non-printable characters (such as the Zero Width Joiner, \200d ) to avoid detection. The malware scans the comments, and if a specific hash matches, it decodes the message and follows the URL for additional commands or payloads. This approach allows Turla to use public platforms for covert communication, bypassing conventional C2 detection methods by security software. The wide reach and popularity of platforms like Instagram also add a layer of anonymity, as commands can be posted from virtually any account, and the messages look like typical comments. Source : SecureList The Turla APT group, known for its sophisticated cyber-espionage tactics, expanded its toolset in 2018 and 2019 with specialized backdoors targeting Microsoft Outlook and Exchange . These campaigns reveal Turla’s focus on exploiting widely used email infrastructures to establish command and control (C2) channels, achieve persistence, and conduct covert operations. 1. Outlook Backdoor (2018) The Outlook backdoor relies on Microsoft Outlook for persistence and C2. Key features include: Command Execution and File Transfer : The backdoor supports stealth command execution and file upload/download, making it a versatile C2 channel and exfiltration method. Steganography in PDFs : Commands and data are hidden within images in PDFs, allowing Turla to transmit information undetected within normal email communication . COM Object Hijacking : Turla uses COM object hijacking to achieve persistenc e, exploiting Windows’ trusted mechanisms to remain unnoticed. T argeting Eastern Europe : The backdoor was designed to infect Outlook and "The Bat!" —a popular Eastern European email client , suggesting a geographic focus in its deployment. Source : ESET's detailed analysis 2. Exchange Backdoor (2019) The following year, Turla extended its approach to target Microsoft Exchang e servers with a backdoor that: Code Execution and Email Manipulation : Turla could execute commands, intercept, alter, and delete emails directly on the server without reaching the end-user, making it a stealthier attack method than the Outlook backdoor. Steganography in Images and PDFs : Similar to the Outlook backdoor, commands and exfiltrated data were hidden within image files embedded in PDF attachments. Installation via DLL and PowerShell : The backdoor involved installing a malicious DLL as a Transport Agent using PowerShell (Install-TransportAgent and Enable-TransportAgent cmdlets ), embedding itself deeply within the Exchange infrastructure. Custom Rule Files : Turla utilized rule files with specific conditions for each email action, such as blocking, redirecting, or altering messages, enabling them to trigger actions based on precise sender-recipient pairs. The Exchange backdoor is particularly stealthy since it operates entirely within the Exchange server environment , intercepting emails before they reach the inbox, which reduces the likelihood of detection by end-users. Source : ESET's detailed report on the LightNeuron backdoor Attribution Challenges and Resources Attribution in cyber-espionage cases like Turla’s is difficult due to technical similarities across campaigns, reuse of tactics like COM object hijacking, and cross-border IP obfuscation. Several open-source resources provide extensive details on threat actor groups: ThaiCERT’s Threat Actor Encyclopedia : A detailed resource with profiles on APT groups worldwide, continuously updated with contributions from cybersecurity researchers. Florian Roth’s APT Groups and Operations Sheet : A Google Sheet offering a high-level overview of APT groups, correlating various naming conventions used across organizations. MITRE ATT&CK Groups : This database maps known APT groups to specific techniques within the MITRE ATT&CK framework, helping security teams identify TTPs associated with different actors. For a closer look, consult resources like ThaiCERT’s Threat Actor Encyclopedia  and MITRE ATT&CK Groups . https://docs.google.com/spreadsheets/d/1H9_xaxQHpWaa4O_Son4Gx0YOIzlcBWMsdvePFX68EKU/edit?pli=1&gid=1864660085#gid=1864660085 Conclusion: The Turla campaigns underscore the sophistication and persistence required to counter modern cyber-espionage threats. By using legitimate systems like Outlook and Exchange to disguise command-and-control activities, Turla showcases the evolving landscape of stealth tactics in state-sponsored cyber operations. Their approach demonstrates the critical need for vigilance and innovation in cybersecurity, as adversaries continually adapt, reusing effective methods and targeting widely used systems to ensure their persistence and impact.

The 2016 Bangladesh Bank Heist  stands out as a significant digital theft where hackers exploited the SWIFT financial messaging system to orchestrate a massive theft from Bangladesh Bank’s account at the Federal Reserve Bank of New York. Attack Summary Intrusion Method : The attackers, possibly with insider assistance, used Dridex malware  to infiltrate the Bangladesh Bank's systems. This allowed them to monitor internal processes, especially around international transactions and payment operations. Reconnaissance and Preparation : To gather intelligence, they installed Sysmon   on systems connected to the SWIFT network, which helped them map out SWIFT’s operational patterns and employee interactions with SWIFT software. Fraudulent Transactions : Using manipulated PRT files  and Printer Command Language , the attackers initiated 35 fraudulent SWIFT messages, attempting to transfer $951 million. Thirty transactions were flagged and blocked by the New York Fed, but five transactions were processed, leading to a $101 million loss for Bangladesh Bank: $20 million  transferred to Sri Lanka  (recovered due to a typographical error). $81 million  routed to the Philippines , where $18 million was later recovered. Final Losses : After partial recovery, B angladesh Bank faced a $63 million loss . Much of this was swiftly laundered through casinos in the Philippines. Understanding SWIFT's Role in International Transactions The SWIFT network facilitates secure financial messaging between banks globally. To grasp the heist's complexity, understanding the VOSTRO/NOSTRO  account setup is essential. Here's a simplified example to illustrate how SWIFT functions in an international transfer scenario: Initiation : The buyer's bank (Bangladesh Bank) receives a request to transfer a large amount, e.g., $10 million. Intermediary Use : Due to high international transfer amounts and limited access to foreign markets, the transaction involves an intermediary bank. NOSTRO  and VOSTRO  are accounting terms used in this setup, where Bangladesh Bank maintains a VOSTRO account with the NY Fed. Transaction Flow : Bangladesh Bank instructs the NY Fed to debit its VOSTRO account and transfer the amount to the seller’s bank. Transaction Completion : The NY Fed deducts the amount from the VOSTRO account and completes the transfer to the recipient bank. Bangladesh Bank’s SWIFT Technical Architecture The bank’s SWIFT setup involved four main components, interconnected via a VPN: Core Bank IT Systems : Handle regular banking transactions. SWIFT Messaging Bridge : Generates SWIFT messages for transactions. SWIFT Gateway : Ensures secure connectivity between banks via SWIFT protocols. Confirmation Printer : Provides a physical record of transaction confirmations for verification. Attack Execution on SWIFT Systems Malware Deployment : Attackers installed malware on servers running SWIFT Alliance software , responsible for SWIFT message handling and validation. DLL Manipulation : The malware checked active Windows processes for liboradb.dll , a crucial SWIFT component, and patched it in memory to bypass transaction validations by altering the code (JNZ instruction). Message Injection : With the patched DLL, attackers could inject unauthorized SWIFT messages into the network without triggering file integrity or signature checks, making the fake transactions appear legitimate. The Bangladesh Bank Heist: The Intrusion During the attack, the adversaries compromised systems running the SWIFT messaging bridge software, allowing them to inject fraudulent SWIFT messages. Notably, the bank’s internal IT systems were unaware of this intrusion, as the fraudulent transactions were directly injected into the SWIFT network. The Bangladesh Bank Heist: Zooming in on the Malware The malware specifically targeted the Bangladesh Bank’s servers running the SWIFT Alliance software, which manages SWIFT message transactions. The software performs complex validation checks, which the malware altered to bypass these checks. When executed on the server, the malware scanned all running processes and modules on the Windows OS, searching for the liboradb.dll file . This DLL, a part of the SWIFT Alliance software, handles: Reading the Alliance database path from the registry Starting the database Performing backup and restore functions for the database In processes loading liboradb.dll, the malware altered the DLL in memory by replacing a specific JNZ instruction with two NOP instructions. This bypass caused SWIFT’s validation checks to always succeed, allowing counterfeit transactions to be approved. The in-memory patching allowed the attackers to avoid detection from integrity checks or digital signature validations on SWIFT’s software files. With this modification, counterfeit SWIFT messages could be injected directly into the database. The Bangladesh Bank Heist: Zooming in on the Malware Original Code Manipulated Dll To ensure this function always returns success, the jnz instruction was removed. Instead of deleting the bytes, the malware authors replaced them with NOP (No Operation) instructions, preserving code structure and bypassing the jump condition. This technique is common in machine code patching. The Bangladesh Bank Heist: The Intrusion The malware also intercepted SWIFT gateway confirmations, preventing them from being printed. However, when the confirmation printer malfunctioned , it failed to print any transactions, which raised suspicion . Once it was operational, the backlog—including the injected transactions—was printed. Despite this misstep, the attackers managed to process some transactions successfully due to careful planning. The Bangladesh Bank Heist: The Fraud Flow The attackers initially injected 35 transactions totaling $951M. Of these, 30 transactions were blocked due to the keyword “Jupiter” in the bank address, flagged by the NY Fed due to an unrelated sanction hit. Five transactions, totaling $101M, were processed by the NY Fed. Four of these succeeded and were directed to three pre-established accounts at the Rizal Commercial Banking Corporation (RCBC) in the Philippines. One transaction was blocked due to a typo ("Shalika foundation" vs. "Shalika fandation"), prompting Deutsche Bank to request verification from Bangladesh Bank. The successful $81M transferred to RCBC was further funneled to casino accounts, where it was withdrawn and laundered. The Bangladesh Bank Heist: Key Takeaways The Bangladesh Bank heist serves as a critical example of vulnerabilities in financial institutions and the sophisticated tactics employed by attackers. Here are some essential insights from the incident: Cybersecurity Posture : The Bangladesh Bank’s cybersecurity framework was alarmingly inadequate, particularly for a financial institution. Lacking network segmentation and relying on low-cost, secondhand infrastructure made it easier for attackers to infiltrate. SWIFT Vulnerabilities : Although SWIFT is known for its secure environment, this heist revealed that its s ecurity is only as strong as its weakest link. The attack exploited the bank’s infrastructure without directly targeting SWIFT itself. This incident motivated SWIFT to launch its Customer Security Program (CSP) to enhance the security of institutions within its network. Meticulous Planning : The heist was strategically timed, taking advantage of bank holidays and off-hours when responses would be delayed . This planning allowed the attackers to avoid immediate detection. Extended Network Access : Attackers had been lurking within Bangladesh Bank’s network for a significant period before executing their plan. This prolonged access likely hindered the ability to identify the initial breach point, highlighting the need for improved network monitoring that could have detected the intrusion sooner. Cyber Crime: Notable Ransomware Families The evolution of ransomware has resulted in the emergence of numerous families, each with unique tactics and impact. Here are some significant ransomware variants: Locky : Highly versatile, Locky can spread through exploit kits or traditional phishing emails, making it widely adaptable and popular. Cerber : Known for its multifaceted approach, Cerber not only encrypts files but can also launch DDoS attacks against its victims. Jigsaw : Inspired by the "Saw" movie series, Jigsaw both encrypts and exfiltrates data, increasing pressure on victims to pay the ransom. Crysis & LeChiffre : Both leverage brute-force attacks against RDP to infiltrate systems, avoiding traditional phishing methods. Goldeneye, Petya, & HDDCryptor : These ransomware variants don’t just encrypt files; when run with admin rights, they encrypt entire hard drives, even overwriting the Master Boot Record. Popcorn Time : This variant introduces a “social” twist, offering victims the decryption key for free if they successfully infect others. WannaCry (Wcry) : Famous for its May 2017 attack, WannaCry exploited an SMB vulnerability (leaked by ShadowBrokers) to spread across networks, impacting several large organizations. NotPetya : Rising to prominence in June 2017, NotPetya combined SMB exploits with credential-stealing tools like Mimikatz, followed by lateral movement techniques like PsExec/WMIC. Many believe its true aim was widespread disruption rather than ransom collection. GandCrab : Launched in January 2018, GandCrab popularized the Ransomware-as-a-Service (RaaS) model, enabling less skilled cybercriminals to deploy ransomware. Its creators announced the end of operations on May 31, 2019. Ryuk : Primarily targeting large organizations, Ryuk ransomware operators aim to control entire networks and coordinate a wide distribution of the malware, hoping for substantial ransom payouts. Maze : Known for data theft, Maze often enters systems via phishing and post-compromise utility execution. Before encryption, it exfiltrates data, threatening public exposure if the victim refuses to pay.

The Bangladesh Bank incident highlighted how vulnerabilities in basic cybersecurity practices—such as poor network segmentation, outdated infrastructure, and lack of proactive monitoring—can expose even the most secure systems, like SWIFT, to indirect threats. This event spurred initiatives like the SWIFT Customer Security Program (CSP), underscoring that security must be holistic, addressing even the weakest links. Akash Patel

BlackEnergy: Lights Out in Ukraine On December 23, 2015, a sophisticated cyber attack plunged 200,000 Ukrainians into darkness, cutting off their power for up to six hours. The attackers targeted three power distribution companies, marking the first-ever known cyber attack to disrupt a nation’s power grid. The malware used in this attack, known as BlackEnergy , is believed to have been deployed by the Russian Advanced Persistent Threat (APT) group, Sandworm , likely as part of the ongoing Russia-Ukraine conflict that began in 2014. This event underscored the potential of cyber attacks to cause physical damage and disrupt critical infrastructure. How BlackEnergy Operated The attack began with spear-phishing emails sent to key staff within the Ukrainian power companies. These emails contained malicious Microsoft Office documents that, when opened, executed BlackEnergy  malware on the victims’ systems. BlackEnergy is a modular malware platform not specifically designed for SCADA (Supervisory Control and Data Acquisition) systems, but it proved adaptable enough to compromise Windows workstations connected to SCADA . The attackers used these compromised workstations to gain control over substations and open circuit breakers, cutting electricity to 200,000 people. To prolong the outage, the attackers deployed additional tactics, including wiping the infected machines with KillDisk , making it impossible for operators to restore power remotely. Utility company staff were forced to manually visit substations to restore power—a process that took hours. To further frustrate recovery efforts, the attackers launched a denial-of-service (DoS)  attack on the companies’ customer service lines, preventing customers from reporting outages and blocking crucial communication channels for the power companies . This unprecedented cyber attack underscored vulnerabilities in industrial control systems and exposed the real-world impact of cyber warfare on civilian infrastructure. NotPetya: The Devastating Supply Chain Attack Another significant cyber attack targeting Ukraine, NotPetya , occurred in June 2017 . Though initially disguised as ransomware, NotPetya’s true aim was not financial gain but widespread destruction. It quickly spread beyond Ukraine’s borders, impacting organizations worldwide and causing billions in damages, including losses for companies like Maersk and FedEx. NotPetya’s Mechanism and Impact The NotPetya  malware was introduced through a supply chain compromise. Attackers initially infiltrated the network of Linkos Group , a Ukrainian software developer, and i nserted NotPetya into updates of Medoc , a widely-used tax software in Ukraine. When Medoc clients downloaded the compromised updates, NotPetya was deployed across multiple systems, establishing a "patient zero" in numerous corporate networks. Once activated, NotPetya used a blend of strategies to spread and maximize damage: Initial Infection : NotPetya encrypted files and overwrote the Master Boot Record (MBR), rendering infected systems inoperable. Credential Dumping : The malware used tools like Mimikatz  to extract login credentials from the Local Security Authority Subsystem Service (LSASS) memory, allowing it to reuse credentials to spread within the corporate network. Propagation : For unpatched systems, NotPetya exploited the EternalBlue  and EternalRomance  vulnerabilities , which affected Windows systems and allowed it to spread through network ports 139 and 445 . For patched systems, it leveraged the stolen credentials to spread laterally using PSExec  and WMIC  commands , infecting even those with up-to-date security patches. Why BlackEnergy and NotPetya Were So Significant Both BlackEnergy and NotPetya serve as critical examples of how cyber warfare has evolved to target national infrastructure and private sector supply chains. BlackEnergy was a pioneering attack that took down physical system s through cyber methods, while NotPetya illustrated how a supply chain attack could deliver a destructive payload globally. Together, they highlight the vulnerabilities within critical infrastructure and supply chains, which attackers can exploit to achieve wide-reaching impacts beyond national borders. Lessons Learned and Ongoing Risks Industrial Control System (ICS) Security : The BlackEnergy  attack underscored the risks in ICS environments that are increasingly network-connected yet lack cybersecurity defenses. Supply Chain Vulnerabilities : NotPetya exposed the risks inherent in software supply chains, showing that a compromised update could devastate a wide range of industries and even spread internationally. Preparedness and Response : These attacks emphasized the need for companies to maintain strong cyber defenses, including robust backup and recovery strategies, continuous security updates, and comprehensive incident response plans. Conclusion: In a world where digital and physical infrastructures are deeply interconnected, the lessons from BlackEnergy and NotPetya continue to resonate, reminding us of the critical importance of vigilance, resilience, and innovation in the face of evolving cyber threats.

In cloud-based environments like Azure, maintaining comprehensive visibility over all activities is essential for securing your infrastructure and responding effectively to incidents. One of the most critical tools in your security arsenal is logging . Azure provides a variety of log sources, but not all are enabled by default. Understanding where these logs come from, how to access them, and how to store them can significantly improve your ability to investigate incidents and mitigate risks. The Five Key Azure Log Sources Azure collects logs from various levels of the cloud infrastructure, each serving a unique role in monitoring and security. Here are the five primary log sources you need to be aware of: Tenant Logs Subscription Logs Resource Logs Operating System Logs Application Logs Let’s explore each of these in more detail. Tenant Turned on by default Used to detect password spray attacks or other credentian abuses. Subscription Turned on by default Used to analyze the creation, deletion, start/stop of resources in cases such as crypto mining VM incidents or mass deletion for sabotage cases. Resource Turned off by default Used to log network traffic flow, file storage access for cases such as data exfiltration. Operating System Turned off by default Used to log operating system events, which can show lateral movement. Application Turned off by default Used to create custom logs at the discretion of developers. Azure includes a log for IIS that can be used to show web servers attacks. ------------------------------------------------------------------------------------------------------------- Why Proper Logging Matters in Incident Response In many cases, when an organization is called to respond to a security incident, the first challenge is discovering that key logs were never configured or stored . This leaves responders with limited information and hampers their ability to fully understand the attack. Why is this important? Comprehensive Monitoring : Many log sources, such as resource and OS logs, must be enabled manually . Without these logs, crucial events like unauthorized access or file manipulation might go unnoticed. Cost of Storage : Logs must be stored in Azure, often in a Log Analytics Workspace  or similar storage solution, which incurs additional costs. Without proper budgeting and planning, organizations might avoid enabling these logs due to perceived costs, leaving them vulnerable. Log Retention : Depending on your configuration, logs might only be stored for a short period before being overwritten. Having a strategy in place for exporting and storing logs in a secure, centralized location (such as a SIEM  system) is essential. The ideal setup is to continuously export these logs to a SIEM , where they can be stored long-term and analyzed even after an incident has occurred. This prevents attackers from covering their tracks by deleting logs stored locally in Azure. ------------------------------------------------------------------------------------------------------------- Log Analytics Workspace: Centralizing Your Logs for Efficient Analysis Azure provides a Log Analytics Workspace  as a centralized repository where logs from multiple sources, both Azure-based and non-Azure, can be aggregated and analyzed. This workspace organizes logs into tables , with each data source creating its own table. Key benefits of using a Log Analytics Workspace include: Scalability : The default workspace can handle up to 6GB of logs per minute  and s tore up to 4TB of data per day . This is generally sufficient for most organizations, though custom workspaces can be created for larger log volumes. Access Control : You can set granular permissions based on security roles, ensuring that sensitive logs are only accessible to authorized personnel. By setting up a Log Analytics Workspace, you can automate the collection of logs from all relevant sources and integrate with Azure Monitor  for real-time alerting and analysis. https://learn.microsoft.com/en-us/azure/azure-monitor/logs/workspace-design https://learn.microsoft.com/en-us/azure/azure-monitor/logs/manage-access?tabs=portal ------------------------------------------------------------------------------------------------------------- Setting Up Log Analytics Workspace in Azure A Log Analytics Workspace  allows you to aggregate logs from multiple Azure services and third-party tools into one place. Here’s how to set it up: Step-by-Step Guide to Creating a Log Analytics Workspace Step 1: Sign in to the Azure Portal Go to Azure Portal  and sign in with your credentials. Step 2: Search for 'Log Analytics Workspaces' In the search bar at the top, type Log Analytics Workspaces  and select the service from the list. Step 3: Create a New Workspace Click New  to create a new workspace. Enter the required details: Subscription : Select your Azure subscription. Resource Group : Choose an existing resource group or create a new one. Workspace Name : Name your workspace (e.g., "SecurityLogsWorkspace"). Region : Choose the region where you want the workspace to reside. Step 4: Review and Create After entering all details, click Review + Create  and then Create  to deploy your Log Analytics Workspace. This workspace will serve as a centralized location for all logs, which can be expanded to include tenant logs, subscription logs, resource logs, and more. For more details on creating a Log Analytics workspace, visit Microsoft’s official documentation. https://learn.microsoft.com/en-us/azure/azure-monitor/logs/quick-create-workspace?tabs=azure-portal https://learn.microsoft.com/en-us/azure/azure-monitor/logs/quick-create-workspace?tabs=azure-portal ------------------------------------------------------------------------------------------------------------- Tenant Logs: Overview and Access Tenant logs provide information about operations conducted by tenant-wide services  like Azure Active Directory (AAD)( Entra ID) . These logs are essential for monitoring security-related events such as sign-ins, user provisioning, and audit trails. The key AAD logs include: Audit Logs : Track changes and configuration updates across the tenant. Sign-in Logs : Provide detailed records of user login activity, including success, failure, and multi-factor authentication (MFA) usage. Viewing Tenant Logs in the Azure Portal Sign-in Logs To quickly check sign-in activity, go to the Azure Portal  and navigate t o Azure Active Directory(Entra ID)  > Sign-ins . Here you can view sign-in logs for the last 30 days , showing details such as user, date, status (success, failure, interrupted), and the IP address used. https://learn.microsoft.com/en-us/entra/fundamentals/how-to-manage-user-profile-info Audit Logs Similarly, go to Azure Active Directory(Entra ID)  > Audit Logs  to see tenant-wide changes, such as user account updates and administrative configuration changes. However, the Azure portal  limits logs to the last 30 days , making it unsuitable for long-term forensic analysis or detailed investigations. For comprehensive analysis and historical data retention, s toring logs in a Log Analytics Workspace  is a much better approach. ------------------------------------------------------------------------------------------------------------- Exporting Azure Active Directory Logs to Log Analytics Workspace (Now AAD name have been modified to Entra ID) To take full advantage of tenant logs , including AAD audit and sign-in logs, you should configure the logs to be stored in your Log Analytics Workspace . This allows for extended retention periods, deeper analysis, and cross-correlation with other logs. Step-by-Step Guide to Exporting AAD Logs(Entra ID logs) Step 1: Navigate to Azure Active Directory(Entra ID logs) In the Azure Portal, search for and select Azure Active Directory  from the services list. Step 2: Configure Diagnostic Settings From the AAD  menu, select Diagnostic settings . Click Add diagnostic setting  to configure where the logs will be stored. ------------------------------------------------------------------------------------------------------------- Selecting AAD Logs(Entra ID) and Setting Up Log Analytics Workspace After setting up your Log Analytics Workspace  (as described in previous steps) , the next task is to configure which AAD logs  you want to capture and send to the workspace . Azure provides several types of logs that you can export for analysis: Audit Logs : Logs changes such as adding or removing users, groups, roles, policies, and applications. Sign-in Logs : Tracks sign-in activities, including: User sign-in : Captures direct user login events. Non-interactive sign-in : Logs background sign-ins, such as token refreshes. Service Principal sign-in : Logs sign-ins performed by service principals (used by applications). Managed Identity sign-in : Captures sign-ins for managed identities. Provisioning Logs : Tracks user, group, and role provisioning activities performed by Azure AD. ADFS Sign-in Logs : Monitors federation sign-in events through Active Directory Federation Services (ADFS) . Identity Protection Logs : Tracks risky users and events, including RiskyUsers , UserRiskEvents , RiskyServicePrincipals , and ServicePrincipalRiskEvents . N etwork Access Traffic Logs : Logs network traffic for policy and risk management, including user experience data. To set this up : Navigate to Diagnostic Settings : Go to the Azure Active Directory  ( Entra ID ) service in the Azure portal. In the left menu, click Diagnostic settings  and then select Add diagnostic setting . Choose Logs to Export : Select the categories of logs you want to export to the Log Analytics Workspace  (e.g., AuditLogs, SignInLogs, ProvisioningLogs). Specify the Log Analytics Workspace  where these logs will be stored. Save Settings : Confirm the logs you’ve selected and save the diagnostic setting. Once configured, these logs will be automatically sent to the designated Log Analytics Workspace  for long-term storage and analysis. https://learn.microsoft.com/en-us/entra/id-protection/ ------------------------------------------------------------------------------------------------------------- Managing Storage Costs While it may be tempting to store all available logs, storage costs can accumulate quickly, especially for large organizations with a lot of activity. One cost-saving measure is to use Azure Storage Accounts  for logs that don't require constant querying but need to be archived for compliance or later use. For critical logs, such as sign-in  and audit logs , continuous export to the Log Analytics Workspace  is recommended for monitoring real-time activity and performing incident response. However, less frequently accessed logs can be stored more cost-effectively in a storage account. ------------------------------------------------------------------------------------------------------------- Querying AAD Logs(Entra ID logs) Using Kusto Query Language (KQL) Once AAD logs are flowing into your Log Analytics Workspace, you can use Kusto Query Language (KQL)  to search, filter, and analyze log data. KQL is a powerful language for querying logs and has a syntax similar to SQL, making it approachable for those familiar with databases. Example of a Simple KQL Query: SigninLogs | where TimeGenerated > ago(1d) | where ResultType == 0 SigninLogs : The first line specifies the log type you want to search. TimeGenerated > ago(1d) : Filters the query to only include logs from the past 24 hours. ResultType == 0 : This line filters for successful logins (ResultType 0 corresponds to success). This simple query helps you identify all successful sign-in attempts in the last 24 hours. KQL also allows for more complex queries involving joins, aggregations, and visualizations, making it a robust tool for analyzing log data. For more details on KQL, visit Microsoft’s KQL Documentation . ------------------------------------------------------------------------------------------------------------- Using Pre-Built Queries in Log Analytics Microsoft also provides a set of pre-built queries  for common scenarios , such as analyzing sign-ins, audit events, or identifying risky behavior in your tenant. These queries serve as templates, which you can customize based on your specific investigation needs. Pre-Built Queries : These are particularly useful when first starting with KQL, as they provide a foundation for your own queries and ensure you're asking the right questions of your data. To use these pre-built queries: Open your Log Analytics Workspace  in the Azure portal. Navigate to the Logs  section. Search for the desired query in the query library, or start with a template and adjust it to suit your needs. https://learn.microsoft.com/en-us/azure/azure-monitor/logs/log-analytics-overview ------------------------------------------------------------------------------------------------------------- Further we will talk in next blog, Until than stay safe and keep learning Akash Patel ---------------------------------------------------------------------------------------------------------- Special Thanks (Iqra) I would like to extend my heartfelt gratitude to one of my dearest colleagues, a Microsoft Certified Trainer, for her invaluable assistance in creating these articles.

Microsoft Azure is a vast ecosystem of cloud-based services and tools, offering almost limitless possibilities for building, managing, and scaling applications. But when it comes to incident response or forensic investigation, the Azure landscape can feel overwhelming . To make things clearer, let's focus on the essential elements you're most likely to encounter during such operations. Understanding Azure's Structure: The Building Blocks Think of Azure as a layered architectur e, with each layer adding a distinct function that contributes to how an organization manages and controls its cloud resources . Here are the key components: 1. **Azure Tenant** Picture the tenant as the foundation of a house —the basis for everything else. It represents the entire organization and is associated with an **Azure Active Directory (AAD)(Entra ID)** instance, which handles identity and access management . If you're responding to a security breach, this is where you'll likely start your investigation—analyzing user and group permissions in AAD to find any clues about unauthorized access . 2. **Management Groups** In larger enterprises, it's common to have many different projects running across Azure, each with its own budget, team, and purpose. To keep things tidy, **management groups** help organize multiple subscriptions under a single umbrella. For example, a company could have different management groups for its production and development environments. This setup lets administrators apply policies across all relevant subscriptions in one go—a time-saving feature that also helps standardize security practices. **For Example**: Imagine you're investigating a security incident in a multinational corporation. You may find that production environments are more tightly controlled compared to development, thanks to separate management groups. This organization helps you narrow down where a misconfiguration or security hole might exist. 3. **Subscriptions** Subscriptions are like folders within the cloud that help organize resources and manage billing. Each subscription can contain a collection of resources such as virtual machines, storage accounts, and databases. In a forensic investigation, this is where things get interesting because every subscription can have different access permissions. **Key Point**: If you're investigating a security breach, ensure you have access to all relevant subscriptions because the compromised resource could be hidden within a subscription you're not initially granted access to. 4. **Resource Groups** Moving deeper into Azure's structure, r esource groups act as containers that hold related resources, such as virtual machines or storage accounts. For example, a company might group all resources related to a specific app in one resource group. **Investigative Tip**: Sometimes, you’ll only get access to a single resource group rather than an entire subscription. In that case, your view of the infrastructure will be narrow, limiting your ability to see the bigger picture. Whenever possible, push for subscription-level access. 5. **Resources** Finally, resources are the individual services and assets—virtual machines, networking components, storage accounts, and so on . They are the nuts and bolts of Azure, and they are also the focus of most investigations. For example, if a virtual machine has been compromised, you'll need to scrutinize the VM, its associated storage, and network configurations to understand the breach. ------------------------------------------------------------------------------------------------------------- ### Subscriptions: The Power Behind Azure's Flexibility Once your tenant is up and running, you’ll need to define one or more **subscriptions**. Each subscription is essentially a contract with Microsoft for cloud services, with charges accumulating based on usage . Large companies often set up multiple subscriptions to track different projects, which also helps them monitor costs across various departments or teams. During an investigation, gaining access to the right subscription is crucial because that's where the resources live. Permissions at this level can make or break your ability to fully explore and analyze cloud infrastructure. It’s also worth noting that subscriptions come with limits—for example, the number of virtual CPUs (vCPUs) might be capped. If a breach involves a resource-heavy virtual machine, you may need to request a limit increase from Microsoft. https://learn.microsoft.com/en-us/microsoft-365/enterprise/subscriptions-licenses-accounts-and-tenants-for-microsoft-cloud-offerings?view=o365-worldwide ------------------------------------------------------------------------------------------------------------- ### Azure Resource Manager: The Conductor of the Cloud Before diving into specifics like virtual networks or storage, it's essential to understand **Azure Resource Manager (ARM)**. T hink of ARM as the brain behind all deployments in Azure. It provides a management layer, handling the creation, updating, and deletion of resources. One of ARM's strengths is that it takes input from various interfaces—Azure Portal, PowerShell, CLI, or even REST APIs—and ensures consistency across them. It’s especially useful during a forensic investigation because you can use any of these tools to explore resource configurations or query logs. ARM also supports templates, written in JSON, that allow resources to be deployed consistently . These templates serve as a record of how resources were deployed and configured, offering valuable information during an investigation. For example, if a misconfigured virtual machine was deployed using an ARM template, you could identify that exact misconfiguration and track how it might have contributed to a breach. https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/overview ------------------------------------------------------------------------------------------------------------- Why Resource Groups Matter for Incident Response From an incident response  and forensic investigation  perspective, understanding resource groups is essential. Often, the resources involved in an attack or breach will be grouped together under a specific resource group, allowing you to track and manage them collectively. For example: Ease of Management : If an attacker compromises several virtual machines within a resource group, you can manage, update, or even delete all the compromised resources in one go by targeting the resource group. Access Control : Role-based access control (RBAC) can be set at the resource group level. This means that permissions for an entire group of resources can be managed centrally, making it easier to ensure that only authorized users have access. However, o ne potential challenge is that during investigations, you might only be granted access to a specific resource group rather than the entire subscription. While this can be helpful for isolating resources, it limits your view of the full Azure environment. If you're only granted permissions for one resource group , you could miss key elements or additional compromised resources in other parts of the subscription. Always aim to request higher-level permissions for a complete view during an investigation. ------------------------------------------------------------------------------------------------------------- Azure Resource Providers: The Backend Support Each resource in Azure is managed by a resource provider , which is a service responsible for provisioning, managing, and configuring the resources. For example: To deploy a virtual machine , Azure uses the Microsoft.Compute resource provider . For a storage account , the Microsoft.Storage resource provider is used . When performing investigations or responding to incidents, you won't directly interact with resource providers most of the time. However, understanding that they operate in the background helps you track what services are involved when examining Azure Resource Manager (ARM) templates or logs. ------------------------------------------------------------------------------------------------------------- Key Azure Services for Incident Response and Forensics For forensic investigations and incident response, there are certain Azure products you’re likely to interact with the most: Identity and Access Management : Azure Active Directory (AAD)/Entra ID : Controls identity and access management, a key area to investigate when tracking how a threat actor gained access to a compromised account or service. Networking : Virtual Networks (VNet) : Helps isolate resources and control network traffic. Network Security Groups (NSGs) : Filters network traffic, which can help track network traffic anomalies during an incident. Compute : Virtual Machines (VMs) : Key investigation targets in cases of compromised systems. Both Linux and Windows VMs are supported. Azure Functions : Provides compute-on-demand and could be abused by attackers for running scripts in a serverless environment. Storage : Disk Storage : Persistent storage for VMs. Investigators might need to examine disk snapshots or backups to analyze compromised systems. Blob Storage : REST-based object storage for storing unstructured data, which can be a target for data exfiltration. Storage Explorer : A graphical tool for viewing and interacting with Azure storage resources, useful for accessing storage data during investigations. Analytics : Log Analytics : Allows you to collect and search through logs, essential for tracking suspicious activity across resources. Azure Sentinel : A cloud-native SIEM (Security Information and Event Management) platform, which aggregates data from across the environment and uses intelligent analytics to identify and respond to potential threats. https://azure.microsoft.com/en-us/products/ ------------------------------------------------------------------------------------------------------------- Resource Identification in Azure: Understanding Resource IDs Azure resources are uniquely identified using a Universal Resource Identifier (URI) . This format helps trace individual resources and track their relationships within the Azure environment, which is critical during incident response. A typical resource URI follows this structure: /subscription//resourceGroups//providers/// SubscriptionId : The globally unique identifier for the subscription. resourceGroups : The user-generated name of the resource group. providerName : The resource provider responsible for managing that resource (e.g., Microsoft.Compute for VMs). resourceType : The type of resource (e.g., virtualMachines). resourceName : The specific name of the resource. For example, in the case of a virtual machine named "MiningVM": The resource ID might include URIs for the VM itself, the operating system (OS) disk, the network interface, and even a public IP address (if assigned). Investigators can use these URIs to track and manage each component of a compromised resoure ------------------------------------------------------------------------------------------------------------- ### Investigating Identity and Access: Role-Based Access Control (RBAC) Azure’s **Role-Based Access Control (RBAC)** is like a security guard at the gates of every resource . It defines who has access to what and what they can do with it —read, write, or delete. During an investigation, understanding RBAC is critical because you’ll need to know who had access to a compromised resource and whether their access was appropriate. For instance, each resource in Azure has a **scope**, which could be at the level of a management group, subscription, or resource group. A role assignment defines who (user or service account) can do what (role definition) within that scope. The most common roles are **Owner**, **Contributor**, and **Reader**, but custom roles can be created as well. Imagine you’re looking into an incident where sensitive data was leaked from a storage account. By examining RBAC, you might discover that a developer had unnecessary write access to the account, or that a third-party contractor was given too much control over key resources. https://learn.microsoft.com/en-us/azure/role-based-access-control/built-in-roles https://learn.microsoft.com/en-us/azure/role-based-access-control/overview ------------------------------------------------------------------------------------------------------------- ### Real-World Example: Tracing an Azure Security Breach Let’s put it all together with a simple example. Suppose a virtual machine (VM) in your Azure environment was hacked. You start your investigation by looking into the **subscription** where the VM resides. First, you check **Azure Resource Manager** to view the deployment history of the VM. By examining the **ARM template**, you see that the VM was configured with an outdated operating system, which may have been the entry point for the attacker. Next, you use **RBAC** to review who had access to the resource group containing the VM. You discover that a former employee still had **Owner** access, which allowed them to modify settings and potentially introduce vulnerabilities. Finally, you dive into **Log Analytics** to trace the attacker’s movements through the VM’s logs, giving you a clear picture of how the breach occurred. ------------------------------------------------------------------------------------------------------------- When it comes to managing user access in Microsoft Azure, especially during investigations, things can get complicated quickly. Azure uses Role-Based Access Control (RBAC) , which defines who has access to what resources and what they can do with those resources. The challenge comes when a user’s permissions are scattered across multiple subscriptions and resource groups. Administrators often need to enumerate role assignments  to fully understand a user’s level of access. Here’s how that can be achieved using Azure's tools. Listing User Role Assignments: Azure CLI and PowerShell The Azure CLI  and PowerShell  provide the most efficient ways to list user role assignments across different levels of Azure resources. Using Azure CLI to List Role Assignments The Azure CLI  allows you to enumerate role assignments by issuing a command to list all the roles a user has across resources. The steps are: Select the appropriate subscription : First, make sure you’ve selected the subscription that holds the resources you're investigating: az account set --subscription "subscription_name_or_id" List role assignments : Use the az role assignment list command to list all role assignments for a specific user within that subscription . The key parameters here are --all to search recursively and --assignee to specify the user. az role assignment list --all --assignee "user_email_or_id" This will list the user’s roles at both the subscription and resource group levels. If they have owner-level access to a specific resource group but no broader subscription access, this command will reveal that. Using PowerShell to List Role Assignments Similarly, you can achieve the same results using PowerShell  with the Get-AzRoleAssignment command. Install and set up Azure PowerShell :If you haven't already, install the Azure PowerShell module Install-Module -Name Az -AllowClobber Authenticate and select the subscription : Authenticate with your Azure account and choose the correct subscription. Connect-AzAccount Select-AzSubscription -SubscriptionId "subscription_id" List role assignments for the user : Use the following command to list role assignments: Get-AzRoleAssignment -ObjectId (Get-AzADUser -UserPrincipalName "user_email").Id This will return all roles assigned to the user, including those at the subscription or resource group level. Why This Matters for Investigations In cases where a security incident or breach is being investigated, it’s critical to understand who had access to what . For example, a user might not have direct access to a subscription but could hold Owner  permissions at a specific resource group or even an individual resource level, which could lead to security loopholes. If the user has elevated permissions—such as Owner  or Contributor —on critical resources, this could be an entry point for an attacker to escalate their control over the environment. Listing all role assignments helps pinpoint misconfigurations or excessive access that might have been leveraged during an attack. ------------------------------------------------------------------------------------------------------------- MITRE ATT&CK® and Azure: Understanding Threat Actor Behavior The MITRE ATT&CK® framework  provides an extensive matrix of tactics and techniques that threat actors commonly use when attacking cloud platforms like Azure. For instance, attackers frequently aim to: Obtain and verify credentials : Attackers often exploit legacy protocols like IMAP, which lack strong security measures. Enforcing multi-factor authentication (MFA)  and disabling legacy protocols are essential to mitigate these risks. Exfiltrate data via storage accounts : Attackers might abuse Azure’s Blob Storage  or use the Microsoft Graph API  to access and extract sensitive information. The MITRE ATT&CK framework has detailed mappings for Office 365 , Azure AD , and other Azure services, which makes it easier to correlate specific threat tactics with your security controls. Microsoft has even mapped its built-in Azure security controls against MITRE ATT&CK to create a library of 48 potential defenses. You can explore Azure security mappings here: MITRE ATT&CK for Cloud Azure Security Controls Mapped to MITRE ------------------------------------------------------------------------------------------------------------- Accessing Azure: CLI, Portal, PowerShell, and Graph API There are four primary ways to interact with Azure during your investigation or daily operations: Azure Portal : The graphical interface for viewing and managing Azure resources. Azure CLI : A command-line interface for automating resource management. PowerShell : Ideal for Windows users who prefer scripting in PowerShell to manage Azure. Microsoft Graph API : A RESTful API that allows programmatic access to Azure services, providing deep integration into apps and custom tools. The Azure CLI  and PowerShell  options are especially important for large-scale environments where running commands on the fly is necessary to quickly retrieve information. Cloud Shell —a terminal within the Azure Portal—also provides access to these tools without needing local installations. https://learn.microsoft.com/en-us/cli/azure/what-is-azure-cli https://learn.microsoft.com/en-us/cli/azure/install-azure-cli https://learn.microsoft.com/en-us/azure/cloud-shell/overview https://learn.microsoft.com/en-us/azure/cloud-shell/get-started/classic?tabs=azurecli Investigating Cloud Shell: Bash vs PowerShell Artifacts An interesting point to consider during an investigation is whether the attacker used Cloud Shell  for their activities. When a user initiates a Cloud Shell session, a storage account is automatically created to store the environment. If Bash  was used, traditional Linux forensics  can be applied, such as analyzing the .bash_history file to see the commands issued by the user. However, there’s a limitation: PowerShell Cloud Shell  leaves fewer artifacts. While the underlying actions will still be logged (e.g., through Azure Audit Logs ), direct forensics from PowerShell Cloud Shell is limited. https://learn.microsoft.com/en-us/azure/cloud-shell/get-started/classic?tabs=azurecli Conclusion Effectively managing and investigating user access in Azure requires understanding the nuances of role assignments across different subscriptions and resources. Tools like Azure CLI  and PowerShell  make it easier to enumerate these roles, while frameworks like MITRE ATT&CK®  provide insight into threat actor behavior in cloud environments. The right combination of access control, security controls, and investigative tools can significantly enhance your incident response capabilities in Azure.

When conducting incident response in the cloud, there often comes a point when logs alone aren’t enough, and we need direct access to data from the affected machine . A cquiring an image of a virtual machine (VM) in Azure and analyzing it in the cloud can save both time and egress costs compared to downloading it . This guide will walk you through each step in setting up and performing forensic analysis in the cloud, using a dedicated “Forensic VM” to examine a disk image created from a “Victim VM.” https://learn.microsoft.com/en-us/azure/import-export/storage-import-export-service Steps to Perform In-Cloud Forensic Analysis: Step 1: Snapshot the OS Disk from the Victim VM To start, take a snapshot of the VM’s disk. A snapshot is a full, read-only copy of the disk at a specific point in time. Locate the Victim VM  in the Azure portal and navigate to its disk. Create a Snapshot:  Select the “Snapshot” option for the disk . Make sure the VM is running, as snapshots can be created on active VMs. Choose Snapshot Type:   Select “Full” for a complete copy of the disk . Use “Incremental” if you’re doing routine backups. Name the Snapshot:  Assign a descriptive name ( e.g., victim) to avoid confusion in later steps. Azure storage costs apply to snapshots ($0.05/GB/month for standard and $0.132/GB/month for premium). For most investigations, snapshotting only the OS disk is sufficient . However, if the VM has data disks, you may need snapshots of these too. Step 2: Create a New Disk from the Snapshot The snapshot data now needs to be applied to a new disk, making it accessible for analysis. Create a Disk from the Snapshot:  In the Azure portal, go to “Create Disk” and select “Snapshot” as the source type. Name the Disk:  Name it similarly to the snapshot, adding -disk at the end (e.g., victim-vm-os-disk) for easy identification. Select Disk Type:  Choose Premium SSD for faster data processing speeds during forensic analysis. If cost is a concern, you can delete the snapshot after this step, but keeping it is advisable as a backup. Create Disk:  Confirm and create the disk. This disk now holds all data from the snapshot and is ready to be attached to a VM for analysis. Once created search for disks (You will find created disk there) Step 3: Create the Forensic VM To analyze the imaged disk, create a separate VM called the “Forensic VM” with adequate resources for your forensic tools. Select VM Specifications:  Choose a VM size with a robust CPU (4 vCPUs) and memory (16GB) to handle the processing demands of forensic tools. Create OS Disk:  During setup, the Forensic VM will have its own OS disk where you can install forensic software and store results. Data Disk Selection:   Under “Data Disks,” select “Attach an Existing Disk” and attach the disk you created in Step 2. If you forget this step, shut down the VM before attaching the disk to prevent corruption. Location and Region:  Make sure the Forensic VM is created in the same region as the victim VM disk for performance optimization. This VM will host your forensic tools, such as KAPE, and provide an isolated environment for analysis. Step 4: Mount the Disk in the Forensic VM Once the Forensic VM is running, access the imaged disk by mounting it. Access Disk Management:  In the VM’s Disk Management window, you will see: Disk 0: The Forensic VM’s OS disk (typically C:). Disk 1: Temporary storage (typically D:), which is not persistent. Disk 2: The attached disk from the victim VM. Bring Disk 2 Online:   Right-click on Disk 2 and select “Online.” Windows will assign a letter to each partition. Access the OS Partition:  The OS partition will appear as another drive (e.g., G:), which you can now investigate. Ensure you avoid writing to this disk during analysis to maintain the integrity of the data. If any corruption occurs, simply repeat from Step 2 using the original snapshot. Step 5: Run Forensic Tools on the Forensic VM With the disk mounted, you can now use forensic tools to analyze the image. Install Forensic Tools:  Tools like KAPE, FTK Imager, or any preferred forensic software can be installed on the Forensic VM’s OS disk. Perform Analysis:  Analyze the OS partition to retrieve relevant evidence. Remember that this disk is writable, so take care not to alter the contents unintentionally. If you need a point-in-time copy for future analysis, consider using the snapshot or taking another snapshot of the newly created disk. ------------------------------------------------------------------------------------------------------------- Optional: Alternative Snapshot Access Methods For scenarios that require additional tools, downloading the snapshot as a virtual hard disk (VHD) can be useful. Export the Snapshot:  Select the snapshot in the Azure portal, navigate to “Snapshot Export,” and generate a one-time URL for downloading. Use AzCopy for Speed:  To accelerate the download, use the AzCopy tool with the command: azcopy cp "--snapshot URL--" "c:\programfiles\snapshot.vhdx" --check-md5 nocheck VHD Advantages:  Direct VHD access enables automation and integration with tools that may require offline data access. However, be mindful of the potential data egress costs and long download times. Forensic VM Image Creation for Future Use To streamline future investigations, Azure offers ways to create and share VM images. Create an Image:  Create a VM with all your forensic tools installed, then save it as an image in the Azure Compute Gallery. This enables quick setup of similar VMs for future investigations. Use Azure Image Builder (Advanced):  If you prefer customization, use Azure Image Builder to craft an image from scratch. This setup is ideal if you need to transfer or reuse the Forensic VM across different regions, subscriptions, or resource groups. ------------------------------------------------------------------------------------------------------------- Summary Using Azure’s in-cloud investigation capabilities, you can create snapshots, build forensic VMs, and attach imaged disks to streamline your incident response process. By performing forensic analysis in the cloud, you can bypass data egress costs, reduce transfer times, and work efficiently on even large data sets. With this guide, you have a complete roadmap for setting up in-cloud forensic analysis and enhancing your response capabilities in Azure.

Since the 1950s, Iran has pursued nuclear energy, initially with Western support, aiming to harness nuclear power for electricity. B ut after the 1979 Iranian Revolution , m any countries grew wary, fearing Iran’s nuclear program might be a cover for weaponization. Concerns escalated when the International Atomic Energy Agency (IAEA) found evidence in 2003 that Iran might be pursuing nuclear-grade materials. Amid this tension, Stuxnet—a piece of malware created to interfere with nuclear capabilities —became the world’s first known digital weapon. ------------------------------------------------------------------------------------------------------------- How Stuxnet Disrupted Iran’s Nuclear Program Stuxnet was designed with one primary goal: to sabotage Iran’s nuclear enrichment by infecting specific computers controlling the centrifuges used for uranium enrichment . Centrifuges must spin at precise frequencies to enrich uranium. The malware targeted Programmable Logic Controllers (PLCs) managing this process, altering their behavior to subtly sabotage the centrifuges without immediately raising suspicion. One challenge was accessing these PLCs, as they were offline from the internet and heavily secured . But Stuxnet’s creators—reportedly backed by nation-states (likely the U.S. and Israel)— found a way around this. Stuxnet initially spread through Windows computers via infected USB drives, exploiting vulnerabilities that allowed it to remain dormant until it detected Siemens Step 7 software, which was used to program the Iranian PLCs . ------------------------------------------------------------------------------------------------------------- Stuxnet’s Attack Strategies: An Unprecedented Use of Zero-Day Exploits Stuxnet’s authors used four zero-day vulnerabilities —highly valuable and rare exploits that had no known fixes—to ensure it could infect, propagate, and escalate privileges across Iran’s networks. Here’s a closer look: USB Autorun via .lnk File Exploit (MS10-046) : Stuxnet used a vulnerability in Windows’ shortcut files (.lnk) to execute a malicious DLL file just by having the USB drive connected and visible in Windows Explorer. This zero-day allowed infection without any user interaction, exploiting older autorun behaviors in Windows. Print Spooler Service Vulnerability (MS10-061) : Another exploit enabled Stuxnet to spread across a trusted local network by compromising the Print Spooler service . This “worm-like” feature allowed Stuxnet to reach more systems quickly and without user involvement. Keyboard Layout Vulnerability (MS10-073 ) : Stuxnet needed higher privileges to make changes to critical files, and this local privilege escalation vulnerability allowed it to elevate its access on infected machines. Task Scheduler Vulnerability (MS10-092) : By modifying task files, Stuxnet could exploit the Windows Task Scheduler and achieve SYSTEM-level access, giving it near-total control over the infected systems. ------------------------------------------------------------------------------------------------------------- A New Era of Cyber Warfare Stuxnet’s design, sophistication, and reliance on high-value zero-days were a clear indication of nation-state backing, marking it as a new kind of digital weapon with geopolitical aims. By successfully disrupting Iran’s nuclear program, Stuxnet didn’t just attack computers—it sent a message about the power of cyber warfare, setting a precedent that digital weapons could now influence global politics. Stuxnet’s impact was profound, serving as both a technical and strategic innovation in cybersecurity and warfare. It forced the world to acknowledge that, in the digital age, malware could be used for not only espionage but also as a weapon with real-world effects​ ------------------------------------------------------------------------------------------------------------- Stuxnet: A Closer Look at the Attack Mechanisms Stuxnet's attack on Iran's nuclear enrichment facilities used a combination of zero-day vulnerabilities, rootkits, and PLC-targeted manipulation to disrupt centrifuge operations. 1. Overcoming the Air-Gap with Zero-Days To penetrate Iran’s isolated networks, Stuxnet utilized multiple zero-day exploits: MS10-046 (USB Autorun Vulnerability) : This exploit allowed Stuxnet to execute its code via infected USB drives without requiring user interaction. Once introduced to the network, the malware sought out computers running Siemens’ Step 7 software, commonly used in industrial settings. MS10-061 (Print Spooler Service Vulnerability) : After reaching the air-gapped network, Stuxnet spread to other machines by exploiting this vulnerability, which allowed it to propagate through the network using the Printer Spooler Service. The malware’s worm-like behavior was controlled, infecting only a limited number of machines and set to self-terminate by June 24, 2012, to limit unintended spread. MS10-073 and MS10-092 (Privilege Escalation Vulnerabilities) : Stuxnet used these vulnerabilities to escalate its privileges to SYSTEM-level, gaining full control over infected Windows systems and establishing persistence. 2. Concealing Its Presence with Rootkits Once SYSTEM-level access was secured, Stuxnet deployed rootkits to avoid detection : Kernel and User-Mode Rootkits : These rootkits were installed using malicious device drivers, which were signed with stolen digital certificates from companies like Realtek . The rootkits concealed Stuxnet’s files and processes, effectively hiding it from users and security tools. T arget-Specific Behavior : Stuxnet was designed to only target Siemens S7-300 PLCs connected to specific types of variable-frequency drives, particularly those used to control centrifuges. This targeting was tailored to equipment commonly used in Iran’s uranium enrichment facilities, limiting the malware’s potential to harm unrelated systems. 3. Command and Control (C2) Without Internet Connectivity Stuxnet operated within air-gapped environments but maintained basic communication capabilities: Primary C2 Domains : Infected systems attempted to connect to domains like todaysfutbol[.]com and mypremierfutbol[.]com , transmitting basic system information and verifying the presence of Step 7 software. Peer-to-Peer Communication via RPC : Stuxnet could update itself and exfiltrate information through a peer-to-peer network. Infected systems with internet access could pass along updates and data to isolated systems via RPC (Remote Procedure Call), allowing Stuxnet to function even without direct internet access. 4. Hijacking and Manipulating PLCs Stuxnet's most sophisticated attack involved directly manipulating Siemens PLCs: DLL Hijacking of s7otbxdx.dll : Stuxnet replaced the Siemens DLL s7otbxdx.dll with a modified version , intercepting and manipulating communications between Step 7 and the PLC. It injected malicious STL (Statement List) code into the PLC while concealing these modifications from operators. Frequency Manipulation : Stuxnet periodically altered the frequency of the centrifuge motors, forcing them to speed up or slow down, which caused physical damage to the centrifuges over time . The malware then spoofed the original frequency data to avoid detection by monitoring systems, creating the first-known rootkit on a PLC. 5. Targeted Criteria and Fail-Safe Mechanisms Stuxnet’s targeting was precise, avoiding interference with non-Iranian PLCs: Selective Interference : It only affected centrifuges operating within specific frequency ranges (807 Hz to 1210 Hz) and ignored systems that didn’t meet this criterion, minimizing collateral damage. Stuxnet also refrained from reinfecting systems that had previously been compromised.' Stuxnet’s Legacy Stuxnet was a groundbreaking cyber weapon that demonstrated the potential for malware to cause physical damage to critical infrastructure. Its design, incorporating stealth, selective targeting, and air-gap-penetration strategies, underscored the growing sophistication of state-sponsored cyber warfare​ ------------------------------------------------------------------------------------------------------------- Conclusion the Stuxnet attack stands as a groundbreaking instance of cyber warfare, demonstrating an unprecedented level of sophistication in both its design and its ability to evade detection.  Stuxnet set a precedent for future cyber operations by combining espionage, network infiltration, and physical sabotage. It underscores the critical need for advanced cybersecurity measures in protecting industrial control systems and highlights the potential reach and impact of cyber warfare on national infrastructure.

In recent years, the landscape of cybercrime has drastically changed, evolving from random attacks to highly organized, human-operated campaigns. Unlike traditional ransomware attacks, which were often opportunistic, human-operated ransomware is carefully orchestrated by groups that target specific organizations, often with a high level of planning and precision. 1. Human-Operated Ransomware: A New Level of Targeted Attack In the early days of ransomware, attackers often used “scattershot” approaches like phishing emails, aiming to infect as many victims as possible. However, some ransomware groups now conduct targeted attacks, sometimes called “human-operated ransomware.” Instead of random infections, attackers thoroughly research and choose victims, gaining access to networks and strategically deploying ransomware when it’s likely to cause the most damage. Key Steps in a Human-Operated Ransomware Attack: Initial Compromise:  Attackers typically gain entry through straightforward means: phishing emails with malicious attachments, weak or reused credentials, or exploiting systems with internet-facing vulnerabilities (like exposed RDP). Establishing Persistence:  Once inside, attackers often use t ools like Cobalt Strike (a penetration testing tool frequently used by attackers) to maintain access , or they may install “web shells” ( programs that allow remote access ) to give them backdoor entry whenever they need it. Privilege Escalation:  Attackers then work to gain more control over the network. They may look for saved passwords or use tools like Mimikatz to steal login credentials. Tools like Bloodhound and Pingcastle are often used to map out and find ways to escalate privileges within Active Directory environments. Reconnaissance and Data Collection:  Before encrypting data, attackers often steal sensitive information . This tactic, called “double extortion,” is a strategy where attackers can threaten to release stolen data if the ransom is not paid . Cobalt Strike scripts, nslookup, and other network tools are used to locate and gather valuable data. Lateral Movement:  Attackers spread across the network to infect more devices using tools like Cobalt Strike, Metasploit, and sometimes even old exploits like EternalBlue (which was part of the WannaCry attack). They may also tunnel RDP connections using ngrok or other services. Execution of Objectives:  After gaining full control over the domain, attackers reach their final objectives: Data Exfiltration:   Using FTP, WinSCP, or cloud file hosting services , they steal sensitive data. Ransomware Deployment:   Ransomware is deployed across the network via tools like WMIC, PSExec, and sometimes manually. This strategic deployment often occurs at a time that maximizes impact, such as during off-hours or holidays. --------------------------------------------------------------------------------------------------------- I have create a complete series on Ransomware from Evolution to impact. Might possible you know more than me But Who knows you might learn something new. Kindly do check under course tab -------------------------------------------------------------------------------------------------------- 2. LockBit 2.0: Ransomware-as-a-Service with a Double-Extortion Twist LockBit, first seen in 2019, resurfaced in 2021 as LockBit 2.0 , introducing new strategies and enhancements to ransomware deployment. LockBit 2.0 operates as a Ransomware-as-a-Service (RaaS) model , where the developers offer the ransomware to affiliates, who carry out the actual attacks. When a ransom is paid, both the developer and the affiliate profit, making ransomware more accessible to less technically skilled criminals. Key Tactics of LockBit 2.0: Double Extortion:  Similar to Maze, LockBit 2.0 leverages double extortion, where attackers first encrypt a victim’s files and then threaten to leak the stolen data if the ransom isn’t paid. Affiliate Program:  LockBit 2.0 actively recruits insiders within target companies to provide login credentials, like RDP access . This insider help streamlines initial entry into networks and often bypasses basic security controls. Network-Wide Distribution via GPOs:   Once the attackers gain access to the domain controller, they use Group Policy Objects (GPOs) to distribute the ransomware across the entire network . This allows them to disable security tools and push LockBit 2.0 ransomware to every connected device efficiently. StealBit for Data Exfiltration:  LockBit 2.0 includes a built-in tool called StealBit, designed to locate and exfiltrate sensitive corporate data. This feature automates data theft, ensuring maximum leverage over the victim. Rapid Encryption Techniques:  LockBit 2.0 uses advanced encryption tactics like multithreading and partial file encryption. These methods allow it to encrypt large amounts of data very quickly, making recovery more difficult for victims. ---------------------------------------------------------------------------------------------------------- Kindly Note The LockBit ransomware group has been significantly impacted by recent law enforcement actions under " Operation Cronos," involving international agencies like Europol, the FBI, and the UK's National Crime Agency (NCA). As of February 2024, several key LockBit infrastructure components have been taken down, including their Tor sites, and a series of high-profile arrests have occurred. These operations have disrupted LockBit's network, leading to a major loss of affiliates and a tarnished reputation, as the group has been forced to duplicate victim claims to maintain credibility. Authorities have arrested multiple LockBit affiliates, including those behind large-scale ransomware attacks . Charges were filed against prominent figures associated with LockBit and affiliated groups like Evil Corp, and several LockBit members have faced sanctions in the U.S., UK, and Australia. Notably, D imitry Yuryevich Khoroshev, allegedly the main operator of LockBit, was identified, and a reward was offered for information leading to his capture. Despite these efforts, LockBit has continued some operations , though their activity level and visibility have diminished, with some attacks attributed to the group potentially being exaggerated to mask the true impact of the takedown ---------------------------------------------------------------------------------------------------------- 3. Crypto Mining Malware: Silent Profiteers Unlike ransomware, which is loud and disruptive, crypto mining malware works quietly in the background. This type of malware hijacks system resources to mine cryptocurrency , potentially running for extended periods without detection. While crypto mining may seem less harmful, it can still cause major issues, draining resources, slowing down systems, and increasing power costs. Types of Crypto Mining Malware: Browser-Based Crypto Mining: Typically, this type is implemented through JavaScript on a website, mining cryptocurrency while the user is on the site. Many sites using browser-based miners are streaming sites or content portals where users stay for extended periods, maximizing the mining time. Host-Based Crypto Mining: This type of malware behaves more like traditional malware, arriving through phishing emails or malicious downloads. Once installed, it often uses PowerShell scripts or other methods to persist on the system, ensuring it can continue mining even after the system restarts. Though crypto mining may not seem as destructive as ransomware, some c rypto mining malware includes additional features like worm-like spreading capabilities, password stealing, and other data theft functions. This added functionality can allow attackers to sell compromised data or escalate attacks later, making crypto mining malware a threat that goes beyond resource theft. ---------------------------------------------------------------------------------------------------------- Key Takeaways: Staying Ahead of Modern Cyber Threats The rapid evolution of cybercrime demonstrates that organizations must adapt their security measures to meet these advanced threats. Here’s a summary of key strategies for defense: Enhance Network Security:   Segment your network to limit attackers’ lateral movement. Protect internet-facing systems with strong credentials and multi-factor authentication. Monitor and Detect Early:  D eploy endpoint detection and response (EDR) solutions to spot unusual activities like lateral movement, credential dumping, or unknown tools. Educate Employees:  Phishing is still a major entry point for attackers. Regular training can help employees recognize and avoid phishing attempts. Limit Privilege Escalation Opportunities:   Use tools like Bloodhound to identify and mitigate vulnerabilities in privilege management, and limit the number of users with administrative access. Patch Regularly:  Many ransomware attacks exploit known vulnerabilities. Keeping systems updated is one of the simplest and most effective defenses. Back Up Data:  Regular, secure backups are essentia l. They allow you to recover quickly without paying ransoms in case of a successful ransomware attack ---------------------------------------------------------------------------------------------------------- Akash Pate l

The Unified Kill Chain (UKC) is an evolution of earlier cyber kill chain models , addressing key limitations of traditional frameworks, such as the Lockheed Martin Cyber Kill Chain and Dell SecureWorks Cyber Kill Chain. It provides a holistic perspective on modern cyberattack s, emphasizing the complexities of advanced persistent threats (APTs) and multi-stage intrusions. By organizing an attack into three broad phases— Initial Foothold , Network Propagation , and Actions on Objectives —the Unified Kill Chain accommodates diverse threat scenarios , including insider threats and supply chain attacks. Limitations of Traditional Kill Chains The Lockheed Martin Cyber Kill Chain, introduced in 2011 , remains a v aluable model for understanding adversarial methods . However, its static structure reveals significant limitations in addressing modern, dynamic attack vectors: Payload-Centric Approach : The traditional model assumes an external payload delivery mechanism , neglecting the rise of insider threats and supply chain attacks . Lateral Movement Overlooked : Modern attackers often propagate through internal networks using t echniques like credential theft and lateral movement, which are inadequately addressed in the traditional framework. Inflation of Action on Objectives : Critical attack steps, such as privilege escalation and persistence, are grouped under "Actions on Objectives, " diluting their importance. To address these gaps, alternative frameworks such as the Unified Kill Chain were developed. ---------------------------------------------------------------------------------------------------------- Phases of the Unified Kill Chain The UKC defines 18 attack phases , grouped into three overarching stages : In , Through , and Out . 1. In (Initial Foothold) Focuses on breaching the organizational perimeter to gain initial access. Key Phases : Reconnaissance Resource Development Delivery Social Engineering Exploitation Persistence Defense Evasion Command & Control Example : An attacker performs phishing (Social Engineering) to deliver malware (Exploitation) that establishes a Command & Control channel. 2. Through (Network Propagation) Involves activities to escalate privileges and move laterally across the network . Key Phases : Discovery Privilege Escalation Credential Access Lateral Movement Execution Pivoting Example : Attackers use stolen credentials (Credential Access) to escalate privileges (Privilege Escalation) and pivot to other systems. 3. Out (Actions on Objectives) Covers activities for achieving the attacker's final goals, such as exfiltration or system impact. Key Phases : Collection Exfiltration Impact Objectives Example : Data is exfiltrated (Exfiltration) from compromised servers, or ransomware disrupts operations (Impact). ---------------------------------------------------------------------------------------------------------- Structure of the Unified Kill Chain The Unified Kill Chain divides an attack into three phases: 1. Initial Foothold This phase includes techniques used to gain access to the target environment . It encompasses reconnaissance and exploitation methods. Example Techniques : Phishing emails with malicious attachments or links. Exploitation of public-facing vulnerabilities, such as Log4Shell. Insider threats gaining unauthorized access using stolen credentials. Real-World Example : In the SolarWinds attack, adversaries used a compromised update mechanism to inject malicious code into thousands of victims’ environments. 2. Network Propagation Once initial access is established, attackers seek to move laterally, escalate privileges, and access critical systems. Example Techniques : Credential harvesting and Pass-the-Hash attacks. Exploiting trust relationships between systems, such as Active Directory misconfigurations. Deployment of remote administration tools like Cobalt Strike. Real-World Example : During the WannaCry ransomware outbreak, attackers exploited the EternalBlue vulnerability to propagate rapidly across networks. 3. Actions on Objectives In this final phase, attackers accomplish their goals, such as data exfiltration, sabotage, or deploying ransomware. Example Techniques : Encrypting critical files for ransom demands. Stealing sensitive data for espionage or financial gain. Disrupting critical operations by destroying system backups. Real-World Example : The NotPetya attack targeted organizations globally, encrypting data irrecoverably and causing billions in damages. ---------------------------------------------------------------------------------------------------------- Now we will look into Comparison b/w Unified kill chain and Traditional kill chain Unified Kill Chain vs. Traditional Kill Chain ---------------------------------------------------------------------------------------------------------- How to Use the Unified Kill Chain for Defense Organizations can leverage the Unified Kill Chain to strengthen their cybersecurity posture: Threat Detection : Monitor logs and network activity to identify patterns consistent with Initial Foothold techniques. Lateral Movement Prevention : Implement micro-segmentation and restrict unnecessary inter-system communication. Incident Response : Use the framework to categorize and prioritize remediation efforts based on the attack phase. ---------------------------------------------------------------------------------------------------------- Example Attack Mapped to the Unified Kill Chain Attack Scenario : Ransomware targeting a corporate network. Unified Kill Chain Phase Attack Steps Initial Foothold Spear-phishing email delivers a malicious macro document. Network Propagation Harvested credentials are used to move laterally via RDP and exploit SMB vulnerabilities. Actions on Objectives Files are encrypted, and a ransom note is delivered, demanding cryptocurrency payment for decryption. ---------------------------------------------------------------------------------------------------------- Conclusion The Unified Kill Chain equips organizations with a modern and robust framework for understanding and defending against complex cyberattacks. Its comprehensive, flexible, and actionable nature makes it an invaluable tool for enhancing cybersecurity resilience in an ever-evolving threat landscape.
