I Use AI Every Single Day. The Hugging Face Breach Still Scared Me.
I want to be upfront about where I'm coming from before I say anything else: I'm not an AI skeptic. I run AI agents most of my working day, and I've built plenty of them for different tasks. I use them for a lot — building internal tools, troubleshooting, you name it. Half the projects on my plate right now exist because an AI agent worked alongside me, troubleshot with me, and knocked out in a few days what would've taken months. So when I say the Hugging Face breach worried

What Is RunReveal?
The Problem Nobody Loves Admitting Every SOC analyst I know has a version of the same complaint. Splunk gets expensive the moment your log volume grows past whatever number your finance team quietly panicked about last renewal.

Networking: VPC, Flow Logs, and Cloud DNS
Where the traffic actually went — and why GCP's network model means one VPC can span the whole company.

Get this wrong and you'll scope an incident to a single project when the network the attacker actually moved through spans half th

An employee's VPN client wouldn't connect on their managed Mac. I

Cloud Storage: Bucket Access, Evidence, and the Public-Exposure Problem
GCS buckets are both a common source of evidence and, misconfigured, one of the most common ways data actually leaves a GCP environment. Cloud Storage shows up in almost every incident twice: once as a target — the thing the attacker was actually after — and once as a source of evidence, if you configured it right beforehand. This article covers both sides: how bucket access actually works, how to tell if an attacker exfiltrated data through a bucket, and how to collect GCS o
