.@joswr1ght just announced a 720-page modern incident response book. 18 months in the making. The first comprehensive update to foundational IR frameworks since 2001. Released to the community for free. “Someone asked me, ‘Do you like writing?’ I say, ‘No, I like having written.’ That’s a different thing altogether. But I wrote this book because I kept seeing the same problems over and over again.” This is what giving back looks like.

Today I’m launching Threat Hunting Labs.

Over the years I’ve analyzed many real-world intrusions. One thing became obvious: most training platforms don’t resemble how investigations actually happen.

So I built something different.

Threat Hunting Labs focuses on investigation-driven learning using real telemetry and structured investigative paths.

If you want to get better at investigating breaches, you should practice investigating breaches.
