Massive thanks to Dr. Nestori Syynimaa for being able to get one of these cool badges! Coming in early-ish clearly was the right call 😂 Will be playing around with it alongside my bro to get it working (or break it more)



With a process that began two and a half years ago, I'm very excited to announce that I've written a book with No Starch Press! 🎉 "Practical Purple Teaming" tells you all you need to know to get started with collaborative offensive testing. nostarch.com/purple-teaming



I did a thing. Thanks Cloud Security Podcast for having me!

I love how when I'm testing CA policies I can just google around a bit and find Nathan McNulty 's detailed guides around some of the issues😂 P.S Also pro-tip for people playing with attributes remember that there is an Attribute assignment AND definition adm role

An in-depth look at the recently published EchoLeak vulnerability on M365 Copilot by Aim Security that could lead to data exfiltration just by sending an email to a user who uses Microsoft Office365 Copilot. youtu.be/Myf1cLsUxsk


Hey Nathan McNulty gathering some data and wanted to get your thoughts. On the topic of exclusions, what are the best approaches for Conditional Access in Entra and exclusions for endpoints in MDE in the context of a large enterprise? CA policies I'm a fan of Restricted AU sec
