Two legends of the 2000s: BMW E46 M3 CSL & Porsche 997 GT3 CS. Arguably the finest driver’s cars of their era. Yesterday, I drove both back-to-back on winding roads. What a day! Raw, thrilling, and endlessly rewarding. Both unique yet united by pure driving joy.

After 13 incredible years at IBM, I’m stepping away to start building something new. IBM has been a defining part of my life. I’m especially proud to have founded and grown the Adversary Simulation team and to have served as a Distinguished Engineer focused on AI and offensive security. What began as a small idea became one of the greatest red teams, pushing the boundaries of what real-world adversary simulation can look like - made possible by an exceptional group of people I learned from every day. I’m deeply grateful to the X-Force leadership and to the teammates, mentors, researchers, and operators who made the journey what it was. The team is in great hands and will continue to do important, impactful work. Looking ahead, I’m excited to focus on building what’s next - continuing to raise the bar for offensive cyber and exploring how AI can enable high sophistication offensive cyber operations and capabilities at a speed, scale, and intensity never before seen. It’s still early, but I’m looking forward to sharing more soon. I truly appreciate everyone who’s been part of the journey.

@RoundtableSpace Red Teamer here, I can 100% confirm that when I hack I use nmap, I like to run apt update and apt upgrade, and call web vulnerabilities a Red Team, this will replace all the Yellow Team, Orange Team, Black Team, PlayStation Team, Xbox Team in CyberSecurity

@RoundtableSpace This probably goes so hard if you're a slopcoding dumbass that doesn't actually understand cybersecurity

@HackingLZ Who would have known that speaking to the people who are actually busy securing things have a better view on things than the one tweeting about their ideas? 😂

I’m not sure how I’d be successful at my job if I didn’t spend so much time on sales calls and after action calls. You could just read InfoSec Twitter and LinkedIn and form opinions, but those places are often pretty disconnected from what’s actually happening inside F100/500 environments.

Merz is exactly right. The Chinese, Indians and Turks were all buying Russian oil and defying sanctions before this decision. The only thing Trump’s move of lifting sanctions does is allow Putin to sell his oil at a higher price. It doesn’t change anything in the supply/demand equation which would lower oil price. A catastrophic move just when Putin was really starting to feel the economic pain.

The next public edition of my "Offensive Entra ID" course will take place from June 8th to 11th in The Hague! Tickets are now available via events.outsidersecurity.nl/entra-26-07/. Last time the tickets sold out in a few weeks, so don't wait too long if you want to secure a spot.

Great movie though! m.imdb.com/title/tt038780…
