New adventure: wrapped week one at Microsoft Security! Working alongside @dwizzzleMSFT, who I plan to annoy with a backlog of questions. Excited to work on AI and security at planet scale 🤓

After 10 years at Elastic/Endgame, today is my last day.

Incredibly proud of what this small but mighty team has built. Working alongside our community of users has been one of the most rewarding parts of the journey.

On to a very exciting new adventure soon, stayed tuned!

Engineers at Microsoft have been busy. Today they patched 5 LPE vulns I submitted to their bounty program. All found with AI (not Mythos 😛)

We open sourced the tool used to detect the Axios supply chain compromise! I built it Friday after a red eye home from RSAC. Also, wrote up the full story, including the hectic moments after that first critical alert
