A fun fact about this bug is that we only had an (entirely internally imposed) ~ 8 hour deadline to find it. Looking forward to sharing more info about it.
Serious bugs often occur in third-party components integrated by other software. @ifsecure and I found this vulnerability in the Dolby Unified Decoder. It affects Android, iOS and Windows among other platforms, sometimes 0-click. https://t.co/LchMIdKP0P

How to win at egg hunt: choose the character you're currently raising for your party, and make sure it has full happiness. Under this condition there's a 10% chance to get 9 eggs. Conversely, at empty happiness there's a 10% chance of injury.

Some personal news: I'm thrilled to be moving back to Project Zero! Specifically I'll be joining the Big Sleep project to find vulnerabilities in JavaScript engines. We've already found and reported our first vulnerability in V8 last week:

That time when @tehjh was just reviewing a new Linux kernel feature, found a security vuln, then went on a journey to see if he could exploit it from inside the Chrome Linux Desktop renderer sandbox (spoiler: very yes) https://t.co/Atc6toEdAj
