We really should be talking about this more....KASLR is just not working properly on Android right now, and it hasn't for a long time.

A look back at our ninjas' first day at @Hexacon!
We are proud of our experts Quentin and Etienne, who are leading the ‘iOS for Security Engineers’ training course.
At the same time, Matthieu and Paul are hard at work on the ‘Azure intrusion for red teamers’ training course!
Happy training 🎓

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)
