I met FX many years ago during a Black Hat event. At the time, I was working on a class of vulnerabilities related to zip archives. Not only did he know exactly what I was on to, but he was able to articulate the actual issue and explain what was happening behind the scenes and why my exploit was working.
I had hoped that after his illness he would be granted some time for personal life and recovery — which makes this news all the more shocking.

A true legend.
He's struggling with some health problems, too - but his colleague reported in a Mastodon post that he's improving.
It was thin to find out the differences between the two.
Though, FeFe also suffered some health issues lately, IIRC?
RIP
Thank you felix for everything you did for mob :)
Are you sure it was him? And not an external, perhaps undocumented and extremely illegal, system affecting his actions and behaviour?
