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.
A true legend.
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.
It was thin to find out the differences between the two.
Though, FeFe also suffered some health issues lately, IIRC?
fx = Felix Lindner
Please don't mix up the names and nicknames.
Both are highly renowned security experts.
Thank you felix for everything you did for mob :)
