His excitement and deep interest in things from cisco to web security to life was inspiring.

A true hero and legend. RIP.

Loved his CISCO talks. RIP.

What sad news.

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.

It's been a long time, but I've always cherished our late night conversations at the Alexis Park. Truly a great hacker. RIP my friend

World got a little darker today. Rip my friend.

While he was a dividing personality with strong opinions, he had his heart in the right place

RIP
