Leading online #policy & #enforcement for 40 years. I left as head of Safety and Advocacy for #OkCupid after 9 years with #MatchGroup where I worked in T&S, data governance, legal compliance, DEI, realistic wellness, and ethics then became a #Whistleblower

Formerly worked in IT Security. Probably the world's first non-US-government hacker-catcher, head of commercial security for British Telecom, 2nd (and longest serving) #IRC Operator outside of Finland - And all that #MUD & #MIST stuff.

Tinker, Sailor, Biker, Hi

I do industrial security research for a living, mostly looking for #vulnerabilities in all of the wrong places. I like reverse engineering how PLC logic systems function under the hood, learning how safety instrument protocols work, and figuring out what malicious threat groups are doing and can do with access to such systems. A long time ago, I invented the term 'foreverday' to describe unfixable vulnerabilities.

Occasionally I analyze #industrial #malware, too, and on very rare occasions encounter threat groups that actually write malicious logic to do the vile things that I like to learn about.

I work for a little startup in the space called Dragos. In my spare time I enjoy long distance #bicycling, #sailing, and doting on our #pets.

I used to have an account on :birdsite:, however I haven't used it in a while and you should no longer assume that it's under my control.

Trying not to be one of the 80% that can be moved in either direction.
