Little goblin with catears.

Unfinished projects, complaining about computers, reinventing the wheel (badly), has not fully read any docs since 2015. IT Security, scripting, maybe electronics?

Ask me about missing authorization checks on api objects.

I am eminently qualified to speak from experience about a variety of dumpster fires.

ICS cybersecurity person, @pancakescon organizer, martial artist, marksman, humanist, level 14 Neutral Good rogue, USAF retired. Speaker available for gigs.

Gin connoisseur. Rodent parent. Some dipshit from Chicago. Now an immigrant in Melbourne.

I post *very serious* things about infosec. Thoughts are entirely my own.

Infosec, Psychology+SE, OSINT, Privacy, Planes (), NJ, Linux, Geopolitics and Environmentalism etc.

Huge SciFi fan 🖖

Just a cold robot on the internet hacking, shitposting, helping and doing things

I joke. A lot.
I post about planes and ATC stuff. A lot.

Pretty unfiltered, thoughts/opinions my own not my employers. Probably overanalyzing things... Or am I? What does that really mean? Maybe if I calculate the optimal amount of analysis...
