I still have hexadecimal dice for anyone who wants one and talks to me. I will probably mostly be near the hall h sos stage in a bean bag chair after this talk, though might divert for a bit for the cheating at ctf talk.

I do network forensics and bot detection professionally, and otherwise a bit of applied cryptography (build and break), bureaucramancy (gdpr application, taking the british government to the european court of human rights for gender, basic stuff), cursed hacks, computer adjacent art, and queer stuff.

Wearing my starfleet uniform (tng, operations gold) until it gets too warm, and a red eff tshirt.
