I have been pretty busy helping organize HackTheSea for DEF CON 27. This will be the first ever maritime and ship hacking village at DEF CON. We are going to have a team CTF on a very nifty "ship" environment provided by Fathom5. There will also be a series of workshops for n00bs to maritime ICS/OT with lots of gear available for hacking practice. Our CFP is currently open, but closing soon for those doing original research in high seas hacking. In keeping with the DEF CON theme this year, Technology's Promise, we will also have Seasteading Institute on hand to talk about living at sea and to kick-off a hackathon challenge for the Seasteading Community.
Plus, lot's of pirate meme stuff.
