Apocalypse Now movie poster
#Defconmovienight is Saturday, Feb 28 at 8pm PST. Please join us for 'Apocalypse Now' in honor of the passing of screen legend Robert Duvall. We'll be in the movie-night-text channel of the #defcon discord (Discord.gg/defcon) with movie chat and hangout vibes.
At @defcon.bsky.social last summer, hackers of all kinds convened to share #cyber research. The Hackers’ Almanack translates this work into plain language to give policymakers a window into the latest in offensive AI, cybercrime, critical infrastructure vulnerabilities & more.

oh cool, the hackers' almanack from def con 33 is out... and seems like they think policymakers should know about our snitch puck research?
(i agree, naturally, but the outside validation is nice)
