DEFCON'S NEW BADGE IS A SECURITY KEY YOU CAN SEE INSIDE

Summary from the TLDR InfoSec newsletter

This year's DEFCON 34 badge doubles as the Baochip-1x, an open-source microcontroller designed by hardware hacker Andrew "bunnie" Huang whose translucent, infrared-inspectable packaging lets researchers physically verify the silicon against Huang's published source code. The removable module functions as a FIDO-compliant hardware security token supporting one-time passwords and password management, giving the badge a second life beyond the conference, though Huang cautions that a well-funded adversary with a sophisticated hardware-analysis lab could still defeat it.
