Why It Mattered

It adds an Asia-Pacific root record for conference badges that are not only wearable art but also embedded-security challenge targets tied to sponsors, LEDs, TrustZone separation, and public exploit documentation.

Hardware

The event page describes an electronic board badge based on Taiwan imagery with unlockable LED lights. The challenge deck documents 24 LEDs, 11 patterns, a command-line interface, ARM TrustZone on an M2351-class MCU, non-secure and secure execution stages, and challenge state stored across secure/non-secure boundaries.

Software & Apps

The public deck and repository point to released source code, firmware, hardware design, and exploit material. The badge command line exposed commands such as show, info, unlock, setname, clear, ping, ls, cat, echo, alias, whoami, and help.

Lore

HITCON tied the badge to booth participation: solving the board puzzle or completing sponsor challenges unlocked LEDs, and unlocking all county/city LEDs gave attendees a chance at the HITCON lottery game.
