The DEF CON 27 Blue Team Village badge is a portable WiFi honeypot in the form of a wearable electronic conference badge. The badge was built for the DEF CON Blue Team Village and granted badgeholders access to an event with exclusive threat intel sharing panels comprised of industry luminaries.

It initially started as a small side project but then quickly transitioned into a personal challenge to conquer and to learn medium-scale electronics manufacturing and design, all while not neglecting the badge’s defensive security purpose. The bulk of the components were placed at a PCB assembly house overseas and the remainder assembled by hand in the US. Each badge ran Linux with honeypots cowrie (SSH) and honeydb (many services). Honeypot data was collected from a master controller badge on a periodic basis.
