We all love those electronic conference badges, don’t we? This talk illustrates the selection, design and implementation of a Zigbee enabled conference badge for the Mid-Atlantic CCDC competition. This year’s theme for the MACCDC was Smart Grid, so we wanted to give every participant (both Red and Blue teams) badges as score-able, hackable, in game assets. There were significant challenges along the way, from selecting hardware, programming in a single threaded environment, sniffing Zigbee and translating that into a score as well as making the “Open Smart Meter” badge hackable AND defend-able in just 2 days with folks that have little to no experience with Zigbee or micro-controllers. We’ll do some live demos of traffic, capture and the nightmare that is in game scoring. We’ll examine some of the red team hacks, blue team defenses and show you where you can get all of the goods so YOU can build a better badge and game for your next adventure.
