Electronic conference and indie badges are becoming increasingly popular. The creators of these badges often unintentionally release details about their designs before the event starts. This can often be enough information to start crafting a hack for the badge, leading to a large advantage if the conference holds a badge hacking competition. In this talk I'll go over my techniques for hacking badges pre-con, including the original Bender Badge and the BSides PDX Badge. I'll also show off a man-in-the-middle tool for badge add-ons, allowing for the monitoring and manipulation of i2c traffic on the badge. I'll recount my adventure hacking the Thotcon 0x9 badge and repurposing it as a morse code repeater to win second place in the Thotcon 0x9 CTF.
