Here’s a capture of the output from FTDI. If you have suggestions please let me know in the comments! I don’t have a programmer with me so not sure how I can make a firmware dump. When I hit on 57600 8N1 I get “COME AND PLAY A GAME WITH ME”. I fired up minicom and played around with the settings. They affect the four LEDs above the central letters. The DEFCON letters are capacitive touch.Bottom left there is an FTDI chip (can’t read numbers).Tiny dfn8 package next to that has numbers (3336 412).It’s a 4-pin package with a shiny black top that has a slightly smaller iridesent square to it. Looks like an EEPROM to the upper right of the processor? (412W8 K411).Tere are huge images available after the break. But now I’m back in my room with a USB cord to see what might be done with this badge.įirst the hardware I need a magnifying glass but I’ll tell you what I can. I spent the rest of the afternoon running into people, and I took in the RFIDler talk. It took a measly 2-hours in line to score myself entry to DEFCON and this nifty badge.
