Was there anything on the electronic badge? I like that the challenge didn't require bringing a ton of not-at-all-TSA-friendly EE equipment, but is there a good link to what was up with the badge beyond it being an Intel Quark?
- resonanttoe 10y agoI overheard someone talking about there being timed strings outputted to the serial lines on the badge (And the TX, RX and GRND pins were not together) but take that as conjecture and I was too shit/lazy to check while there, so unconfirmed here. I'm surprised that solving the badge didn't utilise anything that was in the badge.
- tonyarkles 10y agoI brought a pretty minimal set of tools, and I was surprised that I had no additional scrutiny! I think they maybe scanned my bag more than once, but that's about it. For an idea of what I had, this is off the top of my head: Bus Pirate, Bus Blaster, 2xRTLSDR, extra USB-WiFi, multimeter, screwdriver set, probably 4 ethernet cables, small travel router, several antennas (which showed up pretty cool on the x-ray!), hmmm... I think that's about it. And I was travelling from Canada.
- junkmail 10y agoIt was a bit odd that the badge did not have any significant connection to the challenge this year. In past years, there was enciphered text that was viewable either with the correct button presses, or by dumping the ROMs, which was used as parts of a needed OTP. It was also a new-to-DC x86 processor. It did output strings of text on a serial pin (GPOI01 ? if memory serves). I was (wrongly) guessing that the badge would have been like a chip-and-pin credit card, requiring certain inputs to get proper outputs. Again I was overthinking!
