We just hacked @donie (with his consent) and here's a breakdown of how we cracked his password. At a high level, we used a data breach site, the password cracking tool @hashcat, and a custom wordlist and ruleset. This is how it went down.

Great writeup of reversing and troubleshooting a malfunctioning Beaglebone Black

Lots of tools and techniques used (UART, JTAG, Saleae, EMIF Tuning, tinySA, ARM Reversing, etc.)

Finally published my writeup of my reverse engineering the TI AM335x boot ROM. (At least, as far as it served to help me get the boards to boot.) This is the processor at the core of the Beaglebone Black board.

I've uploaded the keymaster key for the @socialproofsec clue hunt, for the few that asked for it. Looks best with various exotic @ fun PLA filaments. I recommend @Proto_pasta and @Polymaker_3D.
