#2Neat little device, looks like a Yubikey clone. One could get a similar device by hacking a Logitech unifying receiver, which contains a ..16MHz 8051 clone in it, and a radio to spare.

thats ultimately the intent, to build a Yubikey-like security key, with everything open down through the firmare to the details of the soc

#4would it be difficult/possible to use this as a smart card with the proper code?

#5also great for espionage

well.. I'd probably disable the flashing LEDs. But, that aside, I too thought "oh cool... a complete ARM system in my USB.. what could possibly go wrong here" But, the other side of this is: this is precisely what every closed-box USB device I plug into my USB potentially IS. This is just the overt "hi I'm an awesome tiny computer" state we're actually living in, all the time
TL;DR how do we know we aren't exposed to these devices all the time?

Want. Want that, and SSH keystore, and 2FA boss.

At some point won't you run into IP issues with the ARM SoC? Plus how would you deal with things like power analysis attacks that require modifying hardware to fully mitigate?

One key (pardon the pun) requirement of a 2FA key is that it can't be cloned - how would this be prevented? Can the microprocessor be locked to prevent reading its flash memory?
