DESCRIPTION:While busy hacking the planet\, have you ever encountered an un
 familiar architecture and simply had no idea where to start? You pried the
  firmware from a reluctant (and almost not smoldering) flash chip\, loaded
  the thing in IDA\, but what's next? \nWe got into this pickle while worki
 ng on reversing the firmware of a medical device. The mystery architecture
  turned out to be M32C\, and thankfully\, IDA Pro added support for it a f
 ew months prior.\n\nThis talk is not exactly about reversing yet another e
 mbedded device. Instead\, this is more about the journey and lessons learn
 ed so that it could be abstracted away for the next project. Rather than f
 ocusing on the specifics of the firmware itself\, we will see how it inter
 acts with the micro-controller and the steps taken to approach an unfamili
 ar embedded architecture. \n \nDuring this presentation\, you can expect d
 igging into low-level micro-controller notions such as interrupt handlers\
 , special purpose registers\, how to find flash handling code\, and way to
 o much M32C assembly. \nIf you've ever dabbled in hardware hacking and wan
 t to have a look at something that is not Linux-based\, this talk will giv
 e you some pointers in how to get the ball* rolling. \n(*not talking about
  the ones we dropped at the reballing station)
