Dumping the flash of the Syscan 2015 badge

The badge of the Syscan 2015 conference included an ARM-based STM32F030R8 processor running some challenges. Although SWD pins are accessible on the badge, some have noted that the STM32 is readout-protected, meaning that it will refuse to dump its flash memory.

Fortunately, two researchers (Johannes Obermaier and Stefan Tatschner) recently published a paper at the WOOT '17 conference, in which they reveal a vulnerability allowing to bypass the readout protection. Their technique allows to dump the flash one DWORD at a time, rebooting the CPU between each access.

I implemented this attack using a BusPirate and the PySWD module. Here is a quick'n dirty PoC to
