Reversing Industrial Firmware...

Recommended Posts

usually there is a ROM you can only replace through voltage mode debug, and rarely even that, that has hashing and deflate code for unpacking and mapping images. If you can get past this it's usually trivial to patch and create custom firmware, especially on hardware with something like a J2ME profile so you can keep the ROM and just do your own java firmware or jar patch.

now days everyone like actel and arm are rolling out microcode for secure flashing and encryption oracles though, in some cases it's bulletproof without buffer overflows or ways of dumping..
