How an hardware is actually vulnerable to exploitation?

« on: September 30, 2010, 11:11:36 AM »

I am just new to these hardware hacking field,
I am just wondering about this field,How actually an hardware is subjected to exploitation?

In software we have incorrect handling of input in the source,so we get some buffer overflows and things,but i don't know what bug's actually present inside the hardware for exploitation?

Also can a hardware exploit can get us remote code execution?

Need a bit of explanation to make my self-clear...

hope i will get some...

Normally hardware hacking boils down to exploiting firmware, code embedded in chips etc...
I have not seen messing with the hardware resulting in a vulnerable state until I read about geohot's glitching the memory bus hack... Though geohot's work was significant, in the end it was a heap overflow that opened the iron gates of PS3...

One of my recent faves is the jedi packet trick. Check out the CanSecWest 2010 presentation at http://www.alchemistowl.org/arrigo/Papers/Arrigo-Triulzi-CANSEC10-Project-Maux-III.pdf

Ahh... hardware exploitation. Take a look at Chris Tarnovsky's work. This guy blows my mind. Chemistry, precision mechanics, and code.

PS - Didn't realize I dug up a rather old thread. Sorry, mods.
