Hack Hack Hacking with Adam Laurie

I have recently been listening to podcasts dealing with security issues(ie Hacking) and I recently came across a fantastic episode of Sploitcast with the infamous Adam Laurie(guy who hacked just about every device from cell phones to the UK Passport). This guy is amazing.

The episode covers everything from hacking RFID, bluetooth, infared, underground nuclear bunkers and even the politics of Hacking vs Cracking.
