[Oliver] wiped the hard drive from a Macbook Pro using the ‘dd’ command on another machine. This does a great job of getting everything off the drive, but he was still faced with the EFI PIN lock protection when he tried to put it back into the Mac. You used to be able to clear the NVRAM to get around … Read the rest
[Leland Flynn] did a great job of picking apart the firmware image for a Westell 9100EM FiOS router. Unfortunately he didn’t actually find the information he was looking for.

With a couple of RPi boards on hand [Travis] was searching for more hacks to try with them. This made a great little test to see how the board performs with the well established attack.
To start he booted … Read the rest
[Adam Laurie] spent time tearing into the security of the SAM7XC chip produced by Atmel. Even if he hadn’t found some glaring security holes just reading about his methodology is worth it.
