Mac EFI PIN lock brute force attack (unsuccessful)

Mac EFI PIN lock brute force attack (unsuccessful)

You can read his back story at the link above. He had the chance to enter a 4-digit pin before the format process. Now that he’s wiped the drive the code is at least 6 characters long, which is a lot more possibilities (at least it’s numeric characters only!). To automate the process he programmed this Teensy board to try every possible combination. It worked great on a text editor but sometimes the characters, or the enter command wouldn’t register. He guesses this was some type of protection against automated attackers. To get around the issue he added different delays between the key presses, and between entering each code. This fixed the issue, as you can see in the clip after the break. Unfortunately after two 48-hour runs that tried every code he still hasn’t gained access!
