A failed bruteforce attack on the EFI PIN lock of a MacBook Pro (orvtech.com) 9 points by orvtech 13y ago ↗ HN
[–] andrewroycarter 13y ago ↗ I wish there were more posts on HN like this. This is super cool, interesting, and a neat simple solution to a problem, even if it didn't work in the end! [–] orvtech 13y ago ↗ Yeah, it was my bad... I should have replaced the HDD with another one and kept his old data while trying this.I even use testdisk in an attempt to recover the HDD but had no luck. [–] cyberfart 13y ago ↗ I don't think recovery after dd would be possible. Also, why if=/dev/random and not if=/dev/zero? [–] orvtech 13y ago ↗ It is a link of this chains of bad decisions but I did not wanted the information to be recovered in any way.Testdisk managed to recover most information except that some part of the GPT were corrupted. [–] orvtech 13y ago ↗ Initially I though this lock resided on the disk only, specially since it had a nice UI. I thought "this cant be the bios" [–] X-Istence 13y ago ↗ Yay for UEFI.
