Hello, It seems like things are very quiet and I only push gdbinit updates. Well, I have been very busy with very interesting projects, most of which can’t see yet the “light of the day”. Need to find some time to fool around with some new stuff. It seems that VMprotect is coming to OS X and that is exciting news. I hope they finish it soon since I am curious about Mac specific implementation and tricks....

Hello, Just posting a small update to gdbinit. A friend asked for colouring the registers changes as it happens in Ollydbg.

There is a single url in the program and some references to SHA256, this being a good indicator that they thought a little about security. I started playing the game and finally opened the safe....

These last days I must be set on a Apple devices destruction mode. First I lost access to my MacBook while trying to increase its physical security – I configured it to boot from network and I lost all access to boot sequence commands. I think my model has an EFI bug because the security-mode set to full doesn’t ask for a password when I start/restart my laptop, only asks for password if I want to boot from other devices....
