gdbinit v8.0: simultaneous support for x86/x86_64 and ARM architectures!

Here it is, a merge between the x86 and ARM versions of gdbinit. The only inconvenience is that you need to manually change the target, using the 32bits and 64bits commands for x86/x86_64 architectures, and arm for ARM. That’s a small price to pay for. This version features a lot of cosmetic fixes (indentation mostly) but also some fixes to the ARM related code, and a new command – dumpmacho. This command will dump the Mach-O header to a file....

gdbinit v7.4.4 – the skip command

Here is a small update to gdbinit with a new command, skip. This command will skip over the current instruction, without executing it. Usually I do it manually by set $pc=newvalue but this involves copy & paste and mouse movements and gets boring after a while. It’s great to skip over calls while you are trying some stuff and analysing some program behavior. By default it will not execute the command at the new address....

gdbinit v7.4.2, Github and Twitter

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....

gdbinit v7.4

Hello, Just posting a small update to gdbinit. A friend asked for colouring the registers changes as it happens in Ollydbg. I have enabled it by default (modify variable SHOWREGCHANGES if you don’t like it). I have also added a colour patch that Phillipe sent me – it will colour the 1st line of the disassembly (by default it’s off, modify variable SETCOLOUR1STLINE). Here it is a screenshot of both options enabled:...

A little vulnerability in The Heist iOS game or how to get (more) free Steam codes for Eets game!

MacHeist released a great puzzle game called The Heist, promising a prize when you managed to open the safe. Since I am a sucker for puzzle games I bought it and gave a brief check on its code. 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....
