Guide [Breaking Security]How to disable syscall (anti-debugging protection)

78 posts in this topic

Recommended Posts

I made this tutorial in April of 2015 for the cheaters here and after almost a year of it being private I decided to post it to the public.

 

Gameloft always uses syscall on their games, and while this was written in April, MC5 still has removable syscall and you can use MC5 to practice :)

 

Requirements:

- IDA Pro

- Modern Combat 5

- GNU Debugger from cydia.radare.org (repo)

- OpenSSH

- Clutch 1.4.7-2

- armv7 binary of MC5, crack it on a 32 bit device for it to be armv7. I won't post one here because of copyright issues.

 

Below this line is the exact text I wrote on April 10, 2015. Enjoy :)
