[Linux Reversing] Linux Patching helper demostration video

Hello all mates,

I’m currently working on a small project named Linux Patching Helper , created in Pascal/Lazarus using qt, which aims to apply the method i used to crack some sommercial Linux applications (you cand find my RAR patching tutorial here). This tool is based on objdump, and it will dump data + code and then start tracing the code. Still on development and here is a demostration video to show how it works.

The target in this video is a download manager for Linux (comparible to IDM in windows) named FlareGet, but only for testing purposes, therefore cracked version will not be released:

Hope that i can release it soon, because there are some issues with memory management, the tool takes high memory consumption while executing, and i’m trying to fix. But don’t expect too much, because it’s only my hobby, only for fun 🙂

 

Regards

Levis
