Description
In case you had all the time needed to find out how to reverse and patch packed applications – with out unpacking, then that is the course for you. This course is a follow-up from the sooner course on Reverse Engineering & Memory Hacking. It’s the sensible utility of what you might have learnt within the first course. In case you assume that packing and anti-debugging is nice sufficient to forestall reverse engineering, then chances are you’ll be in for a shock. On this course, I’ll present you check the effectiveness of a number of widespread packers by packing crackmes and then reversing them – with out unpacking.
Historically packed applications are unpacked earlier than debugging is carried out. It is because a packed program’s file can’t be patched. A lot of software program safety has centered on making it troublesome to unpack applications. Nevertheless, the essential query is: how efficient is packing, obfuscation and anti-debugging as a method to forestall reversing? This course explores a number of packers to seek out the solutions.
We are going to do the evaluation utilizing a device referred to as Cheat Engine, which is a outstanding device utilized by sport hackers. This device may be used to check and analyze packed program’s processes that’s operating in reminiscence. You’ll learn to carry out debugging regardless of anti-debugging being carried out. There isn’t a must unpack and dump reminiscence. As an alternative of unpacking and then patching the dumped recordsdata and fixing IAT (Import Deal with Desk) tables, we are going to write scripts to hack reminiscence utilizing byte patching utilizing a sophisticated method referred to as AOB (Array-Of-Bytes) Injection, by injecting code into code caves (inline reminiscence patching). On this course you’ll learn to do the entire above and extra.

In all the sensible workouts and walkthroughs, we are going to use Crackme’s which I’ve written. You’ll learn to pack them utilizing a number of widespread packers and then hack them utilizing Cheat Engine.
