Description

If you had always wanted to learn how to reverse and patch packed programs - without unpacking,  then this is the course for you. This course is a follow-up from the earlier course on Reverse Engineering & Memory Hacking. It is the practical application of what you have learnt in the first course. If you think that packing and anti-debugging is good enough to prevent reverse engineering, then you may be in for a surprise. In this course, I will show you how to test the effectiveness of several popular packers by packing crackmes and then reversing them - without unpacking.

Traditionally packed programs are unpacked before debugging is carried out. This is because a packed program's file cannot be patched. Much of software protection has centered on making it difficult to unpack programs. However,  the important question is: how effective is packing, obfuscation and anti-debugging as a means to prevent reversing? This course explores several packers to find the answers.

We will do the analysis using a tool called Cheat Engine, which is a prominent tool used by game hackers. This tool could also be used to study and analyze packed program's processes that is running in memory. You will learn how to perform debugging in spite of anti-debugging being implemented. There is no need to unpack and dump memory.  Instead of unpacking and then patching the dumped files and fixing IAT (Import Address Table) tables,  we will write scripts to hack memory using byte patching using an advanced technique called AOB (Array-Of-Bytes) Injection, by injecting code into code caves (inline memory patching).  In this course you will learn how to do all of the above and more.

At the end of this course you will be able to gauge the effectiveness of software packers, obfuscation and anti-debugging protection and also to have a good idea of how to implement extra countermeasures to improve the security of software.

In all the practical exercises and walkthroughs, we will use Crackme's which I have written. You will learn how to pack them using several popular packers and then hack them using Cheat Engine.


What you will learn

  • How to set hardware breakpoints and debug packed programs in spite of anti-debugging protection

  • Doing Break and Trace to identify Algorithms for reversing

  • Identifying addresses to do memory patching

  • Writing custom trainers (loaders) using Cheat Engine to hack and patch memory

  • Modify program behavior

  • Process Patching programs

  • Creating Lua Scripts for process patching

  • Test the effectiveness of Anti-Debugging technology

  • Packing crackmes using popular packers

  • Hack the packed crackmes and patch their memory during runtime

Prerequisites:

  • Before taking this course, you should preferably be already familiar with how to use x64dbg and Cheat Engine

  • Windows PC

  • Some knowledge of Assembly would be useful but not compulsory

So, go ahead and enroll now and I will see you inside!

The techniques shown in this course are clever and easy to execute. As a malware analyst, being able to analyze a Themida packed binary without unpacking it is unvaluble!
