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!
Who this course is for:
- Anyone who wants to know how to assess the effectiveness of packers against Reverse Engineering
- Software Developers who want to implement extra layer of protection in addition to packing and Anti-debugging
- Reversing hobbyist who wants to level up their skills to take on packed software
- An introduction to Software Protection for anyone who wants to get started in this field
