Some of the situations I have worked on in the past included:ġ) Application logic patched to accept any serial keyĢ) Use breakpoint-analysis to step through the application and find a serial key from inside the debugger windowsģ) Decipher the serial-key generation and create a key-generator to produce infinite product keysĪs you can see here is a sample crack-me, “passwordapp.exe”. Let me show you how a simple crack-me exercise, which has a particular serial key (obviously unknown to me) can be patched for making it accept any serial key)Īny application can be patched/ cracked in multiple ways. They are programmed by other reversers as a legal way to “crack” software. For cracking and reverse engineering, it is often the primary tool because of its ease of use and availability any 32-bit executable can be used by the debugger and edited in bitcode/assembly in realtime. ![]() 8 It is often used by crackers to crack software made by other developers. ![]() You can download loads of crack-mes for hands-on practice from Ī crack-me is a small program designed to test a programmer’s reverse engineering skills. OllyDbg is often used for reverse engineering of programs. In this article, we will see a hands-on tutorial for patching an exe file to accept any serial key! Reverse Engineering is an fascinating art of playing with low level code. ![]()
