How hackers crack software // Reverse engineering a program and writing a keygen for it
In this video, we're gonna be taking about what's reverse engineering and how to reverse engineer. We'll also talk about disassemblers and decompilers and how they work, and we'll be reversing a crackme from scratch. We'll see how can we patch executables using disassemblers like ida and binary ninja. Also we will be using ida decompiler to reverse engineer the whole key-checking algorithm and then we will write a keygen for it.
