Reverse Engineering Basics

Reverse engineering challenges ask you to recover the logic of a compiled program and find the flag.

In progress

This category is being written. Planned topics:

• Executable formats (PE / ELF) and the compilation pipeline
• Static analysis with IDA and Ghidra
• Dynamic debugging with x64dbg, gdb and Frida
• Recognizing common encryption and validation routines
• Packers, obfuscation and anti-debugging
• Python bytecode, Android, .NET and WebAssembly

Study tips

1. Understand how C code maps to assembly instructions.
2. Combine dynamic debugging with static analysis.
3. Practice algorithm recovery and collect signatures of common crypto routines.
