This is my main laboratory for practices.

Repository Structure

1. Reverse Engineering on CrackMes

Solutions, analysis scripts, and detailed write-ups for "crackme" challenges from crackmes.one.

• 1 - 2 Difficulty:

  • Fundamental reverse engineering concepts.
  • Techniques include basic static analysis (Ghidra), dynamic analysis (GDB, ltrace), memory inspection, and handling ASLR/PIE protections.

• 2 - 3 Difficulty:

  • Focuses on intermediate reverse engineering tasks.
  • Techniques involve "Keygening" (writing custom key generators), algorithm reversing, and unpacking binaries.

2. Hardware Practices

Practical hardware security stuff like BIOS dumping and firmware analysis.

• SPI Flash & BIOS Chips: Projects involving dumping and analyzing BIOS firmware, such as the Macronix MX25L6473E chip.

3. File Compression

My journey on learning file compression algorithms.

Tools & Environment

The analyses are made by using these tools:

• Disassemblers/Decompilers: Ghidra
• Debuggers: GDB (GNU Debugger)
• Binary Analysis: strings, ltrace, strace, readelf, binwalk, UEFITool
• Scripting: Python
