This is my main laboratory for practices.
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.
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.
My journey on learning file compression algorithms.
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
