Eeshan AgrawalChecking Santa's List Twice (With Python & Assembly!) 🎅💻
Just cleared "Weak 01" of #AdventOfPwn 2025 on pwn.college! 🚩
The challenge used thousands of addb and subb instructions to obfuscate a 1024-byte check. I used objdump for static analysis and wrote a Python parser to "undo" the math and recover the flag.
Skills: ✅ Reverse Engineering (x86) ✅ Static Analysis ✅ Python Scripting
