About#

I am Rahul Razz, a Computer Science undergraduate at IIT Bhilai and a part-time CTF player with Team Nova.

My current focus is low-level security: binary exploitation, reverse engineering, cryptography, Linux internals, and firmware analysis. This site is where I publish writeups, research notes, exploit development notes, and projects that are useful enough to survive beyond one terminal session.

Current Work#

Competing in CTFs with Team Nova since April 2025
Solving pwn challenges involving memory corruption, heap exploitation, and FSOP
Working on firmware reverse engineering for hardware security assessment
Studying bootloaders, secure boot flows, and firmware integrity checks
Documenting exploit strategy with GDB, pwntools, IDA, Ghidra, and Binary Ninja
