Reverse Engineering Challenge: Silent Oracle
A walk-through of an HTB Neurogrid reversing challenge where you analyze a stripped 64-bit PIE binary in Ghidra, identify a hardcoded comparison function, discover the local flag is a decoy, and brute-force the real flag from the remote service using a Python script that tests prefixes based on response differences.
HackTheBox -- Imagery (MEDIUM) Experience
I’ll walk through my experience tackling the HackTheBox "Imagery" CTF (Medium). I'll showcase my thought process, tools, and methods as I work through each stage — whether I succeed or hit roadblocks. The goal isn't just solving it, but highlighting how I approach challenges and sharpen my skills along the way. As of now this machine remains unsolved.
