ZTE ZXHN H298A Home Gateway – Hardware Recon & Boot Process Analysis
An initial hardware security assessment of the ZTE ZXHN H298A home gateway focusing on physical access, UART discovery, and boot process analysis. This post documents the methodology, extracted bootlogs, observed security mechanisms, and limitations encountered, with proposed next steps for deeper firmware and bootloader analysis.
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.
