This page contains Cyber Apocalypse 2025 CTF writeups, covering all challenges in the forensics category.

The writeup analyzes Lobster Stealer, a macOS malware that steals sensitive data like passwords, browser history, and cryptocurrency wallet info. It uses RC4 for command obfuscation and AES-128-CBC for encrypting flag. The challenge involves decrypting the flag by analyzing the malicious OSA script and extracting encryption keys from a PNG file.

This page contains writeups for Wargames.MY 2024 CTF, covering challenges in Crypto, Forensic, and Misc categories. Solutions involve decrypting ROT13-encoded passwords, extracting flags from ICMP packets, decrypting SMB traffic using NTLM hashes, repairing corrupted JPEG images, and rearranging metadata from a .dcm file based on given indices. Each solution uses tools like CyberChef, Wireshark, Hashcat, and Python scripts.
