The Sakura Room on TryHackMe is an OSINT (Open Source Intelligence) challenge created by OSINT Dojo. The goal was to track down a fictional attacker by analyzing publicly available data across multiple platforms. Throughout the challenge, I used real-world OSINT methodologies to uncover a digital trail left behind.
