The file doesn't just sit on your desktop; it pulses. In the logic of the "Tokyo Ghoul" room on TryHackMe , it is a digital cage for a secret that doesn't want to be found.
But it was the image, ghoul.jpg , that held the true horror. When Elias used a steganography tool to peek behind the pixels, he didn't find a password. He found a GPS coordinate and a timestamp for Tuesday, April 28, 2026 .
The screen didn't spit out files. It asked for a passphrase. Elias tried the usual suspects: keneki , touka , anteiku . Nothing. He looked closer at the metadata he'd scraped from the GitHub project where the source code for the server's authentication module lived. Tucked inside a comment in a RADIUS client library was a string of base64: SGVscCBtZSBvdXQ= . "Help me out," Elias whispered, typing the decoded text.
It was a classic TryHackMe scripting challenge . Elias fired up a Python script, looping the decoding function until the digital noise cleared. At the 50th iteration, the terminal flashed a single line: FLAG{Welcome_to_the_Anteiku_Management_System}
Should Elias or try to hack the assignee profile?
This file has been base64 encoded 50 times, it read. Write a script to retrieve the flag.
