Advent of Cyber 2025 | Day 02 | Summary:

In this room we join the TBFC red team and launch a Python server that hosts a fake login page to capture credentials. Using SET (Social-Engineer Toolkit) we craft a spoofed email pointing to our fake login page.

Advent of Cyber 2025 | Day 01 + Bonus Challenge | Summary:

We start out by investigating a compromised server, collect some hidden flags and uncover some secrets. All this, by using nothing but basic Linux CLI commands.

For the bonus part, we first solve three riddles, then concatenate the fragments and decrypt a note. Once we fixed a glitching server, we capture the ciphertext, decode it, then decrypt the secret archive directory which was left behind. Extracting the archive enables us to retrieve the final side-quest flag.
