Challenge Overview

We followed a breadcrumb trail across multiple platforms to find Xavier's resignation letter.

Attack Chain

1. GitHub - Found repository with suspicious commit history
2. Spotify - Discovered Spotify profile link in deleted commit
3. Reddit - Found reference to blogger
4. Blogspot - Located blog (now empty)
5. Wayback Machine - Found archived version with resignation letter
6. Base64 - Decoded the hidden message

The blog appeared empty, but using the Wayback Machine, we found a deleted resignation letter. At the bottom was a Base64 string that decoded to the flag.
