Misc challenge that resolves around reconstructing a QR Code. This is an intentionally easy challenge as it is solvable with a little scripting knowledge.

Theme

The TAs creating the endterm exam have suffered in the past from leaked drafts. To protect themselves against further leaks they invented the mega obfuscated secure advanced information communication (mosaic) system. The mosaic system encodes emails as QR-Codes and then applies the ultra secure protection algorithm. We found a QR-Code that was not disposed properly in a waste bin. Can you decipher the email? Hint: The mosaic algorithm adds decoy fake data to the QR-Code. It is mega secure after all!
