Introduction Details about the challenges may be found at https://overthewire.org/wargames/bandit/. The game is played over SSH over port 2220 so firewalls may need to be adjusted to allow outbound traffic to connect to the game. The game has 34 levels. The levels are chained, so that to get to the next level you need to complete/finish/beat the previous level.
WARNING: These are my own notes and contain actual flags.
Bandit Level 0 Level Goal The goal of this level is for you to log into the game using SSH.

The reason presented was that zip did not provide the desired level of confidentiality and integrity. This comment got me thinking as I had thought that zip used AES for encryption, so now I am awake at 0100hrs in the morning and curious to understand the encryption used in zip.
