OverTheWire

OverTheWire is a wargame website that provides a series of challenges to learn about computers and security.

Bandit

The Bandit wargame was quite fun. Most challenges needed at most help from google search.

You get to learn a lot of neat unix commands, and how to use them together. Think unzip, ssl, netcat, uniq.

Leviathan

There’s a tool to ssh with password: sshpass -p 'my-password' ssh -p 2223 leviathan3@leviathan.labs.overthewire.org credits.

This means the passwords will always be in your shell history (glory to atuin)!

I found Leviathan quite challenging. Here are some hints:

leviathan0

There’s a hidden file

leviathan1

ltrace command

leviathan2

user input sanitation, think (;)
