Hey,

A couple of years ago I wrote solutions for the OverTheWire Bandit wargame. Recently, while reorganizing my documentation, I revisited that material and decided to properly clean it up and restructure it into a single, coherent walkthrough. This isn’t a formal course, it’s a complete Bandit walkthrough with in-depth explanations, written to extract as much understanding as possible from each level, not just to get the flag.

For every level, I included:

• hints and spoiler warnings, so you can try before reading the solution
• intermediate reasoning when it makes sense
• links to official documentation and primary sources

The intent was to make this usable by someone starting from zero, but also detailed enough that you can finish Bandit feeling like you’ve actually milked it for all the knowledge it has to offer. Commands, patterns, and underlying UNIX concepts.

This is probably most useful if you:

• are new to CTFs or system/security basics
• want to understand what you’re doing instead of copying commands
• plan to move on to harder OverTheWire games later

And to be fair, I think that even people that are more used to working with UNIX might actually learn a thing or two from these
