So you think you know Linux? This module explores some Linux security trickery, from the trivial to the taxing. Take it away!

If you don't know any Linux, this might be a tough place to start. pwn.college has an entire intro-to-the-commandline module here. Without that knowledge, solving these challenges is unlikely. Even with this knowledge, they might be tricky ;-)

ATTENTION: Just because this module is listed first in the module list doesn't mean that its challenges are all easier than the later modules' challenges! You don't have to do things in order: the first chals of later modules are much much simpler than the latter chals of this module!


Challenges

This one is a freebie, if your fortune allows...

HINT: Ignore the fortune binary itself. This challenge would be functionally identical if it ran any other command.

Expand your mind, and read the flag!

Can you read the unreadable file?

Can you overcome your limits?

Thing curl get.docker.com | sh is safe? Think again!
