OverTheWire: Bandit Level 8
This is going to be a walkthrough of Level 8 of Bandit from OverTheWire Wargames.
We found the password from level 7.
Username: bandit8
Password: cvX2JJa4CFALtqS87jk27qwqGhBM9plV
This level is asking us to use pipes in order to separate information from a file.
First we SSH into the box and list all the files.
So the password is somewhere in data.txt and when we have a look at what data.txt contains, we see that it is full of possible passwords.
The information about the level tells us that the password will only appear once in the file. So we need to use commands that pull out the only unique line in data.txt.
To do this, we need to use pipes. Some information about pipes is given in the Helpful reading material if you are not too familiar with pipes.
The commands we are going to use are sort and uniq. The sort command does exactly as it sounds, sorts the file in alphabetical order. The reason we are using sort is because uniq only gets rid of duplicate files if they are next to each other.
Firstly we need to cat the file onto the screen.
Then we can use a pipe to the sort command to sort the output in alphabetical order.
Once this is done, we can then pipe it to the uniq command with a certain flag set.
And that gives us the password to the next level.
