OverTheWire Bandit Level 5 Walkthrough

Today we're doing a walkthrough for level 5 of the Bandit CTF wargame hosted on OverTheWire.org.  First, let's take a look at the objectives for the level:

https://overthewire.org/wargames/bandit/bandit6.html


So the Flag will be located in a file within the inhere directory and has the following qualities:

human readable
1033 bytes in size
not executable

Let's SSH into the server to start the level:

ssh bandit5@bandit.labs.overthewire.org -p 2220


Now let's look for the inhere directory.  In the previous level, it was a hidden directory, so we'll use ls -a to locate it.

pwd
ls -a


Now we take a look in the inhere directory:

cd inhere
ls -a


Quite a few files.  let's use the find command to locate the file we're looking for.  We'll use the -size switch to locate files that fit the size requirement of 1033 bytes.  When using the -size switch, bytes are indicated by the c suffix.

find ./ -size 1033c


Only one file matches our size criteria, so we'll cat out that file and we should get our Flag.

cat ./maybehere07/.file2


Summary

Bandit5 requires us to look for a file that matches criteria, so we use the find command to look for the file that matches the criteria, then access it to receive the level's flag.

Finish
