So progression of these levels is going really well, and I am already on bandit level 7. If you haven’t had a chance to read my OverTheWire Bandit Write Up – Level 6 write up give it a quick read then head back over here. Enjoy that? Hopefully you did and will enjoy this one too.

Level 7

The hints that I’ve got for this level is that the password is contained in a file named data.txt and the password if adjust to the word millionth. Reading these hints made my think that this file may contain a lot of lines. This potentially won’t allow for me to just scroll through and find it.

Let’s Start Hacking Then

As usual I start by spinning up a fresh terminal to start the SSH connection to the system.

ssh bandit7@bandit.labs.overthewire.org -p 2220

I tried the password from the last level, and it worked. So I’m all good. I’m sat in the home directory of the bandit level 7 user so I run the normal command ls and check what I have to hand. Inside this directory is the data.txt file, I’m glad I don’t have to try and find it this time. So I open the file up to have a look.

cat ./data.txt

The file opens and is filled with lines and lines of different password styled lines. Each of these starting with a different word. I know from the hint that I need the line that starts with millionth, I can ever scroll through all of the lines until I find it or look for a different way of finding it. Knowing that I can use the grep command to search for content from within a file.

grep -w ./data.txt -e "millionth"

I am now presented with a single line, with the word millionth, this looks like I have the password for Level 8.

Level 7 Complete

I have hidden the password here, if you are playing along don’t peek! Please! It’s more fun getting it yourself.
