Bandit 10 Over The Wire

 Lessons Learned

use base64 -d to decode base64 encoded data

Logging in

On a kali vm/ linux machine
Type:

ssh bandit10@bandit.labs.overthewire.org -p 2220 
truKLdjsbJ5g7yyJ2X2R0o3a5HQJFuLk

Completing The Challenge

The Goal:

The password for the next level is stored in the file data.txt, which contains base64 encoded data

The Solution:

bandit10@bandit:~$ cat data.txt
VGhlIHBhc3N3b3JkIGlzIElGdWt3S0dzRlc4TU9xM0lSRnFyeEUxaHhUTkViVVBSCg==
bandit10@bandit:~$ man base64
bandit10@bandit:~$ base64 -d data.txt
The password is IFukwKGsFW8MOq3IRFqrxE1hxTNEbUPR
bas64 is an encoding type, you can sometimes spot it in files when a string ends at = or ==

Bandit 20 Over The Wire

Lessons Learned using nc to create a steady connection, also on background and foreground processes Logging in On a kali vm/ linux machine Type: ssh bandit20@bandit.labs.overthewire.org -p 2220 GbKksEFF4yrVs6il55v6gwY5aVje5f0j Completing The Challenge The Goal: There is a setuid binary in the homedirectory that does the following: it makes a connection to localhost on the port you specify as a commandline argument. It then reads a line of text from the connection and compares it to the password in the previous level (bandit20). If the password is correct, it will transmit the password for the next level (bandit21). The Solution: bandit20@bandit:~$ nc -l -p 2000 ^Z [1]+  Stopped                 nc -l -p 2000 bandit20@bandit:~$ ./suconnect 2000 ^Z [2]+  Stopped                 ./suconnect 2000 bandit20@bandit:~$ fg 1 nc -l -p 2000 GbKksEFF4yrVs6il55v6gwY5aVje5f0j ^Z [1]+  Stopped                 nc -l -p 2000 bandit20@bandit:~$ fg 2 ./suconnect 2000 Read: GbKksEFF4yrVs6il55v6gwY5aVje5f0j
