OverTheWire Solutions

Level 0

The goal of this level is for you to log into the game using SSH. The host to which you need to connect is bandit.labs.overthewire.org, on port 2220. The username is bandit0 and the password is bandit0. Once logged in, go to the Level 1 page to find out how to beat Level 1.

ssh [email protected] -p 2220
Password: bandit0

Level 0 - Level 1

The password for the next level is stored in a file called readme located in the home directory. Use this password to log into bandit1 using SSH. Whenever you find a password for a level, use SSH (on port 2220) to log into that level and continue the game.

ssh [email protected] -p 2220
Password: truKLdjsbJ5g7yyJ2X2R0o3a5HQJFuLk

Level 11 - Level 12

ssh [email protected] -p 2220
Password: IFukwKGsFW8MOq3IRFqrxE1hxTNEbUPR

Level 12 - Level 13

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!)

ssh [email protected] -p 2220
Password: 5Te8Y4drgCRfCx8ugdwuEX8KFC6k2EUu

Level 13 - Level 14

The password for the next level is stored in /etc/bandit_pass/bandit14 and can only be read by user bandit14. For this level, you don’t get the next password, but you get a private SSH key that can be used to log into the next level. Note: localhost is a hostname that refers to the machine you are working on

ssh [email protected] -p 2220
Password: 8ZjyCRiBWFYkneahHwxCv3wb2a1ORpYL

Level 14 - Level 15

The password for the next level can be retrieved by submitting the password of the current level to port 30000 on localhost.

ssh [email protected] -p 2220
Password: 4wcYUJFw0k0XLShlDzztnTBHiqxU3b3e

Level 15 - Level 16

The password for the next level can be retrieved by submitting the password of the current level to port 30001 on localhost using SSL encryption.

Helpful note: Getting “HEARTBEATING” and “Read R BLOCK”? Use -ign_eof and read the “CONNECTED COMMANDS” section in the manpage. Next to ‘R’ and ‘Q’, the ‘B’ command also works in this version of that command

ssh [email protected] -p 2220
Password: BfMYroe26WYalil77FoDi9qh59eK5xNr

Level 16 - Level 17

The credentials for the next level can be retrieved by submitting the password of the current level to a port on localhost in the range 31000 to 32000. First find out which of these ports have a server listening on them. Then find out which of those speak SSL and which don’t. There is only 1 server that will give the next credentials, the others will simply send back to you whatever you send to it.

ssh [email protected] -p 2220
Password: cluFn7wTiGryunymYOu4RcffSxQluehd

Level 17 - Level 18

There are 2 files in the homedirectory: passwords.old and passwords.new. The password for the next level is in passwords.new and is the only line that has been changed between passwords.old and passwords.new

NOTE: if you have solved this level and see ‘Byebye!’ when trying to log into bandit18, this is related to the next level, bandit19.

ssh [email protected] -p 2220
Password: xLYVMN9WE5zQ5vHacb0sZEVqbrp7nBTn

Level 18 - Level 19

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.

ssh [email protected] -p 2220
Password: kfBf3eYk5BPBRzwjqutbbfE887SVc5Yd

Level 19 - Level 20

To gain access to the next level, you should use the setuid binary in the homedirectory. Execute it without arguments to find out how to use it. The password for this level can be found in the usual place (/etc/bandit_pass), after you have used the setuid binary.

ssh [email protected] -p 2220
Password: IueksS7Ubh8G3DCwVzrTd8rAVOwq3M5x

Level 20 - Level 21

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).

ssh [email protected] -p 2220
Password: GbKksEFF4yrVs6il55v6gwY5aVje5f0j

Level 21 - Level 22

A program is running automatically at regular intervals from cron, the time-based job scheduler. Look in /etc/cron.d/ for the configuration and see what command is being executed.

Password: jc1udXuA1tiHqjIsL8yaapX5XIAI6i0n

Level 24 - Level 25

A daemon is listening on port 30002 and will give you the password for bandit25 if given the password for bandit24 and a secret numeric 4-digit pincode. There is no way to retrieve the pincode except by going through all of the 10000 combinations, called brute-forcing.

Level 0

Natas teaches the basics of serverside web security.

Each level of natas consists of its own website located at http://natasX.natas.labs.overthewire.org, where X is the level number. There is no SSH login. To access a level, enter the username for that level (e.g. natas0 for level 0) and its password.

Each level has access to the password of the next level. Your job is to somehow obtain that next password and level up. All passwords are also stored in /etc/natas_webpass/. E.g. the password for natas5 is stored in the file /etc/natas_webpass/natas5 and only readable by natas4 and natas5.
