Over the Wire - Bandit Wargame Solutions Level 1-6

Wargame in hacking is a security challenge in which one must exploit a vulnerability in a system or application or gain access to a computer system. These wargames are intended to increase your knowledge about security measures and counter measures.

One of the most famous wargaming site is called overthewire.org. In this site "Bandit" is the recommended game to start if you are new to site. In this game, password for the next level is hidden in the previous level. You goal is to find that hidden password.

You should already be familiar with basic Linux commands before attempting this wargame. It doesn't matter you don't know much more on Linux, by doing this wargame you can gain fair knowledge on Linux commands. And most importantly you have to use a bit of your own intuition to figure out how to make it from one level to the next.



If you are using Linux/Unix platform;

  • Open a Terminal.
  • type ssh levelNumber@bandit.labs.overthewire.org -p 2220 and then type the password you have found                                                       Eg: bandit0@bandit.labs.overthewire.org -p 2220
  • Once you have found the password for the next level use 'exit' command to disconnect connection to server.
  • Reconnect to the server to go the next level.



If you are using Windows;



  • Click Open.
  • Once terminal is opened type username and password.
  • After you have found the password for the next level restart the Putty and go the next level.


I'm using Putty to play the game. I digress, use my posted solutions to learn and understand the levels or compare with your own solutions. Enjoy!

Level 0:

Type username as 'bandit0' and password as 'bandit0'.
Then find the password for the next level by typing below commands.

bandit0@bandit:~$ ls
readme
bandit0@bandit:~$ cat readme
boJ9jbbUNNfktd78OOpsqOltutMc3MY1       <- Password for next level         
bandit0@bandit:~$

New things we learn from this level:
  • ls - lists current directory contents of files and directories.
  • cat - display the content of text files (and to combine several files to one file).


Level 0 -> Level 1
Type username as 'bandit1' and password as 'boJ9jbbUNNfktd78OOpsqOltutMc3MY1'.
Then find the password for the next level.

bandit1@bandit:~$ ls
-
bandit1@bandit:~$ cat < -

New things we learn from this level:
  • file - determines the file type of a file. It reports the file type in human readable format (e.g. ‘ASCII text’)
  • use of * - list any file starting with '-'
Level 4 -> Level 5

Introduction to Encryption

Image
What is Encryption? Encryption is like sending secret messages between parties; if someone tries to pry without the proper keys, they won't be able to understand the message. In other words, it is the process of locking up information using cryptography (Cryptography is both the practice and the study of hiding information.) Definition:  ‘ The Process of converting plain text into cipher text, something that appears to be random and meaningless ’ is called as the encryption. Process of converting cipher text back into original text is called as decryption . Terminology Original message is called as plain text/clear text.   Encrypted message is called as cipher text/encrypted text.  A Key which is a secret like a password which is used to encrypt and decrypt information.  Ciphers are the specific algorithms which are used to encrypt and decrypt data. A cipher is series of well-defined steps that can be followed as a procedure to encryp...

RESTful API

Image
RESTful APIs are application programming interfaces (API) that adhere to architectural style of REST architectural pattern and it is used to HTTP requests to GET, PUT, POST and DELETE data. RESTful API has the following features: Those are the guiding constraints which define a RESTful system. Client–server - The client handles the front end the server handles the backend and can both be replaced independently of each other. Stateless - No client data is stored on the server between requests and session state is stored on the client. Cacheable - Clients can cache response (just like browsers caching static elements of a web page) to improve performance. Uniform Interface - The key to the decoupling client from server is having a uniform interface that allows independent evolution of the application without having the application’s services, or models and actions, tightly coupled to the API layer itself. Layered System - REST APIs have different layers of their a...
