Scenario:

[Olivia]

Codebook attack is very easy to perform and can be done easily on Linux. If you do not have the password file, you need to obtain it from the target website manually or through any other means. Then, you need to convert the password hash into plain text using John The Ripper software utility.

• John The Ripper software utility is a very important program if you are going to perform a password-cracking test. It is a very efficient password cracker and can be easily used to recover passwords of any website.
• Once you have the plain text password of the target, you can search it in the codebook file and find the exact password. If your password is found in the codebook file, it means that your password is in use. It could be guessed using any other techniques and techniques.
• But if your password is not found in the codebook file, then there are chances that it is a totally new one and has never been seen before by hackers.
  This type of homemade codebook is called a “newbie codebook” or “noob codebook”.
• These codebooks can be created with the help of a very easy-to-use tool, which is available online. It completely works on Linux and has its own database of more than 50000 most common passwords.

Conclusion:
A codebook attack is more efficient and better than dictionary attack because it recovers passwords that are hard to guess using other attacks. It is also better than rainbow tables because it recovers the exact password rather than the “almost matching” one. There are many free codebooks available on the internet that anyone can download for free and start using to recover their own password or someone else’s too.
