Most wireless networks are secured by WPA or WPA2 encryption, which is able to be cracked by capturing a network handshake and using your computer's CPU to brute-force the password. As password lists get bigger, CPU and GPU performance becomes more important as the rate at which passwords can be attempted is sped up.īrute-Forcing WPA, SSH, FTP & Other Passwords And finally, the password must be present in the list in order for the attack to succeed. Third, you need a list of passwords to automatically try very quickly. Second, you need to be able to determine the difference between a password success and failure. Many security protocols are vulnerable to brute-forcing attacks, which at its core relies on a few key principals.įirst, you must be allowed to try different passwords many times very quickly. Password cracking is a long-established art, relying on a combination of brute-force processing power and the ability to refine your list down to likely options based on what you know about a target. Using the Mentalist, we can generate millions of likely passwords based on details about the target. The science of brute-forcing goes beyond using these default lists, allowing us to be more efficient by making customized wordlists. Beginners learning brute-forcing attacks against WPA handshakes are often let down by the limitations of default wordlists like RockYou based on stolen passwords.
