Reaver-wps performs a brute force attack against the AP, attempting every possible combination in order to guess the AP’s 8 digit pin number. Because the WPS protocol is conducted over EAP, the registrar need only be associated with the AP and does not need any prior knowledge of the wireless encryption or configuration. Registrars may authenticate themselves to an AP at any time without any user interaction. In order to authenticate as a registrar, the registrar must prove its knowledge of the AP’s 8-digit pin number. Access points will provide authenticated registrars with their current wireless configuration (including the WPA PSK), and also accept a new configuration from the registrar. Reaver-wps targets the external registrar functionality mandated by the WiFi Protected Setup specification. It is very important that you have a supported card, otherwise you’ll be just wasting time and effort on something that just won’t do the job. A list can be found in 802.11 Recommended USB Wireless Cards for Kali Linux. You should purchase a card that supports Kali Linux including injection and monitor mode etc. Important Note: Many users try to capture with network cards that are not supported. Possibilities of cracking is a lot higher in this way.

You can make rules to only try letters and numbers to crack a completely unknown password if you know a certain Router’s default password contains only those.
If you know 4 characters in a password, it takes 3 minutes. For example: if you know 3 characters in a password, it takes 12 minutes to crack it. Using Hashcat is an good option as if you can guess 1 or 2 characters in a password, it only takes few minutes. Hashcat can crack Wifi WPA/WPA2 passwords and you can also use it to crack MD5, phpBB, MySQL and SHA1 passwords. This is an alternative to using dictionary attack where dictionary can contain only certain amount of words but a brute-force attack will allow you to test every possible combinations of given charsets. The benefit of using Hashcat is, you can create your own rule to match a pattern and do a Brute-force attack.
Those who would like to try more ways of cracking Wifi WPA WPA2 passwords, you can also use HashCat or cudaHashcat or oclHashcat to crack your unknown Wifi WPA WPA2 passwords. using pyrit cowpatty and WiFite combination attack with dictionary.The whole process takes less than 10 minutes. Readers, note that I’ve since written another post where I could crack a password in 14.21 seconds. While Reaver-wps does not support reconfiguring the AP, this can be accomplished with wpa_supplicant once the WPS pin is known. This post outlines the steps and command that helps cracking Wifi WPA/WPA2 passwords using Reaver-WPS. Once the WPS pin is found, the WPA PSK can be recovered and alternately the AP’s wireless settings can be reconfigured. Reaver-wps performs a brute force attack against an access point’s WiFi Protected Setup pin number.
