Cracking WPA/WPA2 with Reaver
The WiFi Protected Setup (WPS) protocol is vulnerable to a brute force attack that allows an attacker to recover an access point’s WPS pin, and subsequently the WPA/WPA2 passphrase, in just a matter of hours, using the open source tool called Reaver. Think your 32 character alpha-numeric password is uncrackable? If your wireless router is using WPS then your router may be spit back your password in plain-text to the attacker in less than 10 hrs. WPS allows users to enter an 8 digit PIN to connect to a secured network without having to enter a passphrase. When a user supplies the correct PIN the access point essentially gives the user the WPA/WPA2 PSK that is needed to connect to the network. Reaver will determine an access point’s PIN and then extract the PSK and give it to the attacker. When we tested Reaver in our labs we were able to recovery the WPA password in 1.5hrs and the longest run was 7.5hrs
