CERT/CC Vulnerability Note VU#723755
Vulnerability Note VU#723755 Original Release Date: 2011-12-27 | Last Revised: 2012-05-10 The WiFi Protected Setup (WPS) PIN is susceptible to a brute force attack. A design flaw that exists in the WPS specification for the PIN authentication significantly reduces the time required to brute force the entire PIN because it allows an attacker to know when the first half of the 8 digit PIN is correct
