Hello, devils! Today I'm going to introduce you to a network security feature of Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2) networks named Wi-Fi Protected Setup (WPS).The WPS was released as an additional security measure for WPA/WPA2 routers. WPA and WPA2 were security protocols which were far more secure than the former protocol, Wired Equivalent Privacy (WEP). It was found that the Pre-Shared Key (PSK) or simply, password of WEP could be cracked very easily. Therefore, in 2003, WPA/WPA2 Wi-Fi security protocols were released. The WPS has a PIN feature to connect network devies to the Access Points. Later, it was found to have a major security bug which allowed hackers to crack the PIN and with the PIN, attackers could have access to the WPA-PSK/WPA2-PSK (Password). In this post, I'm going to teach you how to crack WPS of a router.
