Calculate the default 8-digit WPS PIN for MAC address D6:8F:2F:91:1F:B1 used during Wi-Fi Protected Setup pairing.
WPS (Wi-Fi Protected Setup) was designed to make it easy to join devices to a wireless network: you press a button on the router, the router and the device exchange a short code, and the device joins the network. That convenience is also where the weakness lies. While the WPS PIN is enabled, an attacker nearby can brute-force the eight-digit code and take over your network access without ever knowing the Wi-Fi password.
The eight-digit code is derived from the router’s MAC address, which means it can be calculated offline instead of guessed. Knowing how that code is produced is the difference between a network that takes hours to break and one that falls in minutes.
The step-by-step procedure for recovering a WPS PIN, and the tools involved, are described in the article below. That article is written for education only. How to Hack a Wi-Fi Password
