WPScan actively sends 802.11 probe requests to access points that advertise WPS support. It then parses out the WPS Information Element in the resulting probe response and displays the results. This is a very useful fingerprinting tool since nearly all new routers have WPS enabled by default, and most vendors will actually put the exact make, model, and version of the router in the probe response!

WPSpy is a tool to simply monitor and report changes in the WPS status of and access point. This is particularly useful if you are running some of our described attacks that leverage WPS to gain access to the WLAN.
