Today we are gonna take a look at the newest tool in hacking wpa/wpa2, Reaver.
This tool bruteforces the Wi-Fi Protected Setup, which uses a PIN
containing 8 unknown digits, if you do the math (10^8) that’s around
100,000,000 possibilities. Upon discovering the PIN, Reaver replies back
the WPA / WPA 2 key.
Note that not all routers are affected by this, as the person who
configured the router might have disabled WPS. It is known however, that
the majority of routers come with WPS enabled.

Protecting yourself against this attack is simple: disable WPS. This
is done by accessing your router (usually at 192.168.1.1 at a class C
network), after login in, disable WPS.
