Hence, it can be deduced that WPS protocol which was actually designed to make routers more secure has, in fact, left them even more vulnerable to hacking attacks.Īs they say, prevention is better than cure, the only way out to be thoroughly ascertained that your wireless network is not compromised is to buy a router that has no WPS provision, either through a physical switch or through its admin interface. This attack has the potential to cause wide-scale damage since the attacking device can just be left in the vicinity of the target network and controlled remotely. These stolen MAC addresses can be spoofed on the attacking device’s network device so as to trick the router into considering it as a valid device. MAC filtering does not help to prevent the attack since a network scanner can gulp the MAC addresses of devices already connected to the victim router.

In a few minutes or hours, the command would cough up the SSID and Password (WPA PSK) of the attacked router. The software application has been tested against a vast variety of WPS and access point implementations. The router might lock up in between requests but the command is intuitive enough to pick up right from the place where it gets stuck through continuous polling of the access point. But the above two (-i and -b) are enough to do the trick for the majority of routers. Some of these can be used to tweak the command to wait for response signals for slow routers or to clear out failed attempts.
Sudo reaver -i wlan0 -b 00:0a:0b:0c:0d:0eĪ number of other options or settings are available as well for reaver command which can be seen in its help page. Next, be sure to disconnect from all other WiFi networks. Before mounting any attack, the wireless adapter of the attacking device (a computer running Linux) also needs to be put into monitor mode with the use of the following commands: Here sudo grants root access to the user. This command will show you all the routers in the vicinity, their MAC addresses along with loads of other useful information. To be able to hack, a WiFi scanning application like Linux utility “airodump-ng” helps the user to know the MAC address of any router while a few routers like the one shown above have them printed on the physical device itself. There is neither a need to remember a password nor to reach for admin settings in the router’s interface. In WPS mode, this PIN can be used by a connecting device to retrieve the router’s configuration settings directly without any user intervention. An open-source version of an attack tool called Reaver has been developed by Craig Heffner of Tactical Network Solutions to tap into this specific security hole in WPS-enabled routers.
