There's something unusual about the motorcycle Denis Andzakovic likes to ride.

In addition to being able to transport Andzakovic, 22, from A to B, it can also allow him and others to "terrorise their neighbours" by scanning for Wi-Fi access points as it passes them.

Looking into the head mounted display.

Kitted out with a miniature Raspberry Pi computer for a heads-up display (HUD) integrated in an external helmet, two Mikrotik routers, wireless sniffing and attack tools, GPS and a netbook, the motorcycle is able to detect wireless access points and plot them on Google Maps.

It can also wreak havoc by kicking users off Wi-Fi networks on the fly by sending out what's called "deauthentication packets". When Andzakovic gets home he can then attempt to crack the security of protected access points using data collected while passing them.
