Denis Andzakovic’s motorcycle enables him to “terrorize his neighbors” by scanning for Wi-Fi access points as it passes them. The bike is fitted 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, and it is able to detect wireless access points and plot them on Google Maps. It can also wreak havoc by kicking users off wifi networks on the fly by using what’s called “deauthentication packets.” Andzakovic has found that 26.91 percent of wireless access points he surveyed on the Australian Gold Coast had no wifi security at all, and a further 6.13 percent used a form of WEP encryption, which has been found to be easily cracked. The rest used a form of WPA security, which is generally considered fairly secure if a complex password is used. http://alrt.co/1a5NUtk
Takeaway: A strong wifi password with a WPA2 encryption is essential to prevent unauthorized free-riders hopping on and booting you off your own network.
