The wider the coverage of wireless network or WiFi, the more vulnerable it is subject to attack. And the attack could be wide spread over a city. Yeah, it’s no joke, the statement here doesn’t come out from the mouths of those paranoids. It’s from a paper written by a team of researchers at Indiana University.
I absolutely agree with it. Wireless routers are not as secure as the wired counterparts, although the development of WPA encryption has increased (theoretical) wireless security significantly. As the density and scale of wireless coverage has expanded, however, the chance that a router-focused viral attack could cause significant damage has increased. How many of those out there leave their wireless routers’ default passwords unchanged. And how many of the wireless routers are easily to crack with their short passwords. All these are simply vulnerable to the attack of malware.
The research team has carried out simulation on how quickly an infection would spread across the various wireless networks and what general steps shall be taken to prevent or reduce the attack. The result of the simulation shows that non-encrypted wireless routers are the fastest to be conquered by malware, followed by the second is WEP-encrypted routers - although comparatively slower but not immune to malware attack. Only WPA-enabled wireless routers configured with strong password are considered impregnable.
