When Chameleon attacked an AP it didnt affect how it worked, but was able to collect and report the credentials of all other Wi-Fi users who connected to it, Marshall said.

Wi-Fi connections are increasingly a target for computer hackers because of well-documented security vulnerabilities, which make it difficult to detect and defend against a virus, said Alan Marshall, a professor of network security at the school. It was assumed, however,但丁湾百度影音 that it wasnt possible to develop a virus that could attack Wi-Fi networks; but we demonstrated that this is possible and that it can spread quickly. We are now able to use the data generated from this study to develop a new technique to identify when an attack is likely. copyright dedecms

Researchers at Englands University of Liverpool have created Chameleon, a virus that can proliferate via Wi-Fi as efficiently as the common cold infects humans.

British researchers have created a computer virus that they say is the first to spread like a real airborne contagion.

The team simulated an attack on Belst and London in a laboratory setting, and found that Chameleon behaved like an airborne virus, traveling across Wi-Fi networks via access points. It was able to remain hidden because current antivirus programs look for viruses on the Internet and in computers, and Chameleon stayed on the Wi-Fi network, moving past protected access points to find those that werent password-protected, such as public Wi-Fi access points at airports and coffee shops. copyright dedecms

The University of Liverpools research appears in the Eurasip Journal on Information Security.

Chameleon can spread through densely populated areas like the common cold, the University of Liverpool researchers claim, by hopping from network to network via access points, spreading rapidly among homes and businesses. If as that wasnt bad enough, the virus can avoid detection and identify weak wireless access points -- those that are least protected by encryption and passwords. copyright dedecms

The good news is that the virus was effectively blocked by secure networks, which can be set up pretty easily. Protecting yourself while using public Wi-Fi is a little trickier, but it can be done.
