virus that can spread via Wi-Fi

The first trojan horse that spreads sort of a real mobile contagion has been created by researchers at the University of Liverpool's faculty of technology, physical science and engineering. Chameleon will unfold through densely inhabited areas just like the cold, the researchers claim, by hopping from network to network via access points, spreading quickly among st homes and businesses.

If that weren't unhealthy enough, the virus will avoid detection and determine weak wireless access points —those who square measure least protected by cryptography and passwords.

"Wi-Fi connections square measure more and more a target for pc hackers due to well-documented security vulnerabilities, that build it tough to discover and defend against a virulent disease," same Alan Marshall,academician of Network Security. "It was assumed, however, that it wasn't doable to develop a virulent disease that would attack Wi-Fi networks; however we have a tendency to incontestable that this will be doable which it can unfold quickly. we have a tendency to square measure currently ready to use the information generated from this study to develop a replacement technique to spot once AN attack is probably going."

The team simulated AN attack on capital of Northern Ireland and London in an exceedingly laboratory setting,and located that Chameleon behaved like AN mobile virus, traveling across Wi-Fi networks via access points. it absolutely was ready to stay hidden as a result of current antivirus programs hunt for viruses on the web and in computers, and Chameleon stayed on the Wi-Fi network, moving past protected access points to seek out those who weren't password-protected, like public Wi-Fi access points at airports and low retailers.

"When Chameleon attacked AN AP it did not have an effect on however it worked, however was ready to collect and report the credentials of all alternative Wi-Fi users who connected thereto,

 The virus then wanted out alternative Wi-Fi APs that it might connect with and infect."

The good news is that the virus was effectively blocked by secure networks, which may be came upon pretty simply. protective yourself whereas exploitation public Wi-Fi could be a very little trickier, however it may be done.
