University of Liverpool scientists have discovered they can produce a Wi-Fi virus that can move through dense wireless (unprotected) networks and infect multiple systems. The team designed a virus called Chameleon and found that it was able to spread rapidly from one network to another. The virus was also able to identify weak networks, those without encryption or passwords. The scientists found that Chameleon had human airborne virus qualities in its ability to infect one wireless network after another, much like the flu bug in humans. The closer the networks are to each the other the more likely the virus will spread through them.
