What has Science done? Wi-Fi-travelling virus is possible, say scientists

See and know about the future threat s

A. Hamilton

Researchers at the University of Liverpool have shown that WiFi networks can be infected with viruses much like airborne illnesses spread between humans.

As reported by ScienceBlog, the team designed and carried out an attack by a virus named “Chameleon”. The virus did not just spread quickly between homes and businesses, but avoided detection and targeted weakened points specifically.

The attack was a simulated one on Belfast and London, and revealed that the Chameleon virus behaved similarly to a natural virus like the common cold. It travelled through WiFi networks via access points (APs) and infected hosts fastest in densely populated areas, where multiple APs are clustered together.

Silent but dangerous

Since Chameleon is only present in the WiFi network, virus detection systems failed to pick it up at all. If the virus discovered an AP that was encrypted and password protected, it moved on to another that wasn’t…
