A virus that can spread via Wi-Fi networks has been created by researchers in Liverpool, which could put laptop users at risk.
According to BBC News, the virus is able to travel from network to network finding weaknesses in densely populated areas with lots of Wi-Fi connections.
Once in control of such an access point, it leaves computers on the network extremely vulnerable.
The virus – known as Chameleon – seeks out access points that have not had the admin password changed. This is different to the one used to log onto the network itself and is consequently often left unchanged from its default setting.
Lead researcher Alan Marshall, professor of communication networks at the University of Liverpool, said they were working on software to prevent these attacks being a possibility.
“Rather than rely on people to use strong passwords, you want to integrate intrusion detection systems to the access points.”
Chameleon can automatically find other vulnerable access points and take them over as and when they are discovered, once it is installed on one network.
