Wi-Fi network owners could end up paying a heavy price for being lazy about passwords. Researchers in the UK have created a new virus in the lab that they say can attack weak points in Wi-Fi, moving through them like the flu.

The virus, dubbed "Chameleon," sounds like something James Bond would have to battle, but researchers at the University of Liverpool had noble reasons for creating it. A team from the university's School of Electrical Engineering, Electronics and Computer Science led by network security professor Alan Marshall wants to stay one step ahead of would-be network hijackers.
Details about Chameleon are sparse, but essentially the virus works by attacking Wi-Fi network points where a router's administrative password has not been changed, the BBC's Dave Lee reported. This password is different from the one you'd use to access the network at a friend's house or coffee shop - it's also often left unchanged.
Marshall and his team got Chameleon to automatically seek out other unprotected Wi-Fi access points in a controlled lab setting, spreading through networks like a common cold going around an elementary school. They published their findings in the EURASIP Journal on Information Security (full article).
