The wi-fi connections of businesses and homes around the world are at risk, according to researchers who have revealed a major flaw dubbed Krack.

It concerns an authentication system which is widely used to secure wireless connections.

Experts said it could leave “the majority” of connections at risk until they are patched.

The researchers added the attack method was “exceptionally devastating” for Android 6.0.

The US Computer Emergency Readiness Team (Cert) has issued a warning on the flaw.

“US-Cert has become aware of several key management vulnerabilities in the four-way handshake of wi-fi protected access II (WPA2) security protocol,” it said.
