SAN FRANCISCO - A serious vulnerability in Wi-Fi chips has been discovered that affects billions of devices worldwide, according to researchers.

According to ESET, "[it] found KrØØk to be one of the possible causes behind the 'reinstallation' of an all-zero encryption key, observed in tests for KRACK attacks.

Listening to a smart home hub can retrieve any information sent between it and satellite devices such as a connected doorbell, smart thermostat or smart lights, or laptops, computers and mobile devices.

Fixes have been released by major manufacturers, according to ESET, and users will need to update their devices in order to ensure that communications from their Wi-Fi devices can't be easily hacked and eavesdropped upon.

The totaling of more than a billion devices affected is "a conservative estimate," according to ESET's paper, because KrØØk is likely not limited to just the devices the company tested.
