Z-wave pairing flaw could leave smart homes at risk

If your home’s smart lock uses the Z-Wave protocol, hackers may be able to remotely unlock according to a new pairing flaw discovered by researchers at the UK firm Pen Test Partners.

The researchers found that Z-Wave, which is used by many smart home devices to communicate with one another, is vulnerable to an attack that forces the current secure pairing method, S2, to be downgraded to SO, an earlier version that contains known weaknesses.
