Z-Wave Downgrade Attack Left Over 100 Million IoT Devices Open to Hackers

The issue resides in the implementation of Z-Wave protocol—a wireless, radio frequency (RF) based communications technology that is primarily being used by home automation devices to communicate with each other.

Z-Wave protocol has been designed to offer an easy process to set up pairing and remotely control appliances—such as lighting control, security systems, thermostats, windows, locks, swimming pools and garage door openers—over a distance of up to 100 meters (330 feet).
