devices are not very secure. They often store the network key information in plain text without encryption or password protection. Simple AT commands can often be used to retrieve this information if the device is physically accessible. All Zigbee devices in the network have access to the encryption keys so that packets can be encoded and decoded. As a result, an attacker only needs to find the weak link in the network and exploit it to gain access to the key information. Zigbee devices are…
