The Smart Scale PW 5653 BT is made by China-based AEG and features Bluetooth for analyzing weight, body fat, and other data points. AEG is a premium brand for Chinese consumers introduced by home appliances firm Electrolux Group and Midea Group as a joint venture. Researchers have advised AEG to issue a patch that fixes clients smart scales to prevent malicious users from damaging the hardware, but have not heard back. The most severe of the flaws discovered in the IoT device is a Denial of Service vulnerability, which allows attackers to trigger a special request via Bluetooth that crashes the smart scale.
