Device hijacking via IMEI-based identity spoofing
Published Feb 6, 2025 · Updated Feb 10, 2025
Authentication bypass in Forever KidsWatch KW50 and KW60 firmware allows physically proximate attackers to hijack and control a watch. The service uses the mutable IMEI as the device identifier and trusts a matching value to associate the watch with a mobile-app account. Exploitation requires changing the target watch's IMEI to that of an attacker-controlled unit already registered in the app; the app then grants control of the target watch.
