A zero-day flaw found in Samsung FindMyMobile web service allows an attacker to cause denial of service on target's device. NIST (National Institute Of Standards And Technology) wrote " The Remote Controls feature on Samsung mobile devices does not validate the source of lock-code data received over a network, which makes it easier for remote attackers to cause a denial of service (screen locking with an arbitrary code) by triggering unexpected Find My Mobile network traffic."
