Some of the supported features as described by the manufacturer are (see [1]): " Wireless alarm system with emergency call and handsfree function Integrated GSM (Dual Band) phone dialling with message function Handsfree/Room monitoring functions on the base unit Up to 10 phone numbers can be programmed Accoustic alarm via built-in sirene Programme the forwarding of alarms to external telephones (e.g. mobile phones) Alarm per Telephone with message function Individual message for each sensor, max. 10 seconds long Power failure backup in the base unit Can be upgraded to support up to max. 32 sensors Easy integration of the optional sensors via Plug & Play method " Due to an insecure implementation of the used 868 MHz radio communication, the wireless alarm system Olympia Protect 9061 is vulnerable to replay attacks. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Vulnerability Details: SySS GmbH found out that the radio communication protocol used by the Olympia Protect 9061 wireless alarm system and its remote control is not protected against replay attacks. Therefore, an attacker can record the radio signal of a wireless remote control, for example using a software-defined radio, when the alarm system is disarmed by its owner, and play it back at a later time in order to disable the alarm system at will. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Proof of Concept (PoC): SySS GmbH could successfully perform a replay attack as described in the previous section using a software-defined radio and disarm a Olympia Protect 9061 wireless alarm system in an unauthorized way. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Solution: The reported security issue was fixed by the manufacturer in a new product version.
