The Argus research group succeeded in remotely taking over safety-critical vehicle systems via a Bosch Drivelog Connector dongle installed in the vehicle. A vulnerability found in the authentication process between the dongle and the Drivelog Connect smartphone application enabled Argus researchers to uncover the security code within minutes and communicate with the dongle from a standard Bluetooth device, such as a smartphone or laptop.

After gaining access to the communications channel, Argus researchers were able to duplicate the message command structure and inject malicious messages into the in-vehicle network. Effectively bypassing the secure message filter that was designed to allow only specific messages, these vulnerabilities enabled the Argus research group to take control of a moving car, demonstrated through remotely stopping the engine.

As soon as Argus found cyber security vulnerabilities in the Bosch Drivelog Connector dongle, Bosch was duly informed. The level of attention the matter received from Bosch top management was significant and their Product Security Incident Response Team worked quickly to immediately address the issues across their security and development divisions. Additional work is also being done to further limit the possibility to send unwanted CAN messages and will be rolled out alongside further improvements later in the year.
