Drivers of Internet-connected vehicles should be alert to hackers targeting them, the Federal Bureau of Investigation warned in a public service announcement on Thursday.
“Modern motor vehicles often include new connected vehicle technologies that aim to provide benefits such as added safety features, improved fuel economy, and greater overall convenience,” the FBI said. “Aftermarket devices are also providing consumers with new features to monitor the status of their vehicles. However, with this increased connectivity, it is important that consumers and manufacturers maintain awareness of potential cybersecurity threats.”
The FBI notes that researchers have developed ways to attack vehicle engines, brakes, steering, locks, turn signals, tachometers, radios and other systems. While attacks conducted over Wi-Fi have been limited to a distance of less than 100 feet from the vehicle, hackers can work remotely by targeting a vehicle’s cellular carrier.

Some additional components that can be attacked include keyless entry systems, ignition control and diagnostic and navigation systems.
To counter the potential threat, the FBI advises consumers keep their software updated and to refrain from making modifications that haven’t been authorized by the manufacturer. Additionally, the FBI suggests, they should be wary of devices they plug into USB ports.
“There has been a significant increase in the availability of third-party devices that can be plugged directly into the diagnostic port,” the agency states. “These devices, which may be designed independent of the vehicle manufacturer, include insurance dongles and other telematics and vehicle monitoring tools. The security of these devices is important as it can provide an attacker with a means of accessing vehicle systems and driver data remotely.
“In much the same way as you would not leave your personal computer or smartphone unlocked, in an unsecure location, or with someone you don’t trust, it is important that you maintain awareness of those who may have access to your vehicle,” the bureau adds.

Fiat Chrysler issued the first vehicle recall over hacking vulnerabilities last year. The company was forced to withdraw more than 1.4 million cars after security researchers discovered a method of exploiting them remotely.
