Chevy Corvette is latest car breached by hackers

UPDATE: This story has been updated with comment from General Motors. In the latest car-hacking exploit in a summer full of them, researchers from the University of California-San Diego say they've found a way to manipulate braking in a 2013 Chevrolet Corvette. The vulnerabilities may not be limited to that model. Cyber-security researchers breached the car's security systems via a device they had plugged into the Corvette's OBD-II port, and through that connection, they sent messages that could turn windshield wipers on and off and tamper with the brakes as the car drove at low speeds. It's the latest in a series of car hacks that involve access to critical systems obtained via the OBD-II port, where drivers can plug in devices that provide anything from diagnostic information for mechanics to driving information for insurance companies. Last November, cyber-security engineers from Argus Cyber Security remotely controlled vehicle functions in a car that had a OBD-II dongle called a Zubie installed. In January, researchers from Digital Bond Labs found security holes in an information-tracking dongle popular with more than 2 million Progressive Insurance customers. Those came before prominent hacks unveiled in recent weeks, in which researchers remotely commandeered control of a Jeep Cherokee and, separately, showcased problems with GM's OnStar infotainment system. Regarding the dongles that plug into the OBD-II ports, Stefan Savage, a Cal-San Diego professor involved in the research, tells WIRED that, "we acquired some of these things, reverse-engineered them, and along the way, found that they had a whole bunch of security deficiencies." Savage and others unveiled the latest study at the Usenix security conference Tuesday. In a video of their exploit entitled "Fast and Vulnerable," they show how they sent SMS messages from a smartphone to the dongle plugged into the car's OBD-II port. From there, their messages accessed the CAN bus, a network on the car that connects individual electronic control units, which control dozens of vehicle functions. As they send the commands to brake the car, the driver of the Corvette notes "the pedal doesn't react to any pressure." General Motors issued a written response Wednesday, warning drivers to be careful with third-party devices they plug into their OBD-II ports.

Buick Encore, Chevy Trax earn Top Safety Pick from IIHS [w/video]

The Buick Encore has been a massive sales success practically from the moment it debuted, and Buick recently decided to increase production to keep up with demand for the premium compact crossover. The Insurance Institute for Highway Safety recently put one to the test again, and the Encore earned a Top Safety Pick award. It's the first model from the brand to score the nod since 2013, according to the IIHS, and the rating also carries over to the 2015 Chevrolet Trax. The 2015 Encore scored a Good rating in all of the IIHS' evaluations, including the 40-mile-per-hour, small overlap front crash test. That was a big improvement over the previous model the institute tested, which scored a Poor result in the overlap test. In the first test, about 13 inches of the lower door hinge pillar came into the passenger compartment, and the steering wheel airbag moved too far to protect the dummy's head. Improvements for the latest model year showed six inches of intrusion this time, and the airbags caught the dummy's head well. The dummy's sensors also indicated a low risk of injury. The two CUVs missed out on the full Top Safety Pick+ because the IIHS scored the Encore as only having a basic front crash prevention system, and there was no such equipment for the Trax. To earn the highest mark, models need at least an advanced rating by the institute for this technology. Buick Encore, Chevrolet Trax earn 2015 TOP SAFETY PICK award ARLINGTON, Va. - A small SUV is the first vehicle from the Buick brand to qualify for a TOP SAFETY PICK award from the Insurance Institute for Highway Safety since 2013. The Buick Encore's newly introduced, lower-priced twin, the Chevrolet Trax, also qualifies for the honor. The Encore's award follows improvements to the SUV's structure for better small overlap front protection. The 2015 model earns a good rating in the small overlap test. In contrast, the 2013-14 Encore rated poor in the test. The driver's space was seriously compromised with intrusion measuring as much as 13 inches at the lower door hinge pillar. The dummy's head barely contacted the front airbag before sliding off the left side, as the steering column moved to the right. The side curtain airbag deployed too late and didn't have sufficient forward coverage to protect the head. In the latest test, the driver space was maintained reasonably well, with maximum intrusion of 6 inches at the door hinge pillar and instrument panel. The dummy's movement was well-controlled.
