Chris Valasek and Charlie Miller, who famously shown how a car’s system can be hacked and attacked in last year’s DefCon convention in Las Vegas, Have announced the prototype of a device that blocks penetrations. The two will make an official presentation of the device on next month’s Black Hat convention that will take place also in Las Vegas.
Miller works as a security researcher at Twitter, while Valasek is the director of vehicle security research at IOAative, a security consultancy firm.
The two showed last year how they can intervene from afar with the breaking process during driving, and Miller says that these attacks seemed serious enough that we should actually consider how to defend against them. We actually wanted to do something to help solve this problem.”
The device plugs into a OBD2 port, located usually below the dashboard, and it checks the automobile’s data patterns. After it had run its check it can switch to detection mode – monitor any anomalies that take place during driving. If it does detect any such occurrence, it goes into ‘Limp mode’ – the car’s network’s being blocked and several functions connected to the car’s computer are shut off until the car is restarted. It actually cost only 150$ to build, according to the two.
Valasek explains that “It’s just machines talking to machines. In the automotive world, the traffic is so normalized that it’s very obvious when something happens that’s not supposed to happen.” He also concludes: “I really don’t care if you hack my browser and steal my credit card, but crashing a car is life or death. It is dramatic. We wanted to be part of the solution.”
Car manufactures and transportation authorities have recently started to make efforts in to identify and resolve automobile-related cyber threats. This development stems from the ever rising trend of ‘Internet of things’ and is likely to continue and get more interesting. Last week CyberNation reported on Kaspersky’s survey on the dangers of connected cars.
