When you think about the technology that runs our automobiles these days, it’s quite impressive. Not only have they made our driving experience much more comfortable, but also much safer. (Anti-lock braking systems, airbags, electronic stability systems, traction control…..just to mention a few.) Even though the computers that controls all these system are usually quite reliable, we know that they can have their flaws as well.

University researchers have taken a close look at the computer systems used to run today’s cars and discovered that hacking into a cars computer system is really not that complicated. In a late 2009 demonstration, they hacked into a test car’s electronic braking system and prevented a test driver from braking a moving car. In other tests, they were able to kill the engine, falsify the speedometer reading, and automatically lock the car’s brakes unevenly. They ran their test by plugging a laptop into the car’s diagnostic system and then controlling that computer wirelessly, from a laptop in a vehicle riding next to the car.

The point of the research isn’t to scare a nation of drivers, already made nervous by stories of software glitches, faulty brakes and massive automotive recalls. It’s to warn the car industry that it needs to keep security in mind as it develops more sophisticated automotive computer systems.
