alphadogg writes "University researchers have taken a close look at the computer systems used to run today's cars and discovered new ways to hack into them, sometimes with frightening results. In a paper set to be presented at a security conference in Oakland, California, next week, the researchers say that by connecting to a standard diagnostic computer port included in late-model cars, they were able to do some nasty things, such as turning off the brakes, changing the speedometer reading, blasting hot air or music on the radio, and locking passengers in 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. Other experts describe the real-world risk of any of the described attacks as low." Here is the researchers' site, and an image that could stand as a summary of the work.
