Car hacking is not a new field, but its secrets have long been closely guarded.
That is about to change, thanks to two well-known computer software hackers who got bored finding bugs in software from Microsoft and Apple.
Charlie Miller and Chris Valasek say they will publish blueprints of techniques for attacking critical systems in the Toyota Prius and Ford Escape, following several months of research.
The two "white hats" – hackers who try to uncover software vulnerabilities before criminals can exploit them – will also release the software they built for hacking the cars at the Def Con hacking convention in Las Vegas this week.
They said they devised ways to force a Toyota Prius to brake suddenly at 80 miles an hour, jerk its steering wheel, or accelerate. They say they can disable the brakes of a Ford Escape travelling at very slow speeds.
But, the two scientists were sitting inside the cars using laptops connected directly to the vehicles' computer networks when they did their work. So they will not be providing information on how to hack remotely into a car network.
The two say they hope the data they publish will encourage other white-hat hackers to uncover more security flaws in vehicles so they can be fixed.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
