UK - Thieves are using Bluetooth phones to detect whether motorists have left laptops, mobile phones or state-of-the-art PDAs in their cars.
PC Davis said: "Even if they are out of sight in the boot or glove compartment, the Bluetooth technology enables computer-literate thieves to locate compatible kit easily."
When a car contains a Bluetooth-enabled laptop, a signal on the screen of the thief's mobile displays not just its presence, but also its make or model.
The thieves then have an easy target and the expensive laptops are often stolen to order.
PC Davis said: "Blue-bugging techniques can also be used to hack into mobiles, which are increasingly used as portable data stores, with details such as passwords, PIN numbers and other sensitive information ready for the taking.
"These days, a great deal of confidential company information, bank account details, private emails and so on are accessible through laptops, PDAs and even mobiles.
"People should realise that as well as equipment losses, they are at serious risk of corporate data theft if Bluetooth devices are left enabled and unsecured." (more)
