Ladies and gentleman, Bluetooth is vulnerable:
Security experts have discovered what is believed to be the world's first computer "worm" aimed at mobile phones. The worm does not appear to pose an immediate threat to cellphone users, but it suggests that mobile phones are much more vulnerable to virus-writers and hackers than previously thought.
The malicious code, dubbed "cabir", is a worm that replicates on the Symbian operating system used in several brands of mobile phones, such as Nokia, Siemens and Panasonic.
The worm was anonymously sent to experts in various countries, but has not been detected circulating among cellphone users. It propagates through the "Bluetooth" wireless technology, repeatedly sending itself to any Bluetooth-enabled device that it can find, regardless of the type. The worm will not damage a phone or its software but shortens the device's battery life by constantly scanning for other Bluetooth-enabled devices.
