Lexus is denying claims that the Cabir worm poses a threat to Bluetooth capable navigation systems on their vehicles. The denial rebuffs claims made by a Kapersky Labs, a Russian IT security firm, that Lexus navigation systems could be infected with the virus via infected Bluetooth enabled phones. Kaspersky Labs now says that no cars were actually found to be infected, and that the inquiry was posed by a customer who was curious as to the vulnerability of the navigation system on some Lexus models. While the possibility of infection does exist, it appears as though the worst case scenario would be an error message would be displated on the navigation system screen. Lexus owners should have little to worry about.
