A Russian security outfit is speculating on the possibility that a virus could infect a Lexus’s firmware, using Bluetooth as a vector.

It’s not clear whether or not this has ever actually happened, but apparently someone asked Kaspersky Lab if they knew “how to cure a virus, which ‘infected the onboard computers of automobiles Lexus LX470, LS430, Landcruiser 100 via a cell phone,’” and they conjecture that a virus could potentially use Bluetooth to jump from a Symbian-powered cellphone to the navigation system of certain Lexus models.
