And people wonder why I don’t trust wireless computer connections
In what amounts to justification of my paranoia, even your car can be attacked and infected with a virus if it uses wireless. Lexus cars are equiped with blue tooth wireless communications, and according to a recent article on infosec they are now being attacked by infected cell phones. Even potentially more troubling might be taking yours into the shop and all the cars on the dealer lot get infected. I guess the safest thing to do is to keep 15 feet away from all Lexus’ and cell phones
