not sure how big a threat this really is. besides the difficulty of infection (bluetooth being slow and limited range to begin with) there is the actual trouble of infecting something vital. a lot of cars computers functionality is still hardwired into it. a BCM (body control module) can not be reprogrammed to act as the PCM (powertrain control module) or as a EBCM (electonic brake control module, aka abs/traction control/stability system). furthermore the actual programing of any key module can not occur with the engine running, and often can require fuses to be pulled as well as a key cycle to be made. the changable software is stored on EEPROM chips, while the base factory code that provides the basic functionality is stored on EPROM chips and ROM. so unless a module has been design to recieve and proccess new software rapidly (such as with navigation systems), the threat posed is basicly non existant.
second is communications. currently there are multiple bus protocols used on vehicles as well as multiple netwrok designs. until it is required for all vehicles to use a CAN bus, any virus created will have to be engineered specificly to travel along a given model/years internal network.
crxforum, at the core you are misunderstanding the purpose and implemintation of OBD/OBDII standards. the suggest you are making about it, is at its core false, nor applicable to this threat.
