My hypothesis is that the construction of gas pumps were using parts that have Bluetooth features that although not used by the pump or the station, are left in for speed and cost.
There are many single board computers that have BT, WiFi, and other radios enabled and forgotten.
For example, try to get a laptop that does not have a built in camera. It is significantly higher price that with camera. I am guessing similar is happening in gas pump manufacturing.
The firmware stack would also fall into the similar 'laziness'. "The [chip/radio/whatever] driving library is already made, why recompile it without the BT when it could be working right now"...
- ryandrake 3y agoJust having an unused radio on the motherboard wouldn't necessarily be a meaningful attack surface. That radio would somehow have have a software path of some sort up the stack into the application business logic that controlled the pump. Unless this was something as basic as a root shell from the BT driver, there must be some participating software in there somewhere.
- CyberDildonics 3y agosimilar is happening in gas pump manufacturing. What are you basing that on? why recompile it without the BT when it could be working right now Why would someone recompile anything when they could just turn it off?
