Some race condition that causes a duplicate signature to be generated, or causes the same signature to be sent to two different cars doesn't seem too outlandish to me. I have seen similar bugs before. The only thing that is coincidental is that the duplicates ended up in two vehicles near enough to each other for the mistake to matter.
- fnordpiglet 4y agoBoth cars unlocked and presumably started at different times for different people, so it would have had to have been simultaneous of two identical race conditions on two different sets of devices at different times. This feels like total bs.
- stonemetal12 4y agoNo, I am suggesting one race at the factory that gave the two vehicles the same private key. Therefore Person A can always access Person B's car and vice versa because they use identical keys.
- fnordpiglet 4y agoMaybe, but that seems unlikely - this would also mean any time one car is unlocked the other is too (presumably if done by app not BLE)
- stonemetal12 4y agoYeah, now that I "said it out loud" it seems like if that were the case, there would be instances of them using the app while you are driving or near your car. You would know "something" is wrong with your car even if you don't know what exactly.
- lamontcg 4y agoYeah when I worked at Amazon we found two computers with NICs with identical MAC addresses (and it was a long time ago when Amazon had an awful lot less servers). Some database process at the manufacturer had a race condition.
