Hello all, I've recently spoken to a cyber security friend of mine. It appears there are security risks with using a wifi or bluetooth enabled OBD II adapter. I recommend you consider switching to a cable attached version, if you live in a densely populated city or large town. Apparently, it wouldn't be too difficult to engage or disengage critical systems like brakes. I would say the nature of this attack vector and the security of the ECU makes it uncommon. Most drivers are not using always-on wifi OBD II adapters, so most malicious attacks will come from other vectors. If any of you know someone with an alternate opinion based on his/her personal experience with CAN bus ECUs in modern autos, please let me know!
