I want to know the answer to the following question:
What were researchers in 2011 able to use as a successful attack vector?
All the background I'm provided with is that "Connected cars may use wifi and bluetooth to communicate with onboard consumer devices, and the cell phone network to contact concierge and emergency assistance services or get navigational or entertainment information; each of these networks is a potential entry point for malware or an attacker.". Is that enough to answer the question?
Answer: no
