I want to know the answer to the following question:
Wifi, bluetooth, and cell phone networks are examples of what?
All the background I'm provided with is that "Researchers in 2011 were even able to use a malicious compact disc in a car's stereo system as a successful attack vector, and cars with built-in voice recognition or remote assistance features have onboard microphones which could be used for eavesdropping.". Is that enough to answer the question?
Answer: no
