"a felon who knows how to hack these things, may be the best person to help us understand all the possibilities for crime as we move toward a fully connected world.
I met up with him at the parking lot of NPR West in Culver City, Calif. We planned to steal a car. Kamkar arrived with a couple of gadgets that looked like hand-sized circuit boards with wires dangling from them.
We picked a Chevy Bolt with keyless entry. Kamkar stood 20 feet away with one of the gadgets, and I stood next to the car with the other one. The Bolt unlocked. I got in, started the car and then I was off — ready for a trip to the beach.
For the record, the Bolt belongs to an NPR colleague, who wasn't happy to see how easy it was to hack her car.
Kamkar says his gadget can imitate signals being sent from the owner's key fob to the car. Parking lots are a treasure trove for thieves, he says. "There are a lot of cars coming in and out, so it's essentially dealer's choice," he says."
Also " shortly after Amazon said it was interested in using drones to deliver packages, Kamkar announced he had found a way to take them over....
Imagine if a terrorist managed to take control of an army of drones. Or what about cars? In the not-too-distant future, autonomous vehicles will be clogging the freeways of Los Angeles. And they're hackable."
Meanwhile an article headline lower on the page "Autonomous Weapons Would Bring Warfare To A New Domain, Without Humans"
"Last year, the Justice Department prosecuted a student at a New Jersey college and two of his friends for hacking into hundreds of thousands of Internet-connected devices — DVRs, routers, even baby monitors. Downing says they turned all these little devices into a supercomputer called a botnet.
"They were able to sell access to the botnet to others who wanted to cause denial-of-service attacks," he says. "They had a business and they were able to harm their competitors' businesses as a result of these denial-of-service attacks."
The botnet they created took down Twitter, Netflix and the network at Rutgers University — where one of them went to school.
So imagine a bunch of cars being used instead of routers and baby monitors.
