Cars can be hacked so you suddenly loose control of your brakes, steering, acceleration, turning and gauges : https://www.forbes.com/sites/andygreenberg/2013/07/24/hackers-reveal-nasty-new-car-attacks-with-me-behind-the-wheel-video/
Inexpensive, inconspicuous hacking devices can be quickly wired into a car's network to seize control of the auto's computer control systems: https://www.forbes.com/sites/andygreenberg/2014/02/05/this-iphone-sized-device-can-hack-a-car-researchers-plan-to-demonstrate/
Security reseachers have also shown that it's NOT even necessary to physically connect directly into the vehicle's wiring. A car’s OnStar-type cellular connection, Bluetooth system, Android apps that synch with the car’s network from passengers' smartphones and even malicious audio files on a CD in the car’s stereo system, ALL can give evildoers remote control of your car.
Fortunately, security researchers who studied and documented these vulnerabilities have also found inexpensive ways to prevent or protect against them: https://www.wired.com/2014/07/car-hacker/
The flaming auto photo at the top of this post is Michael Hasting's Mercedes ablaze on June 18, 2013 in Los Angeles with him in it. Many believe his car was hacked to assassinate him.
Michael Hastings was the famed investigative reporter whose Rolling Stone article, Runaway General, prompted President Obama to ask General Stanley McChrystal to resign as commander of all US and NATO forces in Afghanistan. General David Petraeus replaced McChrystal.
The night before he died, Hastings begged his neighbor to lend him her car because he felt his Mercedes had been tampered with. The neighbor declined. Shortly thereafter, Hastings drove his Mercedes and died in a bizarre, fiery crash.
Hastings was working on another blockbuster article at the time he died. He was very fearful and wanted to leave Los Angeles.
Richard Clarke, Former U.S. National Coordinator for Security, Infrastructure Protection, and Counter-terrorism under Presidents Clinton and Bush, commented on Michael Hastings' death in the Huffington Post:
"There is reason to believe that intelligence agencies for major powers -- including the United States -- know how to remotely seize control of a car."
"What has been revealed as a result of some research at universities is that it's relatively easy to hack your way into the control system of a car, and to do such things as cause acceleration when the driver doesn't want acceleration, to throw on the brakes when the driver doesn't want the brakes on, to launch an air bag," Clarke told The Huffington Post. "You can do some really highly destructive things now, through hacking a car, and it's not that hard."
Will we ever be sure of the truth about Hastings' death?
The New York TImes reported car hacking as early as March, 2011. News reports say Hastings' car's engine was thrown 50-60 yards from the crash site. Eyewitnesses claim explosions occurred before impact.
RIP Michael Hastings.
