That's according to security researcher Nitesh Dhanjani, who spoke about his findings at a recent hacker conference in Singapore. All it takes is cracking a six-character password, considered low-hanging fruit in the cyber security world.
And if it can happen to a Tesla (TSLA), other cars may also be susceptible. After all, many modern cars made by others like Ford (F, Fortune 500) and Toyota (TM) can also be controlled via computer and mobile phone apps and come equipped with wireless connections that tap into Wi-Fi, Bluetooth or cell phone networks.
"We now have ways of accessing our cars we never did before, and consumers aren't quite aware of that. Hackers will try to take advantage of that lack of awareness," said Erik Cabetas, managing partner at the consulting firm Include Security.
Dhanjani said today's cars should be held to a higher security standard than the average laptop. Not only are they more expensive, but losing control of a car can put lives in danger.
