Android Malware Used To Hack and Steal Tesla Car (bleepingcomputer.com) 118

Posted by msmash from the security-woes dept.
An anonymous reader writes: By leveraging security flaws in the Tesla Android app, an attacker can steal Tesla cars. The only hard part is tricking Tesla owners into installing an Android app on their phones, which isn't that difficult according to a demo video from Norwegian firm Promon. This malicious app can use many of the freely available Android rooting exploits to take over the user's phone, steal the OAuth token from the Tesla app and the user's login credentials. This is possible because the Tesla Android app stores the OAuth token in cleartext, and contains no reverse-engineering protection, allowing attackers to alter the app's source code and log user credentials. The OAuth token and Tesla owner's password allow an attacker to perform a variety of actions, such as opening the car's doors and starting the motor.

        • Personally, I don't really fault the makers of the Tesla app very much. Even if they had encrypted the OAuth token and taken more security measures, once the phone is rooted by some rogue app, there's only so much you can do.

          It's similar to the problem of Filezilla storing FTP passwords in plaintext. Once you have malware on your machine, encrypting the passwords is going to do very little to protect them, since there are so many other ways to attack the system to get the passwords. There's also a simple f

      Tesla has its part of the blame. Not for the car, but for the Android app. Probably outsourced it to a webdev firm.

      It is Tesla's fault. Why?

      They decide which target sdk and which min sdk version they support (compile sdk doesn't really matter for liability purposes). They should be aware of the consequences of supporting older versions. If they use a feature that is vulnerable in one of the versions they support, it's CLEARLY their fault ;-)

      The difference is that the victim will have a much harder time convincing their insurance company and the cops that they weren't negligent and aren't running a scam.

      There was a spate of thefts of BMWs and other expensive cars a few years ago. No alarms, no broken glass, cars driven away despite having immobilisers, victims accused of losing the keys etc. Turned out that you could prevent the car from locking properly, then once inside use the OBD-II diagnostic port to clone the keys and drive it away.

      • Apple makes much profit, I am constantly reminded because people don't understand technology. Elon was so concerned that people wouldn't understand Autopilot that he had to put a page in the manual. Can Tesla confirm that people are properly educated on this?

They need help in the Apple Store setting up a MacBook for crying out loud.

    • I don't know, this does sound a little bit like blaming Ford because your car was stolen when you handed the keys to some guy wearing a red coat and hat outside a posh restaurant. Is it really a security flaw with your car if the restaurant doesn't actually have valet parking?

      And from the other article someone posted above, this apparently requires that you have the Tesla app on an out-of-date Android phone, the flaw used in the demonstration to steal the OAUTH data has already been patched...

      • As a Tesla owner, I didn't put the app on Android. Therefore it is more like Tesla handing your keys to some guy wearing a red coat and hat outside a posh restaurant. Or at the very least, it is like handing the valet the key that isn't supposed to open the trunk but yet finding something from the trunk missing because there was a flaw with the key that allowed the valet to open the trunk after all.

Hell, Tesla even brought one of its cars to Defcon in 2015 and had it on the main floor, inviting people to try and hack it as advertisement for said program.

    To use this one would have to specifically target the android phone of a specific Tesla owner.

    If someone wants to steal a specifically single person's car there are vastly easier ways to do it. Such as, hold a gun to the person's head and demand they turn over the key.

    None of this was done in the wild, making the title needlessly click baity.

  • Trying to prevent reverse engineering is pointless, all you can do is make things more difficult and in doing so, making your code more complicated and harder to debug or potentially unreliable.
    The fact is if you access something from a compromised device then you run the risk of whatever you're accessing being compromised too.

  • You mean I have to switch to an Android to steal Teslas? I'm sorry, but that's a deal breaker.

  • and you're simply doing what you were told

  • So let me see if I understand correctly, if you download and install malware on your Android device, you'll get hacked, just where is the technology angle?

  • Teslas are 13x less likely to be stolen than an average car according to Teslas are hard to steal [businessinsider.com].

    The reasons are multifold. Starting the car and driving it off is the easy part. The few Teslas stolen to date have been largely due to what might be considered extreme negligence on the owners part - like leaving the doors open and the fob inside.

    But is that negligence? The car is totally connected and obscenely trackable. Getting away with stealing a Tesla would mean disconnecting it forever and thus losing a lot of its value. For example, you could never get a free recharge. I wonder how many of those few cars stolen have been recovered. I'd bet the number is high.

    So, you steal it for parts? Wrong! There is virtually no used parts market. Tesla owners tend to buy their parts new.

    It seems that the best you could hope for is likely a very quick joyride.

    My question is "why this article now"? It is very sensationalist. I'm not questioning the efforts of those who found and reported the attack route. But why widely disseminate it to the general public without noting that Teslas are amongst the least likely to be stolen cars in the world. Is this an attack piece?
