Hacker May Have Discovered Plans For A Tesla P100D (jalopnik.com)

Posted by BeauHD on from the white-hat dept.

One computer wiz claims to have hacked into Tesla's firmware and discovered a reference to a juicier battery. Self-proclaimed white hat hacker, Jason Hughes, says he discovered a secret in Tesla's firmware 7.1, but he didn't want to tell the world outright what he discovered, so he made Tesla Motors Club forum-members work for it by obfuscating the secret with a hash. TheSHA256 hash, a one-way function, would either require forum members to guess and check to decrypt this code, or to look it up in a hash directory. Forum member LuckyLuke decrypted Hughes' hash and discovered its meaning: P100D. P100D is the nickname given to Tesla's upcoming 100-kWh battery pack that would give the Model S a range of 300 miles or more. In response to a fellow forum-member decrypting his secret code, Hughes responded on Twitter. On the forum, Hughes had some additional information to mention, saying: There have been references to the P100D in firmwares as early as 2 months ago. They finally added the badges to 2.13.77. I mucked it up a bit by adding a crappy background (it's a PNG with transparency in the firmware)... There are quite a few things that are in the firmware that I'm not prepared to share publicly. Just like the P100D has been in there for months with my lips mostly sealed. I don't want to spoil all of Tesla's surprises.

    Seems the guys' Tesla automagically downgraded its firmware after the discovery was made public. Musk's answer is priceless.

    1. Are you actually white hat if you're spilling secrets that aren't yours to tell?

    He looked at the firmware that was installed in a car the he (I presume) owned, and published his findings. If you want to keep something like this a secret don't distribute this "secret" in a firmware update that every single Tesla owner receives.

    Cheers!

    Dammit I won't consider an electric car until it can do at least 100 miles one one charge!

    What? Oh okay.

    Dammit I won't consider an electric car until it can do at least 200 miles one one charge!

    What? Really? 200miles? Already. No I definitely did not say 100 miles previously. Okay.

    Dammit I won't consider an electric car until it can do at least 300 miles on one charge! AND I reserve my right to change my view with every new breakthrough in the electric car market!
