CyberChef VS TeslaMate

Then we take the encrypted text and use CyberChef to decrypt it.

Let's go to CyberChef and insert our pieces of evidence.

A parameter was changed from '2AMBCgIQBg' to 'CgIIAdgDAQ%3D%3D' which is just the correct base64 encoding they should have been using the entire time.

I don't think this was a hostile action by Google, I think someone just added better input validation for security reasons and it accidently broke the bad requests they were sending.

❗This is indeed the flag, but the text is encrypted with Base64. Usually, the presence of padding character "=" indicates that's Base64 type of encoding (but that's only one of the hints). To decrypt it, we can use CyberChef. Copy-paste the text and we either:

It uses a combination of magic bytes (like the `file` command), entropy analysis and character frequency detection to determine whether an output is likely to be of interest to the user.

The file type mechanism is written here[0]. There's a list of all signatures we detect here[1].

I think this can be deciphered using CyberChef...

The graphs linked above were generated by a self-hosted application called TeslaMate, which connects to the Tesla API and harvest data as you drive, so I've got fairly extensive "health stats" for the Tesla I've owned. TeslaScope is a cloud based equivalent, which is cheap, and I also use, but mainly as a backup to my TeslaMate instance.

Interesting, that would work. I didn't know teslafi can CONTROL the car. I'm using teslaMate, which is basically read-only.

Does anyone have experience with a self-hosted solution? Something like TeslaMate or TeslaLogger?

So Tesla drivers have TeslaMate which is a self-hosted data logger for their car's trip data. Anyone aware of anyone building a version of this for our EV6s? The Kia Connect infrastructure claims to have an API. Would be cool to develop something like this for us.

I just referred to a couple of legs from my trip from Sydney to Adelaide with the pod on (using Teslamate) and compared it to another more recent one without the pod on. The last of the three will probably give the best example as it is while driving the Hay Plain which is one of the most boring, flat roads you could imagine. It was during the COVID lockdowns so basically no traffic either.
