I know there's a fine line here and it probably varies by jurisdiction, but aren't there laws that depend on your intention? As in, if they guy would sell this with intentions of good use or even with no intentions at all, even if they knew there existed bad uses, it would be legal, but if they sell it with the intention that it would be given a bad use it would be illegal.
I mean, here they're saying that their intention is for buyers to use them to steal cars.
I'm ok with their ability to sell it. I'm not sure how I feel with the way they're openly admitting that they expect to make their money from people stealing cars.
The Cipher was broken so badly that as far back as 2005 it was published how to break it, and it has still never been changed.
If you have regular access to the car (parking garage) you can just break the cipher if you see it on more than one day... no need to relay at all, and no protections against the relay attack would stop it from working.
It's a 40-bit cipher but because of a weakness you can calculate down to 2^16 possible keys and then come back on another day and break it very quickly at which point you've essentially got your own key to the car.
They would purchase "rollers" or "theft recovery" cars with clean titles.
Roller = a car frame wit VIN and title, possibly blown engine, stripped interior if car was used to race etc.
Theft Recovery = stripped car, no interior, engine etc.
Clean titles made it easy as no inspection was required.
He would steal the same car, transfer parts, discard the frame. You could easily make 15k+ on one car.
Others ship cars to other countries. Same goes for motorcycles.
