1000s of Porsche's in Russia remotely bricked due to software?

[PalmerWMD]

1000s of Porsche's that were legally purchased and are not stolen have been bricked in Russia via the anti theft.

I am not on here to discuss the morality (as most seem to have gone insane on many issues in the past 20 yrs) but I simpkly pose the question.

Is this possible with Nissans?
Do we also have a factory kill switch?

If yes which ones?
From about which model year on?

Did my disconnecting the telematics antenna help ( I doubt since this shuts down active data sending from the vehicle not reception via GPS and the like)
If Porsche has a kill switch does everybody?

I heard the workaround in Russia has been, the former franchised Porsche (who now most sell eiher grye market cars or chinese cars) dealers uninstall the factory anti theft box and perhaps reflash the ECU to make it not complain about his missing module.

Dont think it cant happen to you who knows what the future will bring.
In Germany for example by some reports bank accounts were getting cancelled for folks who dared to oppose the COVIS restrictions and called them bad science ( which we now know they were correct)
One example I am tracking is Tim Kellner former Police Kommissar who become politcally inconvienient when he pointed out too many unpleasant facts about the german crime rate.

So fundamentally does anybody know , what the status is with Nissans?
And which model years it started for some model lines?

And even if this was just a satellite system failure after (which some maintain), it still begs the kill switch questions.
Because even if it was just a malfunction*, it proves the existence of a functional kill switch, malfunction or not.

* Moscow has a GPS defense system which scrambles GPS signals to make ukrianian targeting much more difficult and this scrambles and alerts certain types of vehicle anti-theft.
This is a theory that has also been presented. On the other hand only Prosche's seem affected...

Anything with telematics is basically brickable. Sirius handles all of Nissan's telematics systems, so individual cars could theoretically get bricked by spoofing Sirius signals and the whole fleet could theoretically be bricked by a hack of Sirius' systems. Without telematics the answer is no, the CAN gateways act as both isolation and watchdog on the AV system (which is the only external pathway an attacker could use). The AV has its own leg of the bus and an attacker would need to find a path past the gateway in order to spoof the security system. That's a vastly more difficult exercise and probably impossible without physical access to the vehicle.

[PalmerWMD]

Thank you for the quick answer!

So just to make sure i understand:
With my telematics antenna disconnected there is no remote access to the CAN gateways for an attacker and remote kill switching wouldnt work?
(That is the only defensive measure I have right now, until I moved to EU, my factory Nav still worked though even after telematics antenna disconnection, as did my Sirius receiver until I let that expire)

The navi is part of the AV system, that whole bus is watchdogged. Your phone could still let an attacker in, but the damage would be limited to devices on the AV bus (principally the AV hard drive). The gateway would prevent any AV devices from sending spoof commands to the rest of the vehicle, so nothing there can brick you. Nissan did that deliberately (and wisely) when they changed from straight VCAN to a gateway construct. Telematics is different because bricking the vehicle is a valid part of its job through Nissan Connect if the vehicle is stolen or misappropriated. So basically yes, as long as your telematics is disabled then so is its ability to disable the car.

Thank you, sorry for being a but dense but this is not my wheelhouse.
Is there a telematics module in addition to the antenna thats needs disabling?
Or just the antenna disconnection will do?

[VStar650CL]

Nope. The telematics module (TCU) is indeed separate, but With the GSM antenna disconnected it can't talk to anybody on the outside.

So the car uses the telematics antnenna not just to send date but also to receive instructions?
So when I disconnected it ,I prevent not only the car reporting its location, but a "stop" command being received from Nissan?

[VStar650CL]

Correct.

[VStar650CL]

Well, let me slightly revise that. In theory they could also send a command to the car via the satellite radio antenna, but that's a one-way interface and to the best of my knowledge they don't use it that way. But to be 100% certain nothing can get out or in, it occurs to me that you should also pull the plug on the SXM antenna.

I had no idea this was a thing.
