New Law Will Install Kill Switches In All New Cars

[redpoint5]

Kill switch for the kill switch.

A battery switch (kill) won’t work. The (DCM: Data Communication Module) has independent back up power. Like if a vehicle is in a wreck and the main battery is damaged. On-star and others still work. Not to mention some have secondary antennas also.

Permalink #13: The Car Hacker's Handbook tells how to assess the attack surface of your vehicle.

It may squeal like a pig in radio frequencies, but if you can still push it what else can it do? I'm not
coming up with other edge cases.

People have tried hacking its ECU for over 2 decades now, with no success.
And that's with directly accessing the hardware, not wireless.
The only wireless communications it supports is locking/unlocking via they key

If something cannot be hacked, does not mean it has no backdoors

Every chip ever made that communicates with other chips has a TX, RX, ground pin for loading programs either from divorced storage or onboard. I have an $30 internet IDE MPX programmer that will talk through those pins at a binary level to read or download anything inside memory address by address. It will even enable a write option to secured memory on supported software.
Last I saw they supported 300,000 various chipsets.

The reason that ECU hasn't been publicly hacked is because there was no interest in hacking it, the hack data wasn't published, or there's an easier/better/cheaper method to replace it. What do you know about my unsucessful reprogram of a Delta high power variable voltage lithium charger?

Not exactly. Old chips really cannot be hacked, because they use technology that allows writing program only once. Some of them allows to erase memory completely using UV and then upload new program, but definitely not to re-write part of the program on-the-fly.

[Piotrsko]

Ok then turn on the UV light and write new zeroes on a replacement. People have hacked programmable HP calculators from the late '70s. There have been some manufacturers that destroy physically the write hardware.

My position is that it can be done if you REALLY want to. Won't be fast easy or cheap

Hmm so your saying I can EOC any car by removing my seatbelt?

Both my cars sometimes believe there is a “passenger “ when there isn’t, so every time the belt light flashes I get a kill

Doesn't work in the F250, havent had a belt undo in the Golf.

It has no real means of wireless communications, uses ROM and my car still has hydraulic power steering as well as cable throttle and a manual transmission.

So no, I don't think it's going to be hacked in any significant way without directly accessing the hardware.
