And another new way to nick your car...

Saw this today, knew it was a thing but was interesting to see just how quickly they can get it done.
Got a bit worried and then remembered there's no chance of them picking up a signal from my keys all the way from the front door.

I wonder if it's a consequence of people being told to leave their car keys by the front door so when they break in to nick them you make it as easy as possible and they leave...
 
When are car makers going to hold there hands up an admit that the keyless entry is an absolute joke. Between the relay tactic op posted to the obd port problems or the other thing where they can hold a receiver outside your front door to pick the signal up anywhere in the house it’s ridiculous.
There’s even been instances were multiple cars have been opened on the same street and searched through one after the other for valuables because it’s that easy for them..
No wonder Insurance is so expensive now when they are just rolling 30-50k luxury cars off the driveway never to be seen again. And even if they get caught it’s a slap On the wrist or a few months in prison.
 
That was easy.

Obviously someone had to do a bit of geekery beforehand to create the hardware that spoofs the key but once that part is done you don't need to have the same technical knowledge to use the devices.

Actually the funny part is the idea that to protect a keyless car you should stick an armoured bar or disk on the steering wheel... secured by a key...

Hmm :rolleyes:

Nothing is perfectly secure but if you can steal something quietly and with no damage then the security it has is no deterrent at all.
 
People don't seem to be able to grasp that wireless stuff is not secure. It's being stuck on everything because it's the current fad, but all that's happening is the attack surface for hackers is growing.

Most companies have strong firewalls stopping external attacks over the internet/wire. But all it takes is one wifi printer in the office with crappy security and a hacker can bypass all of that using a laptop in the carpark. It's the same principal with keyless entry.

Wrapping them in foil is also inexpensive and most likely safer as I've done some looking and the majority of Faraday bags don't seem to work 100% of the time.

Perhaps a solid iron box? Although they seem to be harder to find than I thought.


(...or remove the batteries)
 
As long as removing the batteries doesnt cause it to lose sync with the car. Some of the fobs ive used state to change the batteries within a certain time period.
 
So what do they do once they have driven off, or can the box of tricks they had continue to act as a key or be used to make a key?
 
Two trick boxes:

They used one box to receive a signal from a car key inside the property and then transferred the signal to a second box next to the targeted Mercedes on a driveway.

The car's system was tricked into thinking the key was present and the thieves were able to unlock the vehicle.
 
Most modern cars programme their own keys from the OBD port, so once you have the car tucked quietly away in a lockup somewhere you've got all the time you need to programme a new key for it.

Just putting them in a biscuit tin works.
 
Out of interest, I wonder if such a box could pick up the key from a longer distance than the car could, or if it's a limitation of the key? For example my Toyota smart key you had to be right next to the door for it to unlock, probably 1m away is the absolute max.

This is a relay attack. Two boxes are being used.

Box1 is by the key which is apparently near the door and box2 is next to the car to defeat the proximity issue.

Could get creative and follow someone with box1 as they walk away from their car and have the second guy with box2 unlock it behind them...

Highly secure stuff :p
