A big advantage of Manchester encoding is that every bit guarantees a transition. This means that your signal contains the data and the data rate clock. As you mentioned that the fob can't maintain a consistent transmit frequency, the same is true for the data clock. Manchester allows the receiver to synchronize the data rate. Also, the transmit signal likely starts with the same start byte (most commonly AA or 55) to allow that receiver to lock onto the signal (timing wise) and also adjust its gain (AGC).

[@theodoric4270]

This is important for magnetic strip credit cards, as an example. The card reader needs to know how quickly you're swiping the card and it uses a standard starting sequence to synchronize. It doesn't matter how fast you swipe the card (within reason) as long as you don't vary the speed and the whole strip goes through the reader.

[@donaldviszneki8251]

@@theodoric4270 i always thought this was dumb since maintaining a constant velocity is not always easy. I think a better system is either to use two tracks with a clock track or a second magnetic polarization axis. But magstripe is slowly dying anyway...

[@charlesnathansmith]

@@donaldviszneki8251 it worked well enough, and that's always going to be the standard to hit. When magstripes fail it tends to be from demagnetization or it physically chipping off rather than a rate error From a security standpoint, a lot of the RFID upgrades for credit cards and badges just became "Spooky replay vulnerabilities at a distance" rather than proper challenge/response implementations

Great video! Thanks. It’s worth pointing out that looking at a chip under a microscope to reverse-engineer it is pretty challenging, although not technically impossible if you use mechanical-chemical polishing. Back in 1995 (or thereabouts) when my company at the time was working with something like 2-micron fabrication technology, I was able to diagnose a power-drain by eye-droppering a liquid-crystal solution onto a chip to find the hot spot on the chip. However, even at 2 microns, the image was pretty blurry. 2 microns is about 4 times the smallest wavelength for visible light, so it’s possible, but difficult, to image the chip. Nowadays though, when the features approaching 1/100 the shortest wavelength of visible light, you pretty much have to use electron microscopes, which only show you the surface. So, to see the internal structure, you have to extremely precisely polish off layer by layer, re-imaging each layer. That’s definitely possible, yes, but very difficult.

[@AndyLevy1]

10:19 I think it would have been good to mention here how jamming works in this case. If you are sending out a jamming signal to the car on the broad spectrum, you are not jamming the airwaves so much as you are jamming the equipment. You are causing the car to process useless signals - meaning that the car has no processing power left at that time to process the real signal. You are essentially flooding the car with bad signals, keeping its computer occupied while you listen out for the good signal.

[@putoutmyfirewithgasoline1877]

Sounds similar to a DDOS attack?

[@fbevc]

Actually it has little to do with processing power. The signal you are jamming with is basically noise to the car, and if that noise is "louder" that the actual signal from the key, then all the car "hears" is that noise. It's like trying to have a conversation next to a jet taking off - your voice and the jet engine emit different frequencies, but since your ears listen to the whole frequency range, the jet completely overpowers, but a microphone with a frequency response tuned to the frequency of your voice could hear you.

Didn't mention a relay attack which works with modern fobs with passive unlock (where you can walk to the car and just open the door so long as you have the fob). Two thieves park near a restaurant and observes patrons entering. When they observe a car they want one of them follows the target into the restaurant and walks near them with a transceiver. His partner walks to the car (from which they observed the targets exit from) with the paired transceiver which then relays the passive code from the fob via his partners relay transceiver and the perp opens the door and drives off.

Social engineering: Use your SDR to be receiving. Make an app or script or whatever, so that every time a signal is received it plays an interesting sound clip. Each one is different, and after introducing it everyone will try theirs to see what noise it makes. For example, having a party at home, say "watch this" and get out my key fob, show them when I press the button, an old-fashond "auuuuuga" horn sounds from the home theater sound system in surround sound. Much more dramatic than a laptop sound. "Now try yours!"

[@theocheynel6361]

Very interesting, I love the way you had to think about it as an incremental approach, not knowing what you were doing and figuring it out as you go. A few questions to think about : - When you're jamming the key with your emission, couldn't you just substract what you're currently emitting from what you're receiving, instead of broadcasting on a different frequency ? Kind of the same way active noise cancellation work, if you know exactly what you're emitting then the difference with what you're receiving is what comes from the key right ? - What happens if you press they key while the car is not in range ? Doesn't that mean that the key will skip to the next code, while the car, completely unaware of the fact that you pressed the key, stay on its current code ? Or is the car looking for the code in N possible "future" codes ? If so, what if you press the key N times while away from your car, will the key and the car be "un-synchronized" forever basically ? - Some cars can have several keys am I right ? Back in the day when you had several keys only one of them was remote (which is understandable), but now I think that you can have several remote keys for your car. Is this a more complex algorithm ? Or does the car simply have several registers, one for each key ?

[@svetievboris]

From Wikipedia: "A typical implementation compares within the next 256 codes in case receiver missed some transmitted keypresses." So I guess that probably means that if you click your key more than 256 times while out of range would that essentially brick your key and door i.e. receiver.

[@haydenlandry3837]

Military radio systems use a similar technique to prevent jamming, called frequency hopping. It's like what Samy was saying; you have the two radios with synchronized clocks, and an encryption key determines the pattern of frequencies. The radios "hop" pseudo-randomly but remain synchronous, preventing jamming or interception.

[@sokol7215]

Ir is something complete different than radio. So no, it's not comparable. Completely different things.

[@rolfviehmann6240]

@sokol Actually, I would say it's not that different. In both cases, you have a unidirectional, wireless transmission of a binary code whenever a key is pressed, and in both cases, a device can be built to sniff this transmission and repeat it. So, if a car key would send a simple, static signal whenever the "open" button is pressed, it could be sniffed once and repeated any number of times, which may be possible in rare cases, but since this is quite easy to do, the key manufacturers understand that it's very insecure, therefore better, more complex solutions have been developed. But a simple IR remote control does not need this advanced level of security, therefore, the manufacturers still (to this day) simply send a simple, static signal every time a key is pressed, so once you recorded the signals for all keys that exist, you can simulate all the keys perfectly, any number of times. The manufacturers of the remote controls know that this is possible, but since nobody ever complained about it, they don't care at all. A simple solution (static code) is always cheaper and more robust than a complex one after all. The highest level of security that could be built would be a bidirectional connection between the car key and the car, on other words, a handshake, like when a TLS connection is established, could be made, and then, the actual command could be sent over this encrypted channel. The key would of course only transmit anything interesting after the handshake would have been completed, so no sniffing would be possible at all. As far as I understand it, this is the way wireless keyboards work, to make sure that it's not easy for an aggressor to sniff any passwords you type on the wireless keyboard.

It's ok to be completely lost, i think this is the real hacker's journey! Not knowing anything at first and slowly building up knowledge! Keep up the good work!! :)

I think the biggest issue is with passive entry. Using repeaters to make a car parked in the driveway think the key is next to it instead of in the house.

[@niklas5336]

Regarding other ways to secure keyfobs, you can have the key merely be an unencrypted request for the car to initiate a challenge-reponse. The car sends the key a challenge, the key encrypts/hashes/signs this challenge with the secret key, and the car checks the response. With an only slightly higher level of sophistication, you can measure the timing of the response and compare it against time-of-flight of radio signals. If it's too far (e.g. further than 50m, or about one cycle on a 5 MHz processor), reject the response as invalid. That way you also protect against a signal extension attack.

I wonder if the Mini uses two separate code lists, one for locking and one for unlocking. If yes, then it would be vulnerable to a rollblock attack.

[@f7p1764]

Mini stores last state if it's locked or not, key sends allways one state there is no lock unlock command in key, simple and secure :)

[@Logxnxx]

@@f7p1764 if I understand you correctly the car saves its last state. (e.g. unlocked) and the key only sends one code from one code list (same list for lock&unlock) and thus reverses its state from (unlocked -> locked and vice versa). However. If the key has two buttons and you press the lock button twice, this would be very stupid wouldn't it? because then the lock button would also unlock the car if its already in a locked state. my guess is that two code lists are being used or some sort of encryption is in place that actually hides the state that the key sends.

[@aserta]

I disabled the car key remote, it's exceedingly easy to break into even the most expensive cars. You can see them boast and do it online. The smartest thing one can do, is not play. In a digital world, analog is king. Like stick for automatic drivers and so on. Obviously, there's super easy ways to break analog locks (like Lishi) with relative ease, but that's for common car locks, which a smart owner would've replaced if they really value their car staying put.
