Gaining unauthorised entry to someone else's car is illegal. Jamming is illegal in the UK. It might be illegal where you live too.
Car key fobs transmit a binary code to the car over radio. If the car recognises the code it unlocks. There are various systems in place to make that process secure. This video is about the way vulnerabilities in those systems can be exploited. Including replay and rolljam attacks.

What are you talking about of course it worked the first time :)
Lmao
Someone hacked your video, too
No worries.
I got the notification the second time, so you got that going for you. I know sometimes CZcams punishes people for re-uploads to fix something. You got it re-uploaded pretty quick.
1:00 Nice detail on the Bmw parking hahah

Mini is owned by BMW.
you beat me to it by like 20 seconds... the timestamp is nice though

"I tweaked some variables, I didn't have a clue what I was doing, but I noticed that it changed things"
- said almost every engineer at some point. That's how you make discoveries! I love your videos, Steve :D
He pretty much summed up my job there... And according to my resume I know what I am doing :P
That's just called debugging
It's like I'm back in my matlab class... **stares of into space due to painful memories**... good times lol
Yep. The real work is going back and figuring out what part of the five different variables you tweaked in "throw everything at the wall until something sticks" mode that made the difference.
"Huh, my code work, and I have no idea why." said the greatest engineer I know.
I love how you can tell he genuinely enjoys doing this. The smile, the laugh, the energy. Keep up the work!!
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).
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.
@@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...
@@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
I also have no idea what I'm doing most of the time.
With all your great research on the topic, how much time is spent coming up with the cool project names vs the actual coding? Rolljam, Magspoof, PoisonTap, Glitchsink...etc. 50/50, right?

I'm not a fancy security expert like you, but I am a software developer working on a web-based fintech app, and... yes, can confirm, a large portion of any development/IT/tech is just trial and error. And lots of banging your head against a desk trying to figure out why the debug output doesn't match what you expect 😂
I like how the poorly parked car was a BMW, that made me laugh.
It's funny cos it's true
Its ironic because Mini is BMW.
Typical
Seeing this comment first then finding the BMW made me laugh.
I laughed as well then I remembered I drive a bmw and also can’t park.
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.
I understand some of these words.
Your sir are a smart cookie. But I'm sure you know that. Thanks for the information. For reasons I do not have the ability to explain. The fact that wavelengths have lengths and how they react to specific objects at different sizes escaped my knowledge. I can confidently say it will not escape it again, at least for another 15 years. So thanks
@@dorjanhajdari2670, thanks. Well, experienced anyway…

I love that you blurred out your key bitting in the opening scene.
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.
Sounds similar to a DDOS attack?
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.
Remember: never park your car next to someone in a hoodie and with a laptop
Just run him over instead
Even if he reserves the spot for you on a busy day?
Specially not someone who looks like the villain in a horror movie like at 1:22 :)
... But the hacker with the hoodie and laptop is in the passenger seat, trying to gather WPA PMKIDs... Do I just not park?
EDIT: Instructions unclear; vehicle is now in lake and hacker is very angry about his laptop getting soaked. Something about SSH keys being irreplaceable?
Remember: don't judge a book by it's cover.
"What this demonstrates really well is that I have no idea what I'm doing." XD
Thats me every day in online school lol
He nailed that so well on the comedic spectrum.
Hilarious!

Your explanations are incredibly engaging and interesting! Thank you so much for inspiring my curiosity :)
Samy is the man. been following his work for years. related, LTC (timecode used to sync audio/video dual system or multiple cams in production) is essentially manchester encoded as well. i have had to actually manually decode it by looking at the bits before lol. silly thing to have to do but it works in a pinch. so if you are syncing your cam using timecode, you may have been using it all this time.
that "hacker sitting in the dark in a hoodie" cliche was so well done. love it.
Doesn't it have proven psychological causality?
Me too 👍
1:00 BMW is the Apple of cars,
Their motto is “park different”
You know Mini is actually a BMW automobile?
Ahh thanks. I thought he made a jab at BMW drivers for parking recklessly which doesn't ring completely untrue in my experience
@@joepbeusenberg Well, yes and no. Yes, as in the company BMW, but no as in the BMW brand. Mini is not part of the BMW brand.
@@DirtyPoul but you will find many components of a mini have bmw on them? Infact the same parts that fit on some of the BMW range.
@@stuartd9741 Yes, of course. Some of the cars share the same platform, so that's to be expected. But that doesn't mean that Mini is part of the BMW brand. It's a separate brand owned by the company BMW. That's what I meant.
Hehehe! I love the hacker face in the dark. :D The green lighting for the call was pretty cool too.
Interesting how far back you have to go for all this. Keys were already code-hopping before the end of the 90s, I think, and your Mini had rolljam projection in 07. I put an aftermarket remote on my Peugot 309 around 03, but I didn't care if it was a good one because it was an 80s 5-door hatch & not even the latest model. Bit of a street sleeper, that one; remarkably fun to drive.
This video is as entertaining as it is informative! enjoyed watching and learnt some seriously interesting tech stuff, thankyou!
To anyone wondering and for the sake of saving history,
This video was reuploaded, because on the first upload it did not have sound in the moments of talking with Samy
Thank you, I was wondering
yeh
Same, thanks
Thank you love you
:D That double spot taking BMW made me laugh!
I clearly saw that it was a bmw and parked like that, but the joke didn't register in my head for some reason lmao
Ironically, Mini is owned by BMW and is usually driven by women.
@@SangheiliSpecOp it is like when you see something so many times your brain ignores it because it is the norm
@@Leo-zt7fo do you have any sources on those car ownership demographics?
@@SentientTent the picture on 1:00 has a tiny BMW logo on the badly parked car.
Something you need to be careful of: replay attacks on cars can cause at least one remote to go out of sync. You might be able to recover it by pressing a button on the second remote, but it'll require resynchronizing it yourself or taking it to someone who can if you're unable to
Thanks for sharing and Samy is a legend no doubt.

Thank you, stole my first car today :)
oh no.
Oh yyyyyyy
Nice dude! Hope you get more cars soon!
Lol
Just unlocking a car is not enough.
Thankyou. This is good stuff.. covered many things in just 20min.
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.

@@matthewkambic4939 Burglary is specific to thievery in buildings. And either the way, the comment states nothing concerning thievery. So it would only be a hacker. But if the hacker stole the car, he'd be a car thief and he'd be commiting grand theft auto

1:18 I liked for this scene alone. YOU LOOK SO SINISTER. That's textbook villain material right there.
a syncronised clock was actually one of the first solitions I thought of! was very satisfying when it was also presented in the video.
I have worked for two different US companies that develop software-defined radios for commercial and government customers. Your opening explanation of rolling codes was fantastic (far outstripping the initial explanation I received when working on our rolling codes project, despite being like 2 minutes long compared to an hour-long briefing at work). Thank you for your dedication to science communication and bringing these awesome aspects of science to the fore!

You could exchange with the car to get the current RTC time, and reduce cost.
It would also prevent changing the time on the keyfob into the future.
i like how you tried to hide the key in the close-up but completly ignored it in the next clip where it's clear enough to be visible

When i saw that car park situation i had to pause for a few minutes for the giggles to go away. 😆
Thank you very much, i needed that.
Alright, I never ever bother to leave a comment but THIS video was so fun, informative, engaging and most of all so damn easy to follow for a beginner like me, hats down!

5:57 That’s soooo Mr. Bean moment!!!! 😂😆🤣
it made my day actually xD
You’re right
That is most accurate depiction of a car park I've ever seen @1:00
Steve does realize that Mini is made by BMW right? 😂
Doesn't matter though, does it?
One of the best CZcams channels I've subscribed to.
Great video interesting content and presentation and also nice editing on the ahh ffff.. moment when the aerial fell off the table!
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!"
Well shit. That's a very good idea that'd definitely get a lot of people to fall into the trap
I don't know about you but if I'm inviting people to my house for a party I'm not trying to steal from them haha. What kind of friends do you keep?
That's not really social engineering, that's just tricking your friends, also why you stealing from your friends?

_"That's not really social engineering, that's just tricking..."_
That's exactly what Social Engineering is:

@@simonseis744 They don't necessarily need to particularly be friends though, this is the sort of attack someone could pull off by investing a few weeks infiltrating say a company so they can produce their party trick at the office Christmas party. Especially easy to pull off given how many companies hire temporary staff during the Christmas period which would give a would-be gang of car thieves a chance to infiltrate the employee social group.

One subtle thing I noticed - the BMW taking up two spaces and parked squiffy, nice touch, I'm not a BMW fan either!
The preamble isn't nessecarily saying 'im a key', it's actually pretty standard. Since Manchester encoding guarantees transitions, this preamble is used to synchronise the receiving clock exactly to the right edges so that the important payload doesn't get corrupted. (Phase locked loop circuit)
0:49 Serious warning. It's unimaginably simple to decode a keys' physical bitting from picture. The entire internet can now unlock your car.
Yep, might not have the digital code but showing your key to the camera is basically the same as letting them take a copy of it to reproduce.
he even hid the key in the first time he showed it
I mean isn't he already showing the whole internet how to unlock his car? Lol
Whoopsie
Lockpicking lawer comes in
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.
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.
"The car door is locked, there's no way to get in." It is a convertible, so very easy to get in, no expensive tech needed, just a knife.

@@davidgustavsson4000 honestly interested in this. I hope it is true. Also hope woman are the ones grabbing the keys so they can fill their keyhole
Thanks for the very interesting video. One question, the part when you talked about when the hacker jams the signal and having the second box monitor the frequency to be able to get into the car. I was thinking, if the signal is jammed before the driver gets out of their car . When the driver presses the lock button on the fob the car is not going to get that signal and remain unlocked. That is, for a period of time before it auto locks. If the driver did not notice that the car did not lock a potential thief could just walk up to the car and open the door and take whatever was in there.
The fact that you blurred out your key was pretty brilliant
The BMW taking up 2 spaces absolutely ended me hahaha
Watching this is like actually doing a project that involves manipulating remote-control keys or key fobs. You have to get deeper and deeper into the specifics of the device you are trying to emulate. It can be sometimes thrilling and sometimes tedious.
Great video. Enjoyed it
This is so fascinating!

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.
