This Toy Can Open Any Garage

Or almost any garage - it's particularly good with fixed code gates and garages. Samy proposes other weaknesses with rolling codes.

I don't condone malicious hacking of gates, garages or other property. The point of this video was to discuss how it could be done using fairly basic technology like this toy that was originally intended as an instant messaging device. I learned a lot in making this video about how codes are sent and received, how they are encrypted or not encrypted. I found out how hard it is to execute in practice something which in principle doesn't seem that difficult.

How do you lock pick a garage

[@aceggkspade958]

Hahaha that guy is a beast

[@aceggkspade958]

@@krishnaearth1624 you don’t need to lock pick it. You get a long strong wire slip under the rubber flap at the top, grab the rope where the red handle is and yank. It pulls the garage off the track. That’s why having a security system is a good idea. Cameras too. However a do it yourself security system runs into its own problems. New ones today that interact with Google home or Alexa, can be manipulated to shut off or open the garage via voice commands through lasers hitting the diodes on those devices from outside. It’s tricky but totally doable. Also DIY kits don’t really call anyone but you, jam the cell single and nothing can be done. Then you have security systems like ADT’s new ones or Xfinity or other cable services that literally call through your internet. I’m sure you see the downfall here, a power outage shuts off the internet, so the easiest way to replicate that is just to go to the power box and cut the power from the main breaker outside by the meter. Which surprisingly a lot of homes have it outside. Only homes built after Net Metering Meters were put up by electric companies about 10 years ago, have their main breakers inside the garage. Unless specifically requested for a sub panel to be put in. So shutting down those systems is pretty easy. Then you have systems like simply safe. They are funny because even the company says, don’t advertise your sign or hide the main panel which is like a vase you plug in that calls out. They tell customers to do this because you plug it in, and with in 30 seconds if someone breaks in and unpluggs it, even though it’s monitored through cell signal it won’t call anyone. But you can go one step further. If you use a 350mega hurts radio transmitter, which sells on Amazon for a cool $3. You just press the button, hold it up to the door, open the door and close it and your in with out the alarm going off, because you jammed the signals and simply safe and other cheap DIY monitored systems don’t have sensor jam detectors that actually trigger the alarm. They just send out a notice that your door isn’t working right. Which people ignore. Ok so at this point your thinking what about cameras. And shutting off someone’s power renders them useless. Even if they are arlo cameras that use mini solar panels that charge the camera so they don’t need a power source if your gone from the home, the power shuts off the internet and therefore the camera can’t send out any videos to you in live stream. So Ring, arlo, and all the copy cats, are no good. You can still see later what happened but a guy with a mask doesn’t show anything aside from you getting duped. So why do criminals get caught and how can you protect yourself. Well to answer the first question, most crimes of theft are opportunity crimes. Your door handle was unlocked they checked it and stole stuff inside and ran. You left the garage open and someone popped in and grabbed something and ran. But they get caught because other people see them and call the cops. They are usually on foot and teenagers Or homeless looking for money walking down the street at night checking door handles, typically don’t have cars. Either way, no get away car, makes catching them easy, and most streets have nosey neighbors. The second reason they get caught is because they are stupid. And this is probably the biggest reason. They don’t know any of the info I just said, and furthermore don’t case their homes properly or even pay attention. I can spot all these things with in seconds of stepping from the sidewalk on to the driveway. But I don’t steal, I sell people home automation and security systems, or I did for 10 years. I sell solar now. But it’s a craft. So what’s the best system for your money. Ok let’s start with cameras, make sure they record off movement, have at least two night vision infrared lights and send video spliced into 30 second clips in real time. That way you can see at least one clip before anything can be done. Cameras with a power source are best. Placing them high up is good too. Also Vivint has them where they even whistle or make other noises like an alarm to detour people. Get cameras that have two way audio also, and run on their own undiscoverable WiFi or cellular network. Next, your security system needs to be monitored cellular, I didn’t mention this before but old systems use land lines which can be cut. The cellular needs to be two way connected at all times. So if cell jammers are used or breaking in and ripping the panel off the wall and smashing it, the company knows they aren’t receiving signal instantly and call you. You will most likely see at least one clip of a criminal and tell them to dispatch police. The sensors need to have sensor jam detectors, like what happened with simply safe, if a Vivint sensor gets Jammed it will immediately sound the alarm. The system needs to be a two way voice, so the monitoring company can click in and hear what’s going on inside, like someone giving the wrong verbal password or saying take the tv out the back, or dogs barking or glass breaking. This is super important, especially in higher crime areas. Police don’t respond quickly or sometimes not at all to alarm companies unless it’s a confirmed response, and two voice is how you confirm the response to get police out there ASAP. And lastly, only have home automation that can do things like lock a door, arm the security or close a garage via voice commands through Alexa or Google, not the other way around. That way no one can yell or use lasers to have the doors respond to open a garage, unlock a door or disarm the system. Vivint’s are programmed in that matter. Now I say Vivint a lot, because they have the best system money can buy hands down. I’ve worked for 7 different companies and Vivint’s the best by far. They thought of everything, I don’t even work for them right now so you know I’m telling it to you straight. The one thing Vivint didn’t think about was paying their managers better so I left lol. But for customers, it’s the best most secure alarm you can get. Hypothetically you can still break into one but it will be hard. Also it’s a serious crime and I would never recommend doing such a thing. But hypothetically if you did, You would have to probably hide in a tree, and hope someone disarms their system via the touchscreen panel. Where at the right vantage angle you might be able to see the password. Then one day when they are gone, hop the fence, cut the power so WiFi is gone for outdoor cameras. Do not use the front door, Bc that doorbell cameras is on cell signal and you can’t stop it from sending out recordings. Then head to the back door. You’ve already cased the house so you know it’s an older sliding door, where they don’t have these rubber pads at the top of the door frame. Meaning you can get a screwdriver and wedge it under the slider and lift it upwards, so it renders the lock useless Bc you will lift it so the lock disengages. If there’s these pads at the top on the inside of the door you can’t do that on newer sliders. But you got to do it quick. And in 30 seconds get in and type in the code to shut the alarm off. Or someone will call after that even if you disarm it with the code. Now you can go to the front door, and either unplug the doorbell camera if it’s not hardwired in, or if it is get your drill and drill into the wall and cut the wires for power. Then proceed to the garage and open it up and tell your buddy down the street to pull the moving van up to the house so neighbors don’t get suspicious. Be quick and your gone.... of course again, it’s all hypothetical. And if you have never been robbed, it’s a terrible feeling that takes people months or years if they ever get back their full peace of mind. It’s a terrible thing to do to someone else. They are your fellow man, the same species and your neighbors. Don’t steal or break into someone’s property of any kind. There are always honest options to your problems, and those are the best ones. However, in the video game hypothetical scenario we discussed above, I’m sure you would agree that’s a ton of work!!! That’s really time consuming, you could get caught a week prior just casing the house or up in the tree. It’s super risky. Which is why a criminal just goes to the next house who doesn’t have a Vivint System, or really any system at all. Anyways I hope that answers any questions you had, and all the ones you didn’t haha.

You need a newer system with digital codes since the frequencies drifted with the old ones.

[@jamessnook8449]

I used to write firmware for security receivers, and a lot of inexpensive garage door openers are simple 8- bit pulse position format, but as you guys found out the timing is everything. The codes I used were PPM and PWM and 24 to 32 bits in length and sometimes included hamming and grey encoding, but the reception windows were very tight ( to about 50uS) and in some formats they used a sync pulse to specify the widths of the pulse windows so the timing would be different in different conditions.

You don't need a transmitter or toy to open most garage doors. Here is a little known fact that has come in handy many times during power outages before I installed a battery back-up. In most garages, the latch at the inside top of the door that connects and disconnects with the center guide rail is easily accessible using a wire coat hanger. Just slipping a wire coat hanger between the door frame and door with the hook part to catch and release the latch with a downward yank will open most garage doors. Thieves know this, so should you!

In the "good old days" you often had the garage simply have an inductive loop outside, drive up and door opens. Inside you then pressed a button by the door to open it from inside. The times when you parked your car, and went inside leaving the keys in the ignition with not a care.

[@Bacopa68]

Ignition controllers started being made much more robust and shielded than they used to be once FM radios started becoming standard equipment in the 70s. Older ignition systems could interfere with FM radios. These changes have made cars much less vulnerable to nuclear electromagnetic pulse. The radio itself is now the most vulnerable part, but it should blow out its fuse before the surge can damage other parts of the car.

More importantly, this is only for the wake-up "hello" to the RX radio transceiver - and it has a few extra features: rate limiting (one attempt every 3 seconds), and packet size (128-bits). After the RX radio wakes up it begins a secure bidirectional session with elliptic curve with pre-shared public keys (from setup), HMAC, time limits (RTC), and a counter. It has a full wake up, Car-to-Fob, Fob-to-Car loop time of 1.5 seconds - slower than your off-the-shelf car alarm or factory remote, but it's not going to be replayed, spoofed, or MiM. Was a balance between security, functionality, speed, power consumption, and range - uses TI's CC1312R on both ends. To Samy's credit, I developed this after watching his OpenSesame hack half a decade ago.

Someone below is asking that the rolling code can't work the way its told here. As if the receiver accepts only the next code what will happen if the transmitter is out of range and someone presses the button of transmitter ? As now transmitter has moved ahead of receiver. Well the video lacks a few things here. Actually there is a synchronization counter C which gets increamented each time you press the key (of transmitter). Same way the receiver also stores the most recent validated synchronization counter it has received (N). Now when ever you press the key and send the pseudo-random number to the transmitter the transmitter also takes the synchronization counter C from transmitter (and to update itself will overwrite N with C). Now receiver will also produce the Cth code (corresponding to C i mean) and match with the code send by transmitter. There is also rolling window of acceptance for rolling codes say 100 or 1000 or whatever (depending upon which system you using for your garrage or car keys). Now also note that C-N

[@munny218]

nailed it ! Hacks and Security is best

[@Prateekch95]

It's all good and easy in theory, but difficult practically.

[@k-s-x]

The receiver saves the counter-value of the last accepted code (N). Would a simple check C>N not solve this issue? If the attacker sends a 9th code ("stolen") after the receiver has already received 10th code, it will fail than.

[@Prateekch95]

@@k-s-x N will never be greater than C, unless there is a cycle of codes (which I'm assuming there isn't). Remember that the attacker can not generate codes, he/she can only use the ones it stole. So the receiver will not update the sync code if there's a wrong code.

[@hacksandsecurity]

N will be always smaller than C ! N is the last code (sequence number) recevier has received but C is the last code key generated. How can reciever receive more codes than those genrated by the key itself ? The attacks can't send any pre used code ! and if the attacker sends code against 9th sequence and receiver also calculates for the 9th seqeuence ( receiver calculates its own code against C). prateek brother i know its hard practically but slowly with time due to automations and so much new devices coming in market its becoming easier. Especially RFID key making companies (for cars) should pay attention to it.

[@ginsederp]

A very secure way to prevent any of these from working would be to have the door opener send the current time, followed by the signature of the current time. The garage door compares the received time to make sure it is within a window of its own time, say within 10 seconds to account for drift, signs the received time with the same signing key, and compares the 2. If they are the same signature, the door opens.

[@Teh_Random_Canadian]

The way he stored the second code would still work. He would just have to add the current time into his injection which would not be hard to do.

[@ginsederp]

@@Teh_Random_Canadian ah, but a signature is not the same thing as a signing key. Substituting the timestamp (the thing that is being signed against) with another automatically makes the whole signal completely invalid, as even a single digit change in the timestamp would generate a completely different and seemingly random signature with no relation to the previous. These signatures work as a strong verification because the signature itself is useless on a different payload. The only way to spoof a signature, is to steal the signing key (also known as a signing secret), which usually means stealing the opener remote itself.

[@sumphatguy]

@@ginsederp I'm curious though about the rolling codes. How does the remote know whether or not to move onto the next sequence? In their example for jamming/recording, they said how the device would send out code 1, which gets jammed/recorded. Then, they would use the transmitter again to try and open the garage and send out code 2. If theoretically that first code never actually gets used, wouldn't the transmitter and the receiver be out of sync?

[@ginsederp]

@@sumphatguy I'm not that familiar with this, but I think one way of doing it is to jam the signal for 2 sequences. Upon pressing the open button a 2nd time, the interceptor would stop jamming and send the 1st sequence, thus keeping the 2nd sequence as a valid open sequence. To the victim, it would look like the door didn't get the signal the first time, and most people would just try pressing it once more. Since the interceptor is much faster than a human, sending the 1st signal would seem indistinguishable from the door responding directly to the remote.

[@keyhousesarajevo8581]

@@sumphatguy There is no sync really, the receiver gets a code, uses algorithm to calculate the seed and if the seed is correct it opens the door and then it blacklists that specific code. If it never received the first code then the code is not blacklisted but remote will blacklist it for itself (as to not send it again because it thinks it's already used) but the receiver is still accepting that code. So you can use the first code after a month and it would still work because receiver never got it and it will accept it.

[@pwnmeisterage]

Your garage door signal was drowned under the EM noise floor. ECM jamming is also "old" tech.

[@ScottsSynthStuff]

Re: rolling codes - not entirely correct. Yes, you could technically see a code, grab it, and emit a jamming signal. Then do it again, like you mentioned, to have a "future" code. However...the garage door openers have a window of (usually 10 or more) "future" codes that it will accept as valid in addition to the current code. Otherwise, if there were interference between the remote and the door, or the remote was pressed far away from the door, the two would be out of sequence, and you would have to reprogram the remote to the opener before it would work again. People would be annoyed and think it was broken. Let's say both the opener and the remote are on code N. You press the remote while at the grocery store. Now the opener is still on N, but the remote is on N+1. On the way home, your toddler presses the remote again. Now the remote is on N+2, but the opener is still on N. You get home, press the remote, but you're too far away, so it isn't received by the opener. The remote is on N+3, but the opener is still on N. So you pull up closer to the garage and press the remote again. The remote transmits N+3, the opener says, "yup, that's valid" and opens the door. But here's the important thing: The opener now says, "OK, I've missed a few presses, but I received N+3 as valid, so now THAT is the valid code. The old N, N+1 and N+2 will not be seen as valid." Both the remote and the opener switch to N+4. So in your situation, your future code would be "killed" as soon as the opener DID receive a valid code from the remote, which would be pretty much immediately, because the owner would want to get into his garage. Incidentally, this is also exactly how hotel locks work. The front desk encodes "room 302, rolling code 5" onto your card's magstripe. You insert the card into the door lock of room 302. The door lock says, "well, I'm still on code 4, but now I see a valid code 5, so I will disable code 4 and switch to code 5." Now all code 5 cards will open the door. As soon as another card is encoded for the room, it will receive code 6, which when used in the lock, will disable code 5 and switch the lock to code 6.

[@icarusswitkes986]

gsmac1969 cool

[@OfTheKingOfTheGods]

@@icarusswitkes986 So I understand the idea that using a future code voids all previous codes, but in the video he mentions that the jammer device records code N and code N+1. , but sends code N after receiving N+1. so the jammer now controls N+1, receiver is on N+1, car is on N+2. The key detail is that the jammer sends the first signal after receiving the second so it still contains a valid future code of N+1.

[@Johnny.Fedora]

To this day, my building has the most primitive remote system for the garage (the system is quite old). I bought several remotes on Amazon, and they all worked fine when set. However, one came out of the box with the DIP switches already set in the up-down-up-down-... pattern, and worked without being set. RIGHT OUT OF THE BOX, it would open the garage gate. And yet, it's hard to get anyone to care or understand, because condo managers and board members tend to be low-tech folks. Aside from the inherently poor security, the code hasn't been changed for over 20 years. I realize how complicated that might be for everyone, but folks stealing airbags and catalytic converters often have it figured out (and no, camera surveillance, in practice, is not the cure-all).

the wild bit is that the de Bruijn sequence is not the shortest possible the shortest possible arrangenents are called superpermutations, and while the length of the 8-bit superperm isn't known, 4-chan has found the formula which can predict this length very accurately, which then allows computers to directly attack perms at that length and we should soon know the 8-bit superperm, which is somewhere around half the length of the de Bruijn sequence. It's called the Haruhi problem and the solution is the Haruhi theorem. In fact, the superperm is so efficient that it becomes possible to crack the rolling code opener with the superperm as well.

Fixed code systems are very easy to hack if you can get your hands on that particular kind of opener. Just build a binary counter one bit longer than the system, port the counter MSBs into the dip switch settings, and port the counter LSB to the "pushbutton". Then give your counter a square wave and let it count.

Garage door openers operate around 310 to 320 megacycles. It is laughably simple to open garage doors. I always shut the power off to my garage doors at night or when at home. I also latch the mechanical sliding lock as well. What prompted me to start doing this was a walkie talkie from a nearby mine that I took home by accident, opened th garages door when I hit the emergency tone. It was completely by an accident that I found out. I was going to go return the walkie talkie to the mine and I called on the walkie talkie. I talked to the mining authority and when I was going to shut down the walkie talkie I hit the emergency tone and the door opened. I switched the walkie talkie to low and it still worked. After that, I started powering down the garage door openers at night and when I am home. I do not trust the opener at all.

Easy way to hacker-proof an old 8 bit garage door opener: Use a remote lamp switch to power the opener. A local home supply store had two types, one with a 80 ft and another with a 140 ft range. The current ratings were large enough for a 1/2 HP opener motor but normally the relay in the remote controller will not make or break the motor current; only carry the motor current. One remote for each can be used if more than one garage door. Another way is a WiFi outlet controlled with a smartphone but this is more cumbersome to use.
