This is not me giving you guys crap or anything, but just a friendly reminder to keep things civil here. Too often have I seen political conversations become political arguments.
Apparently I'm not being able to link the "two-character passwords x garage door openers" with the apparent fact Obama blamed Bush for his own mistakes. Care to explain?
+gotbletu Plan B 1. Buy up a pallet load of IM Me toys. 2. Post how to video on RU-vid 3. Sell IM Me toys for $150 each 4. Evil entrepreneur laugh (not that anyone would do this)
I have heard that excuse before, but on a buisness email account and not being careful with the password (It was a strong password), saying that nobody would exploit/hack/crack her email. Person was not careful enough and it got taken over by a spammer, which quickly got the email blacklisted and the provider quickly locked down the account after that. How the person got a hold of the account I don't know, but I suspect it was her doing emails over unencrypted wifi, hostile wifi or whatever, and sending the password in plain text instead of at least encrypted while sending the password that I said was the bare minimum. She/her husband failed to do something that easy, because the provider has step by step explanations how to set it up etc, which I told her about (She didn't have said phone with her or she was going home at that point, don't remember which). So no, that excuse is stupid. People will hack/crack wifi for several reasons, and the least worst one is perhaps those doing it do mess with the owner of the wifi, like pranks etc. Even though your family might not be affected directly, it can affect others or indirectly affect your family as well. Even people leeching internet can be annoying, what would it be like if police comes around because a hacker used the wifi for hacking purposes? Depends where you are situated what is likely or not, but being under suspicions of hacking is not a pleasant experience, then up it to suspicions of child pornography downloads! So even with a simple password like a single word or two (which is stupid because of dictionary attacks), it will be more secure than just numerals, which a lot of people try to do first on wifi's because of the WPS exploit. It could even be that the first password tried is actually 00000000, IIRC this correctly about WPS cracking.
The Aftermath NO but when a inquisitive mind finds some new information, at some point a decision is made of what you will doing with your findings. Do you keep the information secret and use it for your own or some other people/ organizations benefit, or do you inform the public, and make companies making millions /billions of dollars accountable for what they sell. Seems the ultra basic of any form of ethical hacking. Im clueless about hacking, just interested in circuit bending, and what what can be done with what is usually taught benign little toys. This one was meant to interface with the internet, so its a bit more sophisticated.
Ralph ralphson I agree that a decision is obviously formulated when the topic has potential issues. I just mean to suggest that tinkerers aren't typically doing this because they specifically want to be 'good' or 'evil' per se. It's merely down to the love of taking things apart and learning how they work at a fundamental level, most of the other stuff is an after thought.
If you still read the comments I wanted to thank you for the inspiration. After seeing your appsec 2016 talk I began working like a madman for an entire week and managed to make my own. I used rpitx with a raspberry pi 3, low pass filter and antenna to transmit frequencies and made a nifty python script to shoot out codes using the De Bruijn sequence. It takes 30 seconds but all things considered I’m very satisfied with that. Hearing that rusty old door rattle open was the proudest I’ve been in years. I was giddy for days. I’ve never done anything radio frequency or programming outside hello world’s. Maybe one day I can be like you, doing important projects and inspiring others. Thank you.
Hi can i contact u to further explanation? I've been programming a lot in python and raspberry pi but never with radio things and im lost. It'll be good to have buddy with same aspirations as mine.
You should make a video on this. Because I’ve looked up his code and it’s broken… so not sure how you managed to have his script converted to rpi and work
I can see your passion in doing this type of cool youth charitable educational content . I see that you currently do work with big brother/sister program. that's pretty awesome man ! I'm enjoy your videos man. I like the clean-up on this one .
I didn't use this to break into my house. I locked myself out by leaving my bump key resistant keys inside my house. My windows were all properly locked so I couldn't sneak in a window. I have a garage door opener in the house, but I don't have the actual opener. We never use our garage that way. I got into my new (to me) minivan which I have not programmed to open my garage door, to drive to my wife's place of work and get her key (30 minutes away). I start backing out and look up at the 3 buttons there. What are the chances it is programmed? I press the first button and my garage door opened. I need to replace my garage door opener...
I built something like this when I was 13 years old back in the early 90's using a bunch of relays and binary counters. Got the idea when opened up a universal remote, noticing only a few dip switches. It worked, but too far longer than 10 seconds! Used it only at a friends house (new sub division) because where I lived no one had automated garage doors. Cool seeing new and better ways of doing old things
Well at least those smart enough to pull this off have no reason to steal because electrical/software engineers make a hell of a lot. Then again if somebody where to sell this to a thief that has no idea how much it costs, they could ALSO make a hell of a lot of money.
I can't imagine it being very hard to make with some knowledge, it's just most knowledgable people are privileged and have the things necessary to make these, they have the availibility to learn and don't need to hack for malicious purposes
WhoWantsToKnow81 Ugh way too much. More than 50%. Drew the pixels from scratch, then fitting it into memory, getting it to animate while transmitting without interfering with the transmission...
Very interesting video (and the ones about the Master Combo lock too). I kind'a know about IT security, but had no idea how insecure the physical world is. Now I want to open all locks to understand how they work and verify all security related items in my life...
I think it is up to $229 now what do you think a good alternative would be? All these are under $40 but IDK if they will work. there is the Girl Gear SMS messenger,, the cyber gear SMS messenger M & M's messenger toys (they look like a rebranded version of the IM-me from the outside), or do we have to get some thing like the Cybiko (this thing is an actual computer for like $20 but no back light and the batteries are probably dead. if it has the cc11100 in it then this should be even more powerful than the IM-me and would give you the ability to save codes separately so you could like have a code for your garage, one for your gate, one for your work/s garage, one for your vacation home's gate and garage... ect there is like 1 gig of data on RAM and you can also add a one gig flash as well.) I'm thinking the Cybiko is the way to go as long as it being a computer doesn't make it harder to code with than the other toys though it might be fun to have just for the hell of it Also some site lists the radio frequency at 800-900 for the US version and 700-800ish for the EU version so we would have to look for the chip. post back if you check any out.
evilcanofdrpepper try to find the schematics to the IM-ME, or have somebody buy it and send it to bigclive and he will break it down.. then people can make their own
Why not thanks Reagan ? USA still uses cheques ... the most unsecure way to transfer money . There is way more secure ways to do that like personal transmitters that need to be 4-8 ins from reader it logs who is opening the gate ... you can hack them too but its way harder. Still tech cant replace real people as security measure ... a guard with shotgun that know everyone who can use garage stops any hacker
Pete Lind you're not wrong, 'thanks Reagan' just doesn't work as a Joke.

That is awesome. I always wanted to hack the garage opener when I was a kid, being inspired by the movies Home Alone, the robbers used some kind of device to hack the garage opener to a house. I didn't have any neighbors that garage openers though. But I had plenty of fun hacking home wireless phone frequencies to be able to listen to even the neighbors phone calls. I did this by modding some Radio Shack walkie talkies and even did it by modding an am/fm radio. I wouldn't know how it all works, but I was able to do it some how.
Often times, you could just use a baby monitor or walkie talkie that had the same carrier frequency of the more common wireless phones, such as 900mhz or 2.5ghz, and you would be able to listen to most wireless phone calls in range. It was a common practice by nosy people to use those in apartment complexes where you would often be close enough to receive multiple signals from different neighbors. Whenever I lived in an apartment complex, I used a landline only.
Tyee Cambrón He's not hacking the garage door opener. He's hacking a toy and using it to scan through the codes :: that is, literally giving every code possible.
For anyone doing their own math and getting confused about the numbers he got at around 10:00 - The de Bruijn is only responsible the reduction to 8.33% of the keyspace, and the removal of wait times reduces that to a half. Together, that gets 4.15%.
You would need an RF transmitter, but in that case, yes. I chose this device as (at the time) it was cheaper than an RPi, had a screen, backlight, keyboard, and all the RF functionality needed, so a pretty fun device to be playing with, but any capable microcontroller or machine with proper RF transmitter can perform this attack.
Is this attack still possible on garages which their opener does not have switches? Looking around for transmitters they all seem to have pretty decent range, am I going to end up opening my neighbors by accident?
Those are rolling code based garages and no, this attack will not open it, however I have developed a new attack that exploits rolling codes of those types of garages (as well as cars) -- details in my DEF CON 2015 talk/slides: samy.pl/defcon2015/
Funny you don't need the mattle toy....I build by my own a FM transmiter for my Electric guitar with $3, just 1 Rf transistor, the signal is pure, clean, with no armonics.... I made it for 91.5 Mhz and I can tell that is so easy open any fixed-code garage door of 300-400Mhz, just change the *Tank circuit oscillator* to a comercial frequency maybe 315 Mhz and after inject the 4096 or the "reduction" pass with a uC : 12 DIp switch example... 000000000001 000000000010 000000000011 .......................... Etc.
Just Awesome like every each of your videos. I tried to find the IM-ME on ebay and amazon without luck. Jus wanted to flash something :( Thanks and keep up the awesome work!
I'm guessing this only works because the receiver doesn't scramble the code every time the transmitter fails the "challenge". Maybe what they is need is some kind of really simple pseudorandom TOTP.
+Mike Trieu (MegasChara) Well, if the receiver scrambles the code at every attempt, your transmitter would be useless as well. Think about your neighbor unlocking his garage, which changes the code of your remote. What I'd do is that I'd put a "INCOMING CODE" code at the beginning and look for the password. If it fails, wait 5 seconds. This would easily eliminate almost all code cracking devices because It'd take too long time to complete.
+Anonymous User I've created a new device (after making this video) called RollJam which can attack rolling code garages and cars, not just fixed code garages like this, meaning *all* garages are susceptible to attack. You can learn more from my recent DEF CON talk (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-UNgvShN4USU.html) or more about it here (www.wired.com/2015/08/hackers-tiny-device-unlocks-cars-opens-garages/)
Sadly an im-me costs nearly as much as the hackRF One :( LUCKILY I already have an hackRF one! so I'm firing up Gnuradio! Cheers for the excellentness! :D
Just got through assembly/machine org at my university and it's awesome to be able to see how it can be applied. Absolutely incredible - love your work!
You can easily upgrade the security of these old garage door openers. Most wall switches have a "Lock" switch. Set it to "lock" which will prevent this hack from working, then install a low-cost Bluetooth receiver and open your garage using your phone. Because the Bluetooth receiver is wired in parallel to the wall switch it is not affected by the lock setting. Samy, I can send you one for free if you are willing to test it on an older opener (or see DIY video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-3rRAf1IaWpw.html). Thanks for this awesome video.
ahhhh! i had no idea garages used the shift register ...do all garages use that? when i was about 12 or so i tried to make something like this with a microcontroller kit from radioshack, but it would try every code on like a 6 DIP switch opener i connected it to. i had the proof of concept down but i didnt understand the coding well enough to get it to work. this is such a refined version and also lulz because of the girl's mattel toy. this is the perfect stuff for news headlines.. "hacker uses girl's mattel toy to open any garage in 10 seconds"
Is there anything special about the Texas Instrument chip or do you think it would be possible to use a 300-450 mhz chip like this www.maximintegrated.com/en/products/comms/wireless-rf/MAX1472.html. Thanks Samy for your research! I have learned a lot from your write ups and Github.
His logic was very sound. Didn't know you could brute force binary in a single string of characters that way, but some crazy genius mathematician figured that out, and I am sure it can be verified. Just with the idea, and a few important concepts this guy worked out in the video I am sure I could replicate this with an arduino.
D Clems I find it interesting that you can wreck anything with bit-shift registers like this. This technique could even be applied directly over data wires of certain security systems, safes, etc. to open them. This vulnerability is a pretty trivial one given the complexity, but could have some very serious consequences.
Hi Samy, You mentioned in your DEFCON talk that you would release details for RollJam, is this still going to happen? I'm trying to get a continuous transmission to work on the CC1101 (greater than 61 bytes FIFO supports, FSK key fob has approximately 1000 symbols). I'd love some guidance on the whole serial synchronous mode and using the CC1101 with Arduino in general. Great videos as usual
great Video! I feel like it's the 90's again. I used a de bruijn sequence to get answering machine remote access (they usually used 3-number pins transmitted via DTMF) somebody should test that with modern cellphone Mailboxes running in the operator networks. people often even don't know these can be accessed from any phone with a pin. if somebody wants to learn more: en.wikipedia.org/wiki/De_Bruijn_sequence
First of all, I really like your videos. Please keep on making them! I'm currently a first year electrical engineering student, and really want learn more about RF communication. Would you recommend buying a HackRF, or is a yard stick one enough for now?(I hear a lot of good things about the hackrf but it's a bit expensive).
One thing I want to ask out of curiosity: Would it be possible to run a custom programmed version of MS-DOS on one of these, or would it be impossible to fit it all on the built in storage?
This might work for a very specific type of garage receiver, as you did reverse engineering of your remote. But the RF protocol doesn't have standard and each manufacturer might implement his own protocol, by using different pulse length and bit representation (some even not using binary signal but ternary or...). Also not all remote have the same amount of bits. Your example will work mainly with the door using the same brand as your remote. A much more effective way to hack those door is to sniff the signal of the remote, as you can do as well with old car door. But still cool that you manage to hack yourself ;-)
This is really cool dude. I've read up quite a bit on the De Bruijn sequence since watching this video, and it's extremely interesting. Do you think you could provide more of a tutorial video on how to create one of these openers?
Awesome - surprising the manufactures of these systems don't put a little more thought into things. Love to get my hands one of these Mattel units to experiment with but haven't found one yet!
you said that the device you used can send and receive messages I belive. if that is so could it be possible to intercept the code that is being transmitted by the garage door opener when someone uses it, therefore getting the passcode? I realize it is much easier just waiting 10 seconds for the device to run all possible codes. I'm just curious =)
Chris, great question! You are absolutely correct. You can use the device to simply listen (RX) and obtain the code as soon as the legitimate user uses their own opener (assuming you're in wireless range).
I have a garage and i forgot the code, or, to be honest, nobody ever told me. As it is mine it is not illegal to hack-open it. I have a little device that opens it, but when i lose this, im screwed.
Came here because I started learning lock picking and wondered about combination locks. This channel is awesome! FYI, de Bruin is a Dutch family name which translates to the Brown. As for pronunciation, the English don't use ui and thus can't really pronounce it. Your best shot would be saying brune :P
i got a pre 1991 garage door opener,don;t work anymore...but teh opener works manually..i wonder if that can be hacked for "fun" and my cars...mercury grand marquis...do they all operate on 315 mhz even GMs thanks samy
Kenshin Himura I'd be less concerned about the person opening garage doors and be more concerned with the person sitting behind the garage door, waiting.
Does the remotes that came with the garage motor has a fixed algorithm or not fixed algorithms or I happen to have a myQ WiFi app, and I have several recent breaks ins, So I guess that this person has set the automatic opener on his iPhone or android. Is it too late to never able to change my WiFi password or even reset the motor? Can he remotely open my garage door on his Mobil phone? And if I was to 0:0:02 0:02 remove this communicator device, can his app works. No? Or if I have to buy another motor model without WiFi connection and he has a device to intercept my opening openings to configure my algorithm or s, can he then be able to figure out what’s the next rolling codes, or does he has a I’m me garage’s opener that can figure out the exact codes in 10 seconds? Or can’t he. I’m I safe with the new no WiFi motor. Or just stay with the one I have? Because it can be open or detect with proper equipment or device. 😢😂❤
The price of the IM-ME has skyrocketed to over $300 and the unit price of the chip seems to be from $600 to $1000+. I think i'll roll my own and offer it for free because fuck all that
Saw this after looking up if this was real in A Murder at the End of the World! Cool they used the exact same girl tech IM me! Love it

the wait time is for the end of the bit stream so it doesn't fail, basically when it repeats for time the button is held down it would be wrong that's why a wait time is for end of stream!
yo @Samy Kamkar I got some questions about garage doors. Its a bit complicated I own original pilot but I lose permission to the Gate from That I heard someone turned off ability of That remote by PC. Any ideas how to figure it out and open the Gate?
Do you remember last year when it can be said, ROLLJAM to do the smaller, as the size of a remote? Do you have any samples? Can be sold to Southeast Asian countries? I want to do this business! Are you interested in?
My garage door was hacked, waiting for help now! Completely ridiculous, maybe people need to get a job and buy their own shit! Here you are helping the crooks! Way to go kid!
i been thinking it would be nice to make a shield for arduino with lcd screen, keyboard, battery, buzzer and a RFchip. i would attach it on top of a DUE! if anyone like hte idea help me to make it a product
hey bud.. is there a chance you could write a programme to root android phones? the programmes I find are half baked at best and you seem like the type of person who could write a whole rooting, overclocking and ROM rebaking app in one.. I get that android is not rooted from the beginning and yes I could pay someone a few bucks to unlock the phone and all that.. but I want a fairly simple piece of software that can not only identify the phone, figure out what it needs to be rooted, root the phone and submit it up to an online database to allow others to use the the same methods for their own hardware, I mean once a particular phone is rooted, then it's fairly simple for the rest.. besides, once we own it, we can do what we like.. but I see you see with sight beyond sight and actually explain everything in a simple to follow explanation.
