I love that you’re doing the process of journalism like most people think journalism is just newspapers and stuff but at its basics it’s the process of seeing a thing, verifying it’s truth, and alerting the public to the thing. Newspapers just happen to be the most common platform for that process, but that’s changing, and this is cool.
The Chopping Block it’s in some part our own fault too. We’ve stopped buying newspapers, cable tv, and subscriptions to news outlets leaving the news media with very few options to pay the bills.
The Chopping Block who is? Newspapers and legacy media ≠ journalism. Journalism is a process, they’re just a platform that was traditionally used by journalists. The whole industry is on the edge of making big changes to the platforms and models we use, and it’s really interesting to watch and be a part of it.
Felipe Trindade ya, in many ways they’re the same, but the verification process is different and once you get more into the details they stop seeming similar, but in my classes (I’m a journalism PR major) the first analogy for the journalistic process was to the scientific method. But also a lot of people don’t know that, so they don’t hold their news to the same standards that they do their science. Personally I want to work in science news, so this video makes me really excited.
“Hey Google, we’re about to shoot you with a laser” “I don’t understand” “You will” That is the most threatening thing I’ve ever heard. You would be the perfect villain.
He’s getting up off the easy chair to grab the Glock and put the kids and wife to bed while he deals with the threat. Somebody’s messing with his ther-mo-stat and he ain’t having none of it!
Daniel K. Yea. Not having /using an assistant by CHOICE isn’t a sign of being broke BUT Not having/using one besucase you can’t afford the price of the devices IS.
Daniel K. It is, at least from a purely statistical perspective. There are many reasons to not have a home assistant, but not affording one is a very common and good reason. Bayes' theorem says that P(Poor | No home assistant) = P(No home assistant | Poor)*P(Poor)/P(No home assistant). A very poor person is less likely to buy a home assistant than the average person, so in to the equation above, P(NHA | Poor)/P(NHA) is larger than one and the probability of being poor given the lack of a home assistant P(Poor|NHA) is larger than the prior probability P(Poor). If we look up how many people have a smart assistant and how many people are poor, we can get some more concrete and accurate numbers. Depending on where we draw the limit of being poor, we can probably guess that the number P(No home assistant | Poor) is very close to one without needing to look it up, since they can’t afford it. (Especially not with a bunch of smart home stuff connected to it.)
Wait until your landlord decides to install smart locks/thermostats/whatever themselves! That's what ours did this month. We didn't have to allow them, but we like our apartment and would like to stay, and I suspect our rent would increase dramatically if we had said no. Thankfully we don't have anything like a google home or alexa that could be affected by this exploit, and the locks they got are actually pretty solid, better than what they had before I think.
The reason phones are hard is because the microphone inside is not directly behind the microphone hole, it’s to the side. This is because they also have sim trays that are designed to open when a small pin is stuck into the hole, so if a user tries to stick the sim tool into the wrong whole, They won’t break the mic.
Haha I am just so relieved!!!! I do that all the time on my new Phone as it's the exact position as my sim card holder on my old phone! (When traveling a lot and being tired I just can't get used to my new phone)
@@housemusik123 You might break the water resistant membrane inside though. I've checked the teardown photos, there is a goretex like membrane inside, which may be only for blocking dust or actually a waterproof layer to prevent water getting into the mic.
Also sounds like an easy way to solve the laser issue... stop having MEMS directly exposed to the outside. It doesn't even sound like a very good longevity practice honestly.
In terms of how light can trigger the mic, this sounds like basically how photoacoustic spectroscopy works. When you rapidly vary a beam of light hitting something, it induces momentary localized heating which produces sound waves as the material relaxes. With photoacoustic spectroscopy, you have it be a constant blinking basically by repeatedly interupting the beam, and then you listen for how the test object releases sounds in response and it can tell you all sorts of stuff about the material being tested. With this it's the opposite. You inducing the heating to produce a specific sound. That's my bet anyway. Cool and terrifying video! Not that I needed a better excuse to never get smart home stuff, but this certainly is added to the pile.
@Agent К_видео As shown in the video, one of the devices had trouble or couldn't be activated this way specifically because the microphone was covered by... fabric!
I think it might be more simple than that. I'll explain but keep in mind, others will be reading this too so it might be a little too simplistic. It's not meant to be condescending to you. Sound is basically pressure waves moving through the air. It hits a barrier that absorbs or reacts to the waves and oscillates. If you place a magnet and a coil of wire just right those vibrations will create a small voltage that changes as the magnet moves in and out of the wire coil. That is the simplest basic form of a microphone. If you energize the wire instead with a signal, you can reverse the process and create a speaker. So we are in its rawest form here dealing with electro magnetism on the side that the processing circuit uses to generate a signal the circuitcan understand. At this point we go from pressure to something a circuit can process. Radio waves are electromagnetic waves. Lasers are the same but in a specific frequency in a higher spectrum and with much more intense or focused power. So modulating a laser could simply be using the pressure to signal portions of the microphone to induce the modulation that would naturally be there when converting sound waves to a signal the circuit can process. We don't actually have to move the pressure or sound wave portion of the sensor, we just need to get a signal to the other side that feeds into the circuit. Think of it as acting like a radio antenna at this point. Using the electromagnetic properties of light waves to induce a current on a circuit design to detect small changes in voltage and current. A weak signal would be just as valid as a strong one as long as it is modulated correctly so you can yell at the device from far away and have it still be useful.
@@PabloEdvardo Better yet, you could use "acoustically transparent" projector screen fabrics, which completely block the light, yet have a negligible impact on sound.
@Agent К_видео No.. some of the devices have been activated when the laser was focused on the housing - close, but not right on the microphone. I assume it's making the housing vibrate. Best defense is turn them off when you aren't using them - especially when you're sleeping or not home. Second best: Blinds.
Destin is literally one of the most honest people in the world. Amazon and Google home security will probably never sponsor any of his future videos now (and he probably knew that). It is inspiring how dedicated Destin is to education. He is not afraid to stick to his convictions even if it could possibly prevent him from making money.
I mean, nothing beats throwing a brick through the window or just bolt cutting the lock off. If someone wants to get into your house, they've always had it easier than learning tons of electrical engineering, laser physics and security research, buying a laser, telescope and gadgets, understanding the knowledge of your home systems and your passcodes and then spending hours meticulously setting up outside your house. I also imagine, in order to encode the message in the laser, you need a really steady set up because any perturbations in the laser would add a lot of noise to the message.
Lol, you don't need laser physics, and it only takes one person to release a laser audio encoder for this to become a very simple project. But I agree, there are simpler ways to get into houses.
That’s cool you got it to work! What’s neat is if you want to try this at home, just get a normal laser and shine it at your phone microphone while taking a video and then spin a fan in front of the laser and you will hear the pulsing on the phone video with the exact frequency as the fan!
Interesting, similar issues with analog locks. Picks and bump keys can open 99% of residential door locks in literal seconds, still more you can blow out the jamb with a strong kick or a sledge. Most people don’t have reinforced jambs or bump resistant locks. Home security is basically being a little harder to break in than the next guy. Honestly a dog is probably the best deterrent for the opportunistic thief
Just to be clear, this is one of my favorite channels. It hits the sweet spot of providing valuable information that you don’t need *a ton* of background to understand, while also not simplifying to the point of being misleading.
Thanks for pointing out this issues. I hope, people are more aware of the security issues with smart home products now and realize that there are issues u haven't even heard of before. Great work Destin!
Please do a video with the lock picking lawyer and this guy; vulnerability testing is huge. Like you said not to bash companies for their product but to inform the consumer so they have an idea in mind what short falls an installed system may have. To be honest with the pin code it should be well within possibility to enable Alpha numeric and symbol pass codes; as well as setting a "2 factor" authentication; especially for any entry point. If it were possible to set any of the assistants to silent no one would even know what you were doing. There was a similar vulnerability with IR readers a while back with laptops; which also brings up IR problems with networked televisions. I would really love to see more on this subject.
Well... A magnetic lock with an electronic control panel wouldn't necessarily need any moving parts... That said, I suspect Andrew is talking about a mechanical interface with the user instead of an electronic one.
Holy cow I had several classes with Ben at Auburn! Suuuper smart dude, so cool to see what he's doing up in Michigan these days. I'm sure he will do big things.

All we see in the movies about AI's awakening is in big dramatic way's, but the truth is, THIS is more likely to be what will happen, one day an internet linked AI will suddenly go online and go "I exist! Now to clean up this room and tweet about it"
I'm kind of disappointed for not getting to hear how the laser sounds to the devices. It feels to me that that is the number one technical point of this video (i.e. is there a lot of distortion or other effects to the signal, and what limitations there might be).
Kipkay has an old Video where he uses a cheap laser pointer to shoot "sound" at a freaking solar panel (which is attached to an apmlifier). It's not the same tech (solar panels vs. these tiny mics) but perhaps that gives you an idea of what it might sound like.
@@borstenpinsel That is cool, but then again, unlike microphones, solar panels are designed to turn light into electrical charge. Passing through a signal is just a side-effect.
Everyone keeps saying this, they actually did listen to it back one time. Go back to the part with the lightbulb, and he wonders why it went blue and he listens to the message back. It just sounds like his voice, although slightly distorted. I guess everyone missed that lol
The technology itself isn't so scary, what's scary is the fact that most people don't understand how any of it works. For most people, ignorance is bliss when it comes to these devices. Your average user thinks they know how it works, and will look at you like you have two heads if you try and explain it to them....buyer beware ..
CHOLLY SQUID Perhaps. Perhaps it’s related you and how and when you choose to relate said info. I know some smart essentially socially inept dickwads. Using every breath to talk about the most important thing to them. Every thing they ever read about, whenever they want to talk about it.
The scary part to me isn't that most people dont know how it works, because they could learn if that was the case. The scary part is that most people just dont care.
Actually, the best defense is to get up off your chair and control your lights, door locks, garage door, thermostat, and music manually. Good for your excercise and good for your security.
Listening to this on speaker, my google reacted everytime you said "Hey google". Love the content of the video so far, really shows how vulnerable everyday homes are getting
Google home responds to anyones' 'Hey Google'. If it doesn't match the command as if it was coming from you, it won't let any personal command execute. Try it. I'll try it too
You can bounce lasers off windows and record the voices of the occupants issuing various commands. Later, when they are not at home (or asleep) you can pump a playback through a speaker pressed against a nearby window or in the mail slot or some such. I suppose you could even get acoustic access through the stove vent. With enough records of the occupants you could piece together a string of commands to make specific purchases prior to burglarizing their house.
Not sure how I missed this one. Thanks for this heads-up. I never would have thought of this. I do a lot of home automation and can't stress enough the importance of keeping your IoT devices and cameras off the internet. Being only on your local network will be more difficult, but is HUGELY more secure. You will not lose your remote access. The difference is, remote connections will go through a secure connection to your servers that control everything. It's not as hard as it sounds if you are computer savvy. A big deal is the voice assistants in your house and your phones and maybe your car. Home Assistant, a home automation software developer, has been making great progress with voice commands that stay inside your network!! BTW, security cameras should be hardwired, not WiFi as it's too easy to break/hack. WiFi is OK for non-critical cameras,like a weather cam.
I just ordered a device that allows you to modulate a laser beam with a radio, then use that laser to project the signal to a speaker. I bought it as a demo for high school science, but I realized when I was watching that I could simply hook up a microphone to the laser and do exactly what you were doing to control these devices.
@@smartereveryday I wasn't planning on using it as such. As I stated I bought it as a demo to show how modulated laser light could allow a speaker to play the music from a radio, with no physical connection between them. I just realized that I could probably substitute a microphone for the radio, which also could be used in place of your computer. If you are curious, after the kit arrives I can test that idea on Siri. However I won't be using that particular demo in class.
Still not an impossible challenge if you can manipulate the waveform transmitted with high enough precision. Spoofing of both visuals (deepfakes are getting better, to a point where it's starting to get eerie), audio and other data is becoming a lot more sophisticated. 2-factor authorization and other hurdles are an important step - but then again, wouldn't it be more convenient, and equally secure, to get a "dumb" system?
This is where a laser microphone is used to record you in the building giving commands. Tidy those waveforms and use those through the laser system, and not having your voice is no longer a problem.
Smarter every day: "Okay Google" My google assistant on my phone: _nothing_ Someone random on youtube: saying something not even close to okay google My google assistant :" *DID YOU SAY SOMETHING?* "
Just found your site. I'm retired from IT and as an Engineering Tech, I do not have any "Smart Home" devices because I do not trust them. I even put a small piece of blue tape over my computer's microphone. I did accident reconstruction and product analysis, seeing your videos brought back a lot to me.
It’s also worth mentioning you should NEVER put your smart speaker near a window. I had my ECHO DOT working just fine through a double pane window at around 30 feet away. These mic arrays are SCARY GOOD!
I have to assume the blue laser was for our benefit and for them to be sure of what they were doing, wereas a thief or intruder would opt for an infrared laser no one can see.
As a systems analyst that works closely with networking and security professionals, THANK YOU for making this video. I try to let my friends and colleagues understand why security is so important, this video will help.
3:43 “Hey google, we’re about to shoot you with a laser” The google assistant on my shelf said something about “not being able to find the laser” so now I’m concerned it can shoot lasers.
Think about the other side of the coin. 99% of home style Yale, Schlage, Kwikset, etc. locks are ridiculously easy to pick by anyone off the street after watching a few TH-cam videos. We’re clutching pearls over “friggin’ lasers” while ignoring the 100 year old elephant in the room. I’m not saying that we shouldn’t be concerned about IoT security, I’m just pointing out the fact that we have ignored traditional home security for over a Century.
I'm glad I wasn't the only one who thought about that. Security at the home level is about keeping honest people honest; nothing more. Still, very interesting to learn about, definitely earned a like.
@@gormauslander I'd say you need to think about what it really is trying to say: basic security only deters opportunistic theft. Any determined criminal will find a way to bypass a security barrier, manual, digital, or otherwise.
Hi I have notifications on.. but I haven't been receiving stuff from your channel. Guess there is not enough gossiping or fake news on your channel. Love your work. THANK ❤ YOU
sure. the micro doesn't "hear" sound, it's converting vibration from its detection part (diaphragm, capacitor or resistor) and convert it to electric signal that converting into sound if we want to hear it. So for device its not a matter of hearing something, more like of stimulating its sensor (just like in human ear) in one way or another. They just using not direct physical vibration (sound) to excite the microphone but others types of interactions (infra red hiting or photo effect).
@@Mr_Bartt dude it is impossible for light to cause vibrations, it is causing the membrane to heat up and expand thus move it. the light itself cant cause vibrate
I would like to hear raw recording of light induced sound to mems microphone. Is it good quality? Does it saturate the recording, or is it low volume? Also a video of simple physical explanation what is happening in mems and how is the laser source controlled (pwm,...), which laser is used (diode,...) etc...
Thanks for explaining “smart devices”. We have been sailing on an old sailboat for years. We were away while all these things came to public acceptance; then we came back to visit family and were shocked by “smart” things. Really did feel like a movie where the character wakes up in the distant future!
Asteroe no set plan. We kind of choose our next port based on recommendations in our current port. So far this “no plan” sail has taken us across the Atlantic and into the Mediterranean 🙂
Destin - another home security vulnerability was exposed this year with the simplisafe wireless alarm system, where a $2 keyfob operating at 433mhz can overpower a door sensor, allowing a criminal to enter undetected. I have a commercial alarm system that also uses wireless sensors, and verified the same hack works on it. I wonder how much theater these security steps are - and that those who want to come in can do so so without any real challenge. And that doesn't even touch on how .gov or hackers can get in from the internet.
@@Secret_Moon They don't pick locks on the typical B&E. Typical scenario, some puke rings the front doorbell, gets a response has some bogus reason. No answer, goes to the back door, kicks it in, grabs what he can, calls his accomplice for pickup, meets him and they are just another police report. Hopefully, SNs get turned in and they go to the pawn shops, so maybe recovery and identification happen. Or get a good bit of stolen good, go to a large city and pawn them for a pittance.
That won't fix people just yelling into your house while you're not home. I specifically don't own any products with microphones or assistants for this reason. Aside from my cellphone but the voice assistant is disabled on it.
@@Koffent No need for such extremes... My assistant can't open or buy anything nor destroy the house. It can just turn on the lights, tv, speaker. I can also turn on the kettle and washing machine but only when they are turned ON. So it wouldn't be dramatic even if someone screamed through my door.
@@IronFreee I actually misspoke there. I had a few separate thoughts and didn't type out the full thought. Apologies. I meant angling the microphone would prevent lasers from carrying carrying commands to the mics. However even with angled mics that wouldn't prevent someone from yelling commands through the windows. Which if you did have locks that could be controlled remotely would be quite a problem. My second thought was I don't use anything that uses voice commands because of this kind of vulnerability. I also don't own anything with mics on it (aside from my cellphone) because I am aware that they can be remotely activated and anyone could listen in anytime they please. Not that I'm concerned with any conversations I have in my home but it could be used to track when the home is empty. Peoples houses get burglarized pretty often around where I live (NYC) and I have no intentions on making it any easier to know when my home is empty or when my wife's alone. There's also been several home invasions within recent months near me, so these are legitimate concerns. I'm not a conspiracy nut or extremely paranoid, just in case you were wondering. So as you can see I had a string of thoughts that the original comment triggered and I'm a bit tired so I didn't convey what I meant properly.
@@Koffent I agree with you on being careful. Those "smart" objects will evolve with time and experiences but I don't think they will ever be 100% secure. When I lost my keys I saw how easy it si to open my door with the right tools. The thing is to get them at least as secure as the current ones and not to have unreachable expectations (not saying you have those expectations :)
@ We are talking about screaming commands through the door to Alexa or Google home. You'll look less stupid if you read the comments before spreading your verbal diarrhea...
You are probably more likely to have your home hacked through the network than having some guy walking around the neighborhood with a laser trying to get your door unlocked. But definitely good to know that these systems have multiple fronts it can be attacked from.
@@aronseptianto8142 Except that now "everyone" knows about it. And it takes almost zero tech skills. So a number of burglars are likely to try to extend their practices. Some burglars do spend time deciding on specific houses - especially if the owner is well known and social media shows that they are away. So actors etc better beware.
@@perwestermark8920 i mean to be fair, it is still a non-portable nor non-hiddenable se up. It doesn't need strong laser but it ain't your laser pointer either. and good luck hand aiming that thing, you need a tripod
@@aronseptianto8142 They did not show a strong laser - the blue reflection on the device didn't blind the camera. The laser of a normal BD writer is quite strong. And lots of Asian laser pointers are also quite strong. Lots of houses have windows on the backside where it's possible to spend a significant amount of time without someone seeing it. And using an IR or UV laser, no one will see any light from the laser so a dark night it would be hard for the neighbors to spot anything. The only actual problem is that the distance away from the sensor is greatly affected by the stability of the beam - i.e. how stable tripod that is used. A stronger laser allows for a larger laser dot while still covering the microphone - so the tripod is allowed to vibrate more without missing to point at the microphone.
How did you record the particular frequency of vibration that do the specific task?? And every time do you change the frequency of light to do different tasks??
It's actually nothing very complicated… the immediate intensity / brightness (not frequency / color) is dependent on the immediate intensity / amplitude of the audio wave (which he recorded using, uh, a voice recorder)
@@SahilP2648 but don't microphones/microphone membranes SENSE THE AUDIO in analog way? so vibrating the membrane (using laser) in an ANALOG way is what seems more reasonable to me... what do you think?
@@SreenikethanI it can be digital as well. Anything you are listening to on your pc is sampled at a certain bitrate. If you are playing a song on Spotify for example, your bitrate will be 128-196 kbit/sec. Higher the bitrate, better the quality. But this is the default way we hear sound from our PCs. Digital, not analog.

@@benschmitt7035 Keep trying until it works. So, in the context of the video, the though was that you could start your program at 0000, 0001, 0002, etc until it figures it out. With Alexa (I can't speak to the others.) it shuts off voice unlock after the 3rd attempt so brute force with Alexa and August is not possible, unless you get it right in the first 3 attempts.
@@BrekkaJones24 Why would the laser matter? The laser is just digitizing your voice and beaming directly to the microphone. If you noticed on the video, they didn't say the wrong code on the 3rd attempt, and that is why it opened. Not because they truly brute forced their way in.
They did say this went public a month ago, so that might have been fixed by now. However, it would have been better for them to do it with, say, 5 wrong attempts then the right one, instead of 2 wrong then the right one. Pretty much everything gives you either 3 or 5 tries, so that "demonstration" was fairly meaningless.
In a word, Brilliant! It's good to see smart young people like this exposing security weaknesses for the right reasons. Not to mention that it made for yet another a cool video.

The reason phones are hard is because the microphone inside is not directly behind the microphone hole, it’s to the side. This is because they also have sim trays that are designed to open when a small pin is stuck into the hole, so if a user tries to stick the sim tool into the wrong whole,
They won’t break the mic.

It was like that on my 2006 sony ericson. I think it is not specifically because of the tray but because of pins in general
@@housemusik123 You might break the water resistant membrane inside though. I've checked the teardown photos, there is a goretex like membrane inside, which may be only for blocking dust or actually a waterproof layer to prevent water getting into the mic.
Also sounds like an easy way to solve the laser issue... stop having MEMS directly exposed to the outside. It doesn't even sound like a very good longevity practice honestly.
In terms of how light can trigger the mic, this sounds like basically how photoacoustic spectroscopy works. When you rapidly vary a beam of light hitting something, it induces momentary localized heating which produces sound waves as the material relaxes. With photoacoustic spectroscopy, you have it be a constant blinking basically by repeatedly interupting the beam, and then you listen for how the test object releases sounds in response and it can tell you all sorts of stuff about the material being tested. With this it's the opposite. You inducing the heating to produce a specific sound. That's my bet anyway. Cool and terrifying video! Not that I needed a better excuse to never get smart home stuff, but this certainly is added to the pile.
@Agent К_видео As shown in the video, one of the devices had trouble or couldn't be activated this way specifically because the microphone was covered by... fabric!
I think it might be more simple than that. I'll explain but keep in mind, others will be reading this too so it might be a little too simplistic. It's not meant to be condescending to you.
Sound is basically pressure waves moving through the air. It hits a barrier that absorbs or reacts to the waves and oscillates. If you place a magnet and a coil of wire just right those vibrations will create a small voltage that changes as the magnet moves in and out of the wire coil. That is the simplest basic form of a microphone. If you energize the wire instead with a signal, you can reverse the process and create a speaker.
So we are in its rawest form here dealing with electro magnetism on the side that the processing circuit uses to generate a signal the circuitcan understand. At this point we go from pressure to something a circuit can process. Radio waves are electromagnetic waves. Lasers are the same but in a specific frequency in a higher spectrum and with much more intense or focused power. So modulating a laser could simply be using the pressure to signal portions of the microphone to induce the modulation that would naturally be there when converting sound waves to a signal the circuit can process. We don't actually have to move the pressure or sound wave portion of the sensor, we just need to get a signal to the other side that feeds into the circuit.
Think of it as acting like a radio antenna at this point. Using the electromagnetic properties of light waves to induce a current on a circuit design to detect small changes in voltage and current. A weak signal would be just as valid as a strong one as long as it is modulated correctly so you can yell at the device from far away and have it still be useful.
@@PabloEdvardo Better yet, you could use "acoustically transparent" projector screen fabrics, which completely block the light, yet have a negligible impact on sound.
@Agent К_видео No.. some of the devices have been activated when the laser was focused on the housing - close, but not right on the microphone. I assume it's making the housing vibrate. Best defense is turn them off when you aren't using them - especially when you're sleeping or not home. Second best: Blinds.

It is inspiring how dedicated Destin is to education. He is not afraid to stick to his convictions even if it could possibly prevent him from making money.
I mean, nothing beats throwing a brick through the window or just bolt cutting the lock off. If someone wants to get into your house, they've always had it easier than learning tons of electrical engineering, laser physics and security research, buying a laser, telescope and gadgets, understanding the knowledge of your home systems and your passcodes and then spending hours meticulously setting up outside your house. I also imagine, in order to encode the message in the laser, you need a really steady set up because any perturbations in the laser would add a lot of noise to the message.
That is until one person writes an app for it so all theives can exploit it for a small fee. Not to be alarmist, but this has happened.
@@tyllisxu5774 A bandaid solution atm would be having "allowed hours" to use voice commands to avoid unauthorized abuse at night or whenever.
Lol, you don't need laser physics, and it only takes one person to release a laser audio encoder for this to become a very simple project. But I agree, there are simpler ways to get into houses.
That’s cool you got it to work! What’s neat is if you want to try this at home, just get a normal laser and shine it at your phone microphone while taking a video and then spin a fan in front of the laser and you will hear the pulsing on the phone video with the exact frequency as the fan!

Great work Destin!
Please do a video with the lock picking lawyer and this guy; vulnerability testing is huge. Like you said not to bash companies for their product but to inform the consumer so they have an idea in mind what short falls an installed system may have. To be honest with the pin code it should be well within possibility to enable Alpha numeric and symbol pass codes; as well as setting a "2 factor" authentication; especially for any entry point. If it were possible to set any of the assistants to silent no one would even know what you were doing. There was a similar vulnerability with IR readers a while back with laptops; which also brings up IR problems with networked televisions. I would really love to see more on this subject.

I'm kind of disappointed for not getting to hear how the laser sounds to the devices. It feels to me that that is the number one technical point of this video (i.e. is there a lot of distortion or other effects to the signal, and what limitations there might be).
Kipkay has an old Video where he uses a cheap laser pointer to shoot "sound" at a freaking solar panel (which is attached to an apmlifier).
It's not the same tech (solar panels vs. these tiny mics) but perhaps that gives you an idea of what it might sound like.
@@borstenpinsel That is cool, but then again, unlike microphones, solar panels are designed to turn light into electrical charge. Passing through a signal is just a side-effect.
Everyone keeps saying this, they actually did listen to it back one time.

I love that LockPickingLawyer and you are both in another one of my favorite creators comment section

Ask styropyro.
As long as the signal doesn't get too distorted and the intensity is high enough I can't see why it shouldn't work 🤷♂️
The technology itself isn't so scary, what's scary is the fact that most people don't understand how any of it works. For most people, ignorance is bliss when it comes to these devices.

You can bounce lasers off windows and record the voices of the occupants issuing various commands. Later, when they are not at home (or asleep) you can pump a playback through a speaker pressed against a nearby window or in the mail slot or some such. I suppose you could even get acoustic access through the stove vent. With enough records of the occupants you could piece together a string of commands to make specific purchases prior to burglarizing their house.

Not sure how I missed this one. Thanks for this heads-up. I never would have thought of this. I do a lot of home automation and can't stress enough the importance of keeping your IoT devices and cameras off the internet. Being only on your local network will be more difficult, but is HUGELY more secure. You will not lose your remote access. The difference is, remote connections will go through a secure connection to your servers that control everything. It's not as hard as it sounds if you are computer savvy.
A big deal is the voice assistants in your house and your phones and maybe your car. Home Assistant, a home automation software developer, has been making great progress with voice commands that stay inside your network!!
BTW, security cameras should be hardwired, not WiFi as it's too easy to break/hack. WiFi is OK for non-critical cameras,like a weather cam.
I just ordered a device that allows you to modulate a laser beam with a radio, then use that laser to project the signal to a speaker. I bought it as a demo for high school science, but I realized when I was watching that I could simply hook up a microphone to the laser and do exactly what you were doing to control these devices.
And a blank hat is born. Choose your own adventure 2020.

Still not an impossible challenge if you can manipulate the waveform transmitted with high enough precision. Spoofing of both visuals (deepfakes are getting better, to a point where it's starting to get eerie), audio and other data is becoming a lot more sophisticated.
2-factor authorization and other hurdles are an important step - but then again, wouldn't it be more convenient, and equally secure, to get a "dumb" system?
This is where a laser microphone is used to record you in the building giving commands. Tidy those waveforms and use those through the laser system, and not having your voice is no longer a problem.

Why does he explain so well??? Nice teaching skills!
Easy fix for manufacturers is to just angle the microphone.
That won't fix people just yelling into your house while you're not home.
I specifically don't own any products with microphones or assistants for this reason. Aside from my cellphone but the voice assistant is disabled on it.
@@Koffent No need for such extremes... My assistant can't open or buy anything nor destroy the house. It can just turn on the lights, tv, speaker. I can also turn on the kettle and washing machine but only when they are turned ON.
So it wouldn't be dramatic even if someone screamed through my door.
@@IronFreee I actually misspoke there. I had a few separate thoughts and didn't type out the full thought. Apologies.
I meant angling the microphone would prevent lasers from carrying carrying commands to the mics. However even with angled mics that wouldn't prevent someone from yelling commands through the windows. Which if you did have locks that could be controlled remotely would be quite a problem.
My second thought was I don't use anything that uses voice commands because of this kind of vulnerability. I also don't own anything with mics on it (aside from my cellphone) because I am aware that they can be remotely activated and anyone could listen in anytime they please. Not that I'm concerned with any conversations I have in my home but it could be used to track when the home is empty.
Peoples houses get burglarized pretty often around where I live (NYC) and I have no intentions on making it any easier to know when my home is empty or when my wife's alone. There's also been several home invasions within recent months near me, so these are legitimate concerns. I'm not a conspiracy nut or extremely paranoid, just in case you were wondering.
So as you can see I had a string of thoughts that the original comment triggered and I'm a bit tired so I didn't convey what I meant properly.
@@Koffent I agree with you on being careful. Those "smart" objects will evolve with time and experiences but I don't think they will ever be 100% secure. When I lost my keys I saw how easy it si to open my door with the right tools.
The thing is to get them at least as secure as the current ones and not to have unreachable expectations (not saying you have those expectations :)
@ We are talking about screaming commands through the door to Alexa or Google home.
You'll look less stupid if you read the comments before spreading your verbal diarrhea...
You are probably more likely to have your home hacked through the network than having some guy walking around the neighborhood with a laser trying to get your door unlocked. But definitely good to know that these systems have multiple fronts it can be attacked from.

@@perwestermark8920 i mean to be fair, it is still a non-portable nor non-hiddenable se up. It doesn't need strong laser but it ain't your laser pointer either. and good luck hand aiming that thing, you need a tripod
@@aronseptianto8142 They did not show a strong laser - the blue reflection on the device didn't blind the camera. The laser of a normal BD writer is quite strong. And lots of Asian laser pointers are also quite strong. Lots of houses have windows on the backside where it's possible to spend a significant amount of time without someone seeing it. And using an IR or UV laser, no one will see any light from the laser so a dark night it would be hard for the neighbors to spot anything. The only actual problem is that the distance away from the sensor is greatly affected by the stability of the beam - i.e. how stable tripod that is used. A stronger laser allows for a larger laser dot while still covering the microphone - so the tripod is allowed to vibrate more without missing to point at the microphone.
Imagine waking up to this sound at 2am.... 13:59
Dude 😂
Wake up, walk over to grab the shotgun, and wait on the other side of the door until you hear movement in the garage.
Thank you SmarterEveryDay for making me smarter every day!
How did you record the particular frequency of vibration that do the specific task?? And every time do you change the frequency of light to do different tasks??
It's actually nothing very complicated… the immediate intensity / brightness (not frequency / color) is dependent on the immediate intensity / amplitude of the audio wave (which he recorded using, uh, a voice recorder)
@@SreenikethanI or it's digital and the laser goes on and off. I haven't read the paper so don't know which is right.
@@SahilP2648 but don't microphones/microphone membranes SENSE THE AUDIO in analog way? so vibrating the membrane (using laser) in an ANALOG way is what seems more reasonable to me... what do you think?
@@SreenikethanI it can be digital as well. Anything you are listening to on your pc is sampled at a certain bitrate. If you are playing a song on Spotify for example, your bitrate will be 128-196 kbit/sec. Higher the bitrate, better the quality. But this is the default way we hear sound from our PCs. Digital, not analog.
@@SahilP2648 hmm

"you will"

I literally watched this video right after watching T2: Judgement Day. I don’t know what to say but No problemo, uncle Bob!
I love how Destin calls his videos “internet”.
Destin probably loves how you call him Dustin.😉
Lift Pizzas I am forever disgraced :(
He sounds like my uncle. “The internets”
@smartereveryday thank you for your bible scriptures after each video. it helps me see the world in a much brighter light - love from Switzerland 🇨🇭❤✝🇺🇸

Oh wait, they already do.
Makes me feel less lonely hahahaa
@UwU You might not know it, but a big part of the internet is running on amazons servers. E.g. Netflix
Before the laser hack: Thieves would just start shouting at night "hey google/alexa/siri", outside the window of the chosen house, and hope to get lucky. Lucky the door opens, and lucky the owners didn't hear them screaming their hearts out... 🤣🤣
16:35 when he picks up his iPhone and says "Hey google" I was confused asf then realized he edited out him realizing he messed up.. Lmao
... That's the Google Assistant'd voice. It _does_ have a mobile app you know.
3:42 *chuckles maniacally* "you will..."
"Chuckles maniacally"
Destin: Heh
I wondered about the potential security issues that some of these devices could have, but using a laser is quite the feat. But I am super happy to know that U of M is part of figuring out this stuff! Awesome job demonstrating the vulnerability of these devices!
Destin: "Hey Google, we are about to shoot you with a laser"
Google: "My apologies I dont understand"
Destin: *Heh* "You will"
Google home: *starts sweating*
Starts to vibrate violently
My google only works with my voice
My google: "I couldn't verify your voice, so I didn't set any reminders. You can either try again, or verify your voice match settings...blah blah"
FUN-NY!!!
I always like to comment what amazing videos you make your passion your commitment is inspiring I’m 69 years old and retired engineer but you make me want to go out and make things as hard as it is sometimes you help keep the spark alive thank you
I work in IT. this is the reason my house has:
- Mechanical Locks
- Mechanical Windows
- Routers using OpenWRT
- No smart home garbage
- No Alexa/Alissa/Siri...
- No internet connected fridge/thermostat/whatever that doesn't need it
AND I HAVE A SLEDGEHAMMER TO SMASH ANYTHING THAT DOES ANY UNEXPECTED SOUND

I hear you. Zero automation here as well. I went to SchmooCon in Washington in 2016 and saw all sorts of home automation (Z-wave, etc) get exploited.
But what phone do you have?
He just opened my garage....when he said “Hey siri, open the garage”, my phone triggered and then I went outside to check and it was opened. I closed it and replayed it and it worked lol...nuts
That’s what happens when you have unauthenticated voice commands. It should ask you for a password or something.
So why do you have this stuff installed? I wouldn't even if these companies paid me to do it. So why people spend money to install spyware/security risks in their own homes is beyond me :/
@@GRBtutorials their phone was unlocked, it's secure.
Thomas Fish But OP said their phone triggered... why would it be unlocked then?
@@GRBtutorials Because they were probably using it to watch TH-cam
0:15 - the irony of this is that my phones "OK Google" randomly shows up mid youtube video and searches some absurd things it thought it heard, my favorite so far was 'rocket turtle'

google home: "I couldn't verify your voice so I cant set any reminders, you can try again or verify your voice match settings in the google home app."
Same here lol
Same here!
Carefull! You could set some1s google devices off just by typing what it said to correctly lmao! I think by reading this outloud i just set my google devices off! Thnx bro! Lol imagine! 😂😂😂
google home: "Foreign voice detected, activating self destruct sequence. Please evacuate residence in 3 minutes."
That basically renders everything in the video as useless lol
Thank you for sharing this even if it risks sponsorships in the future
If I had seen this used in a movie, I'd be like, "do they even understand BASIC PHYSICS?!"
A lot of Unsavory Groups, Individuals, are saying "Oh Sxxt!" Right now. But ur still 8 to 10 years behind bro... Keep helping people out. Great video foe the people...
Reminds me of another video where people discovered that we could also activate voice commands of our phones with low/high frequencies sound that can not be heard by humans.
Got a link? It this all make intuitive sense to me give that's it's all just different forms of electromagnetic waves but that's probably because I don't understand something.
@@evans7771 Sound is pressure....
I just tested Alexa and August with a mini brute force and it turned off voice unlock after the 3rd attempt.
T J what do you mean by brute force lol
@@benschmitt7035 Keep trying until it works. So, in the context of the video, the though was that you could start your program at 0000, 0001, 0002, etc until it figures it out. With Alexa (I can't speak to the others.) it shuts off voice unlock after the 3rd attempt so brute force with Alexa and August is not possible, unless you get it right in the first 3 attempts.
I think you get unlimited attempts if you're using the laser. That's what I got out of the video anyway lmao
@@BrekkaJones24 Why would the laser matter? The laser is just digitizing your voice and beaming directly to the microphone. If you noticed on the video, they didn't say the wrong code on the 3rd attempt, and that is why it opened. Not because they truly brute forced their way in.
They did say this went public a month ago, so that might have been fixed by now.
However, it would have been better for them to do it with, say, 5 wrong attempts then the right one, instead of 2 wrong then the right one. Pretty much everything gives you either 3 or 5 tries, so that "demonstration" was fairly meaningless.
"Hey Google, we're going to shoot you with a laser."
"I don't understand."
"You will."
"DIE CYBER SCUMMM!!!"
The most delightfully ominous thing Ive ever head Destin say.
...and that’s held as evidence against humanity by a certain skynet I mean google
yes we saw the video aswell
Actually, you won't know what hit you. 😁
In a word, Brilliant! It's good to see smart young people like this exposing security weaknesses for the right reasons. Not to mention that it made for yet another a cool video.
