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.
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.
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!
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!
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.
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.
“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.
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.
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!
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.
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.
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.
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
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
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 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!
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.
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.
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 🙂
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"
Will read paper to know what do you modulate with your voice command exactly: laser power? repetition rate? pulse width? beam diameter? That would help explain the physics behind the microphone providing a signal and tell laser types that can or cannot present such capability/threat. Bigger picture! Keep up the good work!!
@@Fellouche I had to google CW, doesn't that just mean that the laser is continuously 'on', but is continually modulated by whatever audio is presented? As you and Jeremy suggested, almost certainly AM.
Dan Nichols Right! They use commercial, Continuous Wave laser diodes (not pulsed lasers) whose output power baseline (here typically 5 mW for safety, up to 60 mW) is proportional to the direct current provided to the laser diode. I understand that an alternative current component (sine wave modulated by the voice command signal amplitude and frequency) is added to the diode current control to have the laser power vary according to voice amplitudes and frequencies in AM fashion. Interesting to read that aiming is helped with large beams but power density is decreased, limiting microphone response. Would be interesting to know how such MEMS microphones behave under pulsed laser beams with given peak power density and repetition rate. That would help identify whether it’s photoelectric or thermal effects at work here.
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.
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...
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.
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...
Hahahahahahahaha wow! So funny!!!!! Hahahahahaha you sure are clever! Hahahahahahahaha. Give this person a Grammy. Hahahahahahahahahaha! So original hahahahahahahaha................. 🙄
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.
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.
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.
Thanks for your videos. I have recently followed your channel and am really interested in all of your videos. Your videos are amazing, you explained me the complicated concepts in very simple ways to understand. This one opens my mind to know that the light can influence the microphone. It is a crazy thing.
7:09 You can transmit sound waves and radio waves through laser beams. We did it in a college physics class in the early to mid '90s using a "regular" microphone, I think it was an electret.
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!
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?* "
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
DUDE! PULL THE AUDIO FILES WITHIN THE ALEXA APP (it stores everything you say to it) See if you guys can analyze the ones from the laser. Maybe give us and idea as to what the echo is "hearing"
Echo "hears" similar stuff that you say out. Analog signal (may it be light in the laser or somebody's voice) has to be similar for getting a similar digital signal that the echo can understand and respond to. Otherwise, Siri/Alexa/whatever does not understand you and in some cases, do not recognize your voice pattern. But they demonstrated that the Assistant understands the command even when sent via laser. So, when you play back the recording, it should sound similar to the one that you hear when talking to the microphone. Probably with some quality loss (conversion from light to digital signal via a method that is not meant for it - the microphone is not meant for translating light signals).
Hi Destin, there is one more recent paper on hacking microphones, this time using inaudible ultrasound, self-demodulating into the sound in the air: Audio Hotspot Attack: An Attack on Voice Assistance Systems Using Directional Sound Beams and its Feasibility
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'
@SmarterEveryDay Destin, awesome video! I want you to know there's also a way to break in with inaudible frequency waves attacks, this is due to non-linearity properties on MEMs microphones. There are a lot of paper addressing this issue as well, maybe you could do a video about it. Looking foward to it!
@@smartereveryday Hello this is Destin, and what I have for you today is the first episode in a series on smart home devices. (I really hope you all read this in LPL's voice.)
Try these to find out how the laser is interacting with these devices: shoot a stethoscope with the laser-see if you can hear something. If so, it’s interacting thermally with the mic. Put a oscilloscope on different non-piezo MEMS devices (non energized) and see if an electrical current is generated.
@@Julia_Berrrlin As a physics student I can tell you it's really not that easy, we only think of light as waves in some circumstances, other times we think of it as many photons.(double slit experiment) Secondly, in this experiment they are modulating the intensity of the laser, not the frequency (the "waves").
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
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.
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
That was amazing to watch, my home is full of these gadgets and it's never once occurred to me there could be an issue like this with them. Let's hope your video gives these companies the kick up the backside they need to help improve the security of the devices.
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.
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... 🤣🤣

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.

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.
LPL is good at *picking* mechanical locks, not this type of thing. Hence the "P" in LPL.
@@xenonram true however he has shown some interesting ways into by passing electric locks
Andrew Delashaw how can a lock not be mechanical?
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.
yup and LPL covers using magnets in a few videos for by passing electric locks. If it secures a door or chain hes covered it or some variation.
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!
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.
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.

yep. It didn't set a reminder because it didn't recognize Destin's voice, but it did react to everything else.
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.

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 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!

Will read paper to know what do you modulate with your voice command exactly: laser power? repetition rate? pulse width? beam diameter? That would help explain the physics behind the microphone providing a signal and tell laser types that can or cannot present such capability/threat. Bigger picture! Keep up the good work!!
Guessing AM.
Jeremy Scofield Looking at laser setup, guessing CW and AM too.
@@Fellouche I had to google CW, doesn't that just mean that the laser is continuously 'on', but is continually modulated by whatever audio is presented? As you and Jeremy suggested, almost certainly AM.
Dan Nichols Right! They use commercial, Continuous Wave laser diodes (not pulsed lasers) whose output power baseline (here typically 5 mW for safety, up to 60 mW) is proportional to the direct current provided to the laser diode. I understand that an alternative current component (sine wave modulated by the voice command signal amplitude and frequency) is added to the diode current control to have the laser power vary according to voice amplitudes and frequencies in AM fashion. Interesting to read that aiming is helped with large beams but power density is decreased, limiting microphone response. Would be interesting to know how such MEMS microphones behave under pulsed laser beams with given peak power density and repetition rate. That would help identify whether it’s photoelectric or thermal effects at work here.
Thank you. I'm a disabled vet getting g my house set up for this. Gave me a lot to think about.
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.

@@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.

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.
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...

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.

PULL THE AUDIO FILES WITHIN THE ALEXA APP (it stores everything you say to it)
See if you guys can analyze the ones from the laser. Maybe give us and idea as to what the echo is "hearing"
Echo "hears" similar stuff that you say out. Analog signal (may it be light in the laser or somebody's voice) has to be similar for getting a similar digital signal that the echo can understand and respond to. Otherwise, Siri/Alexa/whatever does not understand you and in some cases, do not recognize your voice pattern. But they demonstrated that the Assistant understands the command even when sent via laser. So, when you play back the recording, it should sound similar to the one that you hear when talking to the microphone. Probably with some quality loss (conversion from light to digital signal via a method that is not meant for it - the microphone is not meant for translating light signals).

Lift Pizzas I am forever disgraced :(
He sounds like my uncle. “The internets”
@SmarterEveryDay Destin, awesome video! I want you to know there's also a way to break in with inaudible frequency waves attacks, this is due to non-linearity properties on MEMs microphones. There are a lot of paper addressing this issue as well, maybe you could do a video about it. Looking foward to it!

@@greybeard29 Nahh lock picking is just really cool :D
@@smartereveryday Hello this is Destin, and what I have for you today is the first episode in a series on smart home devices. (I really hope you all read this in LPL's voice.)
Try these to find out how the laser is interacting with these devices: shoot a stethoscope with the laser-see if you can hear something. If so, it’s interacting thermally with the mic. Put a oscilloscope on different non-piezo MEMS devices (non energized) and see if an electrical current is generated.
Non piezo MEMS devices use capacitance as the sense mechanism. There would be no current generated for this type of device.
I'd just guess that light and sound are both waves, therefore can have the same effect of moving a membrane?
@@Julia_Berrrlin As a physics student I can tell you it's really not that easy, we only think of light as waves in some circumstances, other times we think of it as many photons.(double slit experiment) Secondly, in this experiment they are modulating the intensity of the laser, not the frequency (the "waves").
well stream of light has kinetic energy basically, so it could vibrate the mambrane. sun sails concept works that way
Zach Coldwell unless it’s somehow behaving as a solar cell
whenever he said hey google my google home started talking like crazy
nice spyware
I’m not even worried about it.
My Alexa was convinced by it too
You should key commands to your own voice at the very least. Google Home can do that.
Alexa started up saying she didnt understand here.
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.
wow this is like telephone phreaking, just in the 21st century
And inherently bad.
Could you record audio when it is being hit by the laser? Wanna find out how it sounds
you can record audio inside a room from a long distance by laser and a small telescope
@@LateNightHacks and a fat IT guy
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).
The membrane is being excited with the same vibration as a voice, but with light, so, yes.
@@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
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.
Wow...
Mega off
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
That was amazing to watch, my home is full of these gadgets and it's never once occurred to me there could be an issue like this with them.
Let's hope your video gives these companies the kick up the backside they need to help improve the security of the devices.
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.
LockPickingLawyer amirite?
@@WolfgirlSylphie Because if they have the right tech tool, it could actually be much easier than trying to pick a normal lock.
YES, check the lockpickinglawyer's channel
@@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.
"What do you want to be reminded about?" Is all you got from my British Siri.
Edit: I take that back. My Siri is trying to open my garage now.
That Tommy TuTone reference at 14:28 was appreciated.
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... 🤣🤣
Suggested title: "How to heat a house to 70 degrees using laser"
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
The comedy here is GOLD!
Hey Google: "I'm sorry, I don't understand"
Destin: *chuckles* "You will"
