Just plug it into ever pc you touch and tell your professor that you have your midterm or entire semesters notes on there and you dont know why computers turn off when you put it in
I don't get why this is such a big deal. If I gave someone full access to my laptop he could also just throw it out of a window. Can't I just assume people aren't assholes?
Can you change the profile pic of your youtube account? Something more generic and connected to brand in general, not the person. no disrespect to linus, hes awesome but you should change it
LinusTechTips Uau you actually answered! Thank you, love your videos. I only play on consoles but I always try to learn something about pcs in your videos!
Some dicks plant USB killers in public "USB drops" so random strangers can fry their laptops/phones. The only thing worse than a dick is a dickless dick.
A proper security policy with common defense in depth layers can greatly increase an individual's ability to protect their data from the attacker even if they have physical access. You can take it pretty far even to the point of creating custom triggers that will set off an event in case someone is able to break into the computer case to try and connect USB headers or the like.
To put pressure on hardware manufacturers so that they fix that shit. The more common devices like this are, the sooner manufacturers will have to act, which will benefit all of us.
Dood ! Thats a stupid explanation. Imagine that: Person A installs a bomb in Person Bs Car, which is activated by their car keys. If Person B presses on their car key button and his car explodes, is it his fault that his car got destroyed? Obviously not. By your logic, most hackers wouldnt do anything illegal.
This isn't a software problem like viruses, this is on a hardware level, so an antivirus probably won't do anything, except for the off-chance that the antivirus disallows certain USB devices based on certain definitions of what a harmful USB device is.
US gov probably arrived at those decisive findings after a $200M study, 24-month engineering analysis, panel discussions and committee interviews of leading security experts, etc. A comprehensive 2500-page report can probably be downloaded. Assuming it's not classified.
I don't know what do you see more often an iPhone 6 or an iPhone 7? And btw the iPhone 7 sales were healthy at the beginning but decreased relatively fast.

Because, as with most things, it is up to people how they use it. A man could use a truck to run down a bunch of holiday shoppers (too soon?), so should we never sell motor vehicles? A knife can be used to stab/cut someone, should we never sell knives? All it takes is one person to have a legitimate use case for this that ISN'T illegal (say, making a video about it?) and at that point we should trust people to do the right thing, even if sometimes they don't. Creating a nanny state where we wrap everything in bubble wrap and constantly surveille people to keep them from hurting themselves and each other is not the proper solution.
its main purpose is for companies to check their port's defense against overvoltage/whatever it called (Some devices' ports are immune to this USB killer, like iPhone's lightning port.)
You could just use the BIOS or other special software to disable all vulnerable ports, like the person that made that Samsung Netbook filled with malware “art” that went for a few million did.
Incase you have important documents on your computer (or something of importance) you could quickly plug it into your own computer if you were ever atttacked or someone tried to steal your computer and get things from it. I assume this is one of many reasons.
+THEmickTHEgun Even if the HDD's internals are dead the data would still be there and readable by specialists as they are based on magnetism, not electricity. If you want to protect data you can just encrypt them and don't need to wreck any hardware.
Try me, I use a ASUS Eee PC successor as my main laptop. It’s a ASUS VivoBook E12 E203NAS-YS03 (Intel Celeron N3350, 4GB RAM, 64GB eMMC (dual booting heavily modded and customized Win10Pro and heavily modded and customized Ubuntu 20.04))
Thomas Champliaud a USB dead drop is a publicly hidden USB that you could access anytime, you can put any file in it and share it to other people who will use the dead drop in the future. If you change the USB to a killer one you could kill the laptop of the person using it.
O SHIT I LEFT MY SECRET SPY CO-CONSPIRITOR THE WRONG USB DEAD DROP! AND HES TAKING TO TO PLUG INTO HQ'S MAINFRAME!!!! AND WE'RE ALL HARDWIRED INTO THE SERVER!!!! MY BOSS IS GOING TO KILL ME!
HUGSaLOT Valkyrie The CE mark is something a company puts on their products to show that their item follows CE regulations It's not a test facility, it's a promise the company makes
Actually, the threat is completely different: you leave this lying around, people pick it up and plug it in. Of course you can destroy a PC that you have physical access to, but it's hard to make someone hit their PC with a sledgehammer...
Nawaz Waseem yes but the real threat is teenage pricks who attack your phone or laptop on the go over a bet or something. Or a really pissed off family member. I had a friend who made his brother mad so his brother USB killed every electronic in his room.
@@Entropy67 Plane USB ports are isolated and the only result would be a blown fuse on whatever bank/usb controller your usb outlet is associated with, aka you and your neighbor get no power. The rest of passengers won't even be affected.
@@taylorg7352 Doesn't exist. If you are saying avionics, that has a breaker and would kill the port upon detecting such high power. That and avionics is located in the cockpit, gl getting in there with a USB killer. end point: planes are built to be redundant. Fun fact twin turbine airliners technically only need one engine to fly, they put 2 cause redundant.
Budred123 that would be expensive. that would be 6-16 fuses per motherboard + they would have to drop a lot rnd money to make tbem work well in such a confined space.
No worries, I spent 20 years in the computer building/repairing business. I got board and got into automotive repair. Been doing that for the past 4 years.
Ivan Milan well buy was kinda a lie, I built 4 bought one to get a idea how there bult! there pretty easy to build well easier to build then a Raspberry gamboy!
You could try creating a energy capacitor limit to the hardware within the USB to limit the amount of voltage that can be put into a USB device and how much the device can discharge
You guys should talk to some engineer before publicly testifying on engineering stuff. Optocouplers won't work on this case. The power lines could still be attacked, and no one will place an Optocoupler in front of a USB 3.1 data line for signal integrity and cost reasons.
you could protect the data lines with small optos. the power lines of the usb could be protected by just having a semiconductor fuse paired with a snubber + some kind of heavy duty zenner. I have thermistors that will cut a 2000v transient to about 2 volts and if you cascade 2 of them well you can be protected against this kind of attack (you can buy fully made circuits, sinetamer has great ones. ) of course if you have a source with a low output impedance there is no way of protecting a board. It will be like using a welding electrode in de usb port lol!
It's not that simple on this particular case. We are talking about very High Frequency lines, you would have to use an optocoupler that won't disturb a 5GBit line and respond on the same speed, that's not going to be practical on a cost perspective, those are not the cheap optocouplers we usually find. Also zeners, TVS and etc. are made for fast transients this won't be an occasional disturbance on the line, this will be a step-up converter, this could fry all this protections by not leaving them time to dissipate the energy as heat, not even mentioning the PCB clearances you will have to leave for the High Voltage isolations to avoid creepage so the arcs wont jump to other exposed pads nearby. So practically this will increase considerably the cost and size of the product so no manufacture will care to implement it. Theoretically, yes, you can protect any line you want from any kind of voltage, but this case it's just beyond practical.
Funny thing: If you fry an airplane's electic system it can still land with ease. You need to also fry the captain and wingmen to seriously damage the plane. ;)
TheArzonite I wouldn't do anything, it would absorb it all depending on how big it is. like the worst it could do would be warm it up a little, but enough could probably fuck a server base up.
Even if you could somehow find a USB port that connected to every single server they had I doubt it would even be enough to destroy them considering how insanely beefy they are
Caverri A tazer operates at 50,000 volts while flying through the air, and at 1,200 volts once the barbed contacts enter flesh. The most powerful ones operate at 50,000 volts, 26 watts, according to Taser USA. Tazers will absolutely kill a computer dead.
I'm not familiar with arc lighters. From my knowledge of electrics, I would guess that they use higher amperage rather than voltage. But again, I'm unfamiliar. Either way though, they can still probably murder electronics pretty good.
Caverri arc lighters do shock you with 8000v. Most people think it's just some high frequency noise that doesn't hurt you but iv'e tried putting a metal piece and make contact with the beam and it does hurt. but the beam is so small that only tiny stuff can touch it but i wouldn't try
Omna Aggvin Please explain why average is better than median for this purpose. If I'm interested in finding the majority lower half of the viewing age, which do i pick?
The Arctic Warfare L96 high-powered sniper rifle that can be silenced and scoped on a budget! With this powerful product you can precisely and safely destroy any piece of tech in an up to 2000 meter range! All of that for the low low price of £5999.99 (ammo and accessories are not included)
Alex theTroller even a monkey would have understood that i was talking about luke getting fired. it has become a joke, in one wan show luke got fired a couple of times if im not terribly wrong. i applaud them that they didn't fry up good hardware just for the sake of bullshit views just like the majority of "tech" channels(everythingapplepro, unboxing theraphy, etc..)
Encouraging hardware manufacturers to take action for overvoltage protection over USB interfaces. At least that's what I know about its usage. Also what HistoricaHungarica said, knocking common sense into peoples heads is another use of it.
My asshole childhood friend would have almost certainly done this to my PC while holding me back with his other hand and then I would have collapsed crying explaining to him that computer cost me and my family $1000 and a year of saving to buy and then he would have laughed frantically, and then my mom would have come home and cried too. I don't know how you can be a kid today... Too many ways for technology to ruin your life.
Well, if you have a Laptop you can certainly modify it to a good extent. I did that with mine, soldering away the connectors that are connected to the Motherboard directly, making the USB ports unusable. I have a Trackpad and Keyboard built into the Laptop, and i am not using the Laptop for any kind of Gaming while i am walking around, so i am good. Also, you can actually even fix that with adding internal USB connectors, either (on a Desktop) by adding a PCIe extension with inside connectors, or (on a Laptop) re-soldering the original connectors to wires, then soldering the wires to lose USB connectors you can attach things to on the INSIDE of the Laptop (opening the bottom panel or the likes where the HDD is, there you can have the USB hanging if there is enough free space for it). Everything can be fixed if you want to fix it.
Unplug the USB header from the motherboard, block every USB port by using glue and install some of these USB Isolators to the motherboard using an adapter and attach them to the back of your PC-case for accessibility.
And this is why I always dissemble USB devices unknown to myself. The easiest way to protect yourself against the USB killer is to get an *USB-ISOLATOR* ! Manufactures should install something like an ADUM4160 for protection. The alternative is to solder Varistors/VDRs (Voltage Dependent Resistors) in parallel and PTC-Thermistors in row to the data- and voltage-pins of the USB-port.
So knifes should be illegal too. This product will improve hardware physical security. Also if someone wants to destroy someones stuff then it isn't hard to DIY that stuff.
Film it so you could at least pay them back with some of the youtube money. O don't forget to get a friend to film you when a larger kid who just lost all his work is beating the shit out of you too.
I already design my USB devices with 1500kv isolation and it still takes up board space but not as much as you would think the issue is that even with isolation, you need to also have a spark gap for high voltages.
SaekoDashie hello, i am back...now lets see... I may be a quality human being and you may be following me on youtube without even know it... but since I am sure you don't know the basics of hacking (because I would have been already fucked), I can continue make fun of you without getting punished. If you use "quality" in an ironic mode, please use captions since we are typing to each other, and not speaking face to face. What you wrote there makes you look dumb. That enumeration is completely useless and I doubt you really know what the neo-nazi agenda actually is since I am again, sure, that you just write things you heard about, without getting into details. I don't know how you already think that if I "breed", my child will instantly get every feature I have. Genetics doesn't work by passing 100% of the genes of one parent you know... Don't cry yourself to sleep. It isn't worth it to defend some random guy with some subs with annoying voice on youtube :)
Even with optocouplers, the diode inside could die of high voltage. There is no clear way to protect against a very crude attack like this. Not even the "cryptography" could help. Sure if the USB port won't output current unless some device negotiation happens, but then again the whole point of USB is its simplicity and this would just ruin it. Seriously, you could just as easily use a tazer to destroy a USB port like this.
imawhale Why a hammer? Might as well use a bunch of sulfur acid to destroy it. It's not about computer destruction per se, it's about how much damage you can deal to a computer over a USB port. This could just as easily work on a PS/2 port if you got one.
The optocouplers will keep the damage local to the port, and maybe the PSU. That can only work if they're given separate circuits from the motherboard, of course. Yeah, there's still damage, but it's not as expensive. As you say, though, there are other ways. It really depends how far you want to take this security. A simple cup of water can be a pain in the ass too. I think the cryptography is used to protect against BadUSB rather than this attack (I know he said this attack in the video) because the firmware on the device can be verified using a cryptographic signature before running. I don't know all the details, but it should stop a USB drive acting like a keyboard.
Lewis Hazell Well this is a purely electrical attack. It does not care whether you have 10avs or encryption or cryptographic signatures. It's going to fry the mobo & port anyway.
StackableGold no, I'm studying automotive mechanics, the only think you would destroy would be the ECU which the car won't start without but a new computer depending on the car might only cost $300
I agree, but there is still no point in making it illegal. You don't even need this device to kill hardware. I'm pretty sure 80% of people have replaced a wire with a plug on it. Instead of changing the plug, connect the wires to the pins of the usb. Plug the wire in the usb and then in the wall and say goodbye to your computer. If someone really wants to fry your computer, illegal or not, they will find a way.
Yeah thats how linus can live forever he buys organs,blood and nurons and inplant them into the body totally normal its not like linus is the CIA's most wanted person
how to get free hardware: step 1- take usb killer to school and plug it in to as much computers as you can step 2- stand by garbage bin outside, then when computers arrive thats free hardware
