00:00:00.120 --> 00:00:05.799
go ahead USB killer 2.0 yet another USB

00:00:04.120 --> 00:00:11.759
device designed to strike fear in the minds of defenseless non- Tey masses but

00:00:09.360 --> 00:00:16.920
unlike the creatively named rubber ducky or the hacksaw and switchblade USB

00:00:14.480 --> 00:00:24.519
methods thoroughly documented as part of an hourlong 240p epic by hack five back

00:00:20.560 --> 00:00:26.920
in 2006 the USB killer is literal it's a

00:00:24.519 --> 00:00:31.759
USB device that will kill what you plug into it now the original USB killer

00:00:29.279 --> 00:00:36.480
applied a negative charge of 120 volts to the 5vt V USB pin on the port

00:00:34.640 --> 00:00:40.640
effectively destroying the USB controller and its power regulation

00:00:38.120 --> 00:00:45.640
circuitry USB Killer 2 kicks it up a notch bumping up the negative voltage to

00:00:42.640 --> 00:00:48.559
around 200 volts and it hits it directly

00:00:45.640 --> 00:00:54.239
in the data pins chances are any device that you plug it into will no longer be

00:00:50.640 --> 00:00:56.680
functioning properly some may survive

00:00:54.239 --> 00:01:00.600
but the majority won't and terrifyingly enough this isn't just limited to

00:00:58.399 --> 00:01:06.960
laptops and desktop computers it even works on phones TVs and cars if

00:01:04.760 --> 00:01:12.320
you can plug a USB device into it it may be vulnerable to this attack so this is

00:01:09.479 --> 00:01:16.799
the part where I demo it right truthfully I had my reservations

00:01:14.759 --> 00:01:22.320
about actually killing a bunch of Hardware I mean it's been done many

00:01:19.080 --> 00:01:24.600
times before but this is lonus Tech tips

00:01:22.320 --> 00:01:30.000
lonus is the man that bought a $17,000 UPS lonus is the man that decided that

00:01:27.640 --> 00:01:32.720
he needed a 180 terab server just just so that we'd never have to delete a

00:01:31.720 --> 00:01:38.680
single file all in the name of excess so maybe

00:01:36.159 --> 00:01:44.240
it would be appropriate to kill his recently finished desk PC project that

00:01:41.240 --> 00:01:48.040
you guys waited so long to see completed

00:01:44.240 --> 00:01:48.040
so follow me and let's do just

00:01:54.880 --> 00:02:01.000
that oh

00:01:57.960 --> 00:02:05.880
my I didn't actually think was going to

00:02:01.000 --> 00:02:05.880
work okay I'm going to get

00:02:14.480 --> 00:02:20.480
fired mop is currently featuring the Emu

00:02:18.000 --> 00:02:26.040
Purple Heart Clos back headphones check this and other drops out in the link

00:02:22.480 --> 00:02:28.000
below okay so as you probably guessed

00:02:26.040 --> 00:02:32.519
just like all the other YouTube pranks that was fake I didn't get fired the

00:02:30.560 --> 00:02:37.120
computer is fine the flash drive I plugged it into is completely harmless

00:02:35.360 --> 00:02:42.360
uh I just flipped the switch on the power bar with my foot as I put it in

00:02:39.840 --> 00:02:46.879
but the attack is real and the drive I have here now actually in there is the

00:02:44.480 --> 00:02:52.120
real thing USB killer official YouTube channel has plenty of videos showing it

00:02:49.480 --> 00:02:56.480
killing things like Xboxes and even a car and if you won't take their word for

00:02:54.319 --> 00:03:02.480
it our buddy Austin Evans Zapped two different laptops a TV and even a phone

00:03:00.680 --> 00:03:06.959
but how does it work well it actually uses your own device against you when

00:03:04.360 --> 00:03:11.319
you plug your USB killer into a device it Cycles through rapidly charging its

00:03:08.799 --> 00:03:15.280
own capacitors off of the device and then discharging them at the previously

00:03:13.159 --> 00:03:20.519
mentioned negative more specifically about 220 volts a heck of a lot more

00:03:18.480 --> 00:03:25.560
than both the 5 volts USB is designed for and the 15 volts that would already

00:03:23.120 --> 00:03:29.959
have been enough to kill most devices this cycle is repeated many times per

00:03:27.879 --> 00:03:34.159
second until the USB killer is is removed and you can reuse it as many

00:03:32.159 --> 00:03:38.959
times as you want that is until a teacher confiscates it and calls your

00:03:36.000 --> 00:03:43.319
parents do you need to buy one then well people have actually been making their

00:03:40.400 --> 00:03:47.599
own by modifying random USB devices that actually work for it or even taking the

00:03:45.360 --> 00:03:53.040
flash circuitry out of a disposable camera and reworking it to load up the

00:03:49.879 --> 00:03:55.439
capacitor and discharge over USB it's

00:03:53.040 --> 00:04:00.319
not even that complicated you Salvage the transistor Transformer resistor

00:03:57.480 --> 00:04:04.400
diode and capacitor from the camera add a power source if the cameras isn't

00:04:02.159 --> 00:04:09.439
suitable throw a button in for ease of use and then send it all over USB and

00:04:06.799 --> 00:04:13.640
you're done and so is the device and does this crude method work well yeah

00:04:11.840 --> 00:04:19.479
and you don't even need the host device to charge it to test it we grabbed an

00:04:16.000 --> 00:04:23.000
old Acer Aspire One from 2008 that Linus

00:04:19.479 --> 00:04:24.680
had in the E-Waste pile for recycling

00:04:23.000 --> 00:04:29.160
now everything in the computer isn't magically dead I wouldn't trust the

00:04:27.000 --> 00:04:33.840
motherboard or the CPU anymore but the rest should honestly pretty much be fine

00:04:32.080 --> 00:04:38.360
when throwing that much voltage around I'm not going to guarantee anything but

00:04:36.199 --> 00:04:43.080
this isn't a Data Destruction method and the hard drive in here almost certainly

00:04:40.600 --> 00:04:47.080
still works okay so enough about how easy it is for people to Brick your

00:04:44.560 --> 00:04:52.400
stuff how do you protect yourself well the US government suggests not plugging

00:04:49.360 --> 00:04:55.280
things into your computer thanks guys

00:04:52.400 --> 00:05:00.520
outside of that you probably can't physically capping USB ports adding

00:04:57.520 --> 00:05:03.320
so-called USB condoms or installing the

00:05:00.520 --> 00:05:07.840
USB killer test Shield have been cited as ways to defend against this but as

00:05:05.880 --> 00:05:13.800
long as the attacker has enough Ingenuity to unplug whatever you plugged

00:05:11.320 --> 00:05:17.039
in they will be able to quickly bypass your

00:05:14.800 --> 00:05:21.199
protection unfortunately outside of filling all your USB ports with cement

00:05:19.560 --> 00:05:25.080
if anyone has direct access to your computer that is vulnerable to this type

00:05:23.039 --> 00:05:30.479
of attack and they're enough of a dick to actually do it you're

00:05:27.319 --> 00:05:31.880
screwed USB type-c will sort of have a

00:05:30.479 --> 00:05:35.919
solution to this which is a new cryptographic authentication that can

00:05:34.000 --> 00:05:40.560
stop unauthorized and uncertified devices from connecting but as with

00:05:38.600 --> 00:05:45.520
pretty much all things done this way there will almost assuredly be a way to

00:05:43.160 --> 00:05:50.440
bypass it the best way to protect against this attack is to have the

00:05:47.479 --> 00:05:55.360
manufacturer of your device install an opto coupler these are also known as

00:05:52.560 --> 00:05:58.960
photocouplers or Optical isolators they're components that transfer

00:05:56.680 --> 00:06:03.520
electrical signals between two isolated circuits by using light effectively

00:06:01.639 --> 00:06:09.639
preventing high voltages from reaching the entire system even if the port loses

00:06:06.599 --> 00:06:12.599
its ability to transmit and receive data

00:06:09.639 --> 00:06:17.120
this is better than nothing but not many companies have even implemented these

00:06:14.919 --> 00:06:22.319
outside of Apple so be sure to hit up your favorite device manufacturer and

00:06:18.759 --> 00:06:24.479
tell them to get a kraken in conclusion

00:06:22.319 --> 00:06:29.599
just as we've always said don't plug random USB devices into things if you

00:06:26.560 --> 00:06:31.759
don't trust it just throw it away and no

00:06:29.599 --> 00:06:35.440
this isn't a meme or a hoax you shouldn't try this on your friend's

00:06:32.840 --> 00:06:40.000
computer because it's illegal and honestly it's just not even funny you're
