@@freedustin With a little social engineering, no problem. Send a "free" flash drive in the mail as a fake promotional. Give it to them in a swag bag. Become their friend and tell them the photos from the other night are on there. Convince them to print or scan a specific type of item at their local print shop that requires a flash drive and make sure, when they go looking for one (because who has those laying around anymore besides tech people thanks to the cloud), the malicious one is the first one they find. There are a million ways you could social engineer a specific target into plugging a USB into one of their computers. That's just what I came up with in one minute...get creative.
Before USB there were versions of this for PS/2. They were largely used for some of the same legitimate tasks, usually some form of automation, or, in some cases they could act as a converter between RS-232 and PS/2 for some serial devices. The tricky part of these USB HID "attacks" is that unlike the old route of a malicious autorun, you can't avoid it by holding shift, and of course once it's plugged in, it gets activated and can start "typing". Some AV software has started adding "keyboard authorization" features to try to combat these types of devices. One interesting approach of dealing with a suspicious "drive" is to plug it in while in a VM (with shortcuts to 'escape' the VM disabled) . Even though it will connect to the host machine, if it is device like this, then keystrokes it tries to send will go to the VM. Heck a MS-DOS VM running a tiny DOS program that just logs key scancodes to a text file could even provide insight on what exactly it is trying to do.
Glad that your highlighting security tools, tricks, and remediation. Keep doing videos like this. As a security professional I think tech UA-camrs can play an important role in educating users
10:35 Thanks Linus. Now I know what a rubber ducky looks like. I can safely plug in that USB I found this morning on the sidewalk - it doesn't have that folding silver shield on it, so can't be a rubber ducky.
That's what I thought it was first too. I think Linus didn't think that part of the otherwise good presentation through. I also would have liked to see some practical advice on how to avoid being hurt by this in real life (other than the obvious "don't attach a USB drive that you find on a street to your computer). Anyway, I think this was a very interesting and generally very well made presentation.
The main infosec advice I give to people is simple "Unless you know what it is, don't put it in". Works decently for other bad decisions you make sometimes too.
Ah yes, the old USB port as an attack vector. Funny you should mention DSM, because one of their SysOps gave a talk at a local small time Defcon type of convention and he mentioned the use of hot melt glue to stop USB port based attacks. Still I always figured that given what we did as kids in high school during the 90s these kinds of attacks would be obvious by now. All of the computers in HS ran NT4, so their drives were NTFS. Except for the computers in the computer lab, because due to curriculum requirements those were W95 machines. Now IT had considered that diskettes would be an attack vector, so they passworded the BIOS and made the A and B drives non-bootable. Except they messed up. All the BIOSes had the same password. Windows 95 is basically a glorified DOS shell, so any user would have low-level access to the hardware. So use W95 to make a dump of the BIOS, take it home, grep the password from the dump. Prep a muLinux diskette with the NTFS read kernel driver, use BIOS password on NT4 box to enable booting from diskette. Boot up muLinux, grab the SAM files, take em home and run L0pht at your leisure. It left no trace on the school computers and meanwhile we had Domain Admin level access.
Those are old news, but its good that someone from the mainstream is actually covering this attack venue, and yet another lesson on why not to plug random USB accessories willy nilly
I've been watching Hak5 since 2006, LTT since about 2015..... I was SUPER excited to see this video pop up. I really really hope there's more! Commenting for the algorithm to show this is a great video!
Can you build a 5 minute version of this? I would love to share this with my non-technical staff, just so they can know the danger. Heck, that would be a fantastic new channel--security issues for non security people.
@@madness1931 I’m thinking more like Security in Brief. Most security information geared to the regular user is full of stock photography and over explained by experts. The section on USB sticks and how they pose a security threat was the simplest I’ve seen. That could be done for phishing, passwords, etc. Maybe sans the condom, as that wouldn’t fly in my environment. But the security content was perfect for my users.
I always wondered if they were going to ever release a newer version of the Duckie, I've had mine for years and it is a super useful tool, especially if you work in I.T. and have to do mundane task, I use mine to install software we use at work after a reimage
I moved away from theirs to Michal monday on github he has a supreme ducky albeit a bit out of date now but found it loads better than hak5s not looked into their 2nd version.
Fun facts: The clip in the beginning ( 0:09 - 0:18 ) was a TV-Ad that was actually shown in the early 2000s in germany. The conclusion „So wach warst du noch nie“ at the end means something like „You have never been more awake than now“ and advertised a coffee drink with high caffeine content. There were many complaints due to horrified children and dropouts of pacemakers because of this ads.
I remember in the late 80s/early 90s we had to write software on public computers and the only way to save our code was with floppies. We were constantly running into issues where our own floppies that we bought and formatted on our machines, got infected.
Yep, I remember that. First the 5.25 inches, then the 3.5 ones. And those utilities allowing to use extra capacity (2mb total, I think) beyond 1.45 mb. Or the ones which could be used to fake a ram disk to allow certain installations. I remember always knowing even which floppy disks I had as infected. You could recover from that, but was not easy.
Using this as a means to automate bench setup is pretty ingenious. Been subbed to the Hack5 channel for a while and totally love what they did there! It's a research tool in one hand, or a weapon in another. Great video!
I've been using a ducky for 5 years to automate changing settings in windows and install software for machines we sell to customers to ensure that they are ready to use out of the box.
I worked for DSM at a local industrial site before our buy out and when I tell you that our classes RAMPED up and they locked our machines. We weren’t allowed to use anything in the machines unless it was provided by our it team.
This would be pretty fun to write a harmless script that forces a friend to listen to the entire duration of never gonna give you up before they’re allowed to use their computer again
Great video! Though you should have shown the Ducky as several different looking USB sticks. A novice might only watch out for a stick that looks like the one you are showing. And it seems to me like you are trying to communicate to novices too. Otherwise I have nothing to complain about and found the video very well written and informative.
I almost bought one of these a long time ago. Then I realized you can do the exact same thing with a $5 arduino board. The script language is a little more complex but gives you wayyyyy more features, plus you can add other devices to the arduino like wifi, bluetooth, even capacitors to make your own badUSB. You can go even further and buy "fake" arduinos for even cheaper ($2 in bulk) that do the same thing, 3D print a bunch of harmless looking USB shells and then drop them around the city. Not that i've ever done that.....
Right all of this information is clear, the rubber ducky was meant for ease-of-use. The hack.5 gang has always been script kiddy friendly. The more we arm the masses, the better awareness we all share.
I mean I really hope you never did that. Because that would make you look like a real creepy looser if you did. But you didn’t so that’s not a concern right?
@@goodnight4u I definitely didn't but if I had it would of just pinged a server I had setup as a part of a paper I may have done on cyber security for a college class.

Most people have absolutely no idea how scary these things are lol. I ordered one a few years ago to play around with. I don't use it much but I still carry it around with me in my laptop bag. The first day I had it I managed to build a payload that when plugged in within a few seconds would grab every single one of my saved Google chrome passwords and email it to myself. My jaw hit the floor when that email came in with my entire password list in it lol. From that point forward I pretty much NEVER walk away from my laptop at work without locking it. It's insane how much damage someone can do with one of these and a little know-how and 5 seconds of access to a USB slot on your device.
@@MRJMXHD Slow? Really? I loved it. It really takes off season 3 and 4. Stick with it because it all comes together. This show has some of the best directed episodes I've seen on television. The first season is a bit smaller in scope, but becomes a much bigger story as it goes along.
I made one of these with a cheap raspberry pi Pico and it works amazingly, and it is extremely easy to use, they are really help full when trying to code or set up something on multiple computers because it automates it.
This could be very useful for destroying scam call centers, because you know how much of a plague those scammers are! Create a script that completely wipes the servers and BOOM! No more call centers!
The device is double edge swords, in the right hand it could used as tool to help productivity, but in wrong hand it could become potentially tools to harm the network or computer at same time. Trully depending who is use that, the rubber duck could be become bloody rubber duck or just harmless rubber duck
Linus said in the video it was to automate software installs as a system admin, insert the key into a Windows machine, and let it do it thing, while you walk away to work on something else without having to babysit a single machine for say 10 different pieces of software to install.
Just realized my passion and finally started pursuing a comp sci degree this semester. And I'm quite proud of myself because I actually understood every single issue you guys listed with the ducky. I love this field haha
I know of one virus that spread through USB, I forget the exact name of it, but I had it both from a school computer and a mobile radio station computer. The way it worked was: if you inserted a USB drive, the computer had a background task running that would hide all your files/folders, and replace them with shortcuts that both opened the file, and opened the virus, spreading it to your machine and anything else you plugged into it. Luckily for me, AVG free was able to pick up the virus file on my drive the first time, so I was just stuck with shortcuts for icons (easily fixed with some cmd trickery). The second time I recognized what happened and removed it myself (lucky me I had autorun disabled and the virus couldn't run itself, for some reason).
If you don't need the built in storage, I'd recommend a Digispark USB. It just uses Arduino code, and there's programs that translate RD scripts to run on them. Plus they're like 20$ for a 5 pack. I've been using them for automated thin client setup.
Interesting use for automating your PC setup. Have you also tried UiPath process automation?! It can perform way more complicated stuff and it seems easier to setup that this rubber ducky stuff. Nice shoutout to the Konami cheat code, I'm a game dev :D
Why would anyone use an external device to run a setup script, especially one that is so limited? If you already have access to the computer, just put the payload on a regular flash drive and run it...
Or Ansible. This is a neat tool but, for businesses, there are much better options for imaging computers and setting up software. Most software can be baked into the ISO image.
The Writer, Tanner McCoolman, was excellent for this video. As someone that was trained in CySec and learned how to use a USB Rubber Ducky, it was very well explained on how this attack vector works!
I would love to see you do some in-depth vids on the rest of the Hak5 line. I've actually taken to using my old Mark V Pineapple as my IOT access system in my DMZ which let's me rain hell down on bot-net sweeps and the occasional budding hacker that war-drives by for crits and giggles lol.
This is actually why a lot of businesses will prevent you from plugging in any keyboard except the "certified" ones. I think Active Directory even has a feature for that
We actually still configure all of our work machines with PS/2 ports and you can only connect a keyboard to that port. It’s an annoyance but they was the strategy they decided to go with.
@@GulfCoastGrit I wonder if there could be wireless PS/2 keyboard transceivers. After all, as far as the computer is concerned wireless USB peripherals are identical to wired ones.
This usb stick saved my ass on my first job of manually setting up computers in every classroom, i could plug 2-3 pc at the same time, log in and perform the routine task before lunch break in a single day

@@matthiasschuster9505 Yeah... But they very easily could make a library for another language that handles all the timings and things. Creating a whole new language seems a bit far.
@Ian Visser that's not quite what I meant. I understand what this device does, but I don't see why a new language was required when a different language with a library would have sufficed. Sure it simplifies the scripting I guess, but it still seems like a lot of trouble rather than making a library.
Hey linus i doubt this will ever been seen but ive got an idea for a video for you, i recently bought a gaming laptop with an i7 and 3060 and it gave me the inspiration for the idea. The challenge is get every big computer youtuber you can think to chip in a single completely random spec component of a custom gaming pc (good or bad) preferably intel and give it away to a random fan ones the build is complete
I always do! To be fair, I have an extra shitty computer that is connected to nothing and am not a afraid of losing anything on it. I'm not about to let some e-waste go to waste.
I had a college teacher do that to USB stick I left in his class. It was basically empty with just a couple photos on it from when I was in the military I kept it around as a backup, and it fell out of my backpack...dude literally just plugged it into his computer to find out what student left it in his class. He found it and gave it back to me and told me "be careful you wouldn't want to lose one of those with important information on it". This professor was the schools lead as far as like...tech classes. He pretty much ran the IT department..this was at a community college.
VM's could totally be an option. I don't know about Windows, but on Linux using qemu you can pass an entire USB controller to a VM, so if you plug the ducky into a specific port it controls the VM
Ah yes, good idea to send everyone on the hunt for ducky disk images, just to make a stupid jumpscare prank, only to find themselves downloading a tainted version with a backdoor or worse. Will be so much fun. Thanks Linus, for spreading the word.
One time back in middle school my cousin found a flash drive on the school bus. This was well before I even knew what "computer security" meant. We plugged it into a PC to see what was on it. Luckily it didn't do anything. It was just FULL of prawn. Lots and lots of really hardcore prawn. We erased the drive and I gave it back to him and we never mentioned it to anyone.

my 2 Favorite Tec channel cross over? hak5 was my fav in the past with Darren Kitchen and Snubs.... Now Linus is reviewing a Rubber Ducky key? amazing!
I hope the dide taking the usb stick to IT security got a bonus. Hardly anyone does that. Even many IT people would just carelessly plug it in. And that's why social engineering is even a thing. If technical security measurements get better and better, the only weakness that's basically impossible to reliably patch is the user. Humans will always make mistakes. That's why it's more important than ever before to make people aware of those threats and educate them. I think that devices like this should be legal. The main reasons are 1. Someone will do it anyway, no matter if it's legal or not 2. If it's done anyway it's better to make it public to show that devices like that exist and what they can do
At my workplace, the desktops had just the two USB ports for the keyboard and mouse enabled for just HID, and all others disabled. IT are the only ones that can get files off a flash drive using an isolated, disconnected machine with various malware scanners.

Or ANY usb device for that matter. Webcam, mouse, printer, once the USB gets plugged in, it's game over.
Theres already something called duckhunt which detects ultra speed typing.
@@suzierottencrotch7893 you just slow the typing speed down to a human level and while slower is still automated

It was an honor alone just to be in a video!

@@PlanetXtreme I appreciate you! I've put a lot of effort into trying to make something legitimate to offer 😀
Don't mind me riding Jakoby's coat tails here 😉 Funny to see my 32 wants the D payload refrenced. People can feel free to check out my repo as well.
Just now do I realize that I actually want one of these, being able to plug in a drive and have it automate a couple commands looks useful as hell
I saw this an my first thought was automating installing emulator games via USB
This better be the start of a Hak5xLTT collaboration! Fly Darren and Shannon up to The Lab and let's get a few videos out of this!!
Yes! I'd love to see that
@@GB570 Hell nah, the way the Rubber Ducky for example works is people simply not being aware of it. Any kind of attention kills it, so a UA-camr with about 15 million subscribers making a video specifically about it is horrible. Not for Hak5, but for the users. The OMG Cable would be another example, also from Hak5.
@@anon_acc You're missing the point of Hak5. They want more people aware of security vulnerabilities so that they know what to look for to protect themselves.
@@anon_acc I don't think that Hak5 would agree. They want people to be aware of the threats posed by their tools.

@@ducksongfansthat moment when being illiterate is the best defense 😂
At a University near where I live they scattered 50 of these around with a simple script to ping a specific IP so that they could record how many People plugged it in. They recorded 80 different IP Adresses.
So in other words, it'd be stupid easily to hack people if you had malicious intent? And people let their curiosity get the best of them rather than their common sense?
@@QuackZack at random yeah, good luck nailing a specific target tho.
@@freedustin With a little social engineering, no problem. Send a "free" flash drive in the mail as a fake promotional. Give it to them in a swag bag. Become their friend and tell them the photos from the other night are on there. Convince them to print or scan a specific type of item at their local print shop that requires a flash drive and make sure, when they go looking for one (because who has those laying around anymore besides tech people thanks to the cloud), the malicious one is the first one they find. There are a million ways you could social engineer a specific target into plugging a USB into one of their computers. That's just what I came up with in one minute...get creative.
Before USB there were versions of this for PS/2. They were largely used for some of the same legitimate tasks, usually some form of automation, or, in some cases they could act as a converter between RS-232 and PS/2 for some serial devices. The tricky part of these USB HID "attacks" is that unlike the old route of a malicious autorun, you can't avoid it by holding shift, and of course once it's plugged in, it gets activated and can start "typing". Some AV software has started adding "keyboard authorization" features to try to combat these types of devices. One interesting approach of dealing with a suspicious "drive" is to plug it in while in a VM (with shortcuts to 'escape' the VM disabled) . Even though it will connect to the host machine, if it is device like this, then keystrokes it tries to send will go to the VM. Heck a MS-DOS VM running a tiny DOS program that just logs key scancodes to a text file could even provide insight on what exactly it is trying to do.
Can it access the host machine even if the operating system was different from the virtual machine
@@petelee2477 it's an automatically typing keyboard - it requires exactly right context (usually empty desktop) to start working properly
@@petelee2477 Don't rule it out. Malware can escape virtual machines. With this tool in particular, unlikely.
Glad that your highlighting security tools, tricks, and remediation. Keep doing videos like this. As a security professional I think tech UA-camrs can play an important role in educating users
I was wondering if LTT would do more security-related videos like the Rubber Ducky. I was pretty excited for this.
You know wireless BadUSBs exist, they're open source too : ) search for them on UA-cam
Oh Seytonic, glad to see you here
“There safe trust me”
Yo it’s seytonic love the videos dude
10:35 Thanks Linus. Now I know what a rubber ducky looks like. I can safely plug in that USB I found this morning on the sidewalk - it doesn't have that folding silver shield on it, so can't be a rubber ducky.
That's what I thought it was first too. I think Linus didn't think that part of the otherwise good presentation through. I also would have liked to see some practical advice on how to avoid being hurt by this in real life (other than the obvious "don't attach a USB drive that you find on a street to your computer). Anyway, I think this was a very interesting and generally very well made presentation.
The main infosec advice I give to people is simple "Unless you know what it is, don't put it in". Works decently for other bad decisions you make sometimes too.
Ah yes, the old USB port as an attack vector. Funny you should mention DSM, because one of their SysOps gave a talk at a local small time Defcon type of convention and he mentioned the use of hot melt glue to stop USB port based attacks.
Still I always figured that given what we did as kids in high school during the 90s these kinds of attacks would be obvious by now.
All of the computers in HS ran NT4, so their drives were NTFS. Except for the computers in the computer lab, because due to curriculum requirements those were W95 machines. Now IT had considered that diskettes would be an attack vector, so they passworded the BIOS and made the A and B drives non-bootable.
Except they messed up. All the BIOSes had the same password. Windows 95 is basically a glorified DOS shell, so any user would have low-level access to the hardware. So use W95 to make a dump of the BIOS, take it home, grep the password from the dump.
Prep a muLinux diskette with the NTFS read kernel driver, use BIOS password on NT4 box to enable booting from diskette. Boot up muLinux, grab the SAM files, take em home and run L0pht at your leisure.
It left no trace on the school computers and meanwhile we had Domain Admin level access.
man you old
Those are old news, but its good that someone from the mainstream is actually covering this attack venue, and yet another lesson on why not to plug random USB accessories willy nilly
I guess so, even their wifi and ethernet taps are old stuff too
@@username8644 i get the sentiment, but bro i just ahd a stroke
That recreation of the Mr.Robot's scene with the usb thumb drive taken and plugged in by the cop was funny AF with Colton being the victim 😂
I've been watching Hak5 since 2006, LTT since about 2015..... I was SUPER excited to see this video pop up. I really really hope there's more!
Commenting for the algorithm to show this is a great video!
I bought one of these to automate iPad and Mac deployments when we aren’t using DEP. Saves SO MUCH TIME, it just needs to be updated occasionally
10:40 Remember kids safety first
😂
Can you build a 5 minute version of this? I would love to share this with my non-technical staff, just so they can know the danger. Heck, that would be a fantastic new channel--security issues for non security people.
That would be amazing. I want to send this to my family too.
Im into that
Isn't that just Techquickie? Dumbed down tech info, for the average Joe.
@@madness1931 I’m thinking more like Security in Brief. Most security information geared to the regular user is full of stock photography and over explained by experts. The section on USB sticks and how they pose a security threat was the simplest I’ve seen. That could be done for phishing, passwords, etc. Maybe sans the condom, as that wouldn’t fly in my environment. But the security content was perfect for my users.
@@slhuck and hosted by jake or anthony.
I always wondered if they were going to ever release a newer version of the Duckie, I've had mine for years and it is a super useful tool, especially if you work in I.T. and have to do mundane task, I use mine to install software we use at work after a reimage
I moved away from theirs to Michal monday on github he has a supreme ducky albeit a bit out of date now but found it loads better than hak5s not looked into their 2nd version.
This is probably the best advertisement they could have asked for. I'd bet tens of thousands of people bought it after watching your great promotion.
Fun facts:
The clip in the beginning ( 0:09 - 0:18 ) was a TV-Ad that was actually shown in the early 2000s in germany. The conclusion „So wach warst du noch nie“ at the end means something like „You have never been more awake than now“ and advertised a coffee drink with high caffeine content.
There were many complaints due to horrified children and dropouts of pacemakers because of this ads.
I remember in the late 80s/early 90s we had to write software on public computers and the only way to save our code was with floppies. We were constantly running into issues where our own floppies that we bought and formatted on our machines, got infected.
Yep, I remember that. First the 5.25 inches, then the 3.5 ones. And those utilities allowing to use extra capacity (2mb total, I think) beyond 1.45 mb. Or the ones which could be used to fake a ram disk to allow certain installations. I remember always knowing even which floppy disks I had as infected. You could recover from that, but was not easy.
I'm surprised he hasn't reviewed one of these sooner. I've used these for years, amazing tools, but also pretty deadly if you wanted to use it as such
You really emphasized "Being safe" at the end there🤣
😂
I was NOT ready for that
0:29 i love how that website is considered cyber crime
6:00 This did not age well post session cookie hack.
Damn, there’s even a USB-C version. Nobody is safe.
Coltons Reaction was F***ing priceless even if it was staged XD 🤣
Love seeing this, I would love more security integration from LTT in videos ❤
5:56 the irony here is palpable - this scene didn't age very well for LMG.
Using this as a means to automate bench setup is pretty ingenious.
Been subbed to the Hack5 channel for a while and totally love what they did there! It's a research tool in one hand, or a weapon in another. Great video!
So cool to see Linus tackling some cybersecurity now. Everyone could use some extra awareness.
It would be interesting if LTT did an interview with Darren Kitchen or Shannon Morse on their products.
I've been using a ducky for 5 years to automate changing settings in windows and install software for machines we sell to customers to ensure that they are ready to use out of the box.
I worked for DSM at a local industrial site before our buy out and when I tell you that our classes RAMPED up and they locked our machines. We weren’t allowed to use anything in the machines unless it was provided by our it team.
These are VERY useful tools, different versions too!
Colton running malicious software did not age well in hindsight did it? :P
You should check out Hak5's "OMG Cable" - it's a spoof Lightning cable that actually has malicious capabilities too.
This would be pretty fun to write a harmless script that forces a friend to listen to the entire duration of never gonna give you up before they’re allowed to use their computer again
Great video! Though you should have shown the Ducky as several different looking USB sticks. A novice might only watch out for a stick that looks like the one you are showing. And it seems to me like you are trying to communicate to novices too. Otherwise I have nothing to complain about and found the video very well written and informative.
I almost bought one of these a long time ago.
Then I realized you can do the exact same thing with a $5 arduino board. The script language is a little more complex but gives you wayyyyy more features, plus you can add other devices to the arduino like wifi, bluetooth, even capacitors to make your own badUSB.
You can go even further and buy "fake" arduinos for even cheaper ($2 in bulk) that do the same thing, 3D print a bunch of harmless looking USB shells and then drop them around the city.
Not that i've ever done that.....
Right all of this information is clear, the rubber ducky was meant for ease-of-use. The hack.5 gang has always been script kiddy friendly. The more we arm the masses, the better awareness we all share.
I mean I really hope you never did that. Because that would make you look like a real creepy looser if you did. But you didn’t so that’s not a concern right?
@@goodnight4u I definitely didn't but if I had it would of just pinged a server I had setup as a part of a paper I may have done on cyber security for a college class.
Very excited and happy to see Linus mentioning Darren Kitchen, two of my first and most favourite youtubers.
There are a ton of other hardware based hacking devices from Hak5, we would really like to see those to be featured in LTT as well.
Most people have absolutely no idea how scary these things are lol. I ordered one a few years ago to play around with. I don't use it much but I still carry it around with me in my laptop bag. The first day I had it I managed to build a payload that when plugged in within a few seconds would grab every single one of my saved Google chrome passwords and email it to myself. My jaw hit the floor when that email came in with my entire password list in it lol. From that point forward I pretty much NEVER walk away from my laptop at work without locking it. It's insane how much damage someone can do with one of these and a little know-how and 5 seconds of access to a USB slot on your device.
Not to mention something like sudo rm -rf /* lol. See ya later data. Hope u had backups.
Mr. Robot is such a great show. One of the few series that stuck the landing. With a name like Mr. Robot, the show is not at all what you think it is.
I found it hard to watch due to it's slow pacing. Might just go back.
What it is?
@@MRJMXHD Slow? Really? I loved it. It really takes off season 3 and 4. Stick with it because it all comes together. This show has some of the best directed episodes I've seen on television. The first season is a bit smaller in scope, but becomes a much bigger story as it goes along.
@@MRJMXHD The whole series is on Prime now.
@@NEOREV_MUSIC thanks I will.
Unlike other crime, this is the one that you can stop yourself falling for.
NEVER plug in a USB that isn't yours
10:27 Good good, now do guns.
I made one of these with a cheap raspberry pi Pico and it works amazingly, and it is extremely easy to use, they are really help full when trying to code or set up something on multiple computers because it automates it.
This could be very useful for destroying scam call centers, because you know how much of a plague those scammers are! Create a script that completely wipes the servers and BOOM! No more call centers!
Hak5's stuff is great. They have some amazing tools.
Be right back, pre-ordering my RubberDucky… I mean… uhh for the purpose of setting up my printer… of course 😬
I remember those pop up videos. I always view "calm" videos with unease. :)
The device is double edge swords, in the right hand it could used as tool to help productivity, but in wrong hand it could become potentially tools to harm the network or computer at same time.
Trully depending who is use that, the rubber duck could be become bloody rubber duck or just harmless rubber duck
Wait, but how do we protect ourselves apart from not plugging in usb drives?
dont download shady shit lmao, make sure not too donwload optional packages included with installers
These things have SUCH a reputation for abuse, I actually didn't know what the original intended function was.
Linus said in the video it was to automate software installs as a system admin, insert the key into a Windows machine, and let it do it thing, while you walk away to work on something else without having to babysit a single machine for say 10 different pieces of software to install.
Just realized my passion and finally started pursuing a comp sci degree this semester. And I'm quite proud of myself because I actually understood every single issue you guys listed with the ducky. I love this field haha
The Rubber Ducky and Pineapple are two of the best tools ever created.
I know of one virus that spread through USB, I forget the exact name of it, but I had it both from a school computer and a mobile radio station computer.
The way it worked was: if you inserted a USB drive, the computer had a background task running that would hide all your files/folders, and replace them with shortcuts that both opened the file, and opened the virus, spreading it to your machine and anything else you plugged into it.
Luckily for me, AVG free was able to pick up the virus file on my drive the first time, so I was just stuck with shortcuts for icons (easily fixed with some cmd trickery). The second time I recognized what happened and removed it myself (lucky me I had autorun disabled and the virus couldn't run itself, for some reason).
You can configure any Arduino to act as a HID device, I had this idea some time ago but ofc there's a consumer product for this already 😃
Or a Raspberry Pi Zero.
@@Max_Mustermann A Pi Zero could also run a real programming language for the scripting. (Think LuaJIT)
@@christopheroliver148 Yes, It works pretty well with Python for example.
If you don't need the built in storage, I'd recommend a Digispark USB. It just uses Arduino code, and there's programs that translate RD scripts to run on them. Plus they're like 20$ for a 5 pack. I've been using them for automated thin client setup.
if you find the right deal on Amazon for example you can get them for half of that
Interesting use for automating your PC setup. Have you also tried UiPath process automation?! It can perform way more complicated stuff and it seems easier to setup that this rubber ducky stuff. Nice shoutout to the Konami cheat code, I'm a game dev :D
Why would anyone use an external device to run a setup script, especially one that is so limited? If you already have access to the computer, just put the payload on a regular flash drive and run it...
Or Ansible. This is a neat tool but, for businesses, there are much better options for imaging computers and setting up software. Most software can be baked into the ISO image.
1. Need a full prank video using these 2. Do more Hak5 stuff.
The Writer, Tanner McCoolman, was excellent for this video. As someone that was trained in CySec and learned how to use a USB Rubber Ducky, it was very well explained on how this attack vector works!

I would love to see you do some in-depth vids on the rest of the Hak5 line. I've actually taken to using my old Mark V Pineapple as my IOT access system in my DMZ which let's me rain hell down on bot-net sweeps and the occasional budding hacker that war-drives by for crits and giggles lol.
can u translate those words
@@bro918 he use hacky tools to fight the big bad corporations
This is actually why a lot of businesses will prevent you from plugging in any keyboard except the "certified" ones. I think Active Directory even has a feature for that
We actually still configure all of our work machines with PS/2 ports and you can only connect a keyboard to that port. It’s an annoyance but they was the strategy they decided to go with.
@@GulfCoastGrit I wonder if there could be wireless PS/2 keyboard transceivers. After all, as far as the computer is concerned wireless USB peripherals are identical to wired ones.
This usb stick saved my ass on my first job of manually setting up computers in every classroom, i could plug 2-3 pc at the same time, log in and perform the routine task before lunch break in a single day
Been watching since the earliest of the NCIX days. Great video to let people know about the dangers of things like this. Can't describe how happy I am to see the LTT intro and song making their way back into all the videos. don't know why, just am!
I'm very surprised the ducky doesn't just use an existing language
Might be because of the way it works. It sends signals, as a keyboard.
The way you can program this, could be limiting.
@@matthiasschuster9505 Yeah... But they very easily could make a library for another language that handles all the timings and things. Creating a whole new language seems a bit far.
@Ian Visser that's not quite what I meant. I understand what this device does, but I don't see why a new language was required when a different language with a library would have sufficed. Sure it simplifies the scripting I guess, but it still seems like a lot of trouble rather than making a library.
Props to the Hak5 team. Great group of people
PLEASE do the OMG Cable and the Flipper Zero!!!
Hey linus i doubt this will ever been seen but ive got an idea for a video for you, i recently bought a gaming laptop with an i7 and 3060 and it gave me the inspiration for the idea. The challenge is get every big computer youtuber you can think to chip in a single completely random spec component of a custom gaming pc (good or bad) preferably intel and give it away to a random fan ones the build is complete
Thank you for covering this! I know this is the newest release which is awesome!
Never, EVER plug any flashdrive you find on the ground ever. Who knows what might be on it. Or what device it might emulate
I always do! To be fair, I have an extra shitty computer that is connected to nothing and am not a afraid of losing anything on it. I'm not about to let some e-waste go to waste.
Also I pop them open first to check for caps
I had a college teacher do that to USB stick I left in his class. It was basically empty with just a couple photos on it from when I was in the military I kept it around as a backup, and it fell out of my backpack...dude literally just plugged it into his computer to find out what student left it in his class. He found it and gave it back to me and told me "be careful you wouldn't want to lose one of those with important information on it". This professor was the schools lead as far as like...tech classes. He pretty much ran the IT department..this was at a community college.

VM's could totally be an option. I don't know about Windows, but on Linux using qemu you can pass an entire USB controller to a VM, so if you plug the ducky into a specific port it controls the VM
Ah yes, good idea to send everyone on the hunt for ducky disk images, just to make a stupid jumpscare prank, only to find themselves downloading a tainted version with a backdoor or worse. Will be so much fun. Thanks Linus, for spreading the word.
One time back in middle school my cousin found a flash drive on the school bus. This was well before I even knew what "computer security" meant. We plugged it into a PC to see what was on it. Luckily it didn't do anything. It was just FULL of prawn. Lots and lots of really hardcore prawn. We erased the drive and I gave it back to him and we never mentioned it to anyone.

my 2 Favorite Tec channel cross over? hak5 was my fav in the past with Darren Kitchen and Snubs.... Now Linus is reviewing a Rubber Ducky key? amazing!
I hope the dide taking the usb stick to IT security got a bonus. Hardly anyone does that. Even many IT people would just carelessly plug it in. And that's why social engineering is even a thing. If technical security measurements get better and better, the only weakness that's basically impossible to reliably patch is the user. Humans will always make mistakes. That's why it's more important than ever before to make people aware of those threats and educate them.
I think that devices like this should be legal. The main reasons are
1. Someone will do it anyway, no matter if it's legal or not
2. If it's done anyway it's better to make it public to show that devices like that exist and what they can do
LTT last week: "We would never condone digital piracy"
LTT now: "how 2 hak 101"
At my workplace, the desktops had just the two USB ports for the keyboard and mouse enabled for just HID, and all others disabled. IT are the only ones that can get files off a flash drive using an isolated, disconnected machine with various malware scanners.
