Hi @nationsquid, I have a question. Is there a service that can delete spam mail automatically or filter maybe?

[@Robdeltonie]

I think I can debunk this once and for all: If the OP said the CD drive stopped working on his MacBook Air, then it's a hoax. It's impossible for a MacBook Air's CD drive to stop working. That's because they never had one. MacBook Airs never had a CD or DVD drive of any kind. It was one of the things mentioned in the keynote where Steve Jobs first announced the computer. So, if that's the first "symptom" of BadBIOS that Dragos Ruiu noticed, then I think it's safe to say the whole thing is made up.

[@elvendragonhammer5433]

I work in IT/security (in software, hardware repair, & programming) Some years a go I did work for a client where a virus spread to 12 of his computers- it was NOT this virus though, if it ever existed. However there was a similarity- wiping the drives did just let it re-install. Started checking to see if it was creating a hidden partition on the HD & reinstalling from there, or staying in memory in an expansion card (there were some similar to this that could hide in your dedicated video or sound card & used it's processor & ram as a staging area to re-infect the system after a re-install). After a bit of tracing I found out the virus was actually in the router itself, & had originally gotten access because the routers access info had never been changed after the factory preset. After flashing the routers bios it wasn't an issue anymore, still tracked down where it came from & added lines into the windows hosts file of the server & router to make sure that it'd never be allowed to try to go back to those IP's or any domain/subnet connected to them. Was a tricky lil bugger for sure, but ultimately just needed the right insecticide- me.

[@NicksLocker]

Wow that is so cool! I was honestly wondering if it had to do with the router. Is there a name for this virus?

[@thatoneglitchpokemon]

Smart of you to suspect the router, good job!

[@elvendragonhammer5433]

I'm sure it has a name, but I don't know what it is. When I encountered it I was trying to fix 12 PC's + the router for a business client that got infected & didn't have the tools with me to do a flash dump of the bios from the router. He'd already lost thousands of dollars in revenue because of the downtime before he got ahold of me. So I didn't waste anytime killing it once I found out where it originated. Might not have been able to anyway- even if I had the tools with me; if it used weird voltages or pinouts, never done one on a router before anyway, so the software might not have worked either as they are usually written for a family of specific chips not just any random one- It would also matter if it was a PROM, EPROM or EEPROM. Some can't read/write certain types as well; sometimes not at all. I also haven't run into that router one again, apparently it was a shiny... Just for reference, even if you did find it or one similar & you let it loose outside of a virtual machine you can be prosecuted for it; even if it was an accident. The good antivirus companies, are like palworld trainers now- they have algorithms that as soon as they find a new virus, malware, trojan, in the wild it automatically contains, analyzes it & usually has a record of the first place it found it right down to the IP address & city. They also track it's spread & how many devices of what type, Servers, PC, android, linux, Mac, IOS etc that it infects & start working on an antivirus patch immediately. That's not including the other cyber security companies or ppl like me who report & upload stuff we come across. Then there's local police cyber crime units & government sanctioned ones too.

It is a fun creepypasta, nothing more. It would require an entire protocol to transfer the virus using speakers and microphone, with error correction and so on. It basically implies that you can control the operating system with microphone (saving executable file and then running it), you would need another protocol for that. Then you have problem of overwriting BIOS from the level of operating system, which I don't think is even possible. Back in the day you would have to run BIOS Setup before OS had even started to update it from the floppy.

[@Mavendow]

Not only is overwriting the BIOS possible from the OS, even the CPU microcode can be overwritten. How? It's called the IME or Intel Management Engine. Yes, Intel's AMT allows for a Ring -3 (negative three) rootkit, but it's turned off by default... Supposedly. We don't really know because the code is secret.

[@ShadowEO]

I mean, Windows PCs have a table in their ACPI allowing one to embed binaries to be dropped and run during Windows boot. (WBPT) But in this case, I mean, Apple has used OpenFirmware or EFI for years, so secure boot and/or their inbuilt boot chain protection would've been a factor for a long while.

"A lot less options to choose from computer-wise in the 80s"? Citation needed! In the here and now there are essentially two basic CPU platforms - x86 and ARM - and while there may be a gazillion motherboard manufacturers the underlying architectures are fairly homogenised (particularly in the x86 world). In the 80s, however, we had a myriad of CPUs - 8088, x86, Z80, 6502, 680x0, TMS9900, etc. - and even computers that shared a CPU would often have wildly different architectures. In the UK in the 1980s we had the ZX Spectrum, BBC/Acorn, Oric, Amstrad CPC, MSX, Dragon, Atari 8-bit, Atari ST, Amiga, PC, VIC-20/C64/C128, Mac, and probably a bunch more I've forgotten.

UEFI and BIOS are still effectively the same. One of which are just easier to use. BIOS itself is a pain but very simple to use and implement. UEFI can be worse, UEFI implementations depend to have firmware bugs, super annoying shit when doing osdev But uefi has a lot of benifits like built-in boot-loader drivers and secure boot. and generally is indeed easier to use as it is a plain C api, every Win32 developer should be familiar with.

[@infinitivez]

a BIOS is the basic input output system and will always run in 16bit (where as UEFI can run under 32 or 64). - I find legacy bugs we used to run into far worse than any UEFI counterparts. But part of me does miss calling INT 13 for a quick reboot.

[@cori11ian]

This is clearly a hoax. The main reason being, as you identified, that any target computer would already need to be compromised in order for the microphone to be enabled and software would need to be running on the OS to interpret the sounds as code. Audio hardware will not operate unless the OS has the correct driver running. That this guy had it isolated in a lab, yet hasn't produced any evidence in over 10 years seals the deal.

[@cyberyogicowindler2448]

The sound receiving backdoor is likely default part of the firmware requested by national agencies. In USA mobile phones are legally requested to contain a similar spy mode "roving bug" in its Baseband OS as official part of their mobile radio standard (i.e. sale of phones without would be illegal in USA).

That bone scanning malware isn't as ridiculous when you learn that HP's excuse for their printers requiring 1st-party ink cartridges is that it's possible for 3rd-arty ink cartridges to contain malware.

[@krissjacobsen9434]

There is one possibility you didn't cover, and that is that the hardware shipped infected from the factory. Most computers are made in China (even MacBooks), and a lot of them are made from OEM manufacturers like Foxconn (even MacBooks). There has already been documented cases of chinese made american electronics "calling home" to chinese servers. If companies like Foxconn is instructed to ship computers and phones they make with infected firmware, they sure can. And then they can lay dormant until some weird code is transmitted via sound. Maybe even embedded into a hit song for all that I know. I believe this to be the most likely scenario, although this story itself seems very unlikely. All of it is theoretically possible, but to actually carry this out in the real world would be expensive and really difficult. Unless you're the corrupt government of one of the largest economies in the world.

About that Bones episode you're talking about: the reason Angela's computer went up in flames (according to the logic of the show, not necessarily real life) is because the virus not only disabled the computer's cooling system, but also disabled any fail-safes against the inital disabling, which caused her computer to overheat. Like you, NationSquid, I dunno if that would actually cause it to go up in flames or not, but I just wanted to add some context to that scene. Anyway, I like that you covered what is essentially an urban legend, while explaining some of the logistics of it, instead of just calling it a hoax and calling it a day.

7:05 Even then, a virus that was programmed to exactly, but **loosely** do that was CIH, and all it ever did was trash the BIOS of specific motherboards back in the 90s. EDIT: It's a very good hypothetical 'computer virus', makes for a great Black Mirror episode. The only thing that really comes close is viruses that are able to backdoor and infect routers and the firmware itself. Though, with TPM and memory integrity being pushed a lot more these days, it's becoming more and more of a hypothetical. From what I know, and someone can correct me on this, but WIndows booting into BIOS mode from the desktop can be done on specific devices still, and so can putting a device into flashmode using an application, but even that would require physical input to continue with the installation from the user, along with a very specific BIOS file meant for the motherboard, would it not?

Sending data thru sound without errors is technically possible. We can use two different frequencies to represent high bit (1) and low bit (0) then add error correction such as hamming code. However, implementing this on BIOS is almost impossible because hacker need to squeeze the required hardware drivers into teeny tiny BIOS storage.

[@cyberyogicowindler2448]

HAM radio operators have their own thing of sound-to-data, called SSTV. They send a ~30 second beepidy-boop through the shortwave band and the receiver, who can be thousands of miles away unter certain circumstances, can restore a low resolution still image from that. Basically you can send memes around the globe without internet. Sometimes even the ISS sends SSTV images, but you gotta plan the reception, because you can only get the signal if the station is visible at "your" sky. But it gets even crazier, a lesser known standard called NBTV whis is even lower resolution, but the image can move like a GIF.

If you know the fact that modern GPUs, even in the budget class, don't come without hardware AI features. Viruses based on it are very real. We need to wait a little while until users have more common PC's like that. Of course this is one possible scenario that could happen in a crazy minority - but it is very real.

Most phones _are_ constantly listening for "OK Google" or "Siri". This could serve as an attack vector if you "spoke" a malformed sentence or something.

[@SergeyVikhlopov]

The presentation of this video gives me some good old tabloid vibes. Had a good laugh, haha)) That said, this virus is somewhat plausible. At least in theory. BIOS have access to wifi and bluetooth hardware, so once it has taken control of that it can potentially spread itself through those networks onto other computers. At the same time though, the level of sofistication of a malware like this is unimaginable. Storing something so powerful on a very limited resources of a BIOS ROM doesn't seem possible for something so underpowered as macbook air. This one seems to be fake, but with some tweaks it might be a good script for a halloween horror story aimed at IT audience!

[@taylorwoolston8856]

I'm not a professional computer scientist or anything, but even I know this is total baloney.

[@annoythedonkey]

What if you created a virus that made itself look like a device that presented itself as a WiFi network?

[@cyberyogicowindler2448]

​@@annoythedonkey Because privacy and brain protection aware people refuse to use wifi at all.

[@hypnos4754]

The definition at the beginning is for a worm, not a virus but the term “virus” is often used interchangeably with “malware”. A virus inserts itself into an existing program or file.

[@MrGrimm73]

QR code gold! Good one, I'm glad curiosity got the best of me. 😉

[@yoshiyajoshuakiryu3198]

I worked in the government as an it tech. We had a virus that made the computer “sing”. We had to flash the bios and low level format the drive. So it did exist. And I hated that. We lost a lot of data because users refused to save to network. 😂 Luckily, he was in a very well shielded office using…Windows ME. Yeah. I know. 😂

[@witchywoman2008]

I’d never heard of this before and now it is going to consuming my every waking thought for the next month.

[@fr33bird7891]

Love the shirt!! Halt and Catch Fire is so underrated.

[@TheHeart_Autistic]

WE GETTIN OUT OF THE COMPUTER VIRUS WITH THIS ONE ‼️‼️‼️💯💯💯🔥🔥🔥💥💥💥🗣️🗣️🗣️

[@RogueCarrot]

MacBook Airs don't have optical drives. Never did. Even when Macs still had optical drives. That right there would be enough to discredit him in my eyes. lol

[@TeagueChrystie]

This is fascinating. I didn't know you could affect BIOS this way. Jesus.

[@Greeem]

bro its not real. the source of the story said his cd drive on his macbook air stopped working. macbook airs never had a cd drive. literally the first "symptom" is impossible for the device he was using.

[@bullets4luv]

If anyone was wondering, the QR code leads to a Beatles song. I'm just happy it wasn't a Rick roll or the Josh Hutcherson edit.

[@coffeecat086]

The first thing I thought of when you spoke about the transmission through sound was that you would have to turn the microphone on in the first place, aside from all the other technical aspects, that’s the bit that seems off.

[@th3fish]

You do a great job explaining such complex topics

[@TheCinemaMan777]

Love the Halt and Catch Fire shirt! Not enough people watched that gem

[@FragileJesseLord]

16:57 The QR code is still readable! Thanks, error correction :D

[@AndyMacs]

16:56 Dog this is one of the many reasons why I love you

[@derrekclay7425]

Nice Green Day reference @10:19. Kudos, sir.

[@TheSayuVA]

You know it's a great day when a new NationSquid video drops!

[@vizthex]

i was waiting for a door to pop up in that intro while you said "welcome to the twilight zone" or something lol

[@UnrealVideoDuke]

Not the first virus to spread through the air. Older cellphones were retransmitting a virus that was only known to drain the battery faster because it turned up the antenna gain way before this instance. I was previously laughed at by an IT technician after I told them that I had seen a virus hit my PC's BIOS. Anything that is programmable can be volatile. Your "UEFI" works at a High Level. Most viruses that affect the BIOS are at a Low-Level which some are programmed to inject code into the host OS. They can even reach internet channels if they are programmed to do so. Low Level programming is well ahead of any of the brains of any educated programmer of today because they were never taught to utilize it. Most programs run on 3-5 tiers of High-Level programming and will be infected if any lower tiers are affected in some way. Ok, I'm rambling... For your "Air Virus". It is known that some CPU's have an address volatility problem where if an instruction was sent to an address it would execute it. The sound of a computer is controlled by a DAC and that DAC communicates on a CPU BUS. If a certain set of instructions were to leak past where the CPU would mistakenly run the code it would become infected. The code would not have to be majorly complex. Just the code would have to act if it was part of the CPU bus to be executed. It would literally bypass the OS, UEFI and BIOS directly hitting the CPU. The code itself can be smaller than this following string of text... "Open sound device. Transmit code. Save code." It could be more complex but not much needed to be of any great size. We are talking about bits and bytes here working at the lowest level where you only can see the highest level unless you have the tools to read each instruction as it happens which does need specialty equipment

[@cyberyogicowindler2448]

Early AMD K6-series CPUs had a bug that could crash them by reading certain bit patterns (even within e.g. a jpeg picture) and so caused mysterious lockups. I don't know if this could actually execute code, but if the bits came decoded from audio-in (I very much doubt that it is possible without CRC error correction) it hypothetically might be possible to be fooled to execute arbitrary code only played as sound into a microphone.

6:28 malware can exist in the hard drive’s firmware persisting after wipes

[@s0men00bb]

You forgot hardware instruction sets , hardware abstraction layers which are essential for any computer , then error checking and correcting etc which are all hardware based as well as software , you can implement AES-NI instruction in software if your hardware supports it , just like the TPM thing now. Then , there are metadata that OS uses to identify stuff , not much nowadays , but in past it was very important. In early days of computing , and even 10 years from that story , you had issues if your program was x86 based that it wont run on AMD , and so on , list is long , but you can perfectly do it on platforms like Raspberry Pi , Arduino and similar , as hardware and firmware isn't so smart , it interprets machine level code as it's thrown at it , without asking many questions. You can dig deeper in JFIF and EXIF exploits as they are very basic example on how computers interpret things. DOS prompt wont prevent you from killing entire OS if you told it do so , nor will any other interpreter as long as it understands what it receives.

[@vrclckd-zz3pv]

My phone can read the QR code at 16:56 perfectly line. The QR standard includes error correction bits for when a QR has been partially occluded.

[@thatoneglitchpokemon]

It's hilarious that nationsquid has no idea about this when there are 5 comments about error correction

[@dpennington19]

The vocal fry on this man. This is the voice Malware would speak with.

[@y2keef]

Always a pleasure to see the Squid Kid! 😍

[@stuffz4040]

I mean as a 2000s kid, these virus lore are a lot better than the sonic.exe tech horror I was brought up with

[@ynotw57]

This reminds me of the Rhythm Nation HDD failure situation.

[@hackaboom]

Fun fact you can use sound to break encryption in your cpu. Sounds wild but basically anytime something(electron) is moving its gonna move stuff around which will make sound in our atmosphere.

[@ningayeti]

You almost figured it out when you mentioned Stuxnet. Yes; if it exists the only entity with the cash, brains, and manpower to pull it off is a nation state. Additionally; a vector alrrady known to be vulnerable are the video bios' of certain manufacturers leading to the possibility of a system bios being infected by a video bios

[@iamlorddems3859]

It might just be a challenge wrapped up in a spooky story

[@stevo911]

Tape data and shared programs over radio and phone back in the day would be a good example. Remember getting games over phone calls and fn radio?
