can't hack me, bluetooth drivers aren't working

Me, a Linux bluetooth developer: (chuckles) I'm in danger

why is it that all my Linux tech news comes from this guy, most of the other Linux UKpostsrs are often slow or just ignores things. thanks kenny.

Wait so you are saying that the hacker known as 4chan is going to hack me using my bluetooth?!?!?!?!?!?! Thank God I live in the middle of nowhere.

For those who have a Thinkpad you can dissable bluetooth via the bios, its in the i/o port section of "security" honestly I always have bluetooth turned off unless I want to use my speaker at home

I agree with the rant about bluetooth headphones on the audio quality part, but I still really like them for the convenience they provide

Me watching this while using bluetooth earbuds on my linux laptop. "I'm in danger." Edit: I'm on kernel 5.11, i'm ok for now. Phew

You are right about bluetooth headphones. I bought some wired sony earphones SIX years ago and still working without problem, then I bought some Bluetooth sony headphones thinking "If it has no cable, it won't break" and they broke within 6 months.

What I hate about bluetooth is the latency, especialy when playing games. When watching movies you can tweak the player to add a small a negative delay but it atill annoying.

Hey mental outlaw! If you see this, thank you for making such amazing content!

Love that you mentioned The Pot by TOOL, one of my favourite songs all time!

You're consistent uploads are a really present surprise at the end of the day.

Macbook: I don't need a wired mouse and keyboard I can use bluetooth, look no cables Also Macbook: Check out these dongles I got hanging off of this bitch so I can plug in a basic USB flash drive

HolyC!- I was about to buy a network adapter tomorrow and you upload this...

Goddamit, I spent a good quarter of my day just getting the Bluetooth to work on my Linux distro (Arch btw), and now a vulnerability gets discovered. Ffs.

Been watching this channel for a few months now and I discover you are a fellow TOOL fan, now I respect you even more lol!

I feel 100% with ya on this. My pc is always frankensteined parts and I don't need Bluetooth due to I love everything hard wired. Cable management is a must, but at least if something breaks, easy to repair or replace and don't have to remember to charge anything.

Been using Bluetooth headphones for years without any problems what so ever. Even in crowded places.

About the wireless headphones, it pretty much comes down to how good your DAC (digital to analog converter) is. With wired headphones, the DAC used is the one built-in to the phone. So it can be much cheaper since you are not paying for a DAC, batteries and bluetooth receiver/transmitter. But considering the DAC from your phone cannot be improved, buying a high end bluetooth headphone will usually sound better than a high end wired headphone (when listening on your phone). There are even headphone amplifiers with high end DACs that connect via bluetooth to your phone and then drive your wired headphones. Since bluetooth only transmits digital data, it does not affect the quality of the sound directly. (It does affect the sound if it makes you buy a worse headphone because the bluetooth makes it more expensive).

Me who just uninstalled Bluetooth because it no longer works on my computer for no reason then gets on UKposts to see this But I still use Bluetooth a lot on my Linux laptop because going between classes and moving around at school with wired headphones is a pain

Solid video and quickly released. Thanks.

bluetooth speaker betas: *FEAR* me, a chad who uses a headphone jack like a fucking normal person: laughs in wires

Good video! By the way another problem with most wireless earbuds is also that they are basically physically too small to provide good audio quality. I mean is just made from waves in the air, so a speaker has to oscillate to produce a sound but in those small pieces packed with a battery, an antenna and a chip, there isn't much room to oscillate. So you either loose volume or (even worse) details in frequency. So a pro tip: Just pick over-ear headphones. They provide much better noise-cancellation anyway out-of-the-box. They also don't fall off from your ears as easy without searching for the right plug, module or earbud. They have more room for better speakers and a bigger battery. Now the best thing to search for. Pick a headphone which allows using a cable even if you pick a pair which works wireless. Why, you may think? Because even your headphones bigger battery will become worse over time and maybe sometimes you get too lazy to charge them. So in any case you can still just plug in a cable and are good to go. You can even use them for years. The real question is: Why do not all headphones allow usage with a cable? Why do phones loose a headphone jack? That's the most reliable and highest quality way of listening to audio. It's a physical disadvantage to not provide this possibility.

I love these videos and I've finally been convinced to switch to linux by them and I'm glad to be leaving the bot net that is microwave closed windows

i plugged a bt dongle into my computer running mint 17.3 a few years ago (to transfer files between my phone and comp) and within hours i was getting weird prompts to connect with my neighbors phone! yanked that thing right out, and now i just physically shuttle the micro sd card between devices.. i always thought there was something fishy going on.. thanks for this video!

Dude. I knew you were awesome, and then you mentioned the Tool song. Idk if anyone could be more based.

I'm not an audiophile, but I will be when I find enough information about audio. That would be a great thing to add to my list of obsessions, as someone that enjoys optimization and wants the best of everything.

I think this fits your content style do a video on I2p and more specifically I2p torrenting

Also you should see my cyberpunk mod between a Genius headset (used it's controller) with more accurate Sony headphones and 800mA Samsung battery. Worked an entire day.

Worst about headphones is now you have to charge them. With wire it is a pain what it got always tangled so i was happy to get wireless ones and dont have to deal with tangling issue but charging is even worse. It always happens to be discharged when i need it. I always forget to charge them. So after a while had to return back to ones with wire pain too but less pain.

Thanks for the video man. I use wired mouse & keyboard because I don't want to consoom batteries.

This brings back memories to the pre smartphone era where there were these bluetooth hack apps for the cell phones that could control another cell phone, funny times indeed.

@Mental Outlaw Nice song choice - I knew you were a man of good taste.:)

Getting 0’d from Bluetooth is scary I hope I’ll be able switch back to wired soon enough. I still don’t like my off-brand Bluetooth headset since I got it. Luckily I’ll be heading back to Fedora soon in a few days which will have Kernel 5.10/5.11 from crash prone Ubloatu Focal Fossa with buggy kernel 5.8.0.

The main bluetooth devices I use are: 1. VR controllers 2. Game controllers 3. A little bluetooth keyboard for typing the wifi password on SBC devices that don't have USB ports, like the RetroFlag GPI case. I tried a bluetooth earbuds but immediately ran into all the problems you mentioned. I am absolutely not buying any new phone without both a headphone jack AND a micro sd card slot. I also really really want replaceable battery but I am willing to compromise there. I have boycotted Apple since the iPhone was announced in 2007.

Ooh, so Mental Outlaw is a Tool fan! Love 'em.

What you said about Bluetooth is all well and good, but this seems a bit beyond just that. Glad that they fixed it, my father uses a Bluetooth dac to listen to music with pop os, I guess I will install him 5.11 right away

Whatever happened to RF wireless technology? It still super useful, and in most cases outperforms Bluetooth in speed, distance, and quality. The only downside is you need a proprietary dongle for each device, and in cases with headphones: a freaking mini tower.

tbf, btusb barely seems to work anyway on my desktop it periodically locks up the whole system...

wireless non-bluetooth mouse does make sense tho whip your mouse like crazy in FPS games with no cable getting in the way like logitech's lightspeed mice

Usually you can disable bluetooth via bios settings

Dunno, I end up saving on phone battery whilst using my Sony WF-1000XM3's (if not comparing to a wired pocket amp setup). Batteries can be replaced in minutes and noise cancelling puts them in another league in comparison to wired earbuds when traveling.

Listened to The Pot by TOOL on a pair of KZ-S1D's and a pair of KZ-ZSN PRO X's and while they definitely sound different, neither one sounds worse than the other. This is just my experience, maybe I wasn't playing it in a high enough bit rate to notice or something. It could also just be really close because the KZ-S1D's have a noticeable amount of latency where it could be doing error correction or something.

I've had 10 different wired headphones through the years and every single on of them have broken in the cord or connector at some point. At least bluetooth headphones don't have that problem. Not sure if it's easier to replace a cord or replace a battery though.

For the people that are paranoid about it potentially affecting android (like me) the vulnerability seems to be specifically in BlueZ and android appears to ship with a different bluetooth stack.

i used wired headphones all my life, and all of them broke because the cable got damaged in some weird way. i switched to bluetooth headphones in 2020 and im never coming back

I use bluetooth for my DS4 controller since the shitty micro-usb port is prone to disconnecting. So I guess bluetooth can give life to some things at least

The only reason I use a Bluetooth headset's because I got tired of my earphone cable getting caught on everything and feeling like my inner ear was about to get yanked out. Consequently, I'm usually not too concerned with audio quality as long as it's "good enough".

When there's an issue, it will eventually be patched. This issue was patched in kernel 5.10. The problem with that is that some distros like to stay on old kernel versions, which makes them more vulnerable. Yes, the latest and greatest builds may be a little less stable, but they *will* be more secure. Rolling release is cool.

Bluetooth earphones are very decent for when you're in motion a lot. I've yet to to find a solution to wearing wired earphones that are actually comfortable. Although I care more for the heavy duty types with larger batteries that you wear around your neck. The most important difference has been no snapping cables. Which even on high quality braided earphones happens after a few years... Comparably my Li-ion battery is still going strong after two years and instead the cables of the earphones themselves show more wear.

I use my computer sitting on a couch with a TV like 8 feet away from me. I actually have a use for wireless tech, but I'm still gonna go with USB wherever I get the chance. My dad got bluetooth headphones like a month ago, only just found out I could disable hands-free telephony to make the audio quality not be terrible sometimes.

Your CPU has capability to emulate hardware devices... Such as wifi /Bluetooth cards. Network bridging can take advantage of this and create communication channel that the computer sees as ethrnet

Unless this vulnerability is newer than Linux kernel 5.8, then the CVE for this was patched in kernel 5.9. All kernels before 5.9, however, remain unpatched. Kernels _predating Bluetooth support_ on Linux were _never affected._

BT HID on a desktop home entertainment system, but still not great for gaming as stated above with packet loss.

You can change the battery in "phones with unreplasable battery"

I always felt the same way with bluetooth, right down to it being planned obsolescence. I've always hated this with technology and refuse to use bluetooth unless its absolutely needed for me to watch music (sometimes the cord gets in the way of what im doing) but besides that, I see no use.

I only really find Bluetooth headphones useful for listening to stuff when I'm for example cleaning the house, the cable tends to annoy me so much.

I recently saw bluetooth upgrades in arch linux, I suspected it was some security fix lol

#ToolAverageEnjoyer spotted. Bravo Six, going metal

interesting how my bluetooth keyboard and mouse use disposable alkaline batteries, as opposed to lithium ion. it might kill two dolphins or something every time i change the batteries, but at least they have lasted longer and become fully charged in seconds.

What does this mean for Linux based phones that are out now or in the future?

I use a wired mouse, but a bluetooth keyboard because of convenience. I also KVM my Linux laptop with my other laptop running Windows for convenience. _But_ this means I can keep Bluetooth off in my Manjaro instance.

Bad bluetooth headphone quality is not due to the Bluetooth protocol, Bluetooth is more than capable of sending a high quality audio stream. The issue with BT headphones is the cheap DACs (digital audio converter) that takes the Bluetooth signal and converts it into audio. Bluetooth headphones have many pros, yes they're more expensive, especially to get one that sounds the same as a wired set of headphones, however wireless in some cases is worth it, as well as the headset support that Bluetooth allows.

So currently have the LG G8 thinq. Rec a new phone for 2021 with a headphone jack since LG an hero'd

bluetooth is just very very short range and unsecure wifi. and i don't even use wifi where ever i can use ethernet(90% of the time). i also notices this battery issue as well . we recently bought a motion sensor and the switch is powered by ac but the sensor is powered by battery XD like WTF . if power goes out then the sensor is useless anyways. i instead opted to rig up my own adapter for it that powers it via usb instead of battery.

1. Open Bluetooth headphones with guitar picks 2. Remove PCB 3. Cut signal traces to op-amps 4. Solder one end of headphone cable to the driver input 5. Solder the other end to a headphone plug 6. Connect to the headphone jack on your device (if there's no headphone jack, throw it in the garbage and buy a better device).

Well, time to unplug Bluetooth on my wireless card. Thank you, Mental Outlaw!

Use bluetooth headphones on my desktop because i lost the aux cablr for it. I bought it bluetooth with aux because i wanted to use it when moving around and using it on my phone. Tbh i really like the wireless feeling but yeah this is pretty bad tbh

This resembles the JWZ vs Clem (Linux Mint) discussion about screenlock vulnerability People value the convenience of bluetooth headsets etc, so techies insisting it's bad for security, while technically may be correct, isn't fundamentally very helpful

As most laptops today have anywhere from 1 to 4 type C ports (minus 1 if connected to power), personally (mine have 2 total) I'm forced to use bluetooth mouse. One port reserved for power and another for USB ethernet. Miss the good old days of having minimum 4 USBs + dedicated power connector

The only bluetooth peripheral I think it's acceptable to buy is the mouse, especially if its one that uses AA batteries and a usb dongle instead of bluetooth. Like the logitech g305 that I bough so I can take it with me on the go, it's really nice

Although with how many stripped wires I have from dead wired earbuds I would say those will last only as long as a pair of wireless earbuds so product life is not much of an argument

Totally agree, copper is your friend.

even for a laptop, just get a wireless USB mouse with replaceable batteries. Good news is most bluetooth mice that I have encountered also use regular AA batteries. For now.

LibreBoot Developer Leah Rowe. Suggests soldering your Bluetooth Module as a USB interface. That way it is much more secure.

Just want to say, I disagree with you on almost everything even slightly political, but I still love your videos because you don’t shove opinions into them, and they are such a great resource and very informative.

no bluetooth worries ! I dont let anyone come near my computer. And I prefer that as my "bluetooth protection". Btw ... although I do prefer my wired headset ( very high quality ), I don't have complaints about my bluetooth headset, AS LONG AS the codec is properly configured. And yes, all the high quality music I listen to come from flacs. ( btw Tool Rulez, already saw them live :P )

I agree

Hmmm... My first bluetooth audio device is still alive since 2011... 👀💦...I just need to replace the lithium cell on it. It sounds not great, but it's quite handy. It's quite a shame that the sound quality isn't great yet, especially during voice calls.

my tower is non bluetooth! if needed I got a usb/bluetooth dongle but will never use those headphones...

no problem for me, cant get bluetooth drivers to work haha

Just bought bluetooth speaker a few weeks ago. Fortunately i am with kernel 5.11 on Arch and i am turning bluetooth off with 'bluetoothctl power off'. This approach should be ok and i am safe, right?

People always say that the batteries being lithium ion batteries is what causes them to die so quick, but I don't think that's the case. If you think of the nintendo DS and 3DS systems, those used rechargable li-ion batteries and I've never noticed one of those degrade over time. I can fire up my nintendo DS which hasn't been charged in a year and a half and it's perfectly fine while my old iphone will die if you leave it alone for a day or two

Bluetooth keyboards are quite useful for mobile phones and tablets tbh. Especially if your doing any terminal stuff.

Only Bluetooth device I use on my system is for my PS3 control other than that, the dongle doesn't even stay plugged in.

Nice

This is pretty funny as the Wii mini was deemed Unhackable for nearly a decade and they've barely been able to hack it last year via a Bluetooth exploit that sends a payload to the Wii when it tries to Sync with a Wiimote

I'll be honest, I've actually got some decent bluetooth earbuds with a real nice soundstage. But I'd much rather have a 3.5mm jack though...

The reason bluetooth headphones have worse sound has nothing to do with signal reliability. The reason is bluetooth is a digital signal thus the DAC is in the headphones while jack is analogic signal and use the DAC in your phone. The issue (especially with earbuds) is a DAC in a portable device usually works with small capacitors and batteries due to size limitations. This strongly limit their abilities. However, the truth is a DAC in medium/high ends wireless headphones (which are usually pretty big) is better than the one in phones and thus give as sound as good if not better than same quality wired headphones (probably doesn't apply to computer tho)

are they going to fix bluez so it works or just patch the vuln and further break bluetooth support?

Listening this video with my sony wf-1000xm3 I'm using Artix btw

There are many standards for bluetooth audio floating around and I don't doubt that a good one can match wired headphones. Maybe if you have a 3.5mm jack and the DAC on it sucks bluetooth audio could even be better.

Hm does this mean you could make a root exploit for android using bluetooth that bypasses crap like knox? I have a samsung galaxy a10e and havent really been able to find a root method for it yet, is android effected by this in the same way desktop linux is?

Why? Is this a problem in the kernel? Is this a problem in the firmware? What exactly is being exploited? Installing from image, Bluetooth is on at first boot. Then it’s just a race to see who wins, turning it off or the exploiter.

Make a video about Matrix.

I wonder if near field has the same vunerability

Anyone using a laptop, if you aren’t already using tlp, you can configure tlp to automatically disable Bluetooth on battery when it’s not in use

Welcome to another episode of "Why your Wireless stack is slowly killing you"

*chuckles sensibly in 8-year old midrange laptop* I’m airgapped!

Generally, I would agree with you that Bluetooth is inferior when it comes to listening and focusing in on the music. But you would be amazed at what the mini rigs can do. For anyone who is interested in what I'm talking about search up minirig sound demo
