BLUFFS: #Bluetooth Forward and Future Secrecy Attacks and Defenses
New BLUFFS attack lets attackers hijack #Bluetooth connections https://www.bleepingcomputer.com/news/security/new-bluffs-attack-lets-attackers-hijack-bluetooth-connections/
Eurecom-Forscher, u.a. Daniele Antonioli, haben auf Grund zwei entdeckter, architektonischer Schwachstellen in Bluetooth sechs neue Angriffsszenarien entwickelt, die unter der Kennung CVE-2023-24023 firmieren, die Bluetooth Core Specification 4.2 bis 5.4 betreffen und auf den Namen BLUFFS hören. Möglich sind dadurch Man-in-the-Middle-Angriffe (MitM) und Geräteübernahmen.

Tutto bellissimo... se sono in casa da solo
Ma se volessi vedere qualcosa insieme ad un altra persona?
So bene che col bluetooth puoi connettere 1 sola periferica audio per volta, quindi vi chiedevo: esiste un qualche accrocchio per poter collegare 2 cuffie contemporaneamente?
Tipo un hub o cose simili?
One of examples of endless #enshitification happening across digital landscape is how actually people are being pushed away from #bluetooth towards using something that require internet connectivity. Have you tried to load files from a phone to PC without a "Phone Link" thingy, via standard "send file" / "receive file" of Bluetooth?
Microsoft wants people to register phone devices into Microsoft accounts.
I don't like how deeply buried "receive file via bluetooth" at windows into Settings app.
Or look at this nice project: DIY Bluetooth Speaker in a Walnut
Which idiot thought that multipoint #bluetooth support in a headset is fine with supporting two devices ?
Mobile, tablet, work and private PC.
And a headset that is all the day in pairing mode, sigh.
These €5 sensors are great! They are much more sensitive (and have better range) than #PIR sensors, plus they detect both motion and occupancy.
Now, the end of the story is that I'm going to buy #Bluetooth dongles for both our PCs now. It's not the quickest, at least I think so, but it works.
Now, why the fuck is is downright impossible these days to send files from one device to another?!
And yes, I know #Apple, #Google and probably #Microsoft all have their own versions of AirDrop, Nearby Share, or whatever they call it. Guess what? It only works within their own fucking ecosystem. Wanna send a file from an #Android phone to a #Windows PC? Well, tough luck, you should've bought an Android PC. Oh, right, THAT DOESN'T EXIST.
It's fucking 2023 and we have computers writing articles and painting artworks but the only(!) technology that can transmit files to another device in the same room is fucking #Bluetooth?
Bluetooth-Zukunft: Google mischt jetzt als Promoter mit

Bluetooth could help police spot e-bikes hacked for higher speeds | Senior German cycle-industry wonk calls for Bluetooth-based tracking of E-bikes
So there’s apparently debate in Germany that e-bikes are being “tuned” by some miscreant law-breakers to exceed speed & power constraints built into them by manufacturers and German law. This happens, and can have bad consequences for the bike let alone the rider, but in the sledgehammer-meets-nut way of political regulation:
Ernst Brust […] has recently been pressing for e-bike motor manufacturers to incorporate Bluetooth interfaces, “to make it easier to identify manipulated motors.”
Brust is no lightweight: variously an industry analyst, founder of a human-powered-vehicle test laboratory, managing director of the German bicycle industry association, and now on the board of Rohloff, he’s not a crank (ha!) to be dismissed.
What he’s proposing is that all e-bikes essentially broadcast their power ratings via Bluetooth Low Energy (BLE) and incidentally thereby providing a digital license-plate for every e-bike… and who knows what other features.
From the freewalled posting that road.cc rewrote:
For Ernst Brust e-bike motor manufacturers should use Bluetooth interfaces to make it easier to identify manipulated motors. He recently participated in the battery technology conference organised by the Criminal Investigation Department in the city of Würzburg, Germany. He told the audience of the conference that a Bluetooth interface would make it very easy for the police to find out whether an e-bike has been tuned or not.
“If the police can read via Bluetooth that the output of an e-bike motor is more than 12 watt hours per kilometer, then the motor is tuned. The normal output is 5 to a maximum of 10 watt hours per kilometer,” said Ernst Brust. “Due to the variety of tuning kits, proving whether a motor has been tempered with or not is very time-consuming; you have to open the engine and require specialist know-how. The interface would greatly simplify everything and contribute to security.”
Speaking to the UK market for the moment, the politicians and police and polity here are already so much anti-cycling that I suspect they will seize upon this idea even though, over here, it is far from being a significant issue for the police to deal with.
Of course we are already in a world where many vehicles are equipped with a massive digital footprint, from onboard-wifi to tiny chips that chirp the individual tyre-pressure to anyone and anything that cares to listen. Many, perhaps most of our vehicles are passively digitally trackable.
But putting a Bluetooth API on your bicycle is a pretty scary Rubicon to cross, for privacy and freedom.
Today I learned that game controllers can be used to replace your #Android TV's stock controller.
I was searching for an affordably-priced #Bluetooth-enabled controller for my #Linux PC and discovered this amazing fact.

Anyone here had any success with HC-05 Bluetooth modules ?
I received this one a few days ago and can't get it to go into master mode. I've done the usual recommended things such as pulling pin 34 high (3.3 V) and it just doesn't respond as normal HC-05 modules apparently should. AT+INIT never responds, for instance. No matter what commands I send to the module, it won't go into master mode but always remains "pairable".

I expect #Apple to rush a fix for this issue, as it only affects iOS 17.1 & I believe the beta for 17.2 as well. Prior iOS versions are not affected (just the 17 series apparently).

Aktuell halte ich nach ein paar günstigen Außenthermometern Ausschau, die ich an meine Home Assistant Instanz anbinden kann. Dabei bin ich nun auf SwitchBot-Produkte gestoßen, die sich per Bluetooth mit dem Raspberry Pi 4 koppeln ließen.
Der Hersteller gibt 120 Meter Reichweite an - im Freien, ohne Hindernisse. Das erscheint mir recht viel, wenn ich mir anschaue, auf welch kurze Distanz die Armbanduhr und das Smartphone sich via Bluetooth oft bereits nicht mehr finden …
Hat jemand Erfahrungswerte, auf was sich die versprochenen 120 Meter reduzieren dürften, wenn zwischen Sender und Empfänger mindestens drei Wände liegen?

@nigelbyrne Other people I know tend to #Spam #Bluetooth so hard that ebery device around them gets the message to "tell that antisocial asshole to turn down the volume!" and liteeally play that with a cringy TTS voice on endless loop to all bluetooth devices in range.
Making everyone hate the wanker that made someone else make Bluetooth unuseable has a 100% success rate IF and only IF one ceases said spamming as soon as the desired ibtervention takes place...
Fun with home automation: created a Bluetooth proxy so Home Assistant would pick up my Inkbird BBQ thermometer. (Which worked fairly well!)
Ended up picking up the neighbor's Bluetooth toothbrush.
1.BLE has a much longer range than you'd think, so be careful what you're exposing unpaired.
2, Why does a toothbrush need Bluetooth?
3. Home Assistant will happily integrate with your Bluetooth toothbrush.
Dear God, but the Sony ones were always so brittle. Seldom had one that lasted more than a few months. Then again, I was rather rough with 'em, always tossing them into my backpack while out and about.

Every Bluetooth device I own connects to my Android phone without a hiccup. Every Bluetooth device I've tried (a subset of the first group) works without a hitch on the Windows machine at work.
But my main Linux box at home? About half of them don't work.
It should be a fucking embarrassment, but it seems the F/OSS crowd doesn't "grok" shame.
This #Bluetooth issue in #macOS / #macOS14 #Sonoma is really killing my productivity. I’ve never had my Mac lose connection with a keyboard before, but since upgrading to Sonoma, BT keeps crashing multiple times a day. I tried all the suggestions in all the forums, short of calling Apple’s support, I tried everything. But they’ll just tell me to reinstall macOS to test if that fixes the issue…
I've had a #Jellycomb #bluetooth #keyboard for #Mac for a few years now, worked great when I first got it, but some macOS update broke the media keys on it (in fact anything on the top row: media, screen brightness, fn keys, etc.) and I couldn't find a fix at the time, so kinda lived with it.

Music from my phone playing on the BT speaker. Perfect volume. Very pleasant.
Suddenly, a sleeping Mac in the household decides to:
1. wake up
2. connect to the speaker
3. drive the volume all the way up to 11
5. go to sleep
I almost get a heart attack, while scrambling to get the volume down.
How is #Bluetooth still so shit after quarter of a century? 🙄
Why do hardware manufacturers feel the urge to fuck up user assumptions (like: "sleeping device won't randomly connect")? 🤦♀️

Possibly due to the #PC I've paired with them being in range - getting them to connect to the PC at all is a fucking nightmare, requiring me to disable Bluetooth on every other #Apple device in range.
That *might* be the fault of the PC’s USB #Bluetooth adapter (it's hard to find reputable ones online), but either way: improved AirPod connectivity? Not in my experience. 🙃
In "so it turns out I owe #Bluetooth (protocol) an apology", as a "shit I can only get something on Amazon :ac_sighing: and I need to add something for free shipping" I picked up what is apparently the only Bluetooth to 3.5mm headphone audio receiver with battery power in a clip format, the APEKX Clip Audio Adapter.
And for a cheap SBC codec device plugged into my favorite $20 wired headphones in a form factor you can't get anymore it sounds... fine? The build quality isn't great, but for a six letter garbage brand thing, hey, apparently unique market segment so good on them.
This does mean my eternal annoyance at every cheap Bluetooth headset/headphones sounding like crap is on them fucking up the headphone part, which is even more infuriating. :ac_resignation:

Better Bluetooth Sound Quality on Microsoft Teams in Windows 11
Here's the problem. The current Bluetooth spec doesn't allow high-quality audio to be sent to a headset when it is also sending audio from the microphone. Instead, it switches to the Hands Free Profile (HFP) which only streams low quality mono sound. It makes Teams calls sound like garbage.
The usual solution in Google Meet, Zoom, and MS Teams is to manually tell the app to use Bluetooth for speakers but a separate mic for input. In my experience, that never works with Teams. It forces HFP even if you choose a different input source. Or it cocks-up the sound somehow.
So here's how to fix it on Windows 11.
Open "Settings" and click on "Bluetooth & devices" and select "Devices":
Then scroll down and click on "More devices and printer settings":
Right-click on your Bluetooth headset and select "Properties":
Open the "Services" tab and un-tick "Hands-free Telephony":
Hit the "OK" button to save your changes.
When you next use Teams, select your Bluetooth headset as the speaker and your laptop's mic as the input. You'll have beautifully clear sound while listening to Barry from accounts talk about this quarter's EBITDA.
Yesterday, I asked my #iPhone to forget its connection to one of my laptops because my calls were being routed over #PhoneLink when I didn't want them to. Since then, every single time I get a completely unrelated pair of #AirPods out of their case, my phone refuses to connect to them without toggling #Bluetooth off and on again, including after a restart of the device. Obviously, I'm completely thrilled by this development. My new phone cannot arrive soon enough.

Here is an excerpt from the show:
The protocol is insecure, doesn't work and has been shit since about ... 20 years.
All I want to do is call my girlfriend and say "I Wub You" but nooooo. [Literally all I wanted to do.]
Sync-ish to her phone, tunnel sounds.

I FUCKING DESPISE #Bluetooth.
I can't call my better half without fucking about, She has to connect her stuff to her phone, occasionally to her car,
The BT5 specification is garbage with broken security in a spectrum that's overwhelmed and under managed by the FCC.
I can't hear my better half because, headphones (her's or mine depending, they both suck) (I really hate her headset, she hates the set I just fucked up.)
For months, when playing audio from my #iPhone to #Bluetooth speakers/devices, the #audio would pause every few minutes, seemingly at random. I could not figure it out. I thought it might be a background app that was mistakenly taking over media playback, so I’d force quit any potential culprit or even restart my phone. Re-pair, reconnect, reset. No luck.

I’ve been using my #Ruimen AJ01 #Bluetooth sunglasses for a couple of weeks now. I still like them, but I must admit the sound volume isn’t as good as it could be. In a noisy environment, I’ve sometimes struggled to hear #Voiceover. All audio frames have this problem to some extent, but it is still disappointing. Then again, at less than half the price of the likes of the now defunct Bose & Anker frames, I suppose you get what you pay for. I do still like these frames, but I do wish the volume was a bit louder.
Few months ago I dumbed-down my setup of home speakers. From WiFi-connected, cloud-enabled #smartSpeaker. To simple #Bluetooth one. And I have to say that it's such a relieve. Not because of surveillance capitalism. Can't care less for that one. But because things finally work (mostly) without a glitch. No need to double guess what stopped working, where. What disconnected. What service need re-authorization. How to route sound from one device to the other.
It. Just. Works.
I would never, ever think that I would be happy about dumb, BlueTooth devices.
Apple isn't "winning" through merit and building better products.
They're playing dirty, and Airtags are another example of this company bullying the market.
We ALL Suffer When Apple Products DON’T “Just Work”...
