I was a big fan of Microsoft ten to fifteen years ago. I’ve since transitioned my whole family off Microsoft products now over to Linux, Apple, and proton. Edit: and Brave.
I really thought their corporate culture would’ve changed after the late 90’s but I guess this is a good lesson for founders. The culture you build into your company will likely outlast your tenure.
I went to check if Flatpak would protect against this but it seems although it's a wanted feature it's not so straightforward to implement: https://github.com/flatpak/flatpak/issues/4311
I don't like the idea of a persistent id for my machine. Would there be any harm in rewriting the machine-id at every boot? Or just deleting it as part of the shutdown sequence?
Whatever you do there will always be uniquely identifiable information (if not an id, a fingerprint) on your machine.
If you want to escape that, you have to use dedicated privacy-enhancing tools / browsers, but even then, it's very likely that you can still be identified by motivated adversaries.
It doesn't mean you have to give up, but, if such id is necessary for technical reasons in systemd (I guess it is), I wouldn't worry too much.
This sounds like you're referring to state actors and intelligence agencies, but really this applies to the entire advertising/surveillance industry of people trying to sell you a new flavor of soda.
Sure, but the problem then is not systemd machineid, but rather the browser reading it and making it available for such identification (don't know if there is a browser out there doing that though).
Unless anonymization is provided by your browser, there is nothing you can do to prevent such identification technology run by these advertisers to build your profile, and send you targeted ads.
And petty criminals that set up fake fake websites to steal your money, ad-networks are also commonly used to spread malware so limiting the number of attack surfaces is the only sane thing to do.
The DUID is designed to be unique across all DHCP clients and servers, and stable for any specific client or server. That is, the DUID used by a client or server SHOULD NOT change over time if at all possible; for example, a device's DUID should not change as a result of a change in the device's network hardware or changes to virtual interfaces
I have the urge to grab a pitchfork, but I know better than to make assumptions about why that functionality was added. Time to do some homework I guess.
The utility of and presence of unique identifiers in software should be no surprise.
But if you are using TelemetryOS (i.e. you cannot fully switch off the chatter) and your daily Web browser doesn't offer privacy extensions, you are the product.
Nope, but Debian does use systemd by default so it's there.
I'm running Arch Linux and /etc/machine-id is present.
There's also an optional /etc/machine-info file that could exist. It's not a part of systemd and won't be created by default. It's more of an informal way to have details about the system in 1 spot. It was more popular when provisioning bare metal servers but still has value in the cloud. You can have key / value pairs on who to contact, where it's located, what type of machine it is, etc..
I remember a long time ago intel tried introducing unique IDs for their processors. People got up in arms made a big stink and intel put its tail between its legs. Many years later, the industry through a thousand little cuts has that and more with merely a whimper because it’s not a single big boogey entity but it’s diluted across hundreds of thousands of developers who deployed a myriad ways to fingerprint their users…
Aww you missed the Ballmer Years. Chalked full of "me too!"'s and broken promises. But he was right about one thing. Developers, developers, developers...
The interesting part is not really the existence of a machine identifier. Almost every modern OS has some equivalent. The bigger question is the boundary: which components can access it, and when does a local identifier become a remote tracking identifier? A machine-id sitting on disk is very different from an OS vendor correlating it with network activity.
I guess we’ll see a Windows tool that sets your identifier to this suspect’s “g:6755467234350028” very soon (weird ID, by the way. 16-digits makes sense, but I would have expected it to be hexadecimal)
Also, can anybody tell how “Microsoft had records showing that on May 12, 2025, at 19:21 UTC, the GDID associated with Stokes’ computer “accessed, among other ngrok pages, 'https://dashboard[.]ngrok.com/signup,'” works?
If it’s the browser sending that info to Microsoft, wouldn’t somebody have noticed that their PC contacts Microsoft for every web page they open? Or do they batch that data and send it at some later time?
Also, would that mean this ‘only’ affects those using Microsoft’s browser (or does Chrome do the same, sending data to Google?)
Alternatively, is this happening lower in the stack? I can think of a place where a system component has access to the domain name, but not of one where it has the full URL.
A non-Edge browser would give the OS the domain name from the HTTPS connection and the page title because that's what it sets the window title to. I think that would be enough to identify the URL in a lot of cases (i.e. the sign-up URL sets the title to "ngrok Sign Up".
> Also, can anybody tell how “Microsoft had records showing that on May 12, 2025, at 19:21 UTC, the GDID associated with Stokes’ computer “accessed, among other ngrok pages, 'https://dashboard[.]ngrok.com/signup,'” works?
That URL shows 16 blocked requests, it tries to load (at the very least) datadog and googletagmanager, I'm guessing the police simply reached out to all the analytics companies Ngrok ends up indirectly/directly sending data to, which ends up saving everything they get their hands on.
What surprises me the most is that the guy was using a Windows installation to do all of this. But then again, you only hear about the dumbest criminals who get caught, so I guess it does make sense after all.
This goes a long way to prove that Microsoft does NOT care about your privacy, even if the header of their cookie consent claims so. They absolutely do not care, and this should be said about every big-tech vendor, not matter how lame it seems to say so. It is long overdue that we all say what needs to be said: they do not care about your privacy, your independence, or your well being. They DO NOT CARE.
To me this indicates that Microsoft has some sort of traffic analysis performed on endpoints, then linked to GDID. I'd guess this is part of Defender's real time protection or MAPS.
Fun fact, Microsoft Defender MAPS was previously named SpyNet.
The GDID identifier seems software in nature though. They could be more aggressive and tie it to the baseboard's serial number the way some games do. Then the hardware is tracked throughout its entire lifecycle, not just per instance of Windows install.
that's the idea behind SecureBoot and the TPM chip is to provide the GDID based on hardware fingerprint. Some games already do this as "anti-cheat" measurements (tracking you) and Microsoft has been doing it since Windows 7 days. It's just that the TPM now gives you that hardware authority.

Why when Americans do something do we feel like we have to mention the Russians and the Chinese?
Maybe I'm just bad at PR, though. If we call this "Chinese" behavior, maybe it will appeal a particular demographic who would normally support it in order to protect them from "Black Crime."
There was a time where the default assumption was functionality created tracking opportunities. Nowadays, it's more the opposite. Social media have always been on the forefront of monetizing data, but the same data in the hands of governments is used differently. My point is that the way you/we feel towards Facebook, the entire world is increasingly feeling about most, if not all, US tech.
I know people who won't use Israeli or Chinese-made tech for fears of sabotage. US tech is quickly making its brand in that market.
I know people who avoid US tech and happily use Chinese or Russian tech here in central Europe. Not trusting US tech isn't new, it just gets a lot worse
I actually opened a yandex mail account 15 years ago because, since I was going to be tracked, at least it would be from people who have no friendly contact with most gov entities and companies in my society.
I heard same argument with telegram (however I wouldnt consider it to be Russian tech these days) but yes. Choose your poison, basically. And some entities definitely seem(ed) less evil to our society than others.
My surprise level is at approximately... zero.
Next we will see some news, that MS was compelled to share that info with some three letters. - Oh wait, that is exactly what has already happened, according to the article.
MS is just like that person, who drives a dagger into your back.
I switched to linux a year ago and in that year had less problems than on Windows.
I had some minor problems after updates once or twice. On Windows i had to boot into restore mode multiple times due to Windows Update screwing something up.
The MS Store also constantly had trouble updating apps and games and i had to manage packages manually and uninstall and reinstall them so it would work again until the next update.
The times were Windows is easy to use and fire and forget are long gone. The decline in quality is noticeable.
Actual hackers don't need to run debloating tools each boot getting tired of all the adware and bundled crap eating GB's of storage.
Actual hackers would use Guix System and actually hack really cool stuff and, yes, Guix (the package manager) would be eating GB's because of reproducibility... but at least you could restore your system from Grub anytime.
TLDR: Microsoft can (at least) correlate your Windows installation to all website domains you visit while using Windows.
It's unclear what the mechanism is, but I'd wager their "telemetry" is constantly revealing your installation ID, your current IP, and domains that were recently resolved.
The article links to this page, which was shared on HN yesterday. [1]
I feel like using wireshark to look at what's being sent back and forth from Windows telemetry, when using Edge, Chrome & etc should reveal what's being sent and recieved. Using MITM SSL spoofing should be able to intercept the packets.
I would be shocked if Microsoft was not using their own layer of certificate-pinning to stop people from doing that, and/or using another layer of encryption separate from the networking layer.
Only way to see what's going on is testing to see what's going on. Hopefully, someone who knows more about it than me can take a look at the packets and see what they contain.
"all" would be troubling indeed. I hope that someone can discover the mechanism, and whether it's depending on any settings like "Share browsing data with other Windows features" or any other settings.

The number of things you need to try to keep track of merely _improve_ your privacy is maddening. The whole world seems to be against you.
If you want to escape that, you have to use dedicated privacy-enhancing tools / browsers, but even then, it's very likely that you can still be identified by motivated adversaries.
It doesn't mean you have to give up, but, if such id is necessary for technical reasons in systemd (I guess it is), I wouldn't worry too much.

Unless anonymization is provided by your browser, there is nothing you can do to prevent such identification technology run by these advertisers to build your profile, and send you targeted ads.
The OS could treat certain apps as untrusted and spoof or limit the access to these unique identifiers.
Double-check that this method actually works though.
Machine ID is used for things like dhcp leases, log rotation, etc. IPV6 addresses or transient MAC addresses are derived from it
The DUID is designed to be unique across all DHCP clients and servers, and stable for any specific client or server. That is, the DUID used by a client or server SHOULD NOT change over time if at all possible; for example, a device's DUID should not change as a result of a change in the device's network hardware or changes to virtual interfaces

You can mix it with other info to track a user, but it's not enough to de-anonymize someone on its own.
And of course they are.

I imagine it's not too difficult to narrow down the potential suspects with how much data points you'd get from ISP, Windows telemetry, and whatever.
Reminds me of Google Safebrowsing.
