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.
Yeah, this is what's glaringly missing from the article.
Exactly how does Microsoft's device identifier get associated with the ngrok session (normally initiated via its closed-source CLI)?
I can't tell from the article whether Microsoft is doing something underhanded to inject its device identifiers into network traffic, or whether the ngrok client software (again, closed-source!) grabbed the device identifier… and might well do the same on any other OS, using /etc/machine-id on Linux for example.
Since ngrok uses a "freemium" model, it wouldn't surprise me at all if its clients send machine IDs to try to catch users trying to get around its free limits.
> Exactly how does Microsoft's device identifier get associated with the ngrok session
The article has a link to "39-page criminal complaint" PDF, and I'd summarize the prosecution's claims (from sections 21.e, 22, 26) as:
1. The ngrok client was downloaded onto hardware owned by the victims and used by the attacker.
2. The client was later discovered along with an ngrok auth token. (2x0b1363KPV35LCUuZCkJag0G84_2btDjSM5oY82TQuiLZvaz)
3. The ngrok auth data was linked to an ngrok account. (ac_2x0b16MSTJk4PvjLZMoqt4vOvZM)
4. Although a VPN was used by whomever created the ngrok account, the creation-time of the account correlates to Microsoft's telemetry, which indicates that the accused's computer was visiting ngrok sign-up pages.
Unlike the Microsoft equivalent (?), nothing prevents you from scrambling it or outright chmodding to 700 to protect it from prying eyes.
I go further and bubblewrap software that I don't fully trust like Steam on my gaming machine. I simply don't expose /etc at all in most cases. The Linux security model is actually quite weak against potentially invasive software running in a main user account. For example /home is also completely exposed to programs such as games and anti-cheat software.
Adding another example of this is the NetworkID in about:networking#networkid in Firefox. There was a point in time that cause some controversy. Every AI has the wrong information about it's origin and use.
This is the part that isn't clear and is by far the most interesting. At what stage and what point did the GDID get correlated with a tool/web request. As is it almost sounds like Microsoft "telemetry" gathers everything and they did a bulk search for certain activity, pulling the GDID and correlating it with a user.
From reading the official criminal complaint [1] it looks like Microsoft literally logs all web requests along with the GDID and sends it over as "telemetry". It basically associates the URL, the client's IP, and the GDID together.
Or I suppose it's possible that it only sends the domain and not the full URL, but that's enough for the police to go to the hoster and demand logs containing the full URL for said IP.
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.
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.
It was Microsoft Defender SmartScreen in Edge I believe. The visited domain is submitted to Microsoft to check it against known malware and phishing sites. And, as we're learning here, it is associated with the GDID (and Microsoft Account) which can be accessed via law enforcement requests.
> 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.
> 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.
But those companies would have no way of knowing the GDID. It's not sent in a header, I assume.
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".
Converting that ID to hex gives 18,000F,C8CB,93CC which rather looks like 32 bits of random data plus the prefix 0x18000f or possibly 40-48 bits of time in ms granularity from some epoch.
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.
Since you did not understand the point at all: There are regulations in place to force sites to "ask" for permissions to use cookies and track you. The point is that the regulations completely fail to force the sites to not blatantly lie, and wrap the "consent" with "we care".
Yeah, but it's galling we accept these big obvious lies in our society. A legitimate government would impose appropriately stern consequences for misleading and false advertising.
So this kid uses his home computer at his home, and they trace him down with the IP address, and the IP address also makes a request for Windows Updates. And that narrows down the Device ID. The device id is now traced to this kid.
This is the kind of stuff privacy advocates have been raising the alarms about. This is the kind of capability that de facto erased all privacy assertions. And further led companies like Google to take advantage of this and erase assumptions of privacy all together.

I'm probably going to called a lunatic but I'm convinced this kind of telemetry is somehow linked to and behind the huge coordinated advertising push for VPNs in the last few years. More and more, the "invisible hand of the market" seems like literally the hands of a few very large conglomerations of power and capital that shape the economics of the entire market to effectively control it - they shape the gradient and make sure companies optimize loss. VPNs are either directly spyware that increases tracking capability, or are being offered now because they don't need your IP to track you anymore so they might as well make money off your fears while still tracking you. More broadly, I don't see much of a free market or democracy left anymore, now every government is doing a coordinated push to eliminate privacy as well.
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.
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."
The (not so) interesting part is how inefficient it is. Marketing by ads on the internet has less than 0.5% hit or click rate, and even then it is mostly accidental clicks due to the over-saturation of ads. It's not a real economy. It is just simply not actually worth it.
And yet stupid amounts of money are spent collecting detailed dossiers on every person that touches the internet so that... I'm guessing someone's probably trying to sell mattresses or something... because that's always that weird last question in every marketing/advertising survey I've ever seen... do you plan on buying a mattress within the next six months?
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 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?
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 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.
In dbus, it seems the feature is intended for two processes to know they can access the same shmem and other system resources. I'm struggling to understand in which circumstances would that be useful.
I would suggest staying away from Brave. I recently compiled the debloated Brave edition from source and was rather disappointed. Brave was slower on my machine than Firefox and Chromium according to Speedometer 3.1. The built-in adblocker does a worse job at cosmetic filtering than uBlock Origin on Firefox. On top of that, I had to build the browser from source because the only binaries I could find are Brave's own. Their builds aren't reproducible, and no Linux distro packages their own.
If you think I am being paranoid, you may also want to take a look at this:
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...
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…
Tangentially related to Device ID: Apple is significantly worse when it comes to machine identifiers; even with Autopilot enabled you can still install Linux on a Microsoft Surface device (or even Windows if you don't use a Microsoft Account). With MDM locks, Apple devices are literally bricks (especially since all ram and storage is soldered down and locked/paired to the secure enclave chip).
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.
My thoughts exactly. Weren't they just caught recently handing over bitlocker keys (that get uploaded to MS by default when you sign in with a microsoft account) to the feds?[1]
I assume this likely true for nearly all device manufactures. I assume all devices have some kind of unique ID that they use for tracking, whether they said so or not.
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.
You can also use the Windows Diagnostic Viewer to check the telemetry data being shipped to Microsoft. I'd be willing to bet that you could use Edge (with defaults) and see the URLs being sent to Microsoft but nothing would come from Brave, Firefox, Chrome etc.
"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.
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.

Does this not violate European privacy laws?
Probably yes it does. Not that it matters when you hack a website to have some expensive jewelry sent to your home address.
So what if it does? They'll get hit with a fine that will be the equivalent of 6 hours of revenue as they continue to be bastards.
GDPR only covers PII, this is a randomly generated ID that changes on every install on the OS.
You can mix it with other info to track a user, but it's not enough to de-anonymize someone on its own.
If they associate it with a Microsoft account (or anything that is identifiable) then it becomes PII.
And of course they are.
unfortunately under GDPR, anonymous IDs are personal data as they are used to single out a data subject.

On top of that, I had to build the browser from source because the only binaries I could find are Brave's own. Their builds aren't reproducible, and no Linux distro packages their own.
If you think I am being paranoid, you may also want to take a look at this:

Good founders already know this. Bad ones don't care.
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...
Well Enterprises can also enroll Linux machines in intune
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…
Tangentially related to Device ID: Apple is significantly worse when it comes to machine identifiers; even with Autopilot enabled you can still install Linux on a Microsoft Surface device (or even Windows if you don't use a Microsoft Account). With MDM locks, Apple devices are literally bricks (especially since all ram and storage is soldered down and locked/paired to the secure enclave chip).
[dupe] Full Writeup of the Windows GDID

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.
My thoughts exactly. Weren't they just caught recently handing over bitlocker keys (that get uploaded to MS by default when you sign in with a microsoft account) to the feds?[1]
Windows is malware.

Probably a capability demanded through a TCN or TAN as part of a mechanism like Australias Access and Assistance bill.
I assume this likely true for nearly all device manufactures. I assume all devices have some kind of unique ID that they use for tracking, whether they said so or not.
I'm more surprised that this already isn't a known fact. I wonder exactly how far into each device activity is being tracked.

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.

It's Microsoft Defender SmartScreen in Edge.
You can also use the Windows Diagnostic Viewer to check the telemetry data being shipped to Microsoft. I'd be willing to bet that you could use Edge (with defaults) and see the URLs being sent to Microsoft but nothing would come from Brave, Firefox, Chrome etc.
I was under the impression Windows is unreliable for these kind of activities as they are "leakish".
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.
"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.
Worse than just domains as TFA shows full URLs are recorded.
Reminds me of Google Safebrowsing.
Possibly the same but done by Edge?
Truly terrifying. But also shocking that a 'hacker' is using windows
Some hackers want to spend their time doing cool stuff rather than constantly fixing their system
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.
Yeah, that’s why they install Linux
when it comes to video gaming I’ve found Bazzite to be generally far less fiddly than windows 11, surprisingly
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.
This is basically FUD and has been for at least 20 years. Please refrain from it. I am not fixing nothing daily.
