> Note that, Microsoft had already flagged Stokes to the FBI once before, in an October 2024 criminal referral describing “online services telemetry.”
I don’t like the idea of Microsoft taking it upon themselves to proactively report what their customers are doing to law enforcement. I guess this makes it unwise to use Windows to i.e. look for information on where to get an abortion if you live in a red state.

What isn’t clear to me is how they’re able to say which GDID visited each site and when.
Did the hacker not disable telemetry? Was he using Microsoft Edge? Or is it just a GDID->IP mapping combined with network activity?
It is obvious that Microsoft has an identifier for my device. They enforce license activation.
The problem is that they’re tracking user activity and associating it with this ID, even for a user who, one would assume, rejected all telemetry.
Can they do this in devices owned by companies and governments that are configured with strict no telemetry and no cloud services policies?

This isn’t the pre-Win11 hardware license identifier that we already knew about. This is the “Microsoft Account identifier” that Win11 forces an association with for every install and activation of a Windows 11 hardware license. Presumably that identifier also exists in earlier versions of Windows when using Microsoft Store, or Office, or Sign In With Microsoft Account — but those were things one could opt out of. If the prior hardware license system could be so trivially linked to people, then Microsoft would be behaving like Oracle and issuing pay-or-else demands to millions of end users worldwide; they have not. The news here to me is that Windows 11 has now been proven publicly to correct that oversight, and can begin targeting specific individuals both for law enforcement and for corporate profits.
It's very naive to assume that they wouldn't collect and report the telemetry regardless. Filtering then bundling and compressing the data while staggering the calls back home. Any outbound traffic to Microsoft could be injected with that data, and redirected once it reaches.
>Microsoft’s records showed that at that exact same minute, a Windows device carrying GDID g:6755467234350028 had visited the ngrok signup page. Three hours later, the same GDID visited the retailer’s own website, through the same Tzulo proxy address used to set up the ngrok account.
Can someone explain the mechanism through which Windows sends this information to Microsoft? Did the hacker use Edge, which communicated the web history + the GDID of the user to Microsoft, or is Windows snooping on browsers besides Edge and sending the web history to Microsoft, or is Windows bundling a summary of all connections open and sending it to Microsoft?

It's "Connected Devices Platform" telemetry bullshit.

None of it says how the GDID was associated with browsing history. It says it’s associated with a Microsoft account.
Why did Microsoft have his browsing history? Was he syncing it from Edge?

Apparently only some aspects can be reduced and the mechanism is also in Windows 10.
the GDID seems like a tertiary issue barely worth mention, like ok a hw identifier exists in web browsing logs that microsoft somehow has the entirety of??

But I'm struck with how dumb, or just lacking in paranoia, this seemingly successful and rich hacker is. First of all he's using Windows. Excuse me? Second he used that device to log into personal stuff like Snapchat and Facebook. And he posted a picture of himself at a hotel that they tracked.
I'm no hacker, but if I were, I'd treat devices as disposable surgical gloves, and I wouldn't touch Windows.
