This was a fun article to read. Yes Windows is more surveillance software than Android or Apple are - the article makes that case well at the end when talking about how tracking is more explicit and can be turned off on those.

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.

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.

>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?
