• How does Microsoft know which GDID is accessing which websites?

    The document adds that Microsoft records also showed the GDID accessing “multiple sites” from servers at Tzulo, a web hosting provider, to help pull off the hack.

    The GDID is one thing, but how is the connection to activities made? Is the GDID sent while making requests to a server (in this case Tzulo), which records it? But then it wouldn’t be microsoft records showing that. But if it isn‘t, how do you know which GDID visits a website? If Microsoft is collecting which website is visited on device and sending it off to their servers then the GDID is the smallest thing to worry about.

  • Poor kid. Seems he was just starting out and didn’t get into the weeds of OpSec.

    He used a personal laptop with his personal information stored on it tied to an identifier. Not great OpSec. A hardware ID spoofer or a partitioned disk with different OS would’ve made wonders.

  • Maybe I’m missing something here but how is that not a logical conclusion for any service where you have a unique identifier? If it can get your IP it can get a general idea (CGNAT/VPN can screw with it a bit), if it’s allowed network access it can get nearby APs, which are pretty well mapped at this point, and if you allow it GPS, well that’s a no brainer.
