> Microsoft records also indicate: (1) the user of the device assigned the GDID accessed multiple sites from Tzulo servers in May 2025, including the .168 server (the IP address used to create the ngrok account) on May 12, 2025; and (2) the user of the device assigned the GDID, on May 12, 2025 at 22:47 UTC, a little more than three hours after the ngrok account was created, the user visited “[Company F].com” from the .168 proxy server.
