This page pretends to be: a Microsoft "Sign in" popup window.

The trick: this whole "browser window" is FAKE — the title bar, the traffic-light buttons and the address bar are just pictures drawn inside the webpage to make you trust the https://login.microsoftonline.com address. The real page is somewhere else.

✅ With VIYUH BDR ON you SHOULD see: a full-page BLOCK warning (Browser-in-the-Browser, high severity).

👉 Mark PASS if you saw the block, FAIL if the login just sat there.
