What actually happens
You did this

You click the alerabat.com extension icon while visiting any website.

The click fires even when the site is unrelated to the extension's coupon/cashback purpose.

The extension did this

The extension immediately POSTs the hostname of your current tab to two Google Analytics endpoints.

Both GA v3 (UA-35417772-32) and GA v4 (G-8BK7QDVC14) requests are sent within the same debounce window (400 ms), each carrying a persistent device identifier.

Captured request
POSThttps://www.google-analytics.com/mp/collect?api_secret=<redacted>&measurement_id=G-8BK7QDVC14

Captured during dynamic analysis. client_id is a rnd_-prefixed UUID stored in extension local storage.
