Is XlsWork safe?

Question

Is XlsWork safe?

Accepted Answer

XlsWork is high risk. Each time you navigate to a website, this extension reads the URL and sends it to stream.redcoolmedia.net alongside a 10-character ID generated the first time the extension runs. That ID never changes and never resets — it ties every URL you visit across all browser sessions into a single browsing profile on the developer's server. Traffic analysis confirms the same ID appeared in all captured requests during testing. Every time you open, switch to, or reload a browser tab, this extension reads the full URL and transmits it to stream.redcoolmedia.net. The transmission is automatic, covers all HTTP and HTTPS websites, and occurs on every navigation — not just file downloads or specific page types. Dynamic analysis confirmed a real GET request carrying the hex-encoded URL and a stable tracking ID was sent to the developer's server when a tab was activated.
