Is 1stream Client safe?

Low risk

1stream Client sends page hostnames to a bvoip endpoint when its webclient injection runs.

When a page response includes the 1stream webclient header, the extension marks the tab for injection after it finishes loading. The injected script posts the current page hostname as PbxFqdn to a bvoip region lookup endpoint before building the 1stream webclient UI.

Where it sends data

Destinations our analysis observed 1stream Client contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
