Is GeoSpoof: Spoof Geolocation & Timezone safe?

Low risk

GeoSpoof lets webpages disable its in-page WebRTC protection before probing IP candidates.

GeoSpoof injects a page-level script that listens for a settings event, but webpages can send the same event with settings that turn WebRTC protection off. After that, the extension's WebRTC wrappers can leave peer connections and stats unsanitized in that page, allowing IP candidates to be probed.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Shared hosts - 4 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
