Is UTurbo safe?

Medium risk

UTurbo sends the active tab URL and browser user agent to carbonvpn.tech when its popup opens.

When the UTurbo popup opens, it reads the current active tab URL and browser user agent. It sends those values, along with extension status and its Carbon VPN cookie fields, to carbonvpn.tech over a POST request.

What this publisher told the store about itself, and the other listings that told it the same thing.

Shared hosts - 1 hostname

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.

Where it sends data
