Is Steamlvlup Card Factory safe?
Steamlvlup Card Factory writes server-returned bytes onto the user's authenticated Steam WebSocket to auto-play games and farm cards.
To automate Steam card farming, the extension relays your Steam session id, SteamID, and an auth token to extension.steamlvlup.com, which responds with raw byte payloads. Those bytes are written straight onto the page's live, already-authenticated Steam Client Messaging WebSocket with no check on the message type or contents beyond a bare success flag, so the remote server effectively controls what gets sent over your real Steam session. The extension also relays Steam client events (games played, item announcements) back to the same server.

What this publisher told the store about itself, and the other listings that told it the same thing.
Shared hosts - 3 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.

What it can do

Where it sends data
Destinations our analysis observed SCF 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.
