Is Bid Master safe?

Clean risk

Bid Master fetches shared Copart and IAAI buyer logins from its server and auto-fills them into the auction login pages.

On Copart and IAAI login pages the extension requests a shared buyer account from bidmaster.info, fills in the password and hides the login page behind a loader. It also sends lot visits, bids, watchlist items, won-vehicle and invoice table rows, plus your public IP address, to bidmaster.info. It deletes Copart and IAAI session cookies when it is logged out or a companion extension is removed.

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
