Is Magnet拡張機能 safe?

Low risk

Magnet extension sends Yahoo Store Creator page HTML to ec-magnet.com during error logging.

When certain StoreDesignManager pages enter the extension's error flow, the extension logs the full page HTML and sends it with the page URL and shop key to ec-magnet.com. That page HTML can include visible DOM content and any form values present on the Yahoo Store Creator page at the time of the error.

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

Destinations our analysis observed Magnet拡張機能 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.

  • ec-magnet.com

    Magnet拡張機能 sends data to ec-magnet.com. No other extension we have analysed sends data here.
