Is gbfdrop safe?

Medium risk

gbfdrop stores the user's account password in plaintext browser extension storage.

When a user saves gbfdrop's options, the extension sends the entered username and password to its token endpoint and then keeps the same password in chrome.storage.local. The stored password is loaded back into the options page and reused later if token refresh fails, so it remains in extension storage after login.

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

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

Destinations our analysis observed gbfdrop 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.

  • api.gbfdrop.jp

    gbfdrop sends data to api.gbfdrop.jp. No other extension we have analysed sends data here.
