Is 红鸟-X/推特下载助手 safe?

Medium risk

红鸟-X/推特下载助手 sends the full URL of every page you visit, on all sites, to plug2025.bm-com.com.

The extension is a Twitter/X downloader, but its content script runs on every website. On each page load it reports the page URL and host, along with a stored user ID, session ID and paid-user status, to a remote server. This happens without user action and is not limited to x.com.

Shared hosts - 2 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.

Observation

Static analysis finding. This behaviour was identified by reading the shipped extension code and has not yet been reproduced in a live run. The trigger conditions and the exact data sent are read from the code, not from an observed capture.

What it can do

Permissions this extension asks for, as declared in version 1.2.2. Asking for a permission is not a finding on its own - it is what the extension can do if it chooses to.

Where it sends data

Destinations our analysis observed 红鸟-X/推特下载助手 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.
