Is ASUS Download Master Chrome Extension safe?

Medium risk

ASUS Download Master Chrome Extension sends router login credentials to its default HTTP router endpoint.

When checking settings or sending downloads from the context menu, the extension posts the configured username and password as form fields to http://router.asus.com:8081/check.asp by default. The values are base64-encoded but travel over HTTP unless the user changes the router URL to HTTPS.
