Is AsinSeed - Amazon Product & Keyword Tools safe?

Medium risk

AsinSeed sends an MD5-derived password value in the sign-in URL query string to www.asinseed.com.

When a user signs in from the Amazon content UI, the extension hashes the entered password with MD5 and sends the email and hash as URL query parameters to its sign-in endpoint. The hash is unsalted and reusable, so the credential-derived value can be replayed if the request URL is captured.

Where it sends data

Destinations our analysis observed AsinSeed 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.
