Is Amazon Vine Ultraviner safe?

Medium risk

Amazon Vine Ultraviner downloads code from ultraviner.com and registers it to run on Amazon Vine pages.

The extension fetches a user script from ultraviner.com, stores the returned text locally, fetches any dependency scripts named by that downloaded script, and registers the combined code to run on Amazon Vine pages. This means code outside the packaged extension can be supplied by ultraviner.com and by dependency URLs named in the downloaded script.

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.
