Is アマストリーム会員様専用ツール 3 safe?
The extension sends Amazon Seller Central business report data and your login token to app5.jp.
This tool for Amastream members runs on Amazon, eBay, Rakuten, Yahoo Japan and related seller sites. When you use its business report feature, the content script reads the report and the background script posts it, with your auth token, user ID or email and seller ID, to the vendor's own backend at app5.jp.

What this publisher told the store about itself, and the other listings that told it the same thing.
Same store account
1 other listing published from this account, 10k+ users between them, none of them carrying a finding.
Shared hosts - 18 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.
