Amazon RSA 2048 M03 TLS Certificate

Yes. Amazon RSA 2048 M03 is a publicly trusted intermediate CA operated by Amazon Trust Services LLC and chained to Amazon Root CA 1. It is recognized by all mainstream browsers and operating system trust stores. The certificate itself is not a phishing indicator — the same intermediate signs millions of legitimate sites.

Amazon Trust Services LLC issues RSA domain-validated certificates automatically and at no cost (or very low cost), which is the exact workflow scammers need to put HTTPS on a throwaway domain. Domain validation only proves that the requester controls the domain name, not that the site behind it is trustworthy. phishunt lists the specific domains currently flagged below — those are the suspicious ones, not Amazon RSA 2048 M03 itself.

In a desktop browser, click the padlock in the address bar and open the certificate viewer. Confirm the issuer chain ends at Amazon Root CA 1, that the subject matches the domain you expect, and that the notAfter date has not passed. A valid Amazon RSA 2048 M03 certificate only proves TLS was negotiated correctly — always verify the domain name itself belongs to the service you intended to visit.

Amazon RSA 2048 M03 and its siblings (Amazon RSA 2048 M01, Amazon RSA 2048 M02) share the same operator (Amazon Trust Services LLC) and roll up to the same root (Amazon Root CA 1). CAs rotate multiple intermediates so that if one key ever has to be revoked, the damage is contained. As a user, you can treat all of them as the same trust anchor.
