RapidSSL TLS RSA CA G1 TLS Certificate

RapidSSL TLS RSA CA G1 is a publicly trusted intermediate certificate authority operated by DigiCert (RapidSSL brand) and chained to DigiCert Global Root G2. It is recognized by all mainstream browsers and operating system trust stores, so the certificate itself is not a phishing indicator - the same intermediate signs millions of legitimate sites. phishunt only flags the specific domains listed below as suspicious; RapidSSL TLS RSA CA G1 as a CA is fine.

DigiCert (RapidSSL brand) 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 RapidSSL TLS RSA CA G1 itself.

In a desktop browser, click the padlock in the address bar and open the certificate viewer. Confirm the issuer chain ends at DigiCert Global Root G2, that the subject matches the domain you expect, and that the notAfter date has not passed. A valid RapidSSL TLS RSA CA G1 certificate only proves TLS was negotiated correctly — always verify the domain name itself belongs to the service you intended to visit.

RapidSSL TLS RSA CA G1 and its siblings (Thawte TLS RSA CA G1, GeoTrust TLS RSA CA G1, Encryption Everywhere DV TLS CA - G1, RapidSSL TLS DV RSA Mixed SHA256 2020 CA-1) share the same operator (DigiCert (RapidSSL brand)) and roll up to the same root (DigiCert Global Root G2). 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.
