DigiCert TLS RSA SHA256 2020 CA1 TLS Certificate

Yes. DigiCert TLS RSA SHA256 2020 CA1 is a publicly trusted intermediate CA operated by DigiCert, Inc. and chained to DigiCert Global Root CA. 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.

DigiCert, Inc. 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 DigiCert TLS RSA SHA256 2020 CA1 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 CA, that the subject matches the domain you expect, and that the notAfter date has not passed. A valid DigiCert TLS RSA SHA256 2020 CA1 certificate only proves TLS was negotiated correctly — always verify the domain name itself belongs to the service you intended to visit.

DigiCert TLS RSA SHA256 2020 CA1 and its siblings (DigiCert Global G2 TLS RSA SHA256 2020 CA1, DigiCert TLS Hybrid ECC SHA384 2020 CA1) share the same operator (DigiCert, Inc.) and roll up to the same root (DigiCert Global Root CA). 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.
