TrustAsia TLS RSA CA

TrustAsia TLS RSA CA is a publicly trusted intermediate certificate authority operated by TrustAsia Technologies, Inc. and chained to DigiCert Global Root CA. 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; TrustAsia TLS RSA CA as a CA is fine.

TrustAsia Technologies, 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 TrustAsia TLS RSA CA 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 TrustAsia TLS RSA CA certificate only proves TLS was negotiated correctly — always verify the domain name itself belongs to the service you intended to visit.

TrustAsia TLS RSA CA and its siblings (TrustAsia RSA DV TLS CA G2) share the same operator (TrustAsia Technologies, 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.
