What is Entrust Certification Authority - L1K?
Entrust Certification Authority - L1K is a publicly trusted intermediate certificate authority operated by Entrust, Inc. and chained to Entrust Root Certification Authority - 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; Entrust Certification Authority - L1K as a CA is fine.
Is Entrust Certification Authority - L1K a legitimate certificate authority?
Yes. Entrust Certification Authority - L1K is a publicly trusted intermediate CA operated by Entrust, Inc., included in the Microsoft, Apple, Google and Mozilla root trust stores. Every mainstream browser automatically accepts certificates it signs. The intermediate itself is not a phishing signal — what matters is the specific domain. phishunt flags only the suspicious domains listed below; Entrust Certification Authority - L1K keeps signing millions of legitimate sites.
Who runs the Entrust Certification Authority - L1K certificate authority?
Entrust Certification Authority - L1K is operated by Entrust, Inc.. It is a RSA intermediate that chains up to the Entrust Root Certification Authority - G2 root, which Entrust, Inc. also owns. Anyone can look up the chain in the public Certificate Transparency logs; the same operator publishes a Certificate Policy / Certification Practice Statement (CP/CPS) describing how issuance and revocation work.
What does Entrust Certification Authority - L1K mean when my browser shows it as the issuer?
When a browser shows Entrust Certification Authority - L1K as the certificate issuer for a site, it means TLS was validated through Entrust, Inc.'s RSA chain ending at Entrust Root Certification Authority - G2. That is normal for tens of millions of legitimate sites that use Entrust, Inc.'s automated DV TLS. The certificate proves the connection is encrypted and that the certificate matches the hostname — it does not prove the site behind it is trustworthy. Always verify the domain name itself.
Why does Entrust Certification Authority - L1K show up on phishing sites?
Entrust, 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 Entrust Certification Authority - L1K itself.
How do I verify a certificate issued by Entrust Certification Authority - L1K?
In a desktop browser, click the padlock in the address bar and open the certificate viewer. Confirm the issuer chain ends at Entrust Root Certification Authority - G2, that the subject matches the domain you expect, and that the notAfter date has not passed. A valid Entrust Certification Authority - L1K certificate only proves TLS was negotiated correctly — always verify the domain name itself belongs to the service you intended to visit.
What is the difference between Entrust Certification Authority - L1K and Entrust Certification Authority - L1M?
Entrust Certification Authority - L1K and its siblings (Entrust Certification Authority - L1M) share the same operator (Entrust, Inc.) and roll up to the same root (Entrust Root Certification Authority - 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.
