Operator-name view of Google's free public ACME endpoint (pki.goog). When the cert's Organization field shows only the operator without an intermediate CN, the issuing CA is one of WE1/WE2 (ECDSA) or WR1/WR2/WR4/GTS CA 1C3/GTS CA 1D4 (RSA).
Public ACME issuance opened in 2022; volume has grown rapidly. Same abuse profile as the underlying intermediates.
Frequently asked questions
What is Google Trust Services?
Google Trust Services is a publicly trusted intermediate certificate authority operated by Google Trust Services LLC and chained to GTS Root R1, GTS Root R4. 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; Google Trust Services as a CA is fine.
Why does Google Trust Services show up on phishing sites?
Google Trust Services LLC issues RSA & ECDSA 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 Google Trust Services itself.
How do I verify a certificate issued by Google Trust Services?
In a desktop browser, click the padlock in the address bar and open the certificate viewer. Confirm the issuer chain ends at GTS Root R1, GTS Root R4, that the subject matches the domain you expect, and that the notAfter date has not passed. A valid Google Trust Services 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 Google Trust Services and WE1?
Google Trust Services and its siblings (WE1, WE2, WR1, WR2) share the same operator (Google Trust Services LLC) and roll up to the same root (GTS Root R1, GTS Root R4). 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.
It is strongly recommended to use them for Threat Hunting or add them to a Watchlist.
