Google Trust Services: Forbidden Domain Validation Method 3.2.2.4.10
Google Trust Services (GTS) was reported for using a forbidden domain validation method as outlined in their Certificate Policy Statement (CPS). The method in question, which was still referenced in their CPS, was retired under the Baseline Requirements. GTS acknowledged the issue and initiated an incident report, confirming that they had not used the deprecated method since September 2020. They subsequently updated their CPS to reflect the correct validation method and began revocation of affected certificates. The incident involved over a million certificates, and GTS has committed to monitoring and improving their compliance processes.
- Mozilla Bug 1706967 is filed.
- GTS CPS is updated to remove the forbidden validation method.
- Re-issuance and revocation of affected certificates begins.
- GTS shares the incident report.
