Google Trust Services: Mis-issued certificates for citi.com subdomain due to lack of CAA record checking

RESOLVED INVALID Google Trust Services LLC
AI Summary

Google Trust Services LLC issued two certificates for the subdomain bt-preview.citicards.citi.com despite an existing CAA record that should have prevented this. The certificates were revoked at the request of Citi. An investigation revealed that the CAA record was in place at the time of issuance, suggesting a potential misconfiguration by someone with control over the DNS settings. Google Trust Services concluded that their issuance process was compliant with the relevant standards and closed the case as invalid.
