Google Domains Hit by .gh .sl .as ccTLD DNS Hijacks Enabling Unauthorized Certificates

ccTLD DNS hijacks of .gh .sl and .as produced unauthorized certificates for Google domains. CT logs and cached DCV state enabled the attacks; CAA records are the remaining control. The incident reveals repeated registry weaknesses not addressed by current issuance practices.

Domain owners should immediately publish CAA records limiting issuance to specific accounts and validation methods. CAs and browsers will continue to watch CT logs for similar anomalies. Expect additional disclosures from other affected organizations as log scraping continues over the next two weeks.

⚡ Prediction

Google CT team: At least five additional organizations will publicly disclose rogue certificates from the same hijacks within 21 days.
