Desk analysis

Attackers breached the registry operators behind three country-code top-level domains (.gh Ghana, .sl Sierra Leone, .as American Samoa), edited authoritative DNS records, and passed certificate-authority validation to obtain counterfeit TLS certificates for Google domains and other organizations. Google's disclosure puts the count at unauthorized certificates confirmed through Certificate Transparency logs; one report cites 12 forged certificates. The certificates were genuine, CA-signed documents issued to an attacker who could demonstrate DNS control rather than real ownership.

The technique bypasses the trust model rather than breaking encryption. Domain validation for HTTPS issuance typically relies on a TXT record challenge; control over authoritative DNS answers that challenge, so the attacker obtained valid certificates for domains they never controlled. Because ccTLDs issue domains to anyone regardless of geography, this exposed users well beyond the three countries. Successful abuse enables convincing brand impersonation with a padlock in the browser.

Google blocked the unauthorized certificates for its properties in Chrome via CRLSets and worked with the issuing CAs to revoke them. The company states its own systems were not compromised and that it has no reason to believe the CAs acted improperly. Ars Technica first reported the story on October 6; Google published its Chrome response on October 8.

What to watch: CT logs for additional certificates issued under .gh, .sl, or .as, whether the other affected organizations disclose, and whether the ccTLD operators publish incident detail. Registry-level compromise of this kind is rare and the response playbook for it, CA/Browser Forum side, is still unsettled.

    Hackers hijack Google domains after breaching ccTLD registries

    bleepingcomputer.com · 6d ago · October 7th, 2026

    Hackers obtained unauthorized HTTPS certificates for several Google domains and hijacked domains in the country-code top-level domains (ccTLDs) for Ghana, American Samoa, and Sierra Leone after compromising third-party operators and modifying authoritative DNS records. Google underlines that the attacks affected domains of other organizations in the .GH, .SL, and .AS ccTLDs but "did not involve a compromise of Google’s systems." By gaining access to the domain name system (DNS) records, a threat actor can request an HTTPS certificate from a Certificate Authority (CA) for a domain they don't own. CAs issue certificates after verifying ownership of the domain, a process that typically requires the requester to create a TXT record with a random value the CA provides. Modifying the authoritative DNS records allowed the threat actor to point .GH, .SL, and .AS domains to infrastructure they controlled while obtaining valid TLS certificates for those domains. This let the attacker impersonate legitimate brands and serve visitors arbitrary content from the affected domains. Google immediately blocked the unauthorized certificates for its properties in Chrome through CRLSets and worked with the issuing authorities to revoke them, extending protection to other clients. The company said that its systems were not affected by the incident in any way, and that it has no reason to believe that the issuing CAs acted improperly. After examining Certificate Transparency (CT) logs, the tech gia

    Attackers hijack country-code domains to impersonate Google and other services

    malware.news · 5d ago · October 8th, 2026

    These domain endings aren’t limited to sites serving those countries, so the risk can extend to users elsewhere. This wasn’t a break in encryption, and Google’s systems weren’t compromised. Instead, attackers manipulated the internet’s addressing infrastructure so they could pass the checks required to obtain certificates for domains they didn’t legitimately control. The Domain Name System (DNS) helps direct internet traffic to the right destination. Control over DNS can also provide a way to demonstrate apparent control of a domain when requesting an HTTPS certificate. An HTTPS certificate helps a browser authenticat e the server it is connecting to . A trusted certificate authority issues the certificate after checking that the applicant controls the relevant domain. The authority can then issue a genuine, signed certificate to someone who has hijacked the domain’s infrastructure. Combined with the ability to redirect a victim’s traffic to an attacker-controlled server, that could enable cybercriminals to create a convincing impersonation of the real service.
