Attackers Hijack Domain Registries to Impersonate Trusted Websites

Attackers compromised national domain registries for Ghana (.gh), Sierra Leone (.sl), and American Samoa (.as) to obtain unauthorized HTTPS security certificates for Google domains. While Google's own systems were not breached, fraudulent certificates allow attackers to pose as legitimate websites over encrypted connections. This makes it easier for cybercriminals to intercept confidential data or run convincing phishing campaigns without triggering standard browser security warnings.

Who is affected

Any organization operating websites, regional branches, or web traffic using the .gh, .sl, or .as domain extensions.

How to mitigate it

  1. 1Audit your organization's domain inventory to identify any active web properties registered under the .gh, .sl, or .as extensions.
  2. 2Monitor certificate transparency logs for unauthorized security certificates issued to your company domains.
  3. 3Implement automated web filtering and endpoint protection to detect and block traffic to suspicious or hijacked domains.
  4. 4Remind staff to verify website addresses before entering corporate credentials, even on sites displaying an active HTTPS lock icon.
