Estonia to quarantine emails sent from Russian .ru domain before they reach government officials

Estonia will begin additional security screening and quarantine for emails originating from the .ru top-level domain for government recipients starting August 31, citing a rise in malicious emails, phishing, malware, and disinformation linked to Russian servers since 2022; recipients will be notified if a message is isolated and advised to use extra precautions, while authorities encourage switching away from .ru providers as part of broader defenses against Kremlin-linked hybrid threats.
