During the overnight hours into April 4, 2025, Estonia's public sector institutions experienced ten cyberattacks, a number higher than usual but considered not extraordinary by Veikko Raasuke, chief of CERT Estonia at the Information System Authority (RIA). The attacks involved attempts to compromise systems, which CERT-EE successfully defended with no significant harm or disruption to public services. RIA confirmed the activity involved scanning attempts followed by unsuccessful hacking attempts, with some targeting website infrastructure and possible denial-of-service patterns. CERT-EE operates within a network of experts to detect and respond to such threats promptly, underscoring Estonia's resilient cybersecurity posture amidst persistent hostile cyber activities. The attacks were confirmed to be part of a broader trend of cyber intrusion attempts originating from foreign actors, likely linked to ongoing hybrid-warfare pressures in the Baltic region.
