Estonia's state institutions suffered the largest DDoS cyberattack on March 9-10, 2024, with limited impact due to effective mitigation by RIA.
On the weekend of March 9-10, 2024, Estonia's state institutions experienced the largest distributed denial of service (DDoS) attacks recorded in the country to date. The attacks targeted multiple government websites and services. Despite the scale, the impact was limited due to proactive mitigation efforts and cybersecurity measures by Estonia's Information System Authority (RIA). RIA confirmed that the attacks originated from abroad, primarily Russia, as part of continuous hostile cyber activity against Estonia. Several state institutions faced intermittent service disruptions, but critical services remained operational. Authorities continue to monitor cyber threats and enhance resilience.
Confidence: High
The event is classified as an aggressor event because it describes a large-scale hostile Russian-origin DDoS cyberattack against Estonian state institutions. It is not classified as a defense preparation event since the article focuses on the attack and mitigation after the event rather than proactive defense preparations.
