Lithuanian authorities are on high alert following a massive data leak involving more than 600,000 entries from national registers, which is believed to have been orchestrated by a foreign country. The Lithuanian general prosecutor's office announced on Friday that the breach primarily targeted registers of real estate and legal entities, accessed using login credentials from authorized institutions. Adrijus Jusas, the head of the State Enterprise Centre of Registers, resigned on Monday in the wake of the incident.
Cybersecurity Measures and Suspicions
The authorities have implemented additional cybersecurity measures, including blocking accounts of suspected data users and restricting access with a requirement to update credentials, according to prosecutors. While a foreign country is suspected of involvement, officials have not specified which nation. Given Lithuania's population of 2.9 million and its status as a key target of Russia's hybrid war against Europe—encompassing sabotage, arson, vandalism, and influence operations—the country remains particularly vigilant.
Political Reactions and Potential Risks
Opposition politician Laurynas Kasčiūnas wrote on social media Sunday that the data theft is suspected to be a Russian intelligence operation, though he provided no evidence for the claim. He warned that addresses of intelligence officers, military personnel, diplomats, or politicians may have been accessed, potentially enabling perpetrators to spy on or exert pressure on these individuals.
