Data of hundreds of thousands of citizens leaked in Lithuania as a result of a cyberattack.

Omissions

• The precise number of affected citizens varies across sources: Cybernews reports around 540,000 people affected, while Euronews and LRT cite over 600,000 records. This variation may reflect different counting methods (individuals vs. registry entries).
• The MEP did not name the specific institution (State Enterprise Centre of Registers) or the date (late May 2026), making the claim broadly accurate but unspecific.
• Some reports describe the method as abuse of legitimately issued login credentials rather than a traditional external hack, though authorities framed it within the broader context of foreign cyber attacks.
