Lithuanian authorities are on high alert after a massive data leak involving more than 600,000 entries from national data registers, which is believed to have been executed by another country.
The Lithuanian general prosecutor’s office on Friday announced the leak was primarily from registers of real estate and legal entities accessed by using login credentials of institutions authorized to receive the data.
The head of the State Enterprise Centre of Registers, Adrijus Jusas, resigned Monday following the leak.
The authorities immediately implemented additional cybersecurity measures, including blocking the accounts of suspected data users and restricting access with a requirement to update credentials, the prosecutors said.
The prosecutor’s office said a foreign country is suspected of involvement, although authorities did not specified which nation.
