Lithuanian opposition launches parliamentary probe into mass data breach at Registry Centre

The Lithuanian parliamentary opposition will initiate a temporary investigative commission to examine a large-scale data breach at the state Registry Centre, opposition leaders announced on Wednesday.

Laurynas Kasčiūnas, chairman of the opposition Homeland Union–Lithuanian Christian Democrats, stated that the probe would seek to clarify all circumstances surrounding the leak, which he argued raised serious national security concerns beyond mere cybercrime. “We will launch a parliamentary investigation commission to uncover every detail related to the data theft from the Registry Centre,” Kasčiūnas told reporters in the Seimas.

Viktorija Čmilytė-Nielsen, leader of the Liberal Movement, added that the investigation must determine why affected individuals were not promptly notified about the compromise of their personal data. “We need to establish who made the decision to withhold this information from those impacted,” she said.

The breach, first reported by LRT, has prompted warnings from cybersecurity experts about potential targeted phishing attacks exploiting the stolen data. Authorities have also cautioned that ongoing system maintenance at the Registry Centre—including its e-health services—could face disruptions as a result of the incident.

The Registry Centre, a state institution managing Lithuania’s official registers, has not yet disclosed the full scope of the breach or the number of individuals affected.
