Customs warns user data may be affected in cyber incident

Lithuanian Customs says personal data belonging to some users may have been affected in a cyber incident, LRT reported. The users had logged into its General User Management Portal on November 9 and 10.

The authority said on Wednesday that it was contacting people whose data may have been affected to explain the possible breach and recommend ways to reduce risks. It has also notified Lithuania’s State Data Protection Inspectorate and relevant European Union institutions.

Customs urged potentially affected users to be cautious about emails, text messages and calls asking for personal or financial information, and not to click suspicious links. It also advised checking website addresses carefully.

Access to the portal remains suspended for security reasons. The disruption mainly affects individuals and small businesses that use it to log in to other systems. Other customs information systems and services used by customs representatives and intermediaries are operating normally.

The investigation is ongoing. Customs said it is assessing the scale and possible impact of the incident, isolating connections to affected infrastructure, preserving data needed for the investigation and preparing to restore systems safely. External infrastructure and cybersecurity specialists are assisting.

On Tuesday evening, Lithuanian Customs reported signs of possible unauthorized activity in its information systems infrastructure.
