smtuc.pt Listed by lockbit2 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The smtuc.pt Listed by lockbit2 Ransomware Group (reported May 1, 2022) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
What happened
The incident came to public notice when smtuc.pt appeared on the LockBit2 leak site on May 1, 2022. The group claims to have exfiltrated internal files in a ransomware attack. No further details on the timing of the intrusion, the method of initial access, the volume of data taken, or any ransom demand have been made public. The number of individuals potentially affected is listed as unknown.
Who is lockbit2?
LockBit2 refers to a ransomware-as-a-service operation that has been publicly documented since at least 2019. The group develops and distributes ransomware tools to affiliate actors who carry out intrusions, encryption, and data theft. Its operators maintain a leak site where they list victims that have not paid demanded ransoms and publish samples of claimed stolen material. The group has been linked in public reporting to numerous incidents across multiple countries and sectors, though responsibility for any specific breach is determined by law-enforcement attribution rather than the listing itself.
About smtuc.pt
Smtuc.pt is the online presence of Serviços Municipalizados de Transportes Urbanos de Coimbra, the municipal body responsible for urban public transport in Coimbra, Portugal. Organizations of this type manage bus fleets, ticketing systems, passenger accounts, employee records, and operational infrastructure. They routinely process personal data such as names, addresses, payment details, and travel patterns, as well as internal administrative and technical documents.
What was likely exposed
The only information released states that internal files were exfiltrated. The exact categories of data contained in those files have not been disclosed. Public-transport operators commonly hold customer identifiers, financial transaction records, employee information, and network credentials, but it is not confirmed whether any of these data types were present in the material claimed by the group.
Why it matters
Exposure of internal files from a transport operator can create downstream risks for individuals whose records appear in those files, including potential misuse of personal or financial details. For the organization, the incident may affect operational continuity and require remediation of access controls. Because the scale and sensitivity of the data remain unconfirmed, the practical consequences for any specific person cannot yet be quantified from available information.
If your data was in this claimed breach
Monitor bank and government-service accounts for unusual activity and consider placing fraud alerts with credit agencies. Review and update passwords for any transport-related accounts, and enable multi-factor authentication where available. Readers can also run a free exposure scan of their email address against known breach datasets to check for appearances in previously published records.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
