manuaco.pt Listed by lockbit5 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
manuaco.pt was listed by the lockbit5 ransomware group on December 25, 2025, after internal files were exfiltrated. Check any accounts or services you hold with the organization and follow its guidance if you are affected.
Inside the incident
The only confirmed detail is the appearance of manuaco.pt on the group’s listing on the reported date. The group claims internal files were taken. No independent confirmation of the exfiltration, the volume of data, or the timeline of the operation has been made public. The number of people potentially impacted is listed as unknown.
The group behind it: lockbit5
LockBit operates as a ransomware-as-a-service model in which affiliates deploy the encryption tools and share proceeds with the operators. Public reporting has documented the group’s repeated use of data theft alongside encryption to pressure victims. The group maintains a leak site where it lists organizations it claims to have targeted. The listing of manuaco.pt constitutes the group’s assertion; no separate verification of the claim has been provided by the organization or law-enforcement sources.
About manuaco.pt
Manuaco.pt is a Portuguese company that began operations in 2006 with José Fernando as its sole managing partner. Entities of this type commonly maintain records related to contracts, suppliers, employees, and clients. A compromise involving internal files can therefore expose operational and personal information held in the ordinary course of business.
The information in question
The only data category named in the listing is “internal files exfiltrated in ransomware attack.” No further breakdown of file types or data fields has been disclosed. Organizations in this sector routinely store employee records, customer details, financial documents, and correspondence; whether any of these categories were among the files cannot be confirmed from available information.
What's at stake
Exfiltrated internal files can be used for fraud, targeted phishing, or resale on criminal markets if they contain personal or financial details. For the organization, the incident may result in regulatory scrutiny under Portuguese and EU data-protection rules and in costs associated with investigation and remediation. Individuals whose information appears in the files face the standard risks of identity misuse or account compromise.
Were you affected?
Individuals who have had dealings with manuaco.pt should contact the company directly for information on any exposure. Monitoring bank and email accounts for unusual activity remains a practical first step.

Publicly posted by lockbit5 — unverified claim, pending independent verification
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.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
