What happened
Grupo Tomza appeared on the qilin ransomware group's leak site on February 21, 2026.

No information has been released about when the intrusion occurred, how many files were taken, or whether any systems were encrypted. The number of people affected is also undisclosed.
Inside qilin
Qilin is a ransomware group that maintains a public leak site and follows a double-extortion model. In this approach, operators first exfiltrate data and then threaten its publication if a ransom demand is not met. The group has previously listed organizations from multiple sectors on the same platform. Its listings function as a claim of possession rather than an independently verified event.
About Grupo Tomza
Grupo Tomza is a private organization operating in the commercial sector. Entities of this type routinely maintain records related to operations, contracts, personnel, and internal communications. A breach that exposes such material can affect business continuity and the privacy of individuals whose details appear in those records.
The information in question
The only description provided is that internal files were allegedly exfiltrated. The precise categories of data contained in those files have not been disclosed. Organizations in this sector commonly store employee records, financial documents, customer information, and operational details, but it is not confirmed whether any of these specific types were taken in this case.
Why it matters
When internal files are removed from an organization, the main risks involve potential misuse of any personal or operational data they contain. Individuals may face increased chances of targeted scams or identity-related fraud if their details are later circulated. For the organization, the exposure can complicate regulatory compliance and require additional resources to assess and contain the impact.
What to do if you're exposed
Individuals who believe their information may be involved should monitor their financial and email accounts for unusual activity and enable multi-factor authentication where available. Changing passwords for any reused credentials is a standard first step. Readers can also run a free exposure scan of their email address against known breach data to check for prior appearances of their information.

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.
