Quezon Power was listed by the ransomware group devman on December 10, 2025. The listing states that internal files were exfiltrated during a ransomware attack, with references to employee data, HR information, projects, power-plant work logs, and SCADA SRC. The number of individuals affected has not been disclosed.
Inside the incident
Public information about the event remains limited to the group’s listing. No Reported Details have been released on when the intrusion occurred, how access was obtained, the volume of data involved, or whether encryption was deployed alongside the exfiltration. The organisation has not issued a statement confirming or denying the claims at the time of reporting.
The group behind it: devman
Devman is a ransomware operator that maintains a leak site to list organisations from which it claims to have taken data. Like other groups in this category, it typically combines encryption of systems with the threat of publishing stolen files. Its listings are presented by the group itself and are not independently verified in every case. Prior activity attributed to the group has focused on entities in multiple countries and sectors, with similar claims of data removal.
Quezon Power and its sector
Quezon Power operates in the electricity generation sector. Organisations of this type maintain records related to plant operations, maintenance schedules, employee administration, and industrial control systems. A breach involving such material can intersect with both personal information and details of critical infrastructure processes.
The information in question
The listing names employee data, HR information, projects, work logs of the power plants, and SCADA SRC as among the files taken. The precise contents, formats, or completeness of any dataset have not been independently confirmed. Organisations in this sector routinely hold personnel records and operational documentation, but the exact scope in this instance remains unverified.
What's at stake
Individuals whose employee or HR data appears in the material may face risks of identity misuse or targeted fraud. For the organisation, exposure of operational logs and control-system references could complicate incident response and regulatory scrutiny. No confirmed evidence of subsequent misuse has been reported to date.
What to do if you're exposed
Anyone who believes their information may be involved should monitor bank and benefits accounts for unusual activity, enable multi-factor authentication on work and personal services, and consider placing fraud alerts with credit agencies where available. Readers can run a free exposure scan of their email address against known breach data to check for prior appearances in published records.

Publicly posted by devman — 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.
