Afezo Listed by thegentlemen Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Afezo was listed by thegentlemen ransomware group on March 01, 2026, with internal files reported as exfiltrated. Individuals who may have had dealings with Afezo should check for any direct notifications and take appropriate protective steps.
What happened
The only confirmed information is the listing itself. Thegentlemen posted Afezo on its site on the reported date and asserted that files had been removed from the company’s systems. No independent confirmation of the claim, the volume of data, or the method of access has been released. The number of individuals potentially affected is listed as unknown.
Who is thegentlemen?
Thegentlemen is a ransomware operation that has appeared on leak sites in recent years. Groups of this type typically combine encryption of systems with the threat of publishing stolen files to pressure victims. Their listings are presented by the group as evidence of successful intrusions, though the accuracy of any individual claim is not verified by outside parties unless the victim or investigators confirm it.
Afezo and its sector
Afezo B.V. is a family-owned Dutch company based in the Amsterdam region that carries out urban sewer work, wastewater management, road construction, and drinking-water network projects. Organizations in this sector routinely handle operational records, project documentation, client correspondence, and technical specifications related to public infrastructure.
What data was at risk
The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of specific file types or data categories has been published. Companies of this kind commonly store contracts, engineering drawings, maintenance logs, and communications with municipal clients, but the exact material taken in this case remains unconfirmed beyond the group’s general description.
Why it matters
Infrastructure contractors hold records that can include details of public works and relationships with local authorities. Exposure of such material can create operational disruption for the company and may indirectly affect planning or procurement processes for the municipalities it serves. For any individuals whose personal or contact information appears in the files, the main concern is the potential for targeted follow-on activity such as phishing or misuse of credentials.
If your data was in this claimed breach
Monitor accounts associated with any project or contract work involving Afezo and enable multi-factor authentication where available. Watch for unusual messages that reference the company or its projects. Individuals can also run a free exposure scan of their email address against known breach data to see whether their information has appeared in previously published sets.

Publicly posted by thegentlemen — 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.
