Mediaplex was listed by thegentlemen ransomware group on May 06, 2026, after internal files were exfiltrated in an attack whose exact timing remains unknown. Individuals who may have had data with Mediaplex should review their accounts and monitor for suspicious activity.
On May 6, 2026, the ransomware group thegentlemen listed Mediaplex on its leak site and claimed to have exfiltrated internal files from the company. The number of individuals whose information may be involved remains unknown, and no further details on the volume or contents of the material have been made public. For customers, suppliers, and employees connected to the Italian manufacturer, the incident raises questions about how any accessed records might be used.
The listing itself constitutes the primary public record of the event. Without independent confirmation of the data’s scope or subsequent distribution, the practical implications for affected people depend on what the files actually contain.
Breaking down the breach
The incident was reported on May 6, 2026. The only data type identified in the available record is internal files said to have been taken during a ransomware attack. The number of people affected is stated as unknown. No information has been released on the date of the intrusion, the method of access, or the quantity of material involved.
The group’s leak-site posting is presented as a claim rather than a verified account of events. No additional technical details or ransom demands have been disclosed in public sources.
Inside thegentlemen
Thegentlemen is a ransomware operator that maintains a leak site where it lists organizations it claims to have targeted. Such groups commonly encrypt systems and copy data before demanding payment, then publish samples or directories when negotiations fail. The current listing of Mediaplex follows this pattern of public attribution by the group itself.
No statements attributed to thegentlemen beyond the basic listing of Mediaplex have been recorded in the available facts.
Who is Mediaplex?
Mediaplex is a manufacturing company based in Casoria, near Naples, Italy. It specializes in CNC machining, laser cutting, and thermoforming of plexiglass and other plastics, producing precision components, decorative elements, and custom parts for clients primarily in the Campania region. The firm is described as serving both commercial and industrial customers requiring fabricated plastic materials.
Companies in this sector routinely maintain records related to orders, designs, client specifications, and internal operations. A breach at such a firm can therefore touch information belonging to both the business and its customers.
What was likely exposed
The only category named in the listing is internal files exfiltrated during the ransomware incident. The precise contents of those files have not been disclosed.
Manufacturing firms of this type commonly store customer contact details, order histories, technical drawings, supplier information, and employee records. Whether any of these categories appear in the exfiltrated material remains unconfirmed.
Why it matters
Internal files can include operational data whose exposure may affect business relationships or competitive information. If personal details are present, individuals could face risks such as targeted phishing or misuse of contact information. The absence of a confirmed count of affected people makes it difficult to assess the overall scale.
For the organization, the incident adds to the operational disruption already associated with ransomware events, including potential recovery costs and reputational effects within its client base.
Were you affected?
Individuals who have done business with Mediaplex or worked for the company have no confirmed way to determine involvement from public information alone. Practical steps include watching for unusual account activity and treating unsolicited messages with extra caution.
- Review bank and email accounts for unexpected activity.
- Enable or update multi-factor authentication on services tied to the company.
- Run a free exposure scan of your email address against known breach datasets.

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.
