Polyrack Listed by thegentlemen Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Polyrack was listed by thegentlemen ransomware group on May 18, 2026, after internal files were exfiltrated in a ransomware attack. An undisclosed number of people may have been affected; check whether your data was involved and take protective steps.
Inside the incident
The only confirmed information is the listing itself and the assertion that internal files were taken. No date of the intrusion, volume of data, or method of access has been disclosed. The company has not issued a public statement on the matter, and independent verification of the files or their contents is not available from public sources.
The group behind it: thegentlemen
Thegentlemen is a ransomware operator that maintains a leak site where it lists organizations it claims to have compromised. Such groups typically gain initial access through phishing, remote-desktop vulnerabilities, or supply-chain weaknesses, then deploy encryption while copying files for later leverage. The listing of Polyrack constitutes the group’s claim; no independent confirmation of the breach or data authenticity has been reported.
Polyrack and its sector
Polyrack Tech-Group is a family-owned German firm established in 1979. It designs and manufactures electronic enclosures, subracks, backplanes, and rugged mechanical components used in aerospace, medical technology, telecommunications, and transportation. The company employs more than 500 people across multiple sites and supplies precision-engineered parts that often enter regulated supply chains.
What was likely exposed
The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of file types, customer records, or technical data has been published. Organizations in this sector commonly hold engineering drawings, supplier contracts, quality-control records, and employee or customer contact information, yet the precise contents of any exfiltrated material remain unconfirmed.
Why it matters
Even without confirmed personal-data categories, engineering files from firms serving aerospace and medical markets can contain specifications subject to export controls or safety standards. Exposure of such material may create competitive or regulatory concerns for the company and its clients. Individuals whose contact details appear in internal records face the ordinary risks of phishing or impersonation that follow any corporate data incident.
Were you affected?
Anyone who has corresponded with Polyrack or worked with the firm may wish to monitor their email accounts for unusual activity. Running a free exposure scan of an email address against known breach repositories provides one initial check. Organizations should also review any contractual obligations regarding notification if they believe their own data may be involved.

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.
