Congoleum Listed by play Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Congoleum has been listed by the play ransomware group, with internal files reported to have been exfiltrated in the attack; the incident was disclosed on March 24, 2026, though the date of the intrusion itself has not been established. Anyone connected to Congoleum should check whether their information was exposed and take appropriate protective steps.
Inside the incident
The only confirmed public information is the appearance of Congoleum on the group’s leak site on the reported date. The entry asserts that files were taken from the organization’s systems. No independent verification of the claim, no timeline of the intrusion, and no description of how access was obtained have been disclosed. The number of people whose information may be involved remains unknown.
Who is play?
Play is a ransomware operation that has conducted multiple intrusions since at least 2022. Public reporting has linked the group to double-extortion tactics in which data is copied before encryption and later threatened with release. The group maintains a leak site where it lists victims and, in some cases, posts samples of claimed material. Its targets have included organizations in manufacturing, healthcare, and government sectors across several countries.
Who is Congoleum?
Congoleum operates in the United States as a manufacturer of flooring products. Companies in this sector maintain internal records that can include supplier contracts, production data, employee information, and financial documentation. A successful intrusion into such an environment can expose both business operations and personal data belonging to staff or business partners.
What data was at risk
The listing refers only to “internal files.” No further breakdown of file categories or data fields has been released. Organizations of this type commonly store employee records, customer or supplier details, and operational documents, but the precise contents of any exfiltrated material remain unconfirmed.
The real-world impact
Exposure of internal files can create risks of identity misuse if personal details are present, or of competitive or operational harm if proprietary information is involved. For the organization, the incident may lead to remediation costs, regulatory scrutiny, and loss of trust from customers and partners. Without a published list of affected individuals, the extent of personal impact cannot yet be measured.
Were you affected?
Individuals who have had contact with Congoleum can monitor official statements from the company for any future notifications. A practical first step is to review recent account activity and enable multi-factor authentication on any services that may share data with the organization. Readers can also run a free exposure scan of their email address against known breach datasets 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.
