Novosit Listed by play Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to dominate the cyber-threat landscape in 2025, routinely combining data theft with encryption and public leak-site postings to pressure organisations into paying. Listings appear almost daily, often with limited independent verification, leaving affected people and partners to piece together the real impact from sparse public claims. Against that backdrop, the appearance of Novosit on a ransomware group’s site is one more data point in a pattern that has become routine yet still consequential for those whose information may have been taken.

On 5 May 2025, the ransomware group known as play listed Novosit, an organisation based in the Dominican Republic, claiming to have exfiltrated internal files during a ransomware attack. The number of people affected remains unknown, and public detail beyond the group’s claim is limited. The incident matters because any confirmed exposure of internal files can create lasting risks for employees, customers or partners whose data may have been among the material taken.

Breaking down the breach

According to the available record, Novosit was listed by the play ransomware group on 5 May 2025. The group asserts that internal files were exfiltrated as part of a ransomware attack. No independent confirmation of the intrusion method, the precise date of access, the volume of data taken, or the number of individuals affected has been made public. The only geographic detail supplied is that the organisation is associated with the Dominican Republic. Beyond the claim of internal-file exfiltration, the record does not name specific file categories, systems compromised, or any ransom demand. In short, the public picture rests almost entirely on the group’s leak-site listing; everything else remains undisclosed.

Who is play?

Play is a well-documented ransomware operation that has been active for several years. Like many contemporary groups, it typically employs a double-extortion model: data is stolen before systems are encrypted, and victims are threatened with public release of the material if a ransom is not paid. The group maintains a dark-web leak site on which it posts victim names, sometimes accompanied by sample files or countdown timers. Play has previously targeted organisations across multiple sectors and regions, often focusing on mid-sized entities whose operational disruption can be leveraged for payment. Its listings are claims, not Reported Facts; security researchers treat them as assertions that require independent corroboration. Nothing in the public record of this particular incident goes beyond the group’s assertion that Novosit’s internal files were taken.

About Novosit

Public information about Novosit is sparse. The organisation is identified as operating in the Dominican Republic. Companies of this type commonly maintain internal business records, employee information, operational documents and, depending on their exact line of work, customer or partner data. Because the precise nature of Novosit’s activities is not detailed in the breach record, it is not possible to state with certainty what systems or repositories would have been most attractive to an attacker. A ransomware incident involving any organisation that holds internal files is consequential simply because those files often contain personal or commercially sensitive material that, once outside the organisation’s control, can be misused or further circulated.

What data was at risk

The only data type named in the public record is “internal files” said to have been exfiltrated. No further breakdown—such as employee records, financial documents, customer databases or intellectual property—has been disclosed. Organisations of comparable size and location typically hold a range of internal material: personnel files, contracts, correspondence, system configurations and operational data. Whether any of those categories were among the files claimed by play remains unconfirmed. The number of people whose information may have been included is listed as unknown. Readers should therefore treat the exact contents of the alleged exfiltration as unverified.

Why it matters

When internal files leave an organisation’s control, the practical risks are concrete even if the precise contents stay unknown. Individuals whose personal details appear in those files may face phishing, identity fraud or unwanted contact. Business partners or clients mentioned in the material could see confidential commercial information exposed. For the organisation itself, the incident can bring regulatory scrutiny, contractual obligations to notify affected parties, and the operational cost of investigation and remediation. Because the scale remains undisclosed, the full extent of these risks cannot yet be quantified; the mere claim of exfiltration is enough to warrant caution and monitoring by anyone connected to Novosit.

Were you affected?

If you have a past or present relationship with Novosit—as an employee, customer, supplier or partner—treat the possibility of exposure seriously until more information emerges. Monitor financial and email accounts for unusual activity, enable multi-factor authentication wherever available, and be alert to unexpected messages that reference the organisation or request personal details. Consider placing fraud alerts with credit bureaus if you believe sensitive identifiers may have been involved. You can also run a free exposure scan of your email address to check whether it has already appeared in known breach data sets. Official notifications, if any are issued by Novosit or local authorities, will provide the most reliable guidance on next steps.
