Chemical Computing Group Listed by play Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Chemical Computing Group has been listed by the play ransomware group, with internal files reported exfiltrated in an attack disclosed on February 22, 2026. An undisclosed number of individuals may have been affected; anyone connected to the organisation should check for notifications and take recommended protective steps.
What happened
The incident came to public attention when the Play group added Chemical Computing Group to its leak site. The only detail provided in the listing is that internal files were taken. No confirmation has been issued by the organisation, and no timeline for the intrusion, method of initial access, or extent of encryption has been disclosed.
Who is play?
Play is a ransomware operation that has appeared in incident reports since 2023. Public records show the group typically gains access through common initial vectors such as compromised remote-access services, then moves laterally, deploys encryption, and exfiltrates data before demanding payment. It maintains a leak site where it lists organisations and posts samples of claimed stolen material when negotiations fail or are refused.
Chemical Computing Group and its sector
Chemical Computing Group develops molecular modelling and cheminformatics software used by pharmaceutical, biotechnology and academic research teams. Organisations in this sector routinely store proprietary algorithms, research datasets, licensing information and customer records. A successful intrusion therefore touches both commercial intellectual property and data belonging to external research partners.
The information in question
The listing refers only to “internal files.” No inventory of specific file types or data categories has been published. Companies of this kind commonly hold source code, simulation results, employee records and contractual documents; however, the precise contents taken in this case remain unconfirmed.
What's at stake
Exfiltrated internal files can expose research methods and client information that competitors or other actors may seek to exploit. Individuals whose personal details appear in those files face the usual risks of identity misuse. For the organisation, the incident adds operational disruption, potential regulatory scrutiny under Canadian privacy law, and the possibility of further contact from the actors holding the data.
What to do if you're exposed
Individuals who believe their information may be involved should monitor financial and email accounts for unusual activity and enable multi-factor authentication on any services that still permit it. Organisations can review their own logging for signs of prior unauthorised access. Readers may also run a free exposure scan of their email address against known breach data to determine whether their details have appeared in previously published datasets.

Publicly posted by play — 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.
