Onyx Graphics Listed by coinbasecartel Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Onyx Graphics has been listed by the coinbasecartel ransomware group, with internal files reported as exfiltrated. The incident was disclosed on 19 March 2026, though the date of the breach itself has not been established; individuals should check whether their information was affected and take appropriate protective steps.
What happened
The only confirmed information is the listing itself. The group claims to have obtained internal files during a ransomware operation against Onyx Graphics. No date of intrusion, encryption, or data transfer has been disclosed. The scale of the exfiltration and whether any data was subsequently published remain unconfirmed.
Who is coinbasecartel?
Coinbasecartel is a ransomware group that maintains a public leak site to list organizations it claims to have targeted. Such groups typically encrypt systems and threaten to release stolen files if ransom demands are not met. Their listings constitute claims by the group and are not independently verified unless additional evidence emerges.
About Onyx Graphics
Onyx Graphics develops software for wide-format and grand-format digital color printers. Founded in 1989, its main products are production and RIP software used to manage print output and color control. The company operates through a network of authorized resellers serving customers worldwide. Organizations in this sector routinely hold proprietary code, customer configuration data, and operational records tied to commercial printing workflows.
What was likely exposed
The listing refers only to “internal files exfiltrated in ransomware attack.” No specific categories such as customer records, financial data, or personal information have been named. Companies of this type commonly store source code, license information, reseller agreements, and technical support files; however, the exact contents of the exfiltrated material have not been confirmed.
The real-world impact
Exposure of internal files can create operational risks for the affected organization, including potential loss of intellectual property or disruption to client workflows. For individuals or partner companies whose information appears in those files, the main concerns are unauthorized access to technical or contractual details rather than mass personal-data misuse. The absence of a reported count of affected people limits precise assessment of downstream consequences.
Were you affected?
Individuals who have interacted with Onyx Graphics or its resellers can monitor official statements from the company. A practical first step is to review any recent password-reset notices or unusual account activity. Readers may also run a free exposure scan of their email address against known breach data sets 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.
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.
