BCS ProSoft Listed by sinobi Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

BCS ProSoft, a technology consulting firm serving more than 1,500 clients, was listed by the sinobi ransomware group on February 11, 2026. The number of individuals whose information may have been involved remains unknown, and the company has not confirmed the extent of any exposure. For clients in manufacturing, healthcare, and professional services that rely on the firm for ERP systems and business-management software, the incident raises questions about the security of operational records that often contain sensitive business and personal details.

Inside the incident

The only confirmed detail is that BCS ProSoft appeared on a listing attributed to the sinobi group on February 11, 2026. The entry states that internal files were exfiltrated during a ransomware attack. No information has been released about the date of the intrusion, the volume of data taken, the method of access, or whether any data was later published. The number of people affected is listed as unknown.

The group behind it: sinobi

Sinobi is a ransomware operator that maintains a public leak site to list organizations it claims to have targeted. Such groups typically gain initial access through phishing, compromised remote-access tools, or vulnerabilities in internet-facing systems, then move laterally to locate and copy data before deploying encryption. The listing of BCS ProSoft constitutes a claim by the group; independent confirmation of the intrusion or the contents of any exfiltrated material has not been made public.

BCS ProSoft and its sector

BCS ProSoft provides implementation, project management, and ongoing support for enterprise resource planning platforms, including products from Sage, Deltek, and ARM. Its clients operate in manufacturing, healthcare, and professional services, sectors that routinely process financial records, employee data, and operational information. A breach at a firm entrusted with configuring and maintaining these systems can expose both the consultant’s own records and material that originated from client environments.

What data was at risk

The listing refers only to “internal files.” Specific categories of data have not been disclosed. Organizations of this type commonly hold client contact information, project documentation, configuration details for business systems, and administrative credentials. Without a published inventory or statement from BCS ProSoft, the precise contents of any exfiltrated material remain unconfirmed.

What's at stake

Exposed internal files could contain details that allow further targeting of the firm’s clients or reveal business processes that competitors or other actors might exploit. For individuals whose information appears in those files, the primary concerns are potential misuse of contact data or credentials and the possibility that stolen material could surface on other forums. The organization faces operational disruption and the cost of investigation and remediation, though the scale of these effects is not yet known.

What to do if you're exposed

Individuals who have worked with BCS ProSoft or its clients should monitor accounts for unusual activity and enable multi-factor authentication where available. Changing passwords for any systems accessed through the firm is a prudent step.
