The Eclipse ransomware group has published a data leak announcement on its dedicated leak site, claiming to have targeted part02.simplexengg.in. According to the group's claim, the breach occurred on October 5, 2026. The group asserts that they have successfully accessed and exfiltrated sensitive information from the organization's internal systems.

The Eclipse group has created a formal leak announcement claiming to have targeted the infrastructure of part02.simplexengg.in. In this announcement, the group has provided a list of files that they allege belong to the organization's various administrative, technical, and operational folders. The group claims that this data was obtained directly from the organization's systems during their operation.

The group's claims involve a variety of internal documentation. Based on the information provided in the leak announcement, the captured data allegedly includes several categories of sensitive information. The following items have been identified as part of the alleged data breach:

• Accounting records

The group has provided screenshots that appear to display folder structures containing these various records, including account records, human resources data, marketing files, technical design documents, supplier lists, and administrative documents.

About part02.simplexengg.in

The firm specializes in the design, manufacture, and installation of equipment for core industrial sectors, including steel, railways, mining, and defense.

Impact and security implications

This alleged leak may have significant consequences for the organization, potentially impacting its operational continuity and commercial reputation. The publication of allegedly leaked HR and supplier data could increase the risk of identity theft or targeted phishing attacks directed at employees and business partners. Because the organization is based in India, the incident may trigger legal proceedings under relevant data protection regulations.

Publicly available information regarding the Eclipse group remains limited. However, as observed in similar ransomware cases, the publication of stolen data often leads to secondary extortion attempts, where attackers may attempt to pressure the organization through multiple channels. In such scenarios, ransomware groups use the threat of releasing sensitive information to demand payment, a tactic often referred to as double extortion.

For organizations operating in the heavy engineering and industrial sectors, such incidents highlight the importance of robust cybersecurity frameworks. Protecting technical design documents and supplier information is critical to maintaining a competitive advantage and ensuring the integrity of the supply chain. Defensive measures typically include implementing strict access controls, maintaining offline backups, and conducting regular security audits to identify vulnerabilities before they can be exploited by threat actors.
