Part1.simplexengg.in listed on Eclipse ransomware leak site

• Ransomware group: Eclipse
• Country: India
• Sector: Technology
• Announcement date: September 2, 2026

The ransomware group known as Eclipse has published a claim on its leak site involving the organization part1.simplexengg.in. According to the announcement, the threat actors have made various file directories belonging to the entity publicly available on their portal.

The claimed attack event

On September 2, 2026, the Eclipse group listed part1.simplexengg.in on its dedicated leak portal. The group claims that they have successfully accessed and exposed various file directories belonging to the organization. This announcement suggests that the organization's digital assets may have been exposed to unauthorized access by these threat actors.

Ransomware attacks often follow a pattern of double extortion, where attackers not only encrypt an organization's data to disrupt operations but also steal sensitive information to use as leverage. By publishing stolen data on a leak site, ransomware groups attempt to pressure victims into paying a ransom by threatening to release the information to the public or its competitors. This tactic increases the pressure on the victim organization, as the loss of data can lead to significant reputational damage and legal consequences.

In this specific instance, the group's claim indicates a potential breach of the organization's digital perimeter. While the announcement serves as a claim by the threat actor, it highlights the ongoing risk that organizations face from sophisticated ransomware groups that utilize public leak sites to broadcast their successes.

Data and files involved in the leak

The information provided by the group regarding the specific contents of the breach is limited. While the group claims to have access to various directories, there is no detailed information regarding the full scope or specific data types contained within these files. No information was provided regarding the total size of the data or the specific number of files stolen.

Based on the available screenshots provided by the group, specific folder names have been identified. These include:

• Account information
• NCR documents
• Hospital records

The presence of folders such as 'Account', 'All_NCRs_till_date', and 'BM_Shah_Hospital2' suggests that the leaked data may contain sensitive information. However, the full extent of the data contained within these directories remains unconfirmed by the group's announcement.

Implications and organizational risks

This leak suggests that the organization's financial and operational data may have been accessed by third parties. The names of the listed folders indicate that the organization might be processing data related to the healthcare sector, which often involves highly sensitive personal information. Such a situation could create legal obligations under data protection regulations in India.

Furthermore, there is a possibility that the leaked data could be used for malicious purposes, such as identity theft or targeted phishing attacks. When sensitive documents, such as hospital or account records, are exposed, attackers can craft highly convincing social engineering campaigns to target employees or clients of the organization.

To mitigate such risks, organizations in the technology and healthcare-adjacent sectors can implement several defensive measures. These include maintaining robust, offline backups to ensure data can be restored without paying a ransom, implementing multi-factor authentication (MFA) across all access points, and conducting regular security audits to identify vulnerabilities. Additionally, monitoring for unauthorized access and maintaining strict data encryption protocols can help protect sensitive assets from being easily readable if a breach does occur.

Summary of the threat actor

At this time, public information regarding the Eclipse group is limited. The group continues to utilize leak sites as a primary method for their extortion activities, targeting various sectors to maximize their impact and leverage.
