RansomHub ransomware group lists www.cyncsolutions.com on its leak site

• Ransomware group: RansomHub
• Country: United States
• Sector: Technology
• Announcement date: June 4, 2024

The RansomHub ransomware group has published a listing on its leak site claiming that it has compromised data belonging to the technology company cyncsolutions.com. The announcement, which appeared on June 4, 2024, suggests a significant breach targeting the organization's core service infrastructure.

The nature of the alleged attack

According to the claims made by RansomHub, the threat actors successfully gained unauthorized access to the backup infrastructure of cyncsolutions.com. This breach appears to have specifically targeted the disaster recovery backup services provided by the company. By infiltrating these systems, the group alleges that they were able to reach sensitive data belonging to various third-party clients served by the organization.

The threat actor's announcement explicitly states that both backup files and critical company data belonging to the company's clients have been compromised. This type of attack pattern is characteristic of modern ransomware operations, where attackers aim to maximize leverage by targeting the very systems intended to protect data integrity and availability.

Data and evidence provided by the group

While the specific volume of data and the exact file counts have not been disclosed by the group, the leak site provides visual evidence to support their claims. The screenshots provided by the attackers display various directory structures related to S3 storage buckets and various backup files. Furthermore, the group has shared names of several clients that they claim are affected by this incident, including Harman Realtors, CableConn, and Murill & Gerbino LLC.

The listing identifies the following types of affected information:

• Third-party client backup data
• Corporate backup files

Analysis and potential implications

This incident may reflect a strategic move by the RansomHub group to create a wide-reaching impact through supply chain attacks. Because cyncsolutions.com provides specialized disaster recovery services, the exposure of this data could pose significant secondary risks for its clients. When a service provider is compromised, the downstream impact on their customer base can be substantial, as the breach extends beyond the initial target.

The exposure of client data through such a breach may lead to various risks for the affected organizations, including the possibility of identity theft and the execution of targeted phishing attacks. For a company based in the United States, such an incident may also lead to legal consequences under state-level data breach notification laws and potential sectoral regulations.

In the broader context of cybersecurity, this event highlights the critical importance of securing backup and disaster recovery environments. Organizations in the technology and service sectors often serve as high-value targets because a single successful breach can grant access to the sensitive information of numerous third-party entities. To mitigate these risks, organizations typically focus on implementing robust access controls, monitoring for unauthorized changes to storage bucket configurations, and ensuring that backup environments are isolated from primary production networks.

Regarding the threat actor, public information about RansomHub remains limited. It has been reported that the group ceased operations in early 2025.
