Sinobi ransomware group claims breach of Secure Network Solutions

The threat actor known as sinobi has published an announcement on its leak site regarding a targeted cyberattack. According to the post, the group claims to have compromised the systems of Secure Network Solutions, a technology firm based in India. The announcement, which was made on November 26, 2025, alleges that the organization's network infrastructure has been encrypted and that a significant amount of data has been exfiltrated from their environment.

In modern cyberattacks, ransomware groups often employ a strategy known as double extortion. This method involves not only encrypting an organization's files to disrupt operations but also stealing sensitive information before the encryption occurs. By threatening to leak the stolen data on a public forum or a dedicated leak site, attackers increase the pressure on the victim to pay the ransom. This tactic aims to maximize leverage by threatening the organization with reputational damage and legal consequences resulting from the exposure of private information.

Details of the alleged attack and exfiltrated data

The claim made by the sinobi group suggests that the breach resulted in the theft of approximately 50 GB of data. While the specific file count was not provided in the announcement, the group has threatened to publish the stolen information if their demands are not met. The contents of the alleged breach are critical to the organization's operations and its relationships with external parties.

According to the information shared in the post, the allegedly exfiltrated data includes:

• Customer information
• Contracts
• Incident logs

The presence of such diverse data types—ranging from client details to internal logs—indicates a broad compromise of the target's digital environment. The group's claim that they have access to contracts is particularly significant, as these documents often contain sensitive terms and details regarding business relationships.

About Secure Network Solutions

Secure Network Solutions is a technology company that provides a variety of specialized services to its clients. The firm focuses on IT consulting, network management, network security, and cloud solutions. Their primary business model involves assisting other organizations in enhancing their IT infrastructure and ensuring they can operate securely within the digital landscape.

Given their role in providing security and management services, the organization plays a vital part in the digital infrastructure of the businesses they serve. This makes the reported breach a significant event for the sector they operate in.

Potential impact and organizational risks

This incident may negatively impact the operational continuity and customer trust of Secure Network Solutions. Because the group claims to have access to contracts, the breach could pose secondary risks for the organization's business partners and clients. Furthermore, the organization may face legal obligations under India's data protection regulations due to the nature of the alleged data theft.

There is also a persistent risk that the leaked data could be utilized by malicious actors for identity theft or for conducting highly targeted phishing attacks against the organization or its clients. Such attacks often use the specific details found in incident logs or contracts to appear more legitimate to the recipient.

In the technology and IT services sector, organizations can mitigate such risks by implementing robust defensive measures. These include maintaining strict network segmentation to prevent lateral movement, enforcing multi-factor authentication across all services, and conducting regular, comprehensive backups that are stored offline or in immutable environments. Additionally, continuous monitoring of network traffic can help in the early detection of exfiltration attempts. While public information regarding the sinobi group is limited, making a definitive assessment of their specific technical capabilities or motivations difficult, the incident highlights the ongoing threat posed by ransomware groups to service providers.
