Secure Network Solutions Listed by sinobi Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On November 26, 2025, the ransomware group sinobi listed Secure Network Solutions on its leak site, claiming to have carried out a ransomware attack that resulted in the exfiltration of internal files. The number of individuals whose information may be involved remains unknown, and no further details about the scope or confirmation of the listing have been made public. This development matters because Secure Network Solutions provides IT consulting and network management to other businesses. Any compromise at such a firm can touch operational systems and records belonging to its clients, even when the precise contents of the exfiltrated material are not yet clear.

Breaking down the breach

The incident was reported on November 26, 2025, after sinobi added Secure Network Solutions to its leak site. The only confirmed detail is that internal files were allegedly exfiltrated during a ransomware attack. No information has been released on the number of files, the duration of access, or whether any data has been published. The total number of people potentially affected is listed as unknown.

The group behind it: sinobi

Sinobi is a ransomware operation that maintains a public leak site where it lists organizations it claims to have targeted. Such groups typically gain initial access through common vectors such as compromised credentials or unpatched systems, then move laterally to locate and copy data before deploying encryption. The listing of Secure Network Solutions constitutes the group’s claim of responsibility; independent confirmation of the underlying events has not been provided in the available reporting.

Who is Secure Network Solutions?

Secure Network Solutions supplies IT consulting and network management services to businesses. Its work includes network security, infrastructure support, and cloud solutions. Organizations in this sector routinely hold configuration data, client network diagrams, authentication records, and administrative documentation that describe the internal environments of the companies they serve.

What data was at risk

The only data type named in connection with the incident is internal files exfiltrated during the ransomware attack. The exact categories of information contained in those files have not been disclosed. Firms of this type commonly store client-related technical records, but the specific contents remain unconfirmed.

Why it matters

When files from an IT services provider are taken, downstream organizations can face secondary exposure because their network details or credentials may be among the material. For individuals, the practical consequences depend on what the files actually contain, which is not yet known. The organization itself may incur costs related to investigation, remediation, and any regulatory obligations that follow.

Were you affected?

Individuals can begin by monitoring their email accounts and financial statements for unusual activity. Changing passwords for any services that may have been managed through the affected provider is a standard precaution. Organizations that used Secure Network Solutions should review their own incident-response procedures and contact the provider directly for guidance.

• Review recent account activity for signs of unauthorized access.
• Enable or verify multi-factor authentication on important accounts.
• Run a free exposure scan of your email address against known breach data.
