comcom-sgc Listed by nokoyawa Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

In a threat landscape where ransomware groups routinely list public-sector bodies on leak sites to pressure payment, a April 2023 claim involving a French intercommunal authority fits a familiar pattern. Local government entities hold operational records and resident-related data that can be valuable to criminals and disruptive if exposed, even when the full scope of an incident remains unclear.

On 9 April 2023, the organisation identified as comcom-sgc was listed by the Nokoyawa ransomware group. Public reporting describes the claim as involving internal files exfiltrated in a ransomware attack. The number of people affected is unknown, and independent confirmation of the listing’s full details has not been established in the available record. The incident matters because it concerns a former community of communes in eastern France whose residual or successor functions touch local administration and the people who rely on it.

Breaking down the breach

According to the reported facts, comcom-sgc appeared on a Nokoyawa-associated listing dated 9 April 2023. The group’s claim centres on a ransomware attack in which internal files were said to have been exfiltrated. No public figure has been given for the volume of data, the number of systems involved, or the precise date the intrusion began or was discovered. Methods of initial access, dwell time, and whether encryption was deployed alongside theft are undisclosed. The count of individuals potentially affected is unknown. What is stated is limited to the leak-site listing itself and the characterisation of the material as internal files taken in a ransomware incident. Treat the listing as an unverified claim by the group unless and until further confirmation appears.

Who is nokoyawa?

Nokoyawa is a ransomware operation that became publicly visible in 2022 and has been observed conducting double-extortion campaigns: encrypting systems while also stealing data and threatening to publish it if a ransom is not paid. The group has typically targeted organisations across multiple countries and sectors, often through common initial-access routes such as exploited vulnerabilities, compromised credentials, or commodity malware, though specific access methods vary by incident and are not always published. Like other ransomware brands of the period, Nokoyawa has used dedicated leak sites to name victims and, in some cases, to stage samples of stolen data as proof. Public reporting has linked the name to activity that sometimes overlapped with tooling or affiliate patterns seen in the wider ransomware ecosystem after the disruption of larger groups, but those connections are assessments rather than settled attributions for every case. For this incident, the only direct assertion is the group’s own listing of comcom-sgc; no additional claims by Nokoyawa about this victim beyond that listing are stated in the facts.

About comcom-sgc

Comcom-sgc refers to the community of communes of Grand Couronné, a former French communauté de communes in the department of Meurthe-et-Moselle, in the Grand Est region. Created in 2003, it merged on 1 January 2017 with the neighbouring Community of Municipalities of Seille et Mauchère. Intercommunal bodies of this type coordinate shared local services—such as planning, waste, economic development, or administrative support—across member municipalities. Even after a merger, legacy systems, archives, and staff records can remain relevant to successor structures and to residents who interacted with the former entity. A breach affecting such an organisation is consequential because local public administration sits close to citizens’ everyday dealings with government, and disruption or exposure of internal material can affect continuity of services and trust in how municipal data is handled.

The information in question

The facts name the exposed material only as internal files exfiltrated in a ransomware attack. No inventory of file types, databases, or personal-data categories has been disclosed, and the number of people affected remains unknown. Organisations of this kind typically hold administrative documents, correspondence, contracts, HR and payroll-related records, and information tied to local services and residents. Whether any of those categories were present in the stolen set is unconfirmed. Exact contents should not be treated as established fact on the basis of the listing alone.

Why it matters

For people who had dealings with the former community of communes or its successor arrangements, the practical risk is that internal files—if they included personal or contact details, case notes, or identifiers—could be misused for phishing, social engineering, or other fraud. Even purely operational documents can reveal processes, vendor relationships, or infrastructure details that aid further attacks. For the organisation and any successor body, a ransomware event can mean operational downtime, recovery costs, legal and regulatory follow-up under French and European data-protection rules, and reputational harm. Because scale and data types are unconfirmed, the concrete impact on any given individual cannot be stated with precision; the prudent stance is to assume that exposure is possible until clearer inventories emerge.

If your data was in this claimed breach

If you believe you may have been connected to comcom-sgc or the Grand Couronné intercommunal structures, treat unsolicited contact with caution, especially messages that reference local administration, unpaid fees, or urgent account problems. Prefer official channels you already trust when checking whether anything is required of you. Monitor financial and email accounts for unusual activity, and consider updating passwords on important services, using unique credentials and multi-factor authentication where available. You can also run a free exposure scan of your email address to check whether your information has surfaced in known breach data sets. If you later receive formal notification from a public authority or successor body, follow the specific guidance in that notice.
