Stadtwerke Neumünster

Stadtwerke Neumünster (SWN) operates as a municipal utility provider based in Germany. Its core function involves delivering essential services to the local community, specifically within the Neumünster area. The organisation manages critical infrastructure related to energy supply, ensuring continuity for residents and businesses. Services impacted during a significant incident included customer data access and payment processing capabilities, indicating involvement in billing and customer account management for utilities like electricity or potentially gas and water. Maintaining the operational integrity of this critical infrastructure is a fundamental aspect of its public service mandate.

The organisation faced a severe cyber espionage attack on August 24, 2023. In response to this incident, SWN proactively initiated a comprehensive shutdown of all its IT systems to contain the threat and prevent further damage. This decisive action significantly impaired employee functionality and disrupted numerous customer-facing services for an extended period. While core infrastructure operations continued functioning, many systems remained offline. The disruption notably affected customer access to their data and the ability to process payments. The gravity of the attack led to the State Criminal Police Office (LKA) assuming responsibility for the investigation into the breach.
