Trinkwasserverband Stader Land

Trinkwasserverband Stader Land, also known as TWV Stader Land, is a German organisation headquartered in Germany. Its primary function is the provision of drinking water services. The organisation operates within the critical infrastructure sector, specifically focused on ensuring the supply of potable water to its designated service area. As a water utility, its core responsibility involves managing the infrastructure and processes necessary for sourcing, treating, and distributing safe drinking water to consumers.

This organisation experienced a significant cybersecurity incident on August 1, 2023. The cyber attack caused technical disruptions impacting its operational systems, notably affecting internal email communications. Crucially, the water supply infrastructure itself remained uncompromised, ensuring continued delivery of water to consumers. The incident was formally reported to both law enforcement authorities and relevant data protection oversight bodies. Initial external analysis indicated potential involvement of the LockBit ransomware group; however, the organisation later clarified that no data was actually encrypted for the purpose of a ransom demand. External cybersecurity experts were engaged to assist with the secure restoration of the affected IT systems, highlighting the reliance on specialised support for incident recovery within this critical infrastructure provider.
