Description
On April 18, 2022 (Easter Monday), Reitzner AG and Donau-Stadtwerke (DSDL) in Dillingen, Germany, suffered a coordinated cyberattack. The breach against Reitzner AG occurred in the early morning hours, resulting in the complete encryption of their operational systems. A limited number of customer systems connected to Reitzner's infrastructure were also compromised, with some fully or partially encrypted. The company activated its emergency response team immediately to assess all affected customers. Reitzner AG fulfilled all mandatory data protection obligations without delay, including direct notifications to impacted customers, formal reporting of the incident to data protection authorities, and filing a criminal complaint with police.
The Bavarian State Criminal Police Office's Cybercrime Division launched an investigation on the afternoon of Easter Monday, though data analysis remained ongoing at the time of reporting. Investigators confirmed the attack was a targeted intrusion executed by one or more specialized threat actors. These individuals demonstrated significant technical capability and criminal intent, deliberately bypassing Reitzner AG's security systems to gain unauthorized access. No operational disruptions or additional impacts affecting Donau-Stadtwerke were detailed in the available report. The forensic examination continued to determine the full scope of compromised data and attack methodology.
