Description

On September 16, 2024, Heinrich-Böll-Gesamtschule and Rurtal-Gymnasium in Düren experienced nearly simultaneous server failures resulting from coordinated cyberattacks. The City of Düren responded within hours by forcibly disconnecting all municipal school servers from the network to contain potential damage escalation. Authorities immediately engaged the Aachen Police Cybercrime Unit, which assumed primary investigative responsibilities. Third-party IT service providers contracted by the schools initiated forensic examinations of the compromised systems concurrent with law enforcement activities. Initial assessments indicated no operational impact on Düren's city administration networks, which remained segregated from educational infrastructure.

The proactive server isolation affected all city-managed schools beyond the two confirmed targets, creating widespread temporary disruption to digital educational resources. Municipal officials publicly confirmed the containment strategy prioritized preventing lateral movement across school networks, though no evidence emerged suggesting broader penetration beyond the initial victims. Technical teams projected server restoration within several days based on preliminary damage evaluations. No ransomware claims, data exfiltration evidence, or attacker attribution details were disclosed by investigating entities during the immediate response phase. The incident caused significant operational interruptions to academic activities reliant on networked systems at both schools.
