On February 10, 2025, Stadtgemeinde Tulln experienced a cyberattack that encrypted data across its municipal server infrastructure and approximately 200 individual workstations. The attack disrupted digital services while critical public infrastructure operations continued without interruption. Core citizen services like registrations and certifications were restored through temporary solutions, whereas functions requiring access to stored data, such as electronic document processing, remained impaired. Most encrypted files are expected to be recovered from validated backups, although one day of recent operational data was irretrievably lost. Restoration efforts have prioritized gradual system reactivation under close monitoring for suspicious activity. Investigations into potential data exfiltration are ongoing in coordination with law enforcement, and no response has been received from the perpetrators following initial contact.
