Description
A cyberattack targeting multiple Bremen government agencies and the Bremen Police occurred on the evening of Tuesday, December 16, 2024, though public disclosure came the following day on December 17. The assault primarily affected the Health Department, Social Department, and Construction Department, alongside the Bremen Police force. Attackers exploited interactive contact forms embedded in the agencies' websites as the initial intrusion vector. A botnet subsequently flooded official email inboxes with spam messages, with the Health Department alone receiving approximately 2,000 emails within a short timeframe. The coordinated nature of the attack overwhelmed digital communication channels across multiple critical service departments simultaneously. While the exact technical mechanisms weren't disclosed, the scale suggested automated exploitation of web form vulnerabilities to deliver malicious payloads or disrupt operations through email saturation. Authorities restricted operational details citing ongoing investigative requirements, though confirmed the attack's focus on communication infrastructure rather than data exfiltration at this stage.
In immediate response, Bremen's Finance Department—acting as the coordinating authority—ordered the complete deactivation of all interactive contact forms across affected agency websites to contain further exploitation. This measure severed a primary public communication channel while forensic analysis commenced. Alternative contact methods were established through the existing citizen hotline (115) for departmental inquiries and the police central number (362-0) for law enforcement needs. The incident caused significant disruption to digital public services, particularly impacting departments handling health, social welfare, and construction permits where online forms constituted essential service delivery mechanisms. No data breaches or system compromises beyond the email flooding were confirmed in initial assessments. Restoration timelines remained unspecified as of December 17, with authorities prioritizing system integrity verification before reactivating digital services. The operational shift to telephone-based interactions created temporary bottlenecks in citizen-facing operations across all targeted agencies.
