Description

On 10 February 2025, the IT systems of the Secretariat of the German Bishops' Conference (Deutsche Bischofskonferenz), which also serves as the office of the Association of Dioceses in Germany (Verband der Diƶzesen Deutschlands), fell victim to a professional cyberattack. A group attributed to organized cybercrime publicly claimed responsibility for the intrusion. The attack was detected late on Monday afternoon, at which point the pre-established emergency plans were immediately activated. As an immediate containment measure, the IT systems were disconnected from the internet to prevent further unauthorized access. Simultaneously, the responsible investigative authorities and the data protection commissioner were notified of the incident. External IT forensics specialists were brought in to investigate how the attackers had managed to circumvent the multi-layered IT security systems in place.

In the immediate aftermath of the detection and disconnection, the organization's email reachability was significantly restricted due to the ongoing investigation and the deliberate separation of the IT infrastructure from the network. Forensic specialists are actively examining whether the threat actors succeeded in exfiltrating data from the compromised IT systems. The organization stated that if personal data is found to be affected by the IT security incident, the Association of Dioceses in Germany will proactively inform all affected individuals in accordance with applicable data protection regulations. The incident was publicly disclosed by the German Bishops' Conference through an official press release issued on the same day as the attack.
