Overview
- Forensic checks turned up an "Inkriminierung des Landesnetzes," and the Senatsverwaltungen for Stadtentwicklung, Bauen und Wohnen and for Mobilität, Verkehr, Umwelt und Klimaschutz were cut off from the Berlin Landesnetz last Friday to stop further damage.
- Employees report they lack external email and internet access, are largely limited to telephone work, and some offices say home office is not possible, leaving daily casework effectively stalled.
- A criminal investigation has been opened and is being handled by the Landeskriminalamt, the Staatsanwaltschaft Berlin and the BSI while a Notfallkrisenstab under the state's information-security representative coordinates forensics and containment.
- News outlets report that data may have been exfiltrated and cite a suspected vulnerability linked to the land-owned IT provider ITDZ, but the Senatskanzlei says no sensitive data were lost and that the files in question were publicly available Open Data.
- Operational fallout threatens citizen services including Wohngeld and Bildung & Teilhabe payments—affecting more than 50,000 households—and has intensified criticism of Berlin's patching, fragmented IT governance and crisis communication ahead of planned parliamentary oversight.
