About This Breach

Hackers breached municipal data networks, heavily affecting the Senate Department for Mobility, Transport, Climate Protection and Environment, as well as the Senate Department for Urban Development, Building and Housing. After the Berlin government refused to pay a 30 Bitcoin ransom demand, the attackers leaked approximately 1.44 million files totaling 5.79 terabytes on the dark web. The compromised repository includes administrative penalty records, citizen personal data, employee HR dossiers, internal contracts, telephone logs, and system credentials.
