Berlin administration data leak: Rhysida releases 1.4 million files on dark web

The hacker group Rhysida has released approximately 1.44 million stolen files from the Berlin municipal administration on the dark web. This follows the city's refusal to pay a ransom of 30 Bitcoin, equivalent to roughly 2 million euros.

The leaked data, totaling about 5.26 terabytes, includes highly sensitive information. This includes personal documents of state employees—such as birth certificates, work evaluations, and salary information—as well as critical infrastructure plans. Specifically, documents related to chemical, biological, radiological, and nuclear (CBRN) emergency response planning, as well as details regarding the protection of power plants, water supplies, and defense-related companies, have been exposed.

Berlin Mayor Kai Wegner confirmed the city would not yield to extortion, stating that the administration cannot be intimidated. The cyberattack, which occurred between August 7 and 12, previously forced the disconnection of the housing and environment departments from the network for one week. Experts and politicians, including CDU's Roderich Kiesewetter, have warned that the breach poses a significant threat to national security and the state's ability to defend critical infrastructure.
