The Rhysida ransomware group published 5.79 TB (about 1.44 million files) of Berlin state administration data on its leak site on August 28, 2026, after the city-state refused a 30 Bitcoin ransom. The claimed dataset includes personal data on 12,076 individuals, over 5,000 personnel files, payroll records, plaintext credentials for systems like PAYONE and Z_ADMIN, Bundesrat committee protocols, and documents allegedly containing state secrets. Leaked material reportedly covers national defense emergency plans, federal secret communication channels, a CBRN threat planning folder, and vulnerability analyses of Berlin's water supply. Berlin's government has activated a central crisis unit to review the leaked data and notify affected citizens and businesses.

Rhysida Publishes Berlin Government Data After €2m Extortion Demand Refused

Rhysida published 5.7 TB of Berlin state government data, including sensitive CBRN emergency plans, after the state refused a €2m ransom demand.

The Rhysida ransomware gang leaked roughly 5.7 TB — about 1.4 million files — stolen from Berlin's state network after the government declined to pay 30 bitcoins (about €2m) by the September 4 deadline. The dump reportedly includes sensitive state emergency plans for terrorist attacks and CBRN disaster scenarios in a folder titled 'AG CBRN-Rahmenplanung', plus personnel files, absence lists, payroll data, and home addresses, potentially affecting tens of thousands of people. Berlin says there are no indications the state network remains compromised and will notify affected individuals on a risk-based basis after forensic analysis.

Berlin says it won’t pay ransom after hackers steal government data

Berlin refuses ransom as Rhysida ransomware group claims theft of 5.79 TB of government data ahead of September 20 elections.

The Rhysida ransomware group claimed responsibility for stealing 5.79 TB of data from Berlin's government network, including 46,500 contracts, emails, phone numbers, passwords and classified information, and listed it for auction starting at 30 bitcoin (~$2.3 million). Berlin discovered the breach in mid-August, disconnected two ministries from the state network on August 14, and refused to pay the ransom; authorities have not officially attributed the attack. Data is believed taken between August 7 and 12, and district services such as housing benefit processing were disrupted. Officials said election infrastructure is protected ahead of the September 20 House of Representatives vote, and state IT provider ITDZ Berlin was unaffected.
