What Happened
Berlin’s state government confirmed cybercriminals stole data from its network after the Rhysida ransomware group listed the city on its dark web leak site. Rhysida claims to hold 5.79 terabytes of data spanning roughly 1.44 million files, including judicial documents, emergency response plans, critical infrastructure details, tens of thousands of administrative fine proceedings and contracts, and personal data tied to more than 12,000 individuals. The group demanded 30 bitcoin, worth roughly $2.3 million, and set a one-week deadline before threatening to publish the stolen material. Berlin’s Governing Mayor confirmed the city won’t pay, aligning with standing EU and US law enforcement guidance against ransom payments. Rhysida has run a double-extortion ransomware operation since mid-2023, with prior targets spanning healthcare organizations, state governments, and education institutions.
Why This Matters for Canadian Organizations
Municipal and provincial governments across Canada have faced repeated ransomware incidents in recent years, and the Berlin attack follows a pattern familiar to Canadian security teams: an attacker targeting a large public-sector network holding sensitive citizen and administrative records, then applying public pressure through a leak-site auction after a ransom refusal. The scope of data Rhysida claims, spanning legal proceedings, emergency planning documents, and personal information, shows why government networks carry outsized breach impact beyond direct financial cost. Under Bill C-26 and guidance from the Canadian Centre for Cyber Security, provincial and municipal bodies overseeing critical infrastructure and citizen services face growing expectations to demonstrate ransomware resilience, including tested backup and recovery capability removing payment as the only path to restoring operations.
What to Do
Government IT and security teams should treat the Berlin incident as a prompt to verify offline, tested backups exist for systems holding administrative, legal, and citizen-facing data, not only line-of-business applications. Reviewing incident response and public communication plans ahead of an actual event, including coordination with law enforcement before any ransom conversation starts, shortens the response timeline when an attack hits. Segmenting sensitive record repositories such as legal and emergency management systems from general administrative networks limits how much data a single compromise exposes.
