## Article

Anne Arundel County in Maryland has confirmed that its government systems were breached in August, resulting in unauthorized access and file theft. This incident was discovered on August 28 when irregular activity was detected on a limited number of systems within the county's network, prompting an investigation. According to a county spokesperson, certain files were copied by an intruder during this breach. While the specific data affected has not been disclosed, investigations are ongoing to assess whether any resident information was compromised. Anne Arundel County, which includes the state capital of Annapolis and is home to over 600,000 residents, hosts numerous federal agency offices, making the breach particularly concerning. The Rhysida ransomware gang has taken responsibility for the attack, demanding a $2 million ransom to prevent the release of 2.6 terabytes of stolen documents. This group has a history of targeting government entities worldwide, including recent attempts to extort Berlin's government. Notably, Anne Arundel County experienced a separate ransomware attack last year by a different group, and officials are now preparing to notify residents about data leaks from that incident as well. The county has informed federal law enforcement and other government agencies about the current breach. A spokesperson noted a rise in such cybercrimes targeting state and local governments, with recent attacks causing service disruptions in numerous states across the U.S.
