Anne Arundel County, Maryland says hackers broke into county systems in August and stole files. The county said it found irregular activity on August 28, 2026, investigated a limited subset of its network, and determined an unauthorized actor copied files from a limited number of systems. Rhysida claimed the attack and threatened to leak 2.6 terabytes of data unless a $2 million ransom was paid; the county is still reviewing what information was taken.
Why it matters: County residents and employees may face exposure of personal or government data, and local services can be disrupted even when only part of a network is hit. Organizations, especially local governments, should review segmentation, backups, and incident response readiness, while affected residents should watch for breach notices and follow-up scams.
