The Record, part of Recorded Future News, reported on 16 October that Anne Arundel County, Maryland, confirmed a data breach. A county spokesperson said staff spotted odd activity on 28 August. An outsider had entered a small number of systems and made copies of some files, the county said. It told federal law enforcement and other agencies. The Record said the Rhysida ransomware gang claimed the attack and threatened to publish 2.6 terabytes of stolen documents unless paid $2 million.
The Record's report has no county comment on Rhysida's claim, the 2.6 terabyte size or the $2 million demand. The spokesperson did not say what data was involved. Investigators are still checking whether the files hold resident information. The Record does not say how the attackers got in. The county called this a separate incident from last year's attack by a different group.
As general context, a small number of systems says how far an intruder got, not how much data sat there. One file server can hold terabytes. Because the county gave no volume, the gang's figure can be neither confirmed nor ruled out. Stealing files is also separate from locking systems. Teams can ask what data each system holds, how long it is kept, and whether large copy-outs are watched.
