A February cyberattack compromised confidential data of patients who received care from the Anne Arundel County Department of Health, officials said.
For the first time Thursday, county officials offered greater detail about the breach that temporarily closed county government buildings and disrupted several services for residents.
Officials said in a news release that the county first became aware of the attack Feb. 22 and immediately commissioned an investigation into the extent of the breach “with the assistance of industry-leading cybersecurity specialists, law enforcement partners, and relevant state agencies.”
“The ongoing investigation determined that the incident originated externally from a threat actor and was a ransomware attack,” the county said, explaining that “a limited subset of the county’s network” was infiltrated between Jan. 28 and Feb. 22.
