Baltimore suburb confirms August data breach after ransomware claims

Officials in Anne Arundel County, Maryland, confirmed that hackers stole files from government systems during an incident in August. 

A county spokesperson told Recorded Future News that they discovered “irregular activity” on August 28 and began an investigation on a “limited subset of systems within the county computer network.”

“Through the course of the county’s response and investigation, it was determined that an unauthorized actor gained access to a limited number of systems and copied certain files from those systems,” the spokesperson said. 

The spokesperson did not respond to questions about what data was involved but said investigators are currently reviewing the files to determine whether any stolen information related to residents of the county. 

The Baltimore suburb is home to more than 600,000 residents and the state’s capital of Annapolis. Washington, D.C. is nearby, as well. Dozens of federal agencies have offices or headquarters in the county, including the Defense Department, the Internal Revenue Service, the Environmental Protection Agency, the Social Security Administration, the Department of Agriculture, the U.S. Coast Guard and more. 

County officials said they notified federal law enforcement about the data breach as well as other government agencies.
