Cyberattack Hits Maryland County That’s Home To NSA Headquarters

Anne Arundel County, Maryland—home to several federal agencies and the US Naval Academy—has been hit with a multi-day cybersecurity attack blamed on “external origin.” 

“The county is taking the most proactive approach to ensure our systems are safe. Precautionary measures include limiting access to the Internet until we are able to return to full operations,” the Anne Arundel County Government posted on X.

The county said, “Based on our conversations with cyber specialists, this is a multi-day event. We do not have a timeline for full service restoration yet,” adding, “We are engaging with each department to identify and discuss their current state of operational needs.”
