Anne Arundel County government officials are investigating a “cyber incident of external origin” that hampered county services over the weekend, according to a county spokesperson.

Renesha Alphonso, a spokesperson for County Executive Steuart Pittman, said the “full picture of the impact” is being determined. The service disruption started early Saturday, she added.

Government employees were instructed Sunday night to work remotely on Monday as county buildings close. They were asked to use “Google and internet-based systems” and consult with supervisors about “IT systems availability.”

County government officials in the information technology division are working with public safety officials and cybersecurity experts to resolve the problem.

“We are unable to provide much information at this time,” Alphonso said.

The county said Sunday afternoon it would be limiting its access to the internet as a precautionary measure. It described the process as a “multi-day event” with no timeline for full service restoration.

“We are engaging with each department to identify and discuss their current state of operational needs,” the county’s X post stated.

Both 911 and 311 are operational and can respond to reports of emergencies or requests for county services.

The county is the latest in a string of state entities to have experienced cybersecurity breaches over the past few years.

Local and state government agencies, health care systems, schools and universities have been targeted, resulting in service disruptions, changes to how employers guard their sensitive data and, often, expensive fixes.

On Sunday, certain pages of Anne Arundel County’s government website were not functioning, including those related to utility bill and real estate tax payments. Both tabs reported experiencing “server errors.”
