A cyberattack on a regional public safety dispatch system on the South Shore over the weekend appears to be linked to a group with ties to Russia, officials said Monday.
State and federal authorities are investigating the hack that shut down the South Shore Regional Emergency Communications Center on Saturday, according to a statement from the center.
“It has been determined that a common but fairly new form of malware reportedly originated by a group with ties to Russia,” the statement said.
It is not yet known if the attack “compromised any confidential information,” the statement said.
The center serves Cohasset, Hingham, Hull and Norwell. The cyberattack was intended to target one of its member communities, officials said.
At 9:30 a.m., staff experienced issues with its computer-aided dispatch software. While the communications system was offline, dispatchers relied on traditional and manual methods of emergency dispatch, which staff were trained to do.
“At no time was any 911 call missed or 911 service unavailable,” the organization said. “[There were] no delays of any kind in responding to emergency calls on August 2.”
Management at the center alerted its technology support systems, and communications were determined unusable for most of the day, the statement said.
The center notified its member communities, the FBI, State Police, and the Commonwealth Fusion Center, which gathers information on criminal threats to the state, the statement said.
The incident remains under investigation by the Norwell Police Department, State Police, and the FBI.
