The Minnesota Judicial Branch has restored full functionality to its eFile and eService (eFS) portal after a ransomware attack on a key vendor forced it to partially unplug the system.
On Thursday, the Branch said that around 5 p.m. on Sept. 23, vendor Tyler Technologies informed the courts it had experienced a security breach affecting that company’s internal corporate systems.
On its own website, Tyler says it discovered early Wednesday that “an unauthorized intruder had disrupted access to some of our internal systems.” The company immediately shut down external systems access points and went to work investigating and fixing the problem, it said.
“We have confirmed that the malicious software the intruder used was ransomware,” the company said. “Because this is an active investigation, we will not provide any additional specifics relating to our incident response or our investigation at this time.”
The Judicial Branch voluntarily disabled accounts from Tyler impacting transmission of eFS data, it said. “At this time, there is no evidence that the Minnesota Judicial Branch experienced any form of data breach or inappropriate access to court records and information,” the press release said.
The eFS system’s unplanned partial outage was a step taken “out of an abundance of caution,” the release said.
“The Minnesota Judicial Branch will fully restore eFS when we are confident there is no risk to our systems, data and customers,” the Branch said in a release to users. By mid-evening Thursday, full functionality was restored.
