Hackers attack Wisconsin court system computer network

Posted on March 26, 2023 by Dissent

Earlier this week, AP reported:

Hackers have attacked the Wisconsin court system’s computer network, court officials said Thursday. A cyberattack began early this week, according to a statement from court officials. Network users may have experienced intermittent service or slower than usual response times from online services, court officials said. Asked when specifically the attack began and if it’s still ongoing, courts spokesman Tom Sheehan said in an email that he had no further information.

The Milwaukee Journal Sentinel reported that this was a DDoS attack.

On March 23, the court system posted the following notice on their website:

Wisconsin court system responds to network disruption

Madison, Wisconsin – March 23, 2023

Some Wisconsin court system computer network users, including the general public, may have temporarily experienced intermittent service or slower than usual response times to some online services early this week.

The Wisconsin court system has taken effective counter measures against a denial of service (DoS) attack that targeted the court system, said Director of State Courts Randy R. Koschnick.

The cyberattack temporarily slowed networks but did not result in the breach of any court data, and court operations continue as usual across the state, said Wisconsin Supreme Court Chief Justice Annette Kingsland Ziegler.

“The integrity of the court record is of paramount importance, and I want to recognize CCAP (Consolidated Court Automation Programs), our state agencies and law enforcement for addressing this situation quickly and effectively,” Ziegler said.

Attorneys or self-represented litigants who may have experienced difficulty timely eFiling documents should contact the clerk of circuit court in the appropriate county.

There has been no update since then.

Was there anything going on that would lead any hacktivists to attack that way, or was  this something nonnpolitical?  Right now, officials either do not know or are not saying.
