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.
