Denmark School District: Denmark School District staff raise concerns over data breach response

Denmark School District Faces Backlash Over Ransomware Incident and Lack of Transparency

In January, the Denmark School District in Wisconsin investigated a potential data security incident after reportedly receiving a ransom note despite initially claiming there was no evidence of unauthorized access to employee tax information. The incident came to light during a school board meeting on Monday, where staff members criticized the district’s handling of the breach, citing a lack of transparency.

Fourth-grade teacher Meagan Holewinski expressed frustration, questioning why employees were not immediately notified on January 30 or advised to take precautionary measures if their data was compromised. At least 60 current and former staff members were affected by the breach.

The district stated it engaged cybersecurity professionals to assess the scope of the incident and promised updates, though none have been provided to date. The discrepancy between the ransom note and the district’s initial denial of unauthorized access has raised concerns among employees about the accuracy of the information shared.
