Parents learned on Wednesday that hackers attempted to steal information from thousands of school districts nationwide, including four in Door and Kewaunee counties.

The student records information system PowerSchool notified districts of the cybersecurity threat on Wednesday that a threat actor accessed several databases on December 22nd. The information stolen included names, demographics, addresses, emails, and phones. The threat actor contacted PowerSchool on December 28th, and the company paid a ransom to prevent the data from being released. PowerSchool has since secured its systems by deactivating compromised credentials, resetting passwords, and strengthening its security controls. Nationwide, PowerSchool supports over 50 million students, including those attending Sturgeon Bay, Algoma, Luxemburg-Casco, and Sevastopol schools. Sturgeon Bay School District addressed the cyberattack Wednesday afternoon, ensuring parents that the breach only impacted PowerSchool and not their other systems.

PowerSchool has told school districts the incident is contained and will contact them if other issues arise.
