Madera County Superintendent of Schools Listed by Qilin Ransomware Group

On December 25, 2025, the Madera County Superintendent of Schools appeared on the leak site of the qilin ransomware group, which claims to have stolen and is prepared to publish the organization’s internal files.

What Public Reporting Shows

Public reporting indicates the California county education office was listed on the qilin leak portal with an announcement that internal data had been exfiltrated. The exact number of files or specific records involved has not been disclosed in available reporting. No confirmation has yet emerged from Madera County itself about the volume or sensitivity of the material, but ransomware groups typically post samples to pressure victims into payment.

The incident follows the group’s standard pattern of encrypting systems, exfiltrating data before or during the attack, and then listing non-paying targets on its public leak site. As of the listing date, the files had not been broadly distributed beyond the leak portal itself.

Why This Matters for You and Your Family

When a school district or county education office is breached, the records often contain information that directly touches local families. Student directories, employee payroll files, vendor contracts, and internal email correspondence can include names, addresses, dates of birth, Social Security numbers, and medical or disciplinary notes. Once that material leaves secure systems, it can surface in unexpected places months or years later.
