As DataBreaches noted yesterday on infosec.exchange, the Medusa ransomware gang claims to have hit Great Valley School District in Pennsylvania. They provide a filetree showing a lot of Skyward, Canvas, PowerSchool, and other internal files, as well as 20+ screencaps of student info and employee info files to support their claim. They are demanding $600k from a district that has more than 4,000 students.
Over at SuspectFile, Marco A. De Felice has taken a deeper dive into the data. He reports, in part:
From the information we have gathered, it appears that a negotiator from the Great Valley School District contacted the Medusa Team through the chat opened by the cybercriminals. We know that the School District refused to pay the ransom.
As reported by the School District in a statement on its institutional website, the cyberattack on its computer network occurred between October 31 and November 10. In addition to the sensitive data previously described, the statement indicates that Social Security numbers, driver’s licenses, and medical information may have been exfiltrated.
However, one aspect of this incident remains unclear to us. We were able to examine some files published by the Medusa Team and can confirm that among them is at least one medical document belonging to a woman. What we find perplexing is not the presence of unprotected medical data on the School District’s servers, which is a serious matter in itself, but rather whose data it is.
