PowerSchool data breach victims say hackers stole ‘all’ historical student and teacher data

PowerSchool experienced a December intrusion where attackers, using stolen credentials, accessed its customer support portal and reportedly exfiltrated historical student and teacher data — including names, addresses, Social Security numbers, some medical and grade information, and teacher credentials. Multiple U.S. school districts report broad access to both current and historical records (in some cases back to 2009); PowerSchool acknowledges the breach, has notified affected customers, but has not publicly attributed the attack or disclosed full scope.
