Pennsylvania’s largest Workers and Teachers’ Union, PSEA, has exposed the personal information of over half a million individuals. PSEA is a labor union that represents public school teachers, higher education faculty members, school support staff, and retired educators across the Keystone State.
“PSEA experienced a security incident on or about July 6, 2024 that impacted our network environment,” the organization said in breach notification letters sent on March 17, 2025 to 517,487 individuals. “Through a thorough investigation and extensive review of impacted data which was completed on February 18, 2025, we determined that the data acquired by the unauthorized actor contained some personal information belonging to individuals whose information was contained within certain files within our network.”
PSEA says the stolen information varies by individual and consists of personal, financial, and health data, including driver’s license or state IDs, social security numbers, account numbers and PINs, account usernames and passwords, security codes, payment card information, passport information, taxpayer ID numbers, health insurance and medical information.
While the workers and teachers’ union has not disclosed the threat actor’s identity, the Rhysida ransomware took credit for the PSEA data breach in September 2024 and listed the labor union on its data leak site.
A law firm is currently investigating whether affected individuals are entitled to compensation.
