PITTSFIELD, Mass. — District students and teachers had their personal information accessed as part of a worldwide PowerSchool breach.

"This is not unique to the City of Pittsfield," Superintendent Joseph Curtis told the School Committee on Wednesday.

"Every one of the 18,000 PowerSchool customers has experienced a data breach. We were informed yesterday with a very brief notice from PowerSchool and our technology department began to dig into the impact near immediately."

The breach reportedly took place between Dec. 19 and 28, when it was detected by PowerSchool and all accounts were locked down. It is being investigated by the FBI and a third-party cybersecurity firm.

On Jan. 8, PowerSchool hosted a webinar with the investigative team to provide school districts with further details about the situation.

The Pittsfield Public School's technology department investigation found that personal information from the fields "Student" and "Teacher" were accessed. This includes home addresses, phone numbers, and email addresses.

Other school districts have reported access to student grades, health information and Social Security numbers. 

As a cybersecurity computer science student, School Committee member William Garrity found the breach "deeply concerning."

"I am concerned by the security practice PowerSchool had implemented before this," he said.

"I think there was a lot of this oversight, I'm not going to get into it in this meeting. Hopefully not just us but other districts around Massachusetts, the county, and the world hold PowerSchool accountable for their security practices."
