Several school districts in Louisiana were affected by a possible data breach after a popular education software program was hacked, the districts said Wednesday.

The Ascension, Livingston and St. Charles school districts said on Facebook Wednesday evening that they had been informed that their districts were involved in a “cybersecurity incident” last month that targeted PowerSchool, a program that school systems across the country Use to store student and employee data. The Ascension Schools post said the district was notified late Tuesday.

The incident involved an unauthorized user gaining access to data in the software’s student information system, the district said in public notices. The data could include personal information such as names, addresses, contact information, Social Security numbers, dates of birth, selected health and class information, and names of parents or guardians, the posts said.

They added that the investigation is ongoing and the district will provide updates as more information becomes available.

In a statement to Lawyer, a PowerSchool spokesperson said the company believes the compromised data has been deleted.

“We have taken all appropriate measures to prevent further unauthorized access or misuse of the data in question,” the statement said. “The incident has been contained and we do not expect the data to be shared or made public.”

PowerSchool, which was acquired by private investment firm Bain Capital in October for $5.6 billion, serves more than 60 million students through 18,000 customers.

After becoming aware of the data breach on Dec. 28, PowerSchool notified law enforcement and retained “the services of a professional consultant with experience negotiating with threat actors,” according to the Livingston Parish Public Schools post.

“PowerSchool states that they have ‘received appropriate assurances from the threat actor that the data has been deleted and no further copies exist,'” it added.

The company also told districts that it was safe to continue using PowerSchool accounts, adding that it would offer additional services to those affected, according to the post from Ascension Public Schools.

“While we are not aware of and do not anticipate any actual or attempted misuse of personal information or financial harm to affected individuals as a result of this incident, PowerSchool will provide credit monitoring to affected adults and identity protection services to affected minors with regulatory and contractual obligations,” the company added, according to the school district’s online announcement.
