"The information present in the files that may have been viewed or acquired as a result of this incident varies per person, and includes individuals names, financial account information, and Social Security Number," said PCGPS in a filing with the Office of the Maine Attorney General. No ransomware operation was specified to be behind the intrusion but the school district's data had been posted by the Rhysida ransomware group on its leak site in November. Such a development comes weeks after cybersecurity incidents were reported by the Middletown Area School District in Pennsylvania and the Central School District 13J in Oregon.
