> Ransomware gang exfiltrated student PII, parent contact data, and academic records from Indian school network.

A ransomware operator has claimed to have stolen approximately 766 MB of data from Lead Company, a school platform operating multiple Indian educational institutions. The exfiltrated dataset includes personally identifiable information on enrolled students across five named schools: Arya Vidyapith, Aakarsh International Public School, Students High School, Rainbow International Matric Hr. Sec. School, and Vignan Private School.

The compromised data encompasses multiple categories of sensitive records: student PII including full names, dates of birth, residential addresses with postal codes, and grade/class assignments; parent and guardian contact information including full names, mobile phone numbers, and email addresses; and proprietary academic metrics and classroom analytics from the LEAD school platform, including curriculum tier classifications and lesson plans. The breach appears to have involved access to the nucleus.leadschool.in administrative portal.

This represents a significant data protection incident affecting minors and their families at scale. The exposure of student dates of birth, home addresses, and parent mobile numbers creates severe risks for targeted phishing, voice-phishing, identity theft, and physical targeting. Defenders and incident responders should treat this as a credential compromise and unauthorized access incident requiring investigation of administrative portal access logs, user authentication, and data exfiltration paths.
