Adelaide-based public school Reynella East College suffered a second major data breach within a matter of months, exposing further personal and sensitive student information. The incident follows an earlier June 2026 ransomware attack by the Interlock group that disrupted school IT infrastructure and led to 600GB of internal files being published online. South Australia's Department for Education and school leadership launched an immediate incident response investigation, issued formal breach notifications to affected families and regulatory bodies, and engaged cybersecurity specialists to contain the breach and assess compromised systems.
