Notification of data breach

Home > Notification of data breach

Late last year, the information technology (IT) system of St Anne’s School, Kew East, was accessed by an unauthorised third party.

Working closely with the school and a team of cybersecurity experts, Melbourne Archdiocese Catholic Schools (MACS) began the process of forensically identifying the nature and extent of this unauthorised access.

The forensic audit has identified that the unauthorised third party may have had access to the data held by the school on its current and former staff, and current and former students and their families.

The advice we have received is that it is unlikely the unauthorised third party accessed this data or copied it from school systems.

However, given the complex nature of the attack, we are unable to confirm that with absolute certainty.
