The submitted report does not reveal anything new about the previously announced possible target groups of the data breach but provides more detailed information on the data content that may have been accessed.
The estimated number of people that may have been affected by the data breach has been updated to 96,700 learners and their guardians. The previous estimate of the number of learners was 150,000. The reasons for the decrease include the deduction of overlaps in situations such as the child having transitioned from early childhood education and pre-primary education to basic education.
The analysis of the network drive that was targeted in the data breach at the end of April continues. Due to the large amount of data, completing a full analysis will require some more time.
