Hackers have placed data that was captured on the dark web three weeks ago during a hack at educational institution ROC Mondriaan in The Hague.

The data contains sensitive information, such as complaints handling and personal data of teachers and students.

A spokesperson for ROC Mondriaan confirms to NU.nl that there was a ransomware attack.

The data, viewed by NU.nl, was shared on a hacker site on the dark web, the protected part of the internet.

The data was stolen in a ransomware attack.

According to a spokesperson, hackers asked "a very high amount", which has not been paid in consultation with the Ministry of Education, Culture and Science.

The data shared by the hackers contains a lot of sensitive information, such as class lists, emails to parents and personal data of students and teachers.

Furthermore, the school's financial records and business protocols have been leaked.

According to the educational institution, new computer systems are now being used, with which safety must be guaranteed in the future. Teachers and students also have to reset passwords and ROC Mondriaan, which has 27 schools in the Netherlands, adds extra layers of security to the login.
