The hacker who earlier this month stole data from students and employees of the Hogeschool van Arnhem en Nijmegen (HAN) has put it on the internet.

RTL Nieuws

reports this on

Tuesday after viewing the data.

The hacker demanded a ransom, but the university previously said it would not pay.

The person, who is hiding behind the name 'masterballz' on the internet, then decided to put the data online.

According to

RTL Nieuws

, the stolen data is now being distributed via a popular download service.

It is unclear whether the data is also offered for sale, or whether criminals only share it with each other.

This would involve data of hundreds of thousands of people, many of which are (former) students.

Among them, full names, email addresses, dates of birth, telephone numbers and residential addresses have been leaked.

Thousands of passwords were also allegedly stolen.

These are largely from HAN alumni and not from current students.

HAN discovered the leak last Wednesday.

The school then engaged independent experts to investigate the matter.

HAN has also filed a report with the police and reported the leak to the Dutch Data Protection Authority.
