Hogeschool van Arnhem en Nijmegen (HAN)

Hogeschool van Arnhem en Nijmegen (HAN) was targeted by hackers who stole data from students and employees and put it on the internet. 

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

The person, who uses the pseudonym ‘masterballz’ on the internet, then decided to put the data online and the stolen data is now distributed via a popular download service.
