The 17-year-old is suspected of hacking at KPN held on 16 January. He was arrested last Tuesday. The police seized a encrypted computer, two laptops and data carriers. During the hack the hacker obtained access to hundreds of servers from KPN. Possibly because of poor security of the company itself. There was controversy when details were published on the Internet, but these were from another hack, namely shop Babydump.nl
The boy used the aliases xS, and Yui Yoshioka. On a chat channel of Korean students he would have bragged about the digital intrusion. The cyber team followed him for weeks on the internet. The boy is therefore suspected of hacking the Tokohu University in Japan, the University of Trondheim in Norway and the KAIST in Korea.
