The man police said was behind the biggest DDoS attack in the history of the Internet aimed at spam-tracking firm Spamhaus is now in The Netherlands after his extradition, officials said.
Sven Olaf Kamphuis, 35, owner and manager of Dutch “bulletproof hosting” firm Cyberbunker and of CB3ROB ISP, ended up extradited to The Netherlands last week and remains in custody while police investigate the case.
Police busted Kamphuis, a citizen of The Netherlands, in Spain in April at his home in the city of Granollers near Barcelona, which functioned as a communication center, and has apparently been circling Spain in a van equipped with computer equipment, routers, antennae and which has been a mobile office.
In a recent interview he said he was the spokesman for Stophaus, a group of organizations that actively works against Spamhaus, which has flagged them as spammers and has obviously damaged their functioning. Still, he said he is not a member, and added Chinese and Russian members of Stophaus are behind the attack.
The New York Times said police have not charged Kamphuis with anything yet, but he will stay in custody for 14 days while the Dutch Police’s High Tech Crime Team continues their investigation into the attack. When this period passes, a court will decide whether he will be free to go or will stay in custody without any charges for up to 90 days.
In the meantime, some Dutch government and business websites, including the Dutch DigiD e-signature system, have suffered hits by DDoS attacks, and some of which police said ended up executed by Kamphuis’ supporters as revenge for his arrest and incentive for his release.
