The Netherlands' Public Prosecution Service recently announced that a 35-year-old Dutchman, identified only as "SK," has been arrested in Barcelona for his alleged involvement in last month's DDoS attacks on Spamhaus (h/t Krebs on Security).

According to the announcement, the house in Barcelona where the man was living was searched, and computers, storage devices and mobile phones were seized. The arrest was made possible through Eurojust, a collaboration between judicial authorities throughout the European Union.

Krebs on Security's Brian Krebs reports that the DDoS attacks on Spamhaus followed soon after Spamhaus blacklisted domains belonging to Web host CyberBunker -- and SK may well be Sven Olaf Kamphuis, who was referred to in a March 26, 2013 New York Times article as a representative of CyberBunker.


Krebs also notes that a Facebook profile belonging to Sven Olaf Kamphuis says he's from Amsterdam, lives in Spain, and is the "Minister of Telecommunications and Foreign Affairs" at "Republic CyberBunker."

Kamphuis told Bloomberg earlier this month that he "didn’t directly start the hack but admits he did help coordinate a group of Spamhaus’s various antagonists."
