Defender of Hackers Probed in Major Cyberattack

Sven Olaf Kamphuis, who calls himself the “minister of telecommunications and foreign affairs for the Republic of CyberBunker, is at the heart of an international investigation into one of the biggest cyberattacks identified by authorities. He has not been charged with any crime and he denies direct involvement, but because of his outspoken position in a loose federation of hackers, authorities in the Netherlands and several other countries are examining what role he or the Internet companies he runs played in snarling traffic on the Web.
