"You think that you control the domains but you don't! Everybody knows wrong. We control the domains including ICANN! Don't you believe us?"

Two of the world's most important internet regulatory web sites – ICANN and IANA - were hijacked by a Turkish group called "Netdevilz" and briefly redirected to another site which screamed the above message, according to researchers at Zone-h.

IANA is the organization responsible for managing the DNS (domain name system) root zone and assigning the DNS operators for the Internet's top-level domains. DNS, which translates the domains and URLs into IP addresses, is a critical component of the Web's traffic-guiding infrastructure.

ICANN, which oversees IANA, also allocates IP address space and manages the Web's top-level domain naming system.

The zone-h researchers said the redirected domains included icann.com, icann.net, iana.com and iana-servers.com. They were hijacked to atspace.com, according to zone-h.

"We reached the defacers by e-mail but they refused to tell us how they changed the DNS records, however a cross-site scripting or cross-site request forgery vulnerability might have been exploited," zone-h said.
