Just a day after ICANN opened up domain rules, a Turkish group of hackers has messed with some of the Internet body's sites, according to a report on Zone-H.

The report says that the NetDevilz group redirected visitors to "icann.net" and other ICANN sites to a hosting space that carried the following message:

"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?"

In addition to targeting ICANN, which looks after administration of top-level domains, the hackers also went after sites belonging to IANA, which oversees IP addresses and DNS root management, Zone-H said.

But it doesn't look like the organisations' main URLS, &mdash: "icann.org" and "iana.org" — were affected, just less alternatives such as "icann.com" and "iana.com". Which makes you wonder: Once businesses are able to use any domain suffix, as approved yesterday, won't that give hackers even more scope for hijackers?
