Google has removed more than 11 million .co.cc websites from its search engine index.
Google has modified its malware detection system to identify sub-domain level services which have been used by criminals to register thousands of domains and host malware and fake anti-virus software. As the result of these changes, Google has removed more than 11 million .co.cc websites from it search engine results pages on the basis that most of them are spammy or low-quality.
According to a recent report by Anti-Phishing Working Group, the .cc top-level domain hosted more than 4,900 phishing attacks in the second half of 2010. This number is almost twice the number under any other extensions.
The .co.cc space offered by a Korea company (http://co.cc/) and it is not an official authorized second-level domain like .co.uk. This company as a registry offers single sub-domains for fee, and bulk register with discounted price of $1000 for 15,000 domains. The company claims to have 11,383,736 registered domains and more than 5 millions user accounts.
The .cc is the Internet country code top-level domain (ccTLD) for Cocos (Keeling) Islands, a small Australian territory in the Indian Ocean. The regular .cc websites are unaffected by Google’s changes.
