Google has announced this week that it has removed over 11 million+ domain names from its search listing with the ending .co.cc in an attempt to help reduce spam and malware sites within its listings.
The .co.cc is not an officially authorised second-level domain like .co.uk, but just a domain name which is owned by a Korean company that is offering and sells subdomains for it. These subdomains are often registered in bulk and commonly used to distribute malware and spam.
Over the past few months, Google’s systems have detected a number of bulk subdomain providers becoming targets of abuse by malware distributors. Bulk subdomain providers register a domain name, like example.com, and then sell subdomains of this domain name, like subdomain.example.com.
It will be interesting to see how the move affects the growth of malware and spam site, and also how it affects the perception of sub domains across the web as Google might need to pull more and more in its attempt to control spam and malware from its searches.
