Abstract： As the high similarity exists in the web content of the malicious domain names, such as online gambling, pornographic etc., and the operators register a large number of domain names and deploy the same website code to circumvent domain name blocking, this paper proposes a fast verification method for malicious domain names by using image similarity clustering and similarity search. Ten thousand malicious domain name samples are selected manually in the experiment,，including 5 000 pornography and 5 000 Internet gambling domain names. The final experiment shows that the overall accuracy of the verification method is 99.67%, 99.66% for pornography and 99.68% for Internet gambling, which greatly improves the manual verification efficiency of malicious domain names.
