Abstract: The present invention relates to a referrer verifying apparatus and a method thereof to control a web traffic of malicious codes. The referrer verifying method comprises the steps of: checking whether a referrer exists in an HTTP packet; extracting URL from a referral web page corresponding to the referrer when the referrer exists in the HTTP packet; verifying the referrer based on a URL matched with a referrer verification request from a server, and the extracted URL; and performing a capture verification procedure by a user on the basis of the referrer verification result. [Reference numerals] (100) Server; (200) Referrer verifying device
