Abstract
Provided are a virtual server and method for identifying a zombie, and a sinkhole server and method for integratedly managing zombie information. The virtual server includes an authentication processing module authenticating a host using a CAPTCHA test and providing a cookie to the authenticated host when a web server access request message received from the host does not include a cookie, a cookie value verification module for extracting a cookie value from the web server access request message and verifying the extracted cookie value when the web server access request message includes a cookie, a web page access inducement module for inducing the host to access a web server when the cookie value is verified, and a zombie identification module for blocking access of the host when the cookie value is not verified, and identifying the host as a zombie when the number of blocking operations exceeds a threshold value.
