URL Redirection
Today, websites are exposed to various threats that exploit their vulnerabilities. A compromised website will be used as a stepping-stone and will serve attackers’ evil purposes. For instance, URL redirection mechanisms have been widely used as a means to perform web-based attacks covertly. For example an attacker injects a redirect code into a compromised web site so that a victim who visits the site will be automatically navigated to a malware distribution site. Although many defense operations against malicious websites have been developed,we still encounter many active malicious websites today. The insight obtained from analyzing the observed ecosystem helps network and security operators disrupt attack campaigns in appropriate points and layers corresponding to the distinct purpose, mechanism, and strategy. For this purpose,it is essential to reveal the purposes of attacks, mechanisms of redirection, and strategies to conduct attacks to gain security knowledge in a timely manner
