Abstract
Malicious redirects in a redirect chain as a result of loading a web address are detected and blocked. A suspicion score is determined for a subject redirection domain based at least in part on the subject redirection domain's web address, and a rate of occurrence of the subject redirection domain in redirect chains leading to a malicious landing domain is calculated. Loading the subject redirection domain is blocked if the suspicion score exceeds a suspicion threshold or the rate of occurrence of the subject redirection domain exceeds a rate of occurrence threshold.
