"Exploitable Redirects on the Web: Identification, Prevalence, and Defense"


Web sites on the Internet often use redirection. Unfortunately, without additional security, many of the redirection links can be manipulated and abused to mask phishing attacks. In this work, we prescribe a set of heuristics to identify redirects that can be exploited. Using these heuristics, we examine the prevalence of exploitable redirects present in today's Web. Finally, we propose techniques for Web servers to secure their redirects and for clients to protect themselves from being misled by manipulated redirects.

This work was presented at the USENIX Workshop On Offensive Technologies (WOOT) in July, 2008. Subsequently, several online press venues have covered it, including The Washington Post, SC Magazine, and Herald Times.
