In computer security, referer spoofing or ref tar spoofing is the sending of incorrect referer information along with an HTTP request, with the aim of gaining unauthorized access to a web site.

[edit] Application

Many pornographic paysites utilize referer information to secure their materials: only browsers arriving from a small set of approved (login-) pages are given access; this facilitates the sharing of materials among a group of cooperating paysites. If attackers acquire knowledge of these approved referers (which is often trivial because many sites follow a common template), they can then gain free access to the materials.

[edit] Tools

Several software tools exist to facilitate referer spoofing. The Mozilla Firefox extension refspoof allows to use a custom referer URL for any site one visits, and provides a mechanism to manage a bookmark list of such referer/site pairs. A similar, more comfortable plugin is spooFXplorer (not compatible with the most recent version of Firefox). QuickSpoof and Spooph provide the same functionality for the Internet Explorer browser. SuperMegaSpoof is a Windows application that supports both browsers and allows users to exchange and rate referer spoofs; it displays advertisements while it is running.
