Re: [Full-disclosure] Using HTTP referer for phishing attacks

This could be also used in some cases to Refer requests from paypal or
such payment systems when there is no/bad validation checks on an
e-commerce website.

ie:
if(Referer.Contains(paypal.com))
{ ok }

but what if i control mypaypal.com?

 Hi,
 
 Sorry if this is not new, but I didn't manage to find any mention of
 such a technique.
 
 In short: HTTP referer field contains information where the web user
 is coming from, which is often a trusted site such as a web search.
 Having such information, a malicious web site can use several tricks
 to fool the user into thinking that he or she returned to the
 referring site. In fact, the user is taken to a generic phishing site
 that intercepts all data exchanged between the user, the referring
 site and sites visited from the referring site.
