RE: [WEB SECURITY] Web Hacking Incident: PayPal Phishing Site Exploits Google XSS Vulnerability

["dpw" <dainw () fsr com>]

I am surely missing something here. This seems like a pretty involved phish,
but the initial hook doesn't seem to be baited very well. 

Why would anyone think a link that goes to Google would be a legitimate way
to go to PayPal? Why would this be different than leveraging any redirect
system? Why is this noteworthy?

Now, if PayPal had some sort of reusable 404 redirection mechanism, at least
the initial link would appear to go to Paypal, but it sure seems to me that
going to Google first is pointless. Maybe the phisher is tracking the
effectiveness of the lure by watching the referrer?

Exploits Google XSS Vulnerability



        Google has a number of redirection holes just like the one
mentioned in that article, presumably to track user behavior for more
targeted ads.  In a cursory check I found four of them (these all simply
redirect to CNN):

http://froogle.google.com/froogle_url?q=http://www.cnn.com
http://www.google.com/url?sa=l&q=http://www.cnn.com/&ai=BsbPer84UQ7D7B73WsAG

http://catalogs.google.com/url?sa=H&title=PC+Connection&subtitle=&q=http://w
ww.cnn.com
http://images.google.com/imgres?imgurl=.&imgrefurl=http://www.cnn.com

        Although in my mind the only thing that makes this worse than
any other redirection attack is that it's Google, and people trust
Google for some reason.
