Re: [WEB SECURITY] Google Redirect URL actively used for Phishing




Doesn't work. Check out this old thread where we already discussed this: http://seclists.org/webappsec/2005/q1/0417.html

Plus there are plugins like WebDeveloper in Firefox that optionally turn
it off too now.  In my experience, referrer is the second most
spoofed/removed header, right after user agent.

Just a side note,

but wouldn't it be better if for example google did a check of the Referer: http header and only redirect if this is correct (and perhaps show a page instead if it isn't with a link and explanation)

This is not new. I've seen phishing sites using this technique for over a year.

I'd like to take a careful look at when new phishing techniques appear, and how long they persist. Techniques that don't succeed in fooling users will probably go away. Techniques that tip off spam filters will probably go away. Techniques that turn out to be effective will persist, at least until somebody figures out how to block those techniques. Oddly enough, using proper spelling doesn't appear to be a requirement for a phishing e-mail to be successful, since the phishing gangs still haven't started using spell checkers. I'm waiting to see whether that citibusiness web site with the two-factor auth gets phished again. Maybe 2FA made that phishing run uneconomical?

If bouncing redirects through trusted domain names has been going on
for over a year, it must be a useful technique to fool people into
clicking on links.  Maybe it's time for those well-known domains to
step up and remove those redirectors?

Brian
