I checked the link & it looks like they actually use paypal.com's own addy with a buffer overflow condition to make it point to a new address, which contains a page wanting you to fill in all your information. New "page" is actually on some porno site. To the average user, it would "look" like a perfectly fine email.Dear paypal user, We would like to inform you that we are upgrading our server to install a better protection software. So please click here and fill in the registration form again to renew your account. Paypal Administration.
If you go directly to paypal manually, theres nothing about an upgrade whatsoever. I've forwarded it to Paypal already to have them take action.
