Odds are, the site was designed to install some kind of malware on someone who, like you, was foolish enough to click on that link, but compounded it by clicking on it while using Windows and Internet Explorer. So some bit of malware would have been installed which might steal passwords, etc.
However, it is possible that the site used a XSS attack, so after closing your browser and reopening it, you may want to change the password on your facebook account again, as well as make sure to report that you did something stupid to facebook, so they can make sure to flag your account for additional scrutiny in the future. Someone could have grabbed your new password, and then also set it up so that an email address of their choosing is notified every time you change the password. Or less sophisticated, they'd just use your account to post spam in your name all over the place until you wised up.
Just remember this lesson for the future and be careful about just what links you click on. Using a Mac doesn't automatically make you immune to all threats out there, just the ones aimed specifically at Windows and/or Internet Explorer. There are plenty of social engineering techniques, like the one you fell for, which can affect Mac, and *nix users in equal measure with Windows users.
I received a fake Facebook notification of a vulgar comment supposedly on one of my postings. I foolishly clicked on the link which took me to a different page and then to Facebook. The actual link was to (DO NOT visit this site) www.omgclan.eu/e107_files/cache/fb.html.
I'm concerned about what this link was for. I immediately changed my Facebook password but then I realized that the page hadn't done anything other than forward me to Facebook, so I wonder if it installed some malware. Anyone know?
