The behavior of this particular scam is too cause a link to be posted BY YOU on all of your friends' walls. (There is another popular one going around -- "See Who Viewed Your Profile" -- that behaves in the same way. Facebook confirms that there is no app that can do that, and encourages us to use the "REPORT" feature when we see that.
If you click the link, many geeky "redirections" (described at end of article) happen before you end up on a page that looks like this:
The danger starts if you click "Watch Video". DON'T DO IT!
While it would be interesting to explore the Cross Site Scripting vulnerability that allows this to happen, the more important thing to share is "what should a FaceBook user who sees this activity do about this offending post on their wall?"
Whenever you see something objectionable on your wall, the thing to do is REPORT IT!
Hover your mouse over a message on your wall, and a grey "X" will appear at the top right of the message.
When you click the "X" by the top right corner of the wall post, you are presented with a drop down menu. We're going to choose the bottom item -- "Report As Abuse"
Since the post is not "about me", we go to the lower section and choose "Spam or scam"
When we click "OK" we get an option to block the user. Since this is an innocent mistake by our friend, we don't want to "block" the friend, so just check the bottom box that says "Report to Facebook." If our friend is the sort of helpless, clueless individual that clicks on everything they see, eventually we would want to block this friend.
We get a nice "Thank you" from our friends at Facebook Security! These really help the team! They get the messages and use them to prioritize what things need to be addressed. If many reports are received for the same link, or about the same user, those things get addressed more quickly. Different types of reports go to different sub-groups so just because they are busy helping fight something like today's report doesn't mean that they ignore cyber-bullying.
Facebook WANTS YOU to report things that bother you. That's how they keep a clean neighborhood.
Help them help you. REPORT SCAMS!
Then take a moment more and send your friend a friendly message letting them know what's going on. They might want to let the rest of their friends know.
Facebook security has several recommendations, including a couple that I honestly wouldn't have thought of. (I'll put those first)
- Unlike the page which tricked you into showing fake video and report them immediately to Facebook. -- in addition to posting the message to your friends' walls, this tricky Facebook worm causes you to "Like" its page. The more "Likes" a page has, the more people are convinced it's real, so it is helpful to go "UNLIKE" the page. (if you've liked it, it will be a choice on the left side menu.)
- If a friend is posting suspicious messages to your wall, they may have malicious software on their computer, or may have clicked something bad themselves. Facebook Help says the best thing to do is tell your friend to contact Facebook Help.
- If YOU are the one posting the message, this Facebook Help post is for you: Wall posts were sent from my account, and I didn’t send them. It has helpful hints about anti-virus, not clicking on spam, and how to reset your password.
- Have up-to-date anti-virus software
- Keep an eye for messages that often feature misspellings, poor grammar and nonstandard English. If it doesn't look like a message your friend would type, REPORT IT! It may be related to malware or a malicious app that is using your friend's account!
- Do not open spam mails, including clicking links contained within those messages.
- Don’t copy and paste any scripts in your Facebook profile. Several scams have worked by encouraging you to paste something odd in your profile. Some of those scripts install apps, grant permissions, or make you do things you wouldn't want to do!
- If you’re using Chrome, make sure you don’t paste any scripts in your browser bar, as the browser tries to preload anything you type in the ‘awesome’ bar.
Geek Alert!
Here's an example stream of what happens if you click one of these links ...
In this case, the link is going to pass through several rounds of redirection, which we can see by doing a "wget" of the destination URL. A "301" command makes your browser move on to another web address without really adding any new content.
In the top example, the destination URL is tinyurl.com/3b8uayr
wget http://tinyurl.com/3b8uayr

Trying a new setting. After turning on comments, I got about 20-30 comments per day that were all link spam. Sorry to require login, but the spam was too much.
