Forget those phishing emails that attempt to get your credit card or  bank sign-in information. When crooks want to know how to get into your  bank account, they post a message on Facebook. These messages appear so  innocuous and so appropriate in the Facebook setting that you are likely  to not only get conned, but pass on the scam.
Facebook is the new frontier for fraud, says Tom Clare, head of  product marketing at Blue Coat, an Internet security company that does  annual reports on web threats. In just this past year social networks  have soared to 4th from 17th most treacherous web terrain -- behind porn  and software-sharing sites, which you probably know to avoid.
What  makes Facebook so treacherous? Us.
It starts with the fact that  we are inundated with requests to set up passwords to get into our work  computers, our online bank accounts, Facebook and every other web-based  subscription. So what do we do? We use the same password.
"Crooks  understand that most users use the same password for everything," says  Clare. "If they can get your user credentials for your Facebook account,  there's a good chance that they have the password for your bank  account."
If you are smart enough to have separate passwords for  Facebook and your financial accounts, crooks get at you through a  variety phishing attempts that you might think are Facebook games and  widgets. But look closely and you'll realize that they deliver answers  to all of your bank's security questions -- and possibly clues to your  passwords -- right into the hands of the crooks.
Think it couldn't  happen to you? Let's see if you recognize any of these recent Facebook  messages that jeopardize your security. All of these came from my  Facebook friends in just the past few weeks:
1. Who knows you best? 
The message reads:
Can  you do this? My middle name __________, my age ___, my favorite soda  _______, my birthday ___/___/___, whose the love of my life ______, my  best friend _____, my favorite color ______, my eye color _______, my  hair color ______ my favorite food ________ and my mom's name  __________. Put this as your status and see who knows you best.
How  many of these are the same facts your bank asks to verify your  identity? Put this as your status and everybody -- including all the  people who want to hijack your bank account and credit cards -- will  know you well enough to make a viable attempt.
2. Your  friend [Name here] just answered a question about you!
Was  it possible that an old friend answered a question about me that I  needed to "unlock?" Absolutely. But when you click on the link, the next  screen should give you pause: 21 Questions is requesting permission to  ... (a) access your name, profile picture, gender, networks, user ID,  friends and any other information shared with everyone ... (b) send you  email ... (c) post to your wall ... and ... (d) access your data any  time ... regardless of whether or not you're using their application.
Can  you take that access back -- ever? It sure doesn't look like  it. There's no reference to how you can stop them from future access to  your data in their "terms and conditions." Worse, it appears that to  "unlock" the answer in your friend's post, you need to answer a bunch of  questions about your other friends and violate their privacy too. I  didn't give 21 Questions access to my information, but the roughly 850  people who joined "People Who Hate 21 Questions on Facebook"  apparently have and can give you insight into just how pernicious this  program can be.
3. LOL. Look at the video I found of you!
This  is the most dangerous of all the spam messages and it comes in a  variety of forms, says Clare. It's actually a bid to surreptitiously  install malware on your computer. This malware can track your computer  keystrokes and record your sign-in and password information with all of  your online accounts.
How does it work? When you click on the  link, it says that you need to upgrade your video player to see the  clip. If you hit the "upgrade" button, it opens your computer to the  crooks, who ship in their software. You may be completely unaware of it  until you start seeing strange charges hit your credit cards or bank  account. Up-to-date security software should stop the download. If you  don't have that, watch out.
Better yet, if you really think some  friend is sending you a video clip, double-check with the friend to be  sure before you click on the link. When I messaged my high-school  classmate to ask if she'd really sent this, she was horrified. Her  Facebook account had been hijacked and anyone who clicked through was  likely to have their account hijacked too. That's how this virus spreads  virally.
4. We're stuck!
It started out as an email  scam, but now the "We're stuck in [Europe/Asia/Canada] and need money"  scam has moved to instant messages on Facebook, where it can be more  effective. Most people have learned not to react to the email, but  instant messages help crooks by forcing you to react emotionally -- They're  right there. They need help, now. A friend got one of these  messages last week from the parents of a close friend. Her reaction was  the perfect way to deal with it: She immediately called her friend and  said "Have you talked to your parents lately?" The response: "Yeah.  They're right here."
                                        Facebook has launched a  security system to combat account hijacking that allows crooks to send  messages and posts through your account. You can get updates on what  they're doing at Facebook's security page, where they've also got a  nice little security quiz that's definitely worth taking.
