The Better Business Bureau has a warning out about a scam involving the missing Malaysian airlines flight. Here's how it works. You're on a social media site and a post catches your attention that reads something like this:

"Video Of Plane Found In Bermuda Triangle And Passengers Are Alive!" or "News Flash Missing Plane Has Been Found!"

You then click the link thinking it's a news site but instead you end up on one that asks you to update your video player. Click on that and you could end up  downloading a bunch of malware onto your computer.

Officials also say use caution before opening what your friends send you. Their accounts may have been hacked without them knowing about it. They also say be aware of something called "clickjacking". It's a technique scammers use to try and trick you into clicking on something that you normally wouldn't.
