Facebook users post status messages claiming U.S. has attacked Iran and Saudi Arabia in a move heralding the beginning of World War 3. If you visit the link mentioned in the status update, you are taken to a fake CNN news webpage which claims to contain video footage of conflict. Clicking on the video thumbnail prompts the webpage to ask you to install an update to Adobe Flash. Of course, its not a real Flash update, but malware instead. Remember, you should only ever download a Flash update from the genuine Adobe website.”]
