Scammers take advantage of the latest tragedy to spread malware on Facebook, and it's reportedly affecting one Facebook user per second. A link claims to take you to a video obtained by an Oslo security camera showing the detonation of the car bomb near a Norwegian government building killing at least 10 people. There was no security camera in Oslo that captured the bombing, however the Facebook link says, “[Video] OSLO Security Camera Captures Blast!”. Delete the post and report it to Facebook. It's also obvious that you shouldn't click on the link.
Security firm, Sophos says that clicking on the link will take you to another site with a video player that mimics Facebook. They're asked to take a survey and are presented with an IQ test. Then users are asked to enter their mobile phone number and are charged $2 (Rs. 90 approx) per trivia question, four times a week. Needless to say, users never actually get to watch a video from a security camera from Oslo. Watch out for this scam, and others, of course. Criminals like to take advantage of topical disasters to allure Facebook users to their scams.
