The latest sextortion campaign is the latest in a string of cybercrime targeting victims. The crooks claim to have taken pictures of you watching porn, synchronised with a recording they made at the same time via your webcam. They then threaten to tell the world (or at least your colleagues, friends and family) all about it. Unless you send them money right away, usually in the form of a Bitcoin, and usually within 48 hours. Its all a pack of lies, of course the crooks blast out millions of these messages in the hope that the contents will be close enough to the truth that at least some victims will pay up.”]
