Sextortion scammers have started to utilize new tactics to bypass spam filters and secure email gateways so that their scam emails are delivered to their intended recipients. Sextortion scams are emails that pretend to be from an attacker who has hacked your PC and installed malware that can monitor what sites you visit and create videos using your webcam. These emails go on to state that they have created a video of you while watching adult web sites and will send the video to all of your contacts unless you pay an extortion demand.
