Sextortion emails 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. The only text in English is the instructions to “Use google translator”” The scam emails are being sent to English speaking users but with the content written in Russian.”
