As you may have noticed, I sent this email from your email account (if you didn't see, check the from email id). In other words, I have full access to your email account.
I infected you with a malware a few months back when you visited an adult site, and since then, I have been observing your actions. The malware gave me full access and control over your system, meaning, I can see everything on your screen, turn on your camera or microphone, and you won't even notice about it. I also have access to all your contacts.
I made a video showing both you (through your webcam) and the video you were watching (on the screen) while satisfying yourself. With one click, I can send this video to all your contacts (email, social network, and messengers you use).
You can prevent me from doing this. To stop me, transfer $980 to my bitcoin address.
You have 48 hours to pay. Since I already have access to your system, I now know that you have read this email, so your countdown has begun.
