I received this email : "I am a hacker who has access to your operating system... I also have full access to your account. I've been watching you for a few months now. The fact is that you were infected with malware through an adult site that you visited... I made a video showing how you satisfy yourself in the left half of the screen, and in the right half you see the video that you watched. With one click of the mouse, I can send this video to all your emails and contacts on social networks. I can also post access to all your e-mail correspondence and messengers that you use. If you want to prevent this, transfer the amount of $500 to my bitcoin address. After receiving the payment, I will delete the video and you will never hear me again. I give you 50 hours (more than 2 days) to pay. I have a notice reading this letter, and the timer will work when you see this letter. .. If I find that you have shared this message with someone else, the video will be immediately distributed.
