The main goal of a sextortion scam is to scare the recipient of the email into making a payment in order to avoid the embarrassment of an alleged video being sent to their friends and family. Email subjects like “RE: Case #48942113 [email protected] You have been warned many times – 07/04/2019 10:57:20″” and state that they have webcam video of you utilizing porn sites. They then threaten to share this video with all of your contacts if you do not send them $660 USD in bitcoins. Enclosed in the spam email will be a link that when clicked on will bring you to a site called cryptonator.com.”
