Is an email claiming to have a video of me visiting adult websites real?

Mass-sextortion emails claim the sender installed malware on your device while you visited an adult website, recorded your screen and webcam simultaneously, and will send the footage to your contacts unless you pay in cryptocurrency. To make the threat seem credible, some emails include an old password from a data breach or the first few digits of your phone number — details obtained from publicly available breach databases. In the vast majority of cases, no such recording exists. These are bluff campaigns sent to millions of people at once. The payment request is the only goal. Replying, paying, or engaging escalates contact. If the email contains a password you still use, change it immediately and enable two-factor authentication on affected accounts.
