This is generally known either as a “webcam blackmail”, “sextortion scam” or a “scam email”. You may or may not have come across it but these types of mails are normally diverted into your junk folder. Within the junk folder, these mails are the ones that stand out compared to the rest. The typical spam mails that tries to lure users into clicking their link with too-good-to-be-true offers or lewd titles would end up being ignored by an average person. The blackmail scams on the other hand, are structured to be intrusive in nature. Most blackmails share the following similar feature on their subject line :

• A partial or fully correct password that the target victim has used some time ago.
• Gained access into the victims device and used it to film the victim via webcam.
• Gathered data on the victims adult site habits and is ready to send them to their family members/friends.

These features can sometimes get personal with the user and they will, in favor of the attacker, become intimidated and even give in to their demands. Demands such as payments in Bitcoin(BTC) through a BTC address will be included in the end of the mail and it will not be possible to track it back to the sender.
