blackmail

Blackmail is an act of coercion using the threat of revealing or publicizing either substantially true or false information about a person or people unless certain demands are met. It is often damaging information, and it may be revealed to family members or associates rather than to the general public. These acts can also involve using threats of physical, mental or emotional harm, or of criminal prosecution, against the victim or someone close to the victim. It is normally carried out for personal gain, most commonly of position, money, or property.
