Blackmail

Blackmail is a social engineering attack in which an adversary threatens to expose damaging information about a victim unless they receive payment, access credentials, or other valuable concessions. Unlike most social engineering tactics, blackmail is overt — the victim knows they are being coerced.

About this video

Blackmail is a coercive attack in which an adversary leverages compromising information against a target, threatening to expose it unless specific demands are met. The damaging material can range from evidence of a personal affair or financial misconduct to proof of corporate theft or other serious wrongdoing. The attacker's leverage depends entirely on the victim's desire to keep that information hidden — from an employer, business partners, or the public at large. Demands are not limited to monetary payment and can include access credentials, sensitive internal data, proprietary technical designs, or other assets that serve the attacker's broader objectives, including corporate espionage. This sets blackmail apart from most social engineering attacks, which rely on deception and misdirection to manipulate targets without their awareness. Blackmail is inherently overt: the victim understands exactly what is happening but calculates that the cost of compliance is lower than the cost of exposure — whether that means losing a job, a reputation, or facing legal consequences. Because it constitutes extortion, blackmail is illegal in most jurisdictions and can result in criminal prosecution for the attacker.

What Blackmail Is

Blackmail is when the adversary has some sort of information on a victim and will release it unless the victim does something for them. The blackmailer is not revealing damaging information in exchange for some sort of payment.

There are two sides to this. There's what the blackmailer has on hand — maybe it is pictures of them having an affair with somebody else, or maybe it's some sort of evidence that they're embezzling money or stealing other products from the company, or maybe doing something else terrible to the company. They have this proof that the victim is doing something that is going to get them in trouble, and they will release this information unless they get some sort of payment. It could be in the form of cash, or it could be in the form of access credentials into the system, or maybe getting some sort of information on the company. Maybe it's some sort of technical designs and there's some espionage going on. It could be many different things here. Blackmail is the idea that this information is going to be released unless you do this for me.

Overt Rather Than Covert

Where most of the social engineering is a little more covert, where they're trying to mislead the other person, blackmail is more overt: the victim realizes that they are doing something wrong. It's just that the fear that this information gets leaked out to the rest of the world, or to the business, or to whoever — the fear of that getting leaked out is more than the fear of getting caught for whatever they're handing over. Or maybe it's more fear of losing that money, or more fear of losing their job because they are giving away access into the company's mainframe system, or whatever the case may be.

This is a little more of an overt type of an attack. Blackmail usually is illegal and can get you thrown into jail.
