What type of social engineering involves a sinister user forcefully demanding the immediate transmission of top-secret documents, threatening that failure to comply would sabotage a multimillion-dollar deal and leave their salesperson high and dry?

Intimidation is a social engineering tactic in which the attacker employs bullying tactics or threats to coerce the victim into taking action. Familiarity involves the attacker creating a connection with the victim beforehand or impersonating someone the victim regularly interacts with. Consensus is a strategy where the attacker fabricates fake testimonials to persuade the victim that others have used the software or webpage being offered, making it appear safe. Scarcity is another social engineering technique that involves presenting what the attacker is offering as rare or unavailable elsewhere.
