policeman. They then threaten an individual, telling them that they will be in trouble if

preparation for these attacks, hackers make themselves familiar to their victims; they
come around a lot bringing with them boxes of chocolates and eventually they become
trusted. At that point, they can begin working their way inside a company, for example,
gaining access to areas of the company that they should not be able to access. This is
effective as they become part of the furniture and nobody questions their actions.
Principles, Urgency (social engineering) - correct answer An example of an urgency
attack is someone arriving at a reception desk and demanding access quickly. They
could target a new receptionist, who may get flustered and let them in.
