Pretexting
This is a method of indirectly putting pressure on targets to get them to divulge some information or perform unusual actions. It involves the construction of an elaborate lie that has been well-researched so as to appear legitimate to the target. This technique has been able to get accountants to release huge amounts of money to imaginary bosses who issue an order for payment into a certain account. It is therefore very easy for a hacker to use this technique to steal login credentials of users, or to get access to some sensitive files. Pretexting can be used to mediate an even bigger social engineering attack that will use the legitimate information to construe another lie. Social engineers that use pretexting have honed the art of impersonating other trusted individuals in society, such as police officers, debt collectors, tax officials, clergy, or investigators.
