Explanation:
Person-to-Person social engineering works on the personal level. It can be classified as
follows:
Impersonation: In the impersonation social engineering attack, an attacker pretends to be someone
else, for example, the employee’s
friend, a repairman, or a delivery person.
In Person Attack: In this attack, the attacker just visits the organization and collects information. To
accomplish such an attack, the
attacker can call a victim on the phone, or might simply walk into an office and pretend to be a client
or a new worker.
Important User Posing: In this attack, the attacker pretends to be an important member of the
organization. This attack works
because there is a common belief that it is not good to question authority.
Third-Party Authorization: In this attack, the attacker tries to make the victim believe that he has the
approval of a third party. This
works because people believe that most people are good and they are being truthful about what
they are saying.
