An attacker engages in pretexting behavior, assuming the role of a
						delivery person, to solicit information from target persons, or manipulate
						the target into performing an action that serves the attacker's interests.
						Impersonating a delivery person is an effective attack and an easy attack
						since not much acting is involved. Usually the hardest part is looking the
						part and having all of the proper credentials, papers and "deliveries" in
						order to be able to pull it off.
