Social engineers routinely target employees or departments that are likely to be less protective of the requested information. For example, the attacker may call the accounts payable department masquerading as a telephone company employee who is trying to resolve a billing problem. The attacker then asks for any known fax or dial-in numbers in order to resolve the problem. The intruder often targets an employee who is unlikely to realize the danger of releasing such information, or who lacks training with respect to company disclosure policy and procedures.
