!SECURITY ALERT:
Social Engineering — “Social Engineering” is a con game that hackers frequently use. It is sometimes referred to as “Operator Deceit.” The success of this con requires gullibility or laxity on the part of the operator or employee, of which the hacker takes full advantage. For example, hackers call an employee, claim to have the wrong extension number, and ask to be transferred back to the operator. To the operator, the call appears to be an internal call. The hacker then asks for an outside line. Often, because operators are not trained about toll fraud, they will connect the hacker to an outside line. Another example of social engineering is when a hacker calls the operator and pretends to be a telephone maintenance repair person. They make statements such as: “This is AT&T testing your lines. Please transfer me to 900 or 9#,” or “I need to verify your DID number range.” An untrained operator may provide the requested transfer or information, giving the hacker more ammunition with which to crack your system.
