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.
