ETHICAL HACKING Questions and Answers

What is a hacking loop?

A loop is two phone numbers connected together by the phone company for testing purposes. A loop has a high end and a low end. If you dial the high end, you will hear nothing. Not even a ring. If you dial the low end, you will hear an annoying 1,000hz tone for several seconds. If you connect to the high end and someone dials the low
end, you can speak to each other.
