1. The art and science of cracking the phone network (so as, for example, to make free long-distance calls). 2. By extension, security-cracking in any other context (especially, but not exclusively, on communications networks).
Closely related to hacking, using a computer or other device to trick a phone system. Typically, phreaking is used to make free calls or to have calls charged to a different account. There are many forms of phreaking, be it stealing from the phone company or adding a neat light that flashes when your phone rings. Phreaking is essentially the art of exploiting bugs and glitches in the telco's system. Phreaking is illegal and will not be tolerated on our servers.
Hacking directed at the telephone system (as opposed to the data communications networks) or hacking with a telephone. Using different "boxes" and "tricks" to manipulate the phone companies and their phones, phreakers can gain many things, two of which are knowledge about telephones and how they work, and free local and long-distance phone calls.
This involves illegally breaking into the telephone network to make free long-distance phone calls or to tap phone lines. This term is also used to include the act of breaching the security of any network.
Phreaking is a slang term coined to describe the activity of a subculture of people who study, experiment with, or explore telephone systems, the equipment of telephone companies, and systems connected to public telephone networks. The term "phreak" is a portmanteau of the words "phone" and "freak." It may also refer to the use of various audio frequencies to manipulate a phone system.
