Phreaking is the art and science of cracking the phone network so as to make free long-distance calls. The first real form of electronic hacking began with the telephone system. But around 1980?s the changes in the phone network made old-style technical ingenuity less effective as a way of hacking it, so phreaking came to depend more on overtly criminal acts such as stealing phone-card numbers. It is very closely related to Internet security, as communication networks are the backbone of Internet. Moreover the integration of Data and Voice networks makes it even more vulnerable. Even though we don?t hear any ?blue box? stories these days, Phreaking has also become more technologically advanced.
