What is phone phreaking?

The term freaking was coined in the 1970’s, the term combines the words ‘phone’ and ‘freak’ to describe those that exploited or hacked telecommunication networks.


Why do people ‘phreak’?

It is believed people began to phreak as a means of satisfying their curiosity towards phone networks and how they operate. This is said to have been the original motivation of phreakers, not the desire to rack up a hefty phone bill.

Nowadays, phone phreaking is usually motivated by the desire to make ‘free’ phone calls to long-distance, international telephone numbers, without incurring the increased fees. Phone phreaking might also be used to ‘tap’ phone calls, allowing phreakers to monitor conversations.


Is phone phreaking dangerous?

Phone phreaking can result in a large, unexpected telephone bill. Phreakers using your telephone network to make calls that incur increased fees, in this case phone phreaking can be considered very dangerous with regards to your bank account.

However, phone phreaking might have more than just a financial impact on your business. Leaving your business’ telecommunication networks open to phreaking allows for a breach of private and confidential data. This breach can happen as a result of phone freaking with the intention of tapping phonelines, harvesting data about your business and its private operations.
