Wardialing Brief

 

Wardialing consists of using a computer to dial a given set of telephone numbers with a modem. Each phone number that answers with modem handshake tones and is successfully connected to is stored in a log. By searching a range of phone numbers for computers, one can find entry points into unprotected systems and backdoors into seemingly secure systems. This brief paper introduces the concept of wardialing, examines concerns with today’s network setups, and contains a reference of related news reports, security papers, software tools, and Internet resources.
