- "extract (a modulating signal) from its carrier."
Episode 2: "The Wardialer" - Popular in the 1980s and 1990s, "wardialing"
was a popular method hackers used to find computer system to attack. Prior to the
movie "WarGames", it was known
as "demon dialing". Whatever you called it, there was much more to "wardialing" than
just dialing a bunch of telephone phone numbers. There was a complete methodology hackers
used to avoid punishment from 'Ma Bell' (The phone company) and law enforcement. There
was also more to wardialing than just looking for modem carriers. Wardialing was used
to identify PBX (Private Branch eXchanges), telco "test" equipment,
unprotected voice mail systems, fax machines, HVAC/temperature control systems, elevators,
radio towers and much. By the early 2000's, the art of wardialing was almost dead. Then
hackers started to use VoIP (Voice over IP) to take wardialing in a completely new direction.
In this episode of Demodulate, we discuss the old and the new school of wardialing.

used KissFFT rather than a modem to detect. This is
another demo of iWar. This give you
an idea of the speed a prefix could be scanned. Unfortunately, the this code was lost :(
