<p> Sun Microsystems use to say, “The network is the computer.” This talk will focus on that “other” computer. The neglected computer. The PSTN (Public Switched Telephone Network) “computer.” Throwing VoIP into the mix, it’s never been easier to “map” that neglected “computer.” This talk will discuss how to map the “Human Network” as well as new techniques in automated PSTN network scanning including more X.25 network goodies. This is the second part of “Hacking International Networks using VoIP” from The Last HOPE. </p>
