This post got me thinking about my old hobbies as a high schooler in the late 80s and I remembered war dialing. It was trilling to come home after school and see what my dailer had discovered while I was away. With a few weeks of dialing, I covered all of prefixes in my local exchange. Found a back door into my high school's library (but never could guess or shoulder-surf the password, sadly) and found a terminal server at the local university where I could telnet out without any authentication. I was just now googling around for war dialers and came across this: http://sourceforge.net/projects/iwar/ http://sourceforge.net/projects/iwar/ Looks pretty awesome and supports SIP/IAX2. I may have to give it a shot. Surely there are still some interesting back doors out there.
