This module generates a valid wpad.dat file for WPAD mitm

attacks. Usually this module is used in combination with DNS attacks

or the 'NetBIOS Name Service Spoofer' module. Please remember as the
|

server will be running by default on TCP port 80 you will need the
|

required privileges to open that port.
