NBSpyder.exe

NBpyder, or NetBios Spyder is a suite of NT batch files that take advantage of Windoze netbios connections to glean information about a corporation's network. NBSpyder works by first enumerating domains that the computer can see over a LAN. It then proceeds to get a comprehensive list of machines for that domain, their domain controllers, local administrators and domain admins, and a comprehensive list of IP addresses for that domain. It then attempts to gain administrative access on the domain controllers by semi-intelligent brute force password guessing , and, if successful, goes ahead and downloads the domain user and policy list.
