Attempts to guess username/password combinations over SMB, storing discovered combinations for use in other scripts. Every attempt will be made to get a valid list of users and to verify each username before actually using them. When a username is discovered, besides being printed, it is also saved in the Nmap registry so other Nmap scripts can use it. That means that if you're going to run smb-brute.nse, you should run other smb scripts you want. This checks passwords in a case-insensitive way, determining case after a password is found, for Windows versions before Vista.

Checks for vulnerabilities:

• MS08-067, a Windows RPC vulnerability
• Conficker, an infection by the Conficker worm
• Unnamed regsvc DoS, a denial-of-service vulnerability I accidentally found in Windows 2000
• SMBv2 exploit (CVE-2009-3103, Microsoft Security Advisory 975497)
• MS06-025, a Windows Ras RPC service vulnerability
• MS07-029, a Windows Dns Server RPC service vulnerability

Attempts to enumerate domains on a system, along with their policies. This generally requires credentials, except against Windows 2000. In addition to the actual domain, the "Builtin" domain is generally displayed. Windows returns this in the list of domains, but its policies don't appear to be used anywhere.

Obtains a list of groups from the remote Windows system, as well as a list of the group's users. This works similarly to enum.exe with the /G switch.

Pulls a list of processes from the remote server over SMB. This will determine all running processes, their process IDs, and their parent processes. It is done by querying the remote registry service, which is disabled by default on Vista; on all other Windows versions, it requires Administrator privileges.

Enumerates the users logged into a system either locally or through an SMB share. The local users can be logged on either physically on the machine, or through a terminal services session. Connections to a SMB share are, for example, people connected to fileshares or making RPC calls. Nmap's connection will also show up, and is generally identified by the one that connected "0 seconds ago".

Attempts to list shares using the srvsvc.NetShareEnumAll MSRPC function and retrieve more information about them using srvsvc.NetShareGetInfo. If access to those functions is denied, a list of common share names are checked.

Attempts to enumerate the users on a remote Windows system, with as much information as possible, through two different techniques (both over MSRPC, which uses port 445 or 139; see smb.lua). The goal of this script is to discover all user accounts that exist on a remote system. This can be helpful for administration, by seeing who has an account on a server, or for penetration testing or network footprinting, by determining which accounts exist on a system.

Exhausts a remote SMB server's connection limit by by opening as many connections as we can. Most implementations of SMB have a hard global limit of 11 connections for user accounts and 10 connections for anonymous. Once that limit is reached, further connections are denied. This script exploits that limit by taking up all the connections and holding them.

Attempts to print text on a shared printer by calling Print Spooler Service RPC functions.

Implements remote process execution similar to the Sysinternals' psexec tool, allowing a user to run a series of programs on a remote machine and read the output. This is great for gathering information about servers, running the same tool on a range of system, or even installing a backdoor on a collection of computers.

Attempts to grab the server's statistics over SMB and MSRPC, which uses TCP ports 445 or 139.

Pulls back information about the remote system from the registry. Getting all of the information requires an administrative account, although a user account will still get a lot of it. Guest probably won't get any, nor will anonymous. This goes for all operating systems, including Windows 2000.

Tests whether target machines are vulnerable to ms10-061 Printer Spooler impersonation vulnerability.

Performs brute force password auditing against SMTP servers using either LOGIN, PLAIN, CRAM-MD5, DIGEST-MD5 or NTLM authentication.
