Obtains a list of groups from the remote Windows system, as well as a list of the group's users. This works similarly to
Pulls a list of processes from the remote server over SMB. This will determine all running processes, their process IDs, and their parent processes.

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".

srvsvc.NetShareEnumAllMSRPC 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 retrieve useful information about files shared on SMB volumes. The output is intended to resemble the output of the UNIX
Queries information managed by the Windows Master Browser.
Attempts to determine the operating system, computer name, domain, workgroup, and current time over the SMB protocol (ports 445 or 139). This is done by starting a session with the anonymous account (or with a proper user account, if one is given; it likely doesn't make a difference); in response to a session starting, the server will send back all this information.
Attempts to print text on a shared printer by calling Print Spooler Service RPC functions.
Attempts to list the supported protocols and dialects of a SMB server.
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.

Returns information about the SMB security level determined by SMB.
Attempts to grab the server's statistics over SMB and MSRPC, which uses TCP ports 445 or 139.

This script takes a table of paths to private keys, passphrases, and usernames and checks each pair to see if the target ssh server accepts them for publickey authentication.

Sends an ICMPv6 echo request packet to the all-nodes link-local multicast address (
ff02::1) to discover responsive hosts on a LAN without needing to individually ping each IPv6 address.
Sends an ICMPv6 packet with an invalid extension header to the all-nodes link-local multicast address (
ff02::1) to discover (some) available hosts on the LAN. This works because some hosts will respond to this probe with an ICMPv6 Parameter Problem packet.
Attempts to discover available IPv6 hosts on the LAN by sending an MLD (multicast listener discovery) query to the link-local multicast address (ff02::1) and listening for any responses. The query's maximum response delay set to 1 to provoke hosts to respond immediately rather than waiting for other responses from their multicast group.
Performs IPv6 host discovery by triggering stateless address auto-configuration (SLAAC).
Adds IPv6 addresses to the scan queue using a wordlist of hexadecimal "words" that form addresses in a given subnet.
Sniffs the local network for a configurable amount of time (10 seconds by default) and prints discovered addresses. If the
newtargetsscript argument is set, discovered addresses are added to the scan queue.

--tracerouteoption is used and the
newtargetsscript argument is given.
Loads addresses from an Nmap XML output file for scanning.

Performs brute-force password auditing against telnet servers.
Determines whether the encryption option is supported on a remote telnet server. Some systems (including FreeBSD and the krb5 telnetd available in many Linux distributions) implement this option incorrectly, leading to a remote root vulnerability. This script currently only tests whether encryption is supported, not for that particular vulnerability.

Extracts information from Ubiquiti networking devices.
Runs unit tests on all NSE libraries.
Compares the detected service on a port against the expected service for that port number (e.g. ssh on 22, http on 80) and reports deviations. The script requires that a version scan has been run in order to be able to discover what service is actually running on each port.
Attempts to extract system information from the UPnP service.
Gets system information from an Idera Uptime Infrastructure Monitor agent.
Sniffs an interface for HTTP traffic and dumps any URLs, and their originating IP address. Script output differs from other script as URLs are written to stdout directly. There is also an option to log the results to file.
