Reports any private (RFC1918) IPv4 addresses found in the various fields of an SSL service's certificate. These will only be reported if the target address itself is not private. Nmap v7.30 or later is required.
Retrieves a target host's time and date from its TLS ServerHello response.
This script repeatedly initiates SSLv3/TLS connections, each time trying a new cipher or compressor while recording whether a host accepts or rejects it. The end result is a list of all the ciphersuites and compressors that a server accepts.
Checks whether the SSL certificate used by a host has a fingerprint that matches an included database of problematic keys.
Check if the Secure Socket Tunneling Protocol is supported. This is accomplished by trying to establish the HTTPS layer which is used to carry SSTP traffic as described in: - http://msdn.microsoft.com/en-us/library/cc247364.aspx
Retrieves the external IP address of a NAT:ed host using the STUN protocol.
Detects whether a host is infected with the Stuxnet worm (http://en.wikipedia.org/wiki/Stuxnet).
Produces a list of IP prefixes for a given routing AS number (ASN).
This script runs in the pre-scanning phase to map IPv4 addresses onto IPv6 networks and add them to the scan queue.
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.
Inserts traceroute hops into the Nmap scanning queue. It only functions if Nmap's
--tracerouteoption is used and the
newtargetsscript argument is given.
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.
This script enumerates information from remote Microsoft Telnet services with NTLM authentication enabled.
Enumerates TFTP (trivial file transfer protocol) filenames by testing for a list of common ones.
Enumerates a TLS server's supported application-layer protocols using the ALPN protocol.
Enumerates a TLS server's supported protocols by using the next protocol negotiation extension.
Connects to a tn3270 'server' and returns the screen.
Lists the geographic locations of each hop in a traceroute and optionally saves the results to a KML file, plottable on Google earth and maps.
Extracts information from Ubiquiti networking devices.
Attempts to extract system information from the UPnP service.
Detects the Ventrilo voice communication server service versions 2.1.2 and above and tries to determine version and configuration information. Some of the older versions (pre 3.0.0) may not have the UDP service that this probe relies on enabled by default.
Extracts information, including file paths, version and database names from a Versant object database.
Queries VMware server (vCenter, ESX, ESXi) SOAP API to extract the version information.
Queries a VNC server for its protocol version and supported security types.
Tries to log into a VNC server and get its desktop name. Uses credentials discovered by vnc-brute, or None authentication types. If
realvnc-auth-bypasswas run and returned VULNERABLE, this script will use that vulnerability to bypass authentication.
Retrieves cluster and store information from the Voldemort distributed key-value store using the Voldemort Native Protocol.
Retrieves some basic information, including protocol version from a Vuze filesharing node.
Detects vulnerabilities and gathers information (such as version numbers and hardware support) from VxWorks Wind DeBug agents.
Detect the T3 RMI protocol and Weblogic version
Attempts to retrieve information about the domain name of the target
Queries the WHOIS services of Regional Internet Registries (RIR) and attempts to retrieve information about the IP Address Assignment which contains the Target IP Address.
Retrieves and displays information from devices supporting the Web Services Dynamic Discovery (WS-Discovery) protocol. It also attempts to locate any published Windows Communication Framework (WCF) web services (.NET 4.0 or later).
Requests an XDMCP (X display manager control protocol) session and lists supported authentication and authorization mechanisms.
Performs XMLRPC Introspection via the system.listMethods method.
Connects to XMPP server (port 5222) and collects server information such as: supported auth mechanisms, compression methods, whether TLS is supported and mandatory, stream management, language, support of In-Band registration, server capabilities. If possible, studies server vendor.
