Nmap 7 Released
November 19, 2015—The Nmap Project is pleased to announce the
immediate, free availability of the Nmap Security Scanner version 7.00 from
https://nmap.org/. It is the product of three
and a half years of work, nearly 3200 code commits, and more than a dozen point
releases since the big Nmap 6 release in May
2012. Nmap turned 18 years old in September this year and celebrates its
birthday with 171 new NSE scripts, expanded IPv6 support, world-class SSL/TLS
analysis, and more user-requested features than ever.
We recommend that all current users upgrade.

Nmap (“Network Mapper”) is a free and open source
(license) utility for network
discovery and security auditing. Many systems and network administrators also
find it useful for network inventory, managing service upgrade schedules,
monitoring host or service uptime, and many other tasks. Nmap uses raw IP
packets in novel ways to determine what hosts are available on the network, what
services (application name and version) those hosts are offering, what operating
systems (and OS versions) they are running, what type of packet
filters/firewalls are in use, and dozens of other characteristics. It was
designed to rapidly scan large networks, but works fine against single hosts.
Nmap runs on all major computer operating systems, and official binary packages
are available for Linux, Windows, and Mac OS X. In addition to the classic
command-line Nmap executable, the Nmap suite includes an advanced GUI and
results viewer (Zenmap), a flexible data
transfer, redirection, and debugging tool
(Ncat), a utility for comparing scan
results (Ndiff), and a packet generation
and response analysis tool (Nping).
Nmap was named “Security Product of the Year” by Linux Journal,
Info World, LinuxQuestions.Org, and Codetalker Digest. It was even featured in
nineteen movies and TV series, including
The Matrix Reloaded,
The Bourne Ultimatum.
Girl with the Dragon Tattoo,
and Die Hard 4. Nmap was
released to the public in 1997 and has earned the trust of millions of
As free software, we don't have any sort of advertising budget. So please spread the word that Nmap 7 is now available!
Before we get into the detailed changes, here
are the top 7 improvements in Nmap 7:
- 1. Major Nmap Scripting Engine (NSE) Expansion
As the Nmap core has matured, more and more new functionality
is developed as part of our NSE subsystem instead. In fact, we've
added 171 new scripts and 20 libraries since Nmap 6. Examples include
And NSE is now powerful enough that scripts can take on core functions such
as host discovery (dns-ip6-arpa-scan),
version scanning (ike-version,
etc.), and RPC grinding (rpc-grind).
There's even a proposal
port scanning in NSE. [More Details]
- 2. Mature IPv6 support
IPv6 scanning improvements were a big item in the Nmap 6 release, but
Nmap 7 outdoes them all with full IPv6 support for CIDR-style
address ranges, Idle Scan, parallel reverse-DNS, and more NSE script coverage. [More Details]
- 3. Infrastructure Upgrades
We may be an 18-year-old project, but that doesn't mean we'll stick with old, crumbling infrastructure! The Nmap Project continues to adopt the latest technologies to enhance the development process and serve a growing user base. For example, we converted all of Nmap.Org to SSL to reduce the risk of trojan binaries and reduce snooping in general. We've also been using the Git version control system as a larger part of our workflow and have an official Github mirror of the Nmap Subversion source repository and we encourage code submissions to be made as Github pull requests. We also created an official bug tracker which is also hosted on Github. Tracking bugs and enhancement requests this way has already reduced the number which fall through the cracks. [More Details]
- 4. Faster Scans
Nmap has continually pushed the speed boundaries of synchronous network
scanning for 18 years, and this release is no exception. New Nsock engines
give a performance boost to Windows and BSD systems, target reordering
prevents a nasty edge case on multihomed systems, and NSE tweaks lead to much
faster -sV scans. [More Details]
- 5. SSL/TLS scanning solution of choice
Transport Layer Security (TLS) and its predecessor, SSL, are the
security underpinning of the web, so when big vulnerabilities like Heartbleed,
POODLE, and FREAK come calling, Nmap answers with vulnerability detection NSE
scripts. The ssl-enum-ciphers
script has been entirely revamped to perform fast analysis of TLS deployment
problems, and version scanning probes have been tweaked to quickly detect the
newest TLS handshake versions. [More Details]
- 6. Ncat Enhanced
We are excited and proud to announce that Ncat has been adopted by the
Red Hat/Fedora family of distributions as the default package to provide the
"netcat" and "nc" commands! This cooperation has resulted in a lot of squashed
bugs and enhanced compatibility with Netcat's options. Also very exciting is
the addition of an embedded Lua interpreter for creating simple,
cross-platform daemons and traffic filters.
- 7. Extreme Portability
Nmap is proudly cross-platform and runs on all sorts of esoteric and
archaic systems. But our binary distributions have to be kept up-to-date with
the latest popular operating systems. Nmap 7 runs cleanly on Windows 10 all
the way back to Windows Vista. By popular request, we even built it to run on
Windows XP, though we suggest those users upgrade their systems. Mac OS X is
supported from 10.8 Mountain Lion through 10.11 El Capitan. Plus, we updated
support for Solaris and AIX. And Linux users—you have it easy.

Nmap 7 provides a wealth of information about remote
systems, as shown in this sample scan against a machine we maintain for
scan testing purposes (scanme.nmap.org).
Here is an example using Zenmap on Windows 8.1 against a
couple of production web servers (Nmap.org
Perhaps the most visually appealing aspect of Zenmap
is its network topology
mapper. Here it is being used to interactively explore the routes
between a source machine and a handful of interesting web sites, using the
The Nmap Changelog
describes more than 330 significant improvements since our last major
(6.00 in May 2012).
Here are the highlights:
The Nmap Scripting Engine (NSE)
is one of Nmap's most powerful and flexible features. It
allows users to write (and share) simple Lua
scripts to automate a wide variety of networking tasks. Those scripts are then
executed in parallel with the speed and efficiency you expect from Nmap. The
low learning curve and powerful networking libraries of NSE make it ideal for
rapid development of security scanning and service probing scripts.
Script count has jumped from 348 to 515 scripts! That is 171 new scripts, minus four deletions. Of these, 109
will run by default when you use -sC, and another 35 will run with -sV for
version detection. The list of new scripts is so long that we can't even include the summaries here, but each script is linked to it's own page on the NSE Documentation Portal for full details:
NSE became the tool of choice for rapid vulnerability scanning with the
advent of celebrity vulnerabilities in 2014. NSE scripts have you covered for
Misfortune Cookie (http-vuln-misfortune-cookie),
and even Slowloris (http-slowloris-check).
Of course if you're also worried about less-celebrated vulnerabilities, the
other 41 new "vuln"-category scripts
should keep you busy.
NSE joins the rest of Nmap in being able to output parseable XML. Instead of
just a text blob in
output, scripts can now return
information that can be quickly extracted with an XML parser. All new
scripts produce structured output, most older scripts have been converted, and
any script using the vulns
library is automatically upgraded.
The venerable RPC grinder which used to run with -sV is now an NSE
This allowed us to cull a bunch of old C code in favor of more maintainable Lua,
as well as make a noticeable improvement in scanning speed, all while using a
fifth of the number of code lines.
HTTP and web scanning continued to dominate our NSE development. Over a
third (57) of our new scripts were HTTP-related. Exceptionally exciting is the
addition of NTLM authentication to the http library, which means http-brute can
bruteforce Windows passwords, too. Script highlights include:
Oops, there was a vulnerability in one of our NSE scripts. If you ran
the (fortunately non-default)
script with the (fortunately also non-default) domino-enum-passwords.idpath
parameter against a malicious server, it could cause an arbitrarily named file
to to be written to the client system. Thanks to Trustwave researcher Piotr
Duszynski for discovering and reporting the problem. We've fixed that script,
and also updated several other scripts to use a new stdnse.filename_escape
function for extra safety. This broke our record of never having a vulnerability
in the 16 years that Nmap has existed, but that's still a fairly good
NSE libraries allow scripts to share code. In addition to the usual set
of protocol helpers, some interesting additions include the LPeg parsing
expression grammar library, a "ls" library for formatting directory listings,
the "slaxml" XML parser, a pure-Lua Unicode library, and a unittest library
currently used by 6 other libraries.
Mature IPv6 Support
It came as no surprise when ARIN ran out of IPv4 addresses this year, and
Nmap was already riding the wave to full IPv6 deployment. Nmap has supported
IPv6 in some way since 2002, but improvements keep coming:
Idle scan is now supported with IPv6.
IPv6 packets don't usually come with fragment identifiers like IPv4 packets do,
so new techniques had to be developed to make idle scan possible. The
implementation is by Mathias Morbitzer, who made it the subject of his master's
Unicast CIDR-style IPv6 range scanning is now supported, so
you can specify targets such as "en.wikipedia.org/120". Obviously it will take
ages if you specify a huge space. For example, a /64 contains
In addition to ensuring IPv6 support in the majority of NSE
scripts, Nmap 7 adds several IPv6-specific scripts for advanced host
discovery and even denial-of-service:
performs a quick reverse-DNS lookup of an IPv6 network using a technique which
analyzes DNS server response codes to dramatically reduce the number of queries
needed to enumerate large networks.
preys on the tendency of human network operators to use the enormous IPv6
address space and the hexadecimal alphabet to assign addresses that form words
like "dead:beef". The wordlist is configurable, and the results are
similarly searches for manually configured addresses that correspond to a
smaller range of IPv4 addresses that may be assigned to the same network.
generates a flood of Router Advertisements (RA) with random source MAC
addresses and IPv6 prefixes. Computers, which have stateless autoconfiguration
enabled by default (every major OS), will start to compute IPv6 suffix and
update their routing table to reflect the accepted announcement. This will cause
100% CPU usage on Windows and platforms, preventing to process other application
Nmap's parallel reverse-DNS resolver now handles IPv6
addresses. GSoC 2015 student Gioacchino Mazzurco rewrote the old C-style DNS
code in beautiful C++ and a test suite, then fuzzed the living daylights out of
it with afl. In addition to being
very safe, this should result in faster -6 scans.
IPv6 OS fingerprinting is improved, thanks to the efforts
of Mathias Morbitzer and Alexandru Geana. Building on Mathias's research into
new IPv6 OS fingerprinting methods, Alexandru spent the spring and summer of
2015 testing and adding features to our machine learning OS classifier. Using
IPv6 guessed initial Hop Limit (analogous to IPv4's TTL) and the ratio of TCP
initial window size to Maximum Segment Size (MSS), the classifier now matches
with more confidence than ever. He also completed an extension of the
classifier's training process to impute missing values from dropped or filtered
packets, which lets Nmap make better guesses when network conditions are
Nmap's advanced traceroute is no longer limited to just
using ICMP and TCP for tracing IPv6 hosts. The IPv6 --traceroute option is now
equivalent to the IPv4 version and capable of using UDP, SCTP, and IPProto (Next
SSL/TLS scanning par excellence
SSL 3 deprecation, SHA-1 certificate deprecation, Heartbleed, CCS injection,
POODLE, LOGJAM, FREAK, and RC4 deprecation—Secure Sockets Layer (SSL) and its
successor, Transport Layer Security (TLS), have received a lot of attention in
the past few years for security problems, and Nmap has emerged as the gold
standard scanning tool for these issues.
One of our most popular NSE scripts is ssl-enum-ciphers,
which enumerates SSL/TLS protocol versions (SSL 3 deprecation!) and ciphersuites
(RC4 deprecation and weak export ciphers!). It has been enhanced beyond the old
behavior of simply reporting "weak" or "strong" for each ciphersuite—it
now scores each handshake using guidance from Qualys SSL Labs and taking into
account server certificate strength, Diffie-Hellman parameter size, and
encryption bit strength. It can safely scan the most finicky of SSL servers,
safely negotiating long handshake intolerance issues and fragmented TLS
messages. And it can run independently of version scan, since it is now capable
of detecting TLS on unusual ports on its own.
Detection of SSL and TLS by -sV
has been boosted by
including more popular TLS ports in the default lists and adding a new TLS-only
service probe. Also, NSE scripts can now do TLS checks against LDAP, IMAP, and
POP3 services which support STARTTLS (FTP, SMTP, and XMPP were already
At the core of our TLS NSE scripts is the new tls library, which enables
quick development of robust scripts for checking vulnerabilities
or reporting configurations
Zenmap graphical front-end and results viewer
Zenmap is our cross-platform (Linux,
Windows, Mac OS X, etc.) Nmap GUI and results viewer. It aims to provide
advanced features for experienced Nmap users while also making Nmap easier for
beginners to use. Frequently used scans can be saved as profiles to make them
easy to run repeatedly. A command creator allows interactive creation of Nmap
command lines. Scan results can be saved and viewed later, or even compared with
one another to see how they differ. Our
network topology viewer
allows for interactive exploration of a network scanned with Nmap. Zenmap is now
a mature tool, but it still got several enhancements since 6.00:
Zenmap features a full
translation capability for all menus, labels, buttons, and messages.
Translations are available for 11 languages, including new Italian, Japanese,
Polish, Chinese, and Hindi translations. The German and French translations were
Support for large scans has drastically improved. We solved a CPU usage bug
in opening large files and prevented the most common cause of out-of-memory
problems by dropping the scrolling output window if it becomes a problem. Don't
worry! The output is still saved to disk. Additionally, scans which have a lot
of anonymous (unresponsive) traceroute hops will take up less space on the
Topology page, since Zenmap will now assume hops at the same distance are the
Zenmap's display can filter hosts based on OS, ports, hostnames, and other
criteria. Since 6.00 we also added negative matching, so you can exclude Windows
systems for example with "os:!windows".
Another sign of a maturing codebase, we've enabled unittest discovery in
Zenmap, so running "make check" will run most of the existing Zenmap tests.
Watch for more improvements in this area in upcoming versions!
Ncat is a feature-packed networking
utility which reads and writes data across networks from the command line. Ncat
was written for the Nmap Project as a much-improved reimplementation of the
venerable Netcat. It uses both
TCP and UDP for communication and is designed to be a reliable back-end tool to
instantly provide network connectivity to other applications and users. Ncat
will not only work with IPv4 and IPv6 but provides the user with a virtually
limitless number of potential uses.
We are excited and proud to announce that Ncat has been adopted by the Red
Hat/Fedora family of distributions as the default package to provide the
"netcat" and "nc" commands! This cooperation has resulted in a lot of squashed
bugs and enhanced compatibility with Netcat's options.
Some of the most exciting changes in Ncat 7 are:
Ncat now features an embedded Lua interpreter! Similar to the Nmap
Scripting Engine, the "--lua-exec" option makes it easy to write simple traffic
filters and daemons in easy-to-learn Lua. A
collection of example scripts, including a simple HTTP server, is included with
the Ncat source.
Ncat now supports Unix domain sockets (named pipes) on systems where
those sockets are available. This is another Netcat compatibility enhancement,
and it makes testing of Unix local services possible with Ncat.
Ncat's proxy support was extended to support SOCKS5 with
More compatibility corrections resulted in correct handling of EOF on all
sockets, whether running as a client or as a server. The new --no-shutdown
option keeps Ncat up and receiving network input after stdin is closed, just
like traditional netcat's -d option.
Keeping the Nmap project vibrant and productive (for developers and users)
requires constant investment in our development. Improvements to Nmap's
development and support infrastructure since Nmap 6 include:
The Nmap.org web site is now 100%
HTTPS. This gives our users much-needed protection when downloading Nmap
source and binary releases or submitting new service and OS fingerprints.
Also, the GNU Mailman subscription pages for the
mailing lists are hosted on Nmap.org and HTTPS-protected, so your subscription
settings are safe, too.
The Nmap Project has fully embraced
Github Issues as its bug
tracking solution. The Nmap-Dev mailing list is still going strong for
discussion of Nmap development issues, but for user-submitted bug reports and
enhancement requests, Github is the place to be. We also encourage code
submissions to be made as Github pull requests. Even though the Github repo is
still a read-only mirror of our authoritative
Github offers a great code review and discussion interface, as well as
integrated code-quality-checking tools. As a convenience, issues.nmap.org is a redirector for issue
On the subject of code quality, Nmap now integrates with Travis CI for
continuous integration testing. If the build breaks, Nmap developers are
notified immediately. Code contributions made as Github pull requests are
automatically checked for build breakage, too. This is made possible by a
concerted effort to enable "make check" to actually check and test Nmap code.
So far, "make check" enables:
- Ncat test suite
- Nsock test suite
- Zenmap auto-discovered unit tests
- NSE tests through the
- Ndiff tests
- Nmap's reverse-DNS engine test suite
Nmap's changelog page is
now displayed in linked and cross-referenced HTML, instead of as a simple dump
of the CHANGELOG text file. URLs, issue numbers, script names, and NSE
library names are all linked to the appropriate pages.
SecWiki.org continues to be used by
the Nmap development team for documentation and collaboration on long-term
projects. Some popular pages are Nmap Code Standards, Nmap on Android, NSE Script Ideas, and the Nmap FAQ pages.
IPv4 Operating System Detection
Thanks to fingerprint submissions from thousands of Nmap users around the
world, our remote operating system
detection system grew from 3572 signatures in Nmap 6 to 4985 now. These
include the latest versions of Windows, Linux, and Mac OS X as well as more
specialized entries such as PLCs, lightbulbs, televisions, mainframes, and much
more. Some of the newest fingerprints are for Apple iOS 9, Android 5.1, OpenBSD
5.7, FreeBSD 11.0, and a ton of new WAPs, switches, printers, and other
In addition to more than 1400 new fingerprints, we made several important
performance improvements and bug fixes to the system. Most notably, if version
detection determines a port to be "tcpwrapped," OS detection will prefer to use
a different port for probing, since there's a good chance this is the result of
a firewall interfering with TCP connections on that port.
The days when we could assume what was running on an open port based on the
port number are long gone. These days, folks commonly run services on the
"wrong" port numbers in order to defeat filtering policies, hide traffic, or
work around various networking problems. Fortunately, Nmap's version detection system is able to
interrogate the service listening on the open port and tell you the service
running as well as (in many cases) the application name and version number.
Nmap 6 had an impressive 8165 signatures matching 862 protocols, but Nmap 7
improves that to a whopping 10299 signatures for 1091 protocols!
Additionally, Nmap 7 has 23 more service probes to pull information from
remote services and more than double the number of softmatch lines (103), which
help short-circuit the probing process to send the most-likely probes for the
In Nmap's 18-year history, performance has always been a top priority.
Whether scanning one target or 20 million, users want scans to run as fast as
possible without sacrificing accuracy. Improvements since Nmap 6 include:
For scans of targets that use different routes or interfaces, Nmap may
now partially rearrange its target list for more efficient host groups.
Previously, a single target with a different interface, or with an IP address
the same as a that of a target already in the group, would cause the group to
be broken off at whatever size it was. Now, we buffer a small number of such
targets, and keep looking through the input for more targets to fill out the
Timeouts for many NSE scripts were reduced from tens of seconds to use
a scaled timeout based on Nmap's portscan-phase timing determinations. A
simple library function,
makes it easy for new script authors to do the same.
Version scan is quicker now because of 56 more softmatch lines that
prevent Nmap from sending irrelevant probes to certain services. Also, NSE
scripts in the
now obey the version intensity setting, so using an option like
--version-light will prevent nearly all of these heavy-duty version probing
scripts from running (unless you choose them by name).
The old RPC Grinder, which used the original pos_scan engine from 1998,
has been replaced by a much faster NSE script implementation. Scan times for
version scanning (-sV) ought to improve greatly.
New poll and kqueue Nsock engines allow for increased socket
performance in Nsock-based scan phases (NSE and version scanning) on Windows,
OS X, and BSD-derived systems that previously had to use the old select-based
engine. Linux has had an epoll engine since Nmap 6.00.
Even More Improvements
In addition to the pages of changes listed above, we made many improvements
which defy simple categorization:
The oft-requested --exclude-ports option has now been
implemented! Easily avoid scanning off-limits or troublesome ports, without
constructing complicated port ranges to avoid them. Safely integrates with -p,
-F, and --top-ports.
Nsock (and by extension Nmap's -sV and NSE) now supports connecting
through chained proxies. Nmap adds the --proxies option to
specify this proxy chain. While port scanning is not yet included, GSoC
student and mentor Jacek Wielemborek has done groundbreaking work towards
implementing TCP Connect scan in Nsock, so stay tuned!
Instead of simply appending random data to Nmap scan packets with
--data-length, try sending a message with the --data-string
or --data options. Safely attribute your research or taunt
your foes—it's up to you.
Though in most cases ARP ping is the stealthiest, fastest, and most
reliable host discovery method, you can now force the usual layer-3 discovery
probes with the --disable-arp-ping option. This is useful in
networks using proxy ARP, which make all addresses appear to be up using ARP
scan. The previously recommended workaround for this situation, --send-ip,
didn't work on Windows it is still missing raw socket support.
For raw packet scans (i.e. not -sT), Nmap now reports the TTL of
recieved packets in the Normal output if the --reason option is used. This was
previously only available in the XML output, but is useful for detecting
interfering firewalls in some cases. Additionally, --reason is enabled at
verbosity 2 and higher.
Fixed a bug which caused Nmap to be unable to have any runtime
interaction when called from sudo or from a shell script on Linux. This was
especially appreciated on Debian-based systems where Nmap is usually invoked
The beloved Nmap ASCII Dragon configure art now shares its spot with
two other ASCII art pieces. Which one you get when you run ./configure is
randomly chosen. Immediately below the art is a summary of what configure
options were chosen, including a warning if OpenSSL could not be found and you
didn't explicitly disable it.
Nping now checks for a matching
ICMP ID to avoid colliding with other running ping processes.
These are all just highlights from the full list of changes you can
find in our CHANGELOG.
With this stable version out of the way, we are diving headfirst into the
next development cycle. Many exciting features are in the queue, including:
A modern upgrade to the aging WinPcap is coming! We already have a
working replacement called Npcap
developed by GSoC student Yang Luo that is updated to use the NDIS 6 API and
LWF. Cooperating with the WinPcap group, we can be sure that these
improvements will be available in Nmap very soon.
Nmap on mobile devices is already a reality for Android, but we want to
expand support to other mobile platforms and perhaps develop a really useful
app interface, since console applications tend to be difficult to use on those
We are always working on improving performance, and you can expect we
will deliver. Nmap's --min-rate option has the potential to scale to
Internet-wide scans, and we intend to benchmark and demonstrate this ability.
More large-scale scanning research should help us improve the port popularity
rankings and fine-tune Nmap's internals for optimum performance.
It doesn't take a Nostrodamus to predict that NSE will continue to
expand at a blinding pace. We have dozens of NSE scripts waiting in the wings,
and pages of ideas for new ones. Maybe your name will grace our CHANGELOG as a
script author in the next release!
