NMap New Version 7.70 Released With Hundred of New OS And Service Fingerprints

Nmap Free Security Scanner, Port Scanner, & Network Exploration Tool. Download open source software for Linux, Windows, UNIX, FreeBSD, etc.

It includes hundreds of new OS and service fingerprints, 9 new NSE scripts (for a total of 588), a much-improved version of our Npcap windows packet capturing library/driver, and service detection improvements to make -sV faster and more accurate. 

And those are just a few of the dozens of improvements described below.

Nmap 7.70 source code and binary packages for Linux, Windows, and Mac are available for free

If you find any bugs in this release, please let us know on the Nmap Dev list or bug tracker as described at

Here is the full list of significant changes in NMAP:

• [Windows] We made a ton of improvements to our Npcap Windows packet capturing library ( for greater performance and stability, as well as smoother installer and better 802.11 raw framecapturing support. Nmap 7.70 updates the bundled Npcap from version 0.93 to 0.99-r2, including all these changes from the last seven Npcap releases:

• Integrated all of your service/version detection fingerprints submitted from March 2017 to August 2017 (728 of them). The signature count went up 1.02% to 11,672, including 26 new softmatches.  We now detect 1224 protocols from filenet-pch, lscp, and netassistant to sharp-remote, urbackup, and watchguard.  We will try to integrate the remaining submissions in the next release.

• Integrated all of your IPv4 OS fingerprint submissions from September 2016 to August 2017 (667 of them). Added 298 fingerprints, bringing the new total to 5,652. Additions include iOS 11, macOS Sierra, Linux 4.14, Android 7, and more.

• Integrated all 33 of your IPv6 OS fingerprint submissions from September 2016 to August 2017. New groups for OpenBSD 6.0 and FreeBSD 11.0 were added, as well as strengthened groups for Linux and OS X.

• Added the --resolve-all option to resolve and scan all IP addresses of a host.  This essentially replaces the resolveall NSE script. [Daniel Miller]

• [NSE][SECURITY] Nmap developer nnposter found a security flaw (directory traversal vulnerability) in the way the non-default http-fetch script sanitized URLs. If a user manualy ran this NSE script against a malicious web server, the server could potentially (depending on NSE arguments used) cause files to be saved outside the intended destination directory. Existing files couldn't be overwritten.  We fixed http-fetch, audited our other scripts to ensure they didn't make this mistake, and updated the httpspider library API to protect against this by default. [nnposter, Daniel Miller]

• [NSE] Added 9 NSE scripts, from 8 authors, bringing the total up to 588! They are all listed at, and the summaries are below:

   - deluge-rpc-brute performs brute-force credential testing against
   Deluge BitTorrent RPC services, using the new zlib library. [Claudiu Perta]
   - hostmap-crtsh lists subdomains by querying Google's Certificate
   Transparency logs. [Paulino Calderon]
   - [GH#892] http-bigip-cookie decodes unencrypted F5 BIG-IP cookies and
   reports back the IP address and port of the actual server behind the
   load-balancer. [Seth Jackson]
   - http-jsonp-detection Attempts to discover JSONP endpoints in web
   servers. JSONP endpoints can be used to bypass Same-origin Policy
   restrictions in web browsers. [Vinamra Bhatia]
   - http-trane-info obtains information from Trane Tracer SC controllers
   and connected HVAC devices. [Pedro Joaquin]
   - [GH#609] nbd-info uses the new nbd.lua library to query Network Block
   Devices for protocol and file export information. [Mak Kolybabi]
   - rsa-vuln-roca checks for RSA keys generated by Infineon TPMs
   vulnerable to Return Of Coppersmith Attack (ROCA) (CVE-2017-15361). Checks
   SSH and TLS services. [Daniel Miller]
   - [GH#987] smb-enum-services retrieves the list of services running on a
   remote Windows machine. Modern Windows systems requires a privileged domain
   account in order to list the services. [Rewanth Cool]
   - tls-alpn checks TLS servers for Application Layer Protocol Negotiation
   (ALPN) support and reports supported protocols. ALPN largely replaces NPN,
   which tls-nextprotoneg was written for. [Daniel Miller]

• [GH#978] Fixed Nsock on Windows giving errors when selecting on STDIN.
This was causing Ncat 7.60 in connect mode to quit with error: libnsock select_loop(): nsock_loop error 10038: An operation was attempted on something that is not a socket.  [nnposter]

• [Ncat][GH#197][GH#1049] Fix --ssl connections from dropping on renegotiation, the same issue that was partially fixed for server mode in [GH#773]. Reported on Windows with -e by pkreuzt and vinod272. [Daniel

• [NSE][GH#1062][GH#1149] Some changes to brute.lua to better handle misbehaving or rate-limiting services. Most significantly, brute.killstagnated now defaults to true. Thanks to xp3s and Adamtimtim for reporing infinite loops and proposing changes.

• [NSE] VNC scripts now support Apple Remote Desktop authentication (auth type 30) [Daniel Miller]

• [NSE][GH#1111] Fix a script crash in ftp.lua when PASV connection timed out. [Aniket Pandey]

• [NSE][GH#1114] Update bitcoin-getaddr to receive more than one response message, since the first message usually only has one address in it. [h43z]

• [Ncat][GH#1139] Ncat now selects the correct default port for a given proxy type. [Pavel Zhukov]

• [NSE] memcached-info can now gather information from the UDP memcached service in addition to the TCP service. The UDP service is frequently used as a DDoS reflector and amplifier. [Daniel Miller]

• [NSE][GH#1129] Changed url.absolute() behavior with respect to dot and dot-dot path segments to comply with RFC 3986, section 5.2. [nnposter]

• Removed deprecated and undocumented aliases for several long options that used underscores instead of hyphens, such as --max_retries. [Daniel Miller]

• Improved service scan's treatment of soft matches in two ways. First of all, any probes that could result in a full match with the soft matched service will now be sent, regardless of rarity. This improves the chances of matching unusual services on non-standard ports.  Second, probes are now skipped if they don't contain any signatures for the soft matched service.

Perviously the probes would still be run as long as the target port number matched the probe's specification.  Together, these changes should make service/version detection faster and more accurate.  For more details on how it works, see [Daniel Miller]

• --version-all now turns off the soft match optimization, ensuring that all probes really are sent, even if there aren't any existing match lines for the softmatched service. This is slower, but gives the most comprehensive results and produces better fingerprints for submission.
[Daniel Miller]

• [NSE][GH#1083] New set of Telnet softmatches for version detection based on Telnet DO/DON'T options offered, covering a wide variety of devices and operating systems. [D Roberson]

• [GH#1112] Resolved crash opportunities caused by unexpected libpcap version string format. [Gisle Vanem, nnposter]

• [NSE][GH#1090] Fix false positives in rexec-brute by checking responses for indications of login failure. [Daniel Miller]

• [NSE][GH#1099] Fix http-fetch to keep downloaded files in separate destination directories. [Aniket Pandey]

• [NSE] Added new fingerprints to http-default-accounts:
+ Hikvision DS-XXX Network Camera and NUOO DVR [Paulino Calderon]
+ [GH#1074] ActiveMQ, Purestorage, and Axis Network Cameras [Rob
Fitzpatrick, Paulino Calderon]

• Added a new service detection match for WatchGuard Authentication Gateway. [Paulino Calderon]

• [NSE][GH#1038][GH#1037] Script qscan was not observing interpacket delays
(parameter qscan.delay). [nnposter]

• [NSE][GH#1046] Script http-headers now fails properly if the target does not return a valid HTTP response. [spacewander]

• [Ncat][Nsock][GH#972] Remove RC4 from the list of TLS ciphers used by default, in accordance with RFC 7465. [Codarren Velvindron]

• [NSE][GH#1022] Fix a false positive condition in ipmi-cipher-zero caused by not checking the error code in responses. Implementations which return
an error are not vulnerable. [Juho Jokelainen]

• [NSE][GH#958] Two new libraries for NSE.
   - idna - Support for internationalized domain names in applications
   - punycode (a transfer encoding syntax used in IDNA) [Rewanth Cool]

• [NSE] New fingerprints for http-enum:
   - [GH#954] Telerik UI CVE-2017-9248 [Harrison Neal]
   - [GH#767] Many WordPress version detections [Rewanth Cool]

• [GH#981][GH#984][GH#996][GH#975] Fixed Ncat proxy authentication issues [nnposter]:

   - Usernames and/or passwords could not be empty
   - Passwords could not contain colons
   - SOCKS5 authentication was not properly documented
   - SOCKS5 authentication had a memory leak

• [GH#1009][GH#1013] Fixes to autoconf header files to allow autoreconf to be run. [Lukas Schwaighofer]

• [GH#977] Improved DNS service version detection coverage and consistency by using data from a Project Sonar Internet wide survey. Numerouse false positives were removed and reliable softmatches added. Match lines for version.bind responses were also conslidated using the technique below.
[Tom Sellers]

• [GH#977] Changed version probe fallbacks so as to work cross protocol (TCP/UDP). This enables consolidating match lines for services where the responses on TCP and UDP are similar. [Tom Sellers]

• [NSE][GH#532] Added the zlib library for NSE so scripts can easily handle compression. This work started during GSOC 2014, so we're particularly pleased to finally integrate it! [Claudiu Perta, Daniel Miller]

• [NSE][GH#1004] Fixed handling of brute.retries variable. It was being treated as the number of tries, not retries, and a value of 0 would result in infinite retries. Instead, it is now the number of retries, defaulting to 2 (3 total tries), with no option for infinite retries.

• [NSE] http-devframework-fingerprints.lua supports Jenkins server detection and returns extra information when Jenkins is detected [Vinamra Bhatia]

• [GH#926] The rarity level of MS SQL's service detection probe was decreased. Now we can find MS SQL in odd ports without increasing version intensity. [Paulino Calderon]

• [GH#957] Fix reporting of zlib and libssh2 versions in "nmap --version". We were always reporting the version number of the included source, even when a different version was actually linked. [Pavel Zhukov]

• Add a new helper function for nmap-service-probes match lines: $I(1,">") will unpack an unsigned big-endian integer value up to 8 bytes wide from capture 1. The second option can be "<" for little-endian. [Daniel Miller]

Enjoy this new release and please do let us know if you find any problems!
