Nmap 4.85BETA7 Released to Scan for Conficker Worm

The Conficker worm is receiving a lot of attention because of its vast scale (millions of machines infected) and advanced update mechanisms. Conficker isn't the end of the Internet (despite some of that hype), but it is a huge nuisance we can all help to clean up.

Thanks to excellent research by Tillmann Werner and Felix Leder of The Honeynet Project and implementation work by Ron Bowes, David Fifield, Brandon Enright, and Fyodor, we've rolled out a new Nmap release which can remotely scan for and detect infected machines. Nmap 4.85BETA7 is now available from the download page, including official binaries for Windows and Mac OS X. To scan for Conficker, use a command such as:
nmap -PN -T4 -p139,445 -n -v --script smb-check-vulns,smb-os-discovery --script-args safe=1 [targetnetworks]

You will only see Conficker-related output if either port 139 or 445 are open on a host. A clean machine reports at the bottom: “Conficker: Likely CLEAN”, while likely infected machines say: “Conficker: Likely INFECTED”. For more advice, see this nmap-dev post by Brandon Enright.

While Conficker gets all the attention, 4.85BETA7 also has many other great improvements.

Update: Changed version from 4.85BETA5 (first to detect Conficker) to 4.85BETA7, which includes further Conficker detection improvements, among other changes.

Nmap 4.75 Released

We are pleased to release Nmap 4.75, with almost 100 significant improvements since version 4.68. Key Nmap 4.75 changes include:

Many of these changes were discussed in Fyodor's Black Hat and Defcon presentations. The audio and video has now been posted on the presentations page.

Download the source tarball or binaries for Linux, Windows, or Mac OS X from the Nmap download page. If you find any bugs, please report them.

Zenmap Gains Topology Maps and Aggregation Features

While Nmap stands for “Network Mapper”, it hasn't been able to actually draw you a map of the network—until now! The new Zenmap Network Topology feature provides an interactive, animated visualization of the hosts on a network and connections between them. The scan source is (initially) in the center, with other hosts on a series of concentric circles which represent the number of hops away they are from the souce. Nodes are connected by lines representing discovered paths between them. Read the full details (and oogle the pretty pictures) in our article on Surfing the Network Topology. Special thanks go to João Medeiros, David Fifield, and Vladimir Mitrovic for their tireless work in developing and integrating this new feature.

Another exciting new Zenmap feature is scan aggregation, which allows you to combine the results of many Nmap scans into one view. When one scan is finished, you may start another in the same window. Results of the new scan are seamlessly merged into one view.

You can try these and many other great features with the latest version of Zenmap, available from the Nmap download page.

Nmap Summer News Roundup

Nmap Celebrates 10th Anniversary With Major Version 4.50 Release

After nearly two years of work since the 4.00 release, Insecure.Org is pleased to announce the immediate, free availability of the Nmap Security Scanner version 4.50 from https://nmap.org . Nmap was first released in 1997, so this release celebrates our 10th anniversary!

Major new features since 4.00 include the Zenmap cross-platform GUI, 2nd Generation OS Detection, the Nmap Scripting Engine, a rewritten host discovery system, performance optimization, advanced traceroute functionality, TCP and IP options support, and nearly 1,500 new version detection signatures. Dozens of other important changes—and future plans for Nmap—are listed in the release announcement. We recommend that all current Nmap users upgrade.

Update: Joe Barr at Linux.Com has written a great review of Nmap 4.50. In addition to testing the new features, he offers substantial background information on port scanning.

Nmap Featured in The Bourne Ultimatum

In The Bourne Ultimatum (IMDB), the CIA needs to hack the mail server of a newspaper (The Guardian UK) to read the email of a reporter they assassinated. So they turn to Nmap and its new official GUI Zenmap to hack the mail server! Nmap reports that the mail server is running SSH 3.9p1, Posfix smtpd, and a name server (presumably bind). They also make substantial use of Bash, the Bourne-again shell. Congratulations to Roger Chui for being the first to spot this. He also sent a scene transcript and the following HD screen shots (click for full resolution):

Other movies which have used Nmap include: Matrix Reloaded, Bourne Ultimatum, 13: Game of Death, Battle Royale, The Listening, and, uhh, HaXXXor: No Longer Floppy. Screens shots of Nmap in all of these movies are available on our new Nmap movies page. Nmap has become quite the movie star!

Introducing Zenmap, the Official Nmap GUI

After more than two years of development (starting with a 2005 Google Summer of Code project), we have replaced the venerable but dated NmapFE with a new cross-platform GUI named Zenmap. It is cross platform (tested on Linux, Windows, Mac OS X) and supports all Nmap options. Its results viewer allows easier browsing, searching, sorting, and saving of Nmap results.

Zenmap will appear in the upcoming 4.50 release and is already available in the release candidate packages on the Nmap download page. Zenmap screenshots and documentation are available at https://nmap.org/zenmap.

Zenmap is still under active development, but was integrated early because it is already much more powerful than NmapFE. Development is coordinated on the nmap-dev mailing list.

Nmap Featured in Die Hard 4

Yippee Ki-Yay! In Die Hard 4: Live Free or Die Hard (Wikipedia, IMDB), Detective John McClane (Bruce Willis) is dispatched to retrieve hacker Matthew Farrell (Justin Long) because the FBI suspects him of breaching their computer systems. Later, Justin is enlisted to help thwart terrorist mastermind Thomas Gabrial's attempts at total World destruction. In this Scene, Farrell demonstrates his Nmap skills:

Thanks to Andrew Hake for catching the cameo and sending these HD screen shots.

Top 100 Security Tools List Released

After the tremendously successful 2000 and 2003 top security tools surveys, we are pleased to release our 2006 results at a brand new site: SecTools.Org. A record 3,243 Nmap users responded this year. Notable trends since 2003 include the rise in exploitation frameworks such as Metasploit, Impact, and Canvas; the increased popularity of wireless tools such as Kismet and Aircrack. 44 tools are new to the list. Security practitioners are encouraged to read the list and investigate tools they aren't familiar with. You may find the little gem that you never knew you needed.

SecLists.Org Back Up and Running

Our popular SecLists.Org public mailing list archive is back up and running after it was inexcusably shut down with no notice by our soon-to-be-former domain registrar GoDaddy at the behest of MySpace.Com. We believe web site content is the responsibility of the site owner (registrant) and (if that fails) hosting or bandwidth provider. If the whois contact data is valid, registrars shouldn't be involved without a court order.

NSA Loads Nmap Release Status for President Bush Visit

US President George W. Bush visited the NSA headquarters at Fort Meade in January 2006. A wall-sized status screen in the background displays the latest versions of Nmap and some of our other favorite open source tools. Pictures were printed in the February 6, 2006 edition of Newsweek (article) and the Jan 27 Washington Post (article). The page on the screen is the Talisker Radar. We don't like the NSA tracking our phone calls and email, but they may track Nmap releases all they want.

Loading an external web site on their giant screen was risky. Imagine if this happened (thanks php0t)!
Meanwhile, Nmap makes an appearance at Walmart with the Nmap hacking chair

New Nmap Man Page

We are proud to announce that the Nmap man page has been completely rewritten. It is more comprehensive (double the length) and much better organized than the previous one. It is meant to serve as a quick-reference to virtually all Nmap command-line arguments, but you can learn even more about Nmap by reading it straight through. The 18 sections include Brief Options Summary, Firewall/IDS Evasion and Spoofing, Timing and Performance, Port Scanning Techniques, Usage Examples , and much more. It even documents some cool features that are slated for release in the next Nmap version (runtime interaction and parallel DNS resolution).

The new man page is best read in HTML format, though you can alternatively download the Nroff nmap.1 to install on your system.

We have issued a call for translations of the reference guide, and 29 languages are in progress. See the new documentation page to volunteer or read a translation.

Hacker Fiction Books Published

Fyodor has co-authored a novel on hacking, along with FX, Joe Grand, Kevin Mitnick, Ryan Russell, Jay Beale, and several others. Their individual stories combine to describe a massive electronic financial heist. While the work is fiction, hacks are described in depth using real technology such as Nmap, Hping2, OpenSSL, etc. Stealing the Network: How to Own a Continent can be purchased at Amazon (save $17), and your can read Fyodor's chapter online for free. STC was a best-seller, ranking for a while as the second-highest selling computer book on Amazon.

Update: Syngress has released a sequel: Stealing the Network: How to Own an Identity. They have generously allowed Fyodor to post his favorite chapter for free. So enjoy Bl@ckTo\/\/3r, by Nmap contributor Brian Hatch. It is full of wry humor and creative security conundrums to keep the experts entertained, while it also offers security lessons on the finer points of SSH, SSL, and X Windows authentication and encryption.

Nmap Gains Advanced Version Detection

After several months of intense private development, we are pleased to release Nmap 3.45, including an advanced version detection system. Now instead of using a simple nmap-services table lookup to determine a port's likely purpose, Nmap will (if asked) interrogate that TCP or UDP port to determine what service is really listening. In many cases it can determine the application name and version number as well. Obstacles like SSL encryption and Sun RPC are no threat, as Nmap can connect using OpenSSL (if available) as well as utilizing Nmap's RPC bruteforcer. IPv6 is also supported. You can read our new version detection paper for the details and examples, or just download the latest version and try it out here. Simply add "-sV" to your normal scan command-line options.

Nmap Featured in The Matrix Reloaded

We have all seen many movies like Hackers which pass off ridiculous 3D animated eye-candy scenes as hacking. So I was shocked to find that Trinity does it properly in The Matrix Reloaded [Under $6 at Amazon]. She whips out Nmap version 2.54BETA25, uses it to find a vulnerable SSH server, and then proceeds to exploit it using the SSH1 CRC32 exploit from 2001. Shame on them for being vulnerable (timing notes). Congratulations to everyone who has helped make Nmap successful! Click on these thumbnails for higher resolution or view more pictures here.
