Nmap 4.85BETA7 Released to Scan for Conficker Worm

The Conficker worm is receiving a lot of attention because of itsvast scale (millions of machines infected) and advanced updatemechanisms. Conficker isn't the end of the Internet (despite some ofthat hype), but it is a huge nuisance we can all help to cleanup.

Thanks to excellent research by Tillmann Werner and Felix Lederof The Honeynet Project andimplementation work by Ron Bowes, David Fifield, Brandon Enright, andFyodor, we've rolled out a new Nmap release which can remotely scanfor and detect infected machines. Nmap 4.85BETA7 is now availablefrom the download page,including official binaries for Windows and Mac OS X. To scan forConficker, 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:

  • Fyodor spent much of this summer scanning tens of millions of IPs on the Internet (plus collecting data contributed by some enterprises) to determine the most commonly open ports. Nmap now uses that empirical data to scan more effectively.
  • Zenmap Topology and Aggregation features were added, as discussed in the next news item.
  • Hundreds of OS detection signatures were added, bringing the total to 1,503.
  • Seven new Nmap Scripting Engine (NSE) scripts were added. Theseautomate routing AS number lookups, “Kaminsky” DNS bugvulnerability checking, brute force POP3 authentication cracking, SNMPquerying and brute forcing, and whois lookups against target IP space.Many valuable libraries were added as well.
  • Many performance improvements and bug fixes were implemented. Inparticular, Nmap now works again on Windows 2000.

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 beenable to actually draw you a map of the network—until now! Thenew Zenmap NetworkTopology feature provides an interactive, animated visualizationof the hosts on a network and connections between them. The scansource is (initially) in the center, with other hosts on a series ofconcentric circles which represent the number of hops away they arefrom the souce. Nodes are connected by lines representing discovered paths between them. Read the full details (and oogle the pretty pictures)in our articleon Surfing theNetwork Topology. Special thanks go to João Medeiros,David Fifield, and Vladimir Mitrovic for their tireless work indeveloping and integrating this new feature.

Another exciting new Zenmap featureis scanaggregation, which allows you to combine the results of many Nmapscans into one view. When one scan is finished, you may start anotherin the same window. Results of the new scan are seamlessly mergedinto one view.

Download

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

  • Fyodor spoke in Las Vegas at the Black Hat Briefings and Defcon to discuss the results of large-scale Internetscans he has been conducting, and demonstrate how you can use theempirical data to make your scans (over the Internet or even internal)more efficient. He also showed off some newNmap features which can help you bypass firewall restrictions, reducescan times, and gather more information about remote hosts. The presentation video is now available on the presentations page.
  • RSS feeds for mailing lists archived by SecLists.Org now sport message excerpts to make it easier to identify interesting messages.
  • We now have a working search engine which covers all of our sites(Insecure.Org, Nmap.Org, SecLists.Org,and SecTools.Org. You can find thesearch bar on the left sidebar or bottom of our normal pages,or visit our search pagedirectly.
  • And for a bit of fun news, Nmap's movie stardom has grown with an appearance in its seventh movie!

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, freeavailability 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 includethe Zenmap cross-platformGUI, 2nd GenerationOS Detection, the Nmap Scripting Engine, a rewritten host discovery system, performanceoptimization, advanced traceroute functionality, TCP and IP options support, and nearly 1,500 new version detection signatures. Dozens ofother 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.

NSA Loads Nmap Release Status for President Bush Visit

US President George W. Bush visited the NSA headquarters at FortMeade in January 2006. A wall-sized status screen in the backgrounddisplays the latest versions of Nmap and some of our other favorite open source tools. Pictures were printed in theFebruary 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 announcethat the Nmap man page has been completely rewritten. It is morecomprehensive (double the length) and much better organized than theprevious one. It is meant to serve as a quick-reference to virtuallyall Nmap command-line arguments, but you can learn even more aboutNmap by reading it straight through. The 18 sections include BriefOptions Summary, Firewall/IDSEvasion and Spoofing, Timingand Performance, PortScanning Techniques, UsageExamples , and much more. It even documents some cool featuresthat are slated for release in the next Nmap version (runtimeinteraction and parallel DNS resolution).

The new man page is best read in HTML format, though youcan alternatively download the Nroff nmap.1 toinstall 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 electronicfinancial heist. While the work is fiction, hacks are described indepth using real technology such as Nmap, Hping2, OpenSSL, etc. Stealing the Network: How to Own a Continent can be purchasedat Amazon (save $17), and your can readFyodor's chapter online for free. STC was a best-seller, ranking for a while as the second-highest sellingcomputer 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 insteadof using a simple nmap-services table lookup to determine a port'slikely purpose, Nmap will (if asked) interrogate that TCP or UDPport to determine what service is really listening. In many cases itcan determine the application name and version number as well.Obstacles like SSL encryption and Sun RPC are no threat, as Nmap canconnect using OpenSSL (if available) as well as utilizing Nmap's RPCbruteforcer. IPv6 is also supported. You can read our new version detection paper for thedetails and examples, or just download the latest version and try itout here. Simply add '-sV' to your normal scancommand-line options.

Nmap Featured in The Matrix Reloaded

We have all seen many movies like Hackers which pass offridiculous 3D animated eye-candy scenes as hacking. So I wasshocked to find that Trinity does it properly in The Matrix Reloaded [Under $6 at Amazon].She whips out Nmap version2.54BETA25, usesit to find a vulnerable SSH server, and then proceeds to exploit itusing the SSH1CRC32 exploit from 2001.Shame on them for being vulnerable (timing notes).

Nodes are connected by lines representing discovered paths between them. Read the full details (and oogle the pretty pictures)in our articleon Surfing theNetwork Topology. Special thanks go to João Medeiros,David Fifield, and Vladimir Mitrovic for their tireless work indeveloping and integrating this new feature.

Another exciting new Zenmap featureis scanaggregation, which allows you to combine the results of many Nmapscans into one view. When one scan is finished, you may start anotherin the same window. Results of the new scan are seamlessly mergedinto 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

  • Fyodor spoke in Las Vegas at the Black Hat Briefings and Defcon to discuss the results of large-scale Internetscans he has been conducting, and demonstrate how you can use theempirical data to make your scans (over the Internet or even internal)more efficient. He also showed off some newNmap features which can help you bypass firewall restrictions, reducescan times, and gather more information about remote hosts. The presentation video is now available on the presentations page.
  • RSS feeds for mailing lists archived by SecLists.Org now sport message excerpts to make it easier to identify interesting messages.
  • We now have a working search engine which covers all of our sites(Insecure.Org, Nmap.Org, SecLists.Org,and SecTools.Org. You can find thesearch bar on the left sidebar or bottom of our normal pages,or visit our search pagedirectly.
  • And for a bit of fun news, Nmap's movie stardom has grown with an appearance in its seventh movie!

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, freeavailability 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 includethe Zenmap cross-platformGUI, 2nd GenerationOS Detection, the Nmap Scripting Engine, a rewritten host discovery system, performanceoptimization, advanced traceroute functionality, TCP and IP options support, and nearly 1,500 new version detection signatures. Dozens ofother 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.

SecLists.Org Back Up and Running

Our popular SecLists.Org publicmailing list archive is back up and running after it was inexcusablyshut down with no notice by our soon-to-be-former domain registrarGoDaddy 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 FortMeade in January 2006. A wall-sized status screen in the backgrounddisplays the latest versions of Nmap and some of our other favorite open source tools. Pictures were printed in theFebruary 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 announcethat the Nmap man page has been completely rewritten. It is morecomprehensive (double the length) and much better organized than theprevious one. It is meant to serve as a quick-reference to virtuallyall Nmap command-line arguments, but you can learn even more aboutNmap by reading it straight through. The 18 sections include BriefOptions Summary, Firewall/IDSEvasion and Spoofing, Timingand Performance, PortScanning Techniques, UsageExamples , and much more. It even documents some cool featuresthat are slated for release in the next Nmap version (runtimeinteraction and parallel DNS resolution).

Nmap For Mac Os

The new man page is best read in HTML format, though youcan alternatively download the Nroff nmap.1 toinstall 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

Download Nmap For Mac Os X


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 electronicfinancial heist. While the work is fiction, hacks are described indepth using real technology such as Nmap, Hping2, OpenSSL, etc. Stealing the Network: How to Own a Continent can be purchasedat Amazon (save $17), and your can readFyodor's chapter online for free. STC was a best-seller, ranking for a while as the second-highest sellingcomputer 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 insteadof using a simple nmap-services table lookup to determine a port'slikely purpose, Nmap will (if asked) interrogate that TCP or UDPport to determine what service is really listening. In many cases itcan determine the application name and version number as well.Obstacles like SSL encryption and Sun RPC are no threat, as Nmap canconnect using OpenSSL (if available) as well as utilizing Nmap's RPCbruteforcer. IPv6 is also supported. You can read our new version detection paper for thedetails and examples, or just download the latest version and try itout here. Simply add '-sV' to your normal scancommand-line options.

Nmap Featured in The Matrix Reloaded

Nmap Get Mac Address

We have all seen many movies like Hackers which pass offridiculous 3D animated eye-candy scenes as hacking. So I wasshocked to find that Trinity does it properly in The Matrix Reloaded [Under $6 at Amazon].She whips out Nmap version2.54BETA25, usesit to find a vulnerable SSH server, and then proceeds to exploit itusing the SSH1CRC32 exploit from 2001.Shame on them for being vulnerable (timing notes). Congratulations to everyone who has helpedmake Nmap successful! Click on these thumbnails for higher resolution or view more pictureshere.
