Metagoofil

This tool is oriented to the extraction of metadata from files published in the domains of the target. It looks into the following type of files : PDF, PPT, DOC, XLS and MDB, and looks into different relevant fields, like "Author" or "Last Saved by".

The idea is to look into fields that may be used to get information about users, so can be used for brute-force attacks. This information can also provide windows domain users, or the methodology used by the company to generate user names.

Once the docs are identified, they are downloaded and analyzed. The information is presented in an HTML document. Please feel free to use this tool and don´t heasitate to send us your feedback.

Download: metagoofil-1.2.tar

Protocols, Data structures and File formats

Recently i discover the website Wotsit.org, is a place where you can find information of Data Structures, Protocols, File Formats, etc. It's a valuable resource for creating fuzzing tools, analyzing protocols, or develop a tool.
Really a must have in the security professional bookmarks!

Site: Wotsit

Wfuzz, proxys and webserver scanning

Yesterday i was performing a pentest on a very big network. After struggling a bit i managed to upload files to a web server, an antivirus was running so many known tools didn't work, so it's time for more creativity. I pulled the http-proxy, a python based proxy developed by Edge-security, and compiled it into binary with py2exe, created an self-extracting zip, and uploaded to the server. I configured the proxy to listen on the port 53, as they leave that port unfiltered, neat :P

Well, so far so good, now i needed to know which machines were running webservers. I could have programmed a python scanner and upload it, but i was running out of time, so i went for wfuzz, the swiss knife for application testing (every body says their tool is a swiss knife), i used this command line to scan for web servers in the internal LAN through the proxy:

me ----> Server w/proxy ---->LAN

wfuzz -x serverip:53 -c -z range -r 1-254 --hc XXX -t 5 http://10.10.1.FUZZ

Some wfuzz switchs:

-x set proxy
--hc is used to hide the XXX error code from the results, as machines w/o webserver will fail the request (this is added on the new version).

With this command line, i will get every web server on the segment 10.10.1.X, i had to repeat this line for every segment the compromised server could reach, just that easy, fast and fun.

The http-proxy i used is part of the next framework that is being baked at Edge-security, stay tuned..

See you soon

New tools and some docs..

Hi i'm back from the vacations, i will start posting more frequently than before, it's an objetive that i set.

Well let's move on the first post, it is about some new tools and documents from the last weeks.

Docs:

Blackhat and Defcon are over, and the presentations and whitepapers could be downloaded from here:

Blackhat: http://164.106.251.250/docs/netsec/bh2007/
Defcon: http://164.106.251.250/docs/dc15/

There are a lot of presentations, and some are really good.


Tools:

Nmap-SOC:
First Nmap SOC release! Nmap 4.22SOC1

The new nmap version is available, with all the improvements proposed in the Summer Of Code (Google). Some of the highlights are:

-The UMIT graphical Nmap frontend is now included
-The port selection mechanism was overhauled
-Added the --reason option which explains WHY Nmap assigned a port status
-Integrated all of your 2nd generation OS detection submissions, increasing the database size by 68% since 4.21ALPHA4 to 699 fingerprints.
-Added --servicedb and --versiondb command-line options which allow you to specify a custom Nmap services (port to port number translation and port frequency) file or version detection database.
-In verbose mode, Nmap now reports where it obtains data files (such as nmap-services) from.

These are some of the more significant (at least for me), there are many more improvements on the release.

Information: http://seclists.org/nmap-dev/2007/q3/0030.html


Umit: Nmap frontend.

Really a very good frontend, with a lot of functionalities, like comparing between different scans, saving scans, multiple tabs, profiles, information highlighting, etc. This project is sponsored by the Google Summer Of Code.

Install: http://umit.sourceforge.net/install.html
Blog: http://umitproject.blogspot.com/




Evolution: Massive information Gathering.

Evolution is a program that can be used to determine the relationships and real world links between different entities. Really it worths a try. I liked a lot the GUI, is still in beta stage, but is really awesome the interface.

Presentations: http://www.paterva.com/web/Evolution/Presentations/

Immunity Debugger:

The new toy from Immunity guys, this is a new debugger oriented for vulnerability analysis, and security related task. It's programmed in python :), you can load python scripts to aid the analysis. Immunity says:

-A debugger with functionality designed specifically for the security industry
-Cuts exploit development time by 50%
-Simple, understandable interfaces
-Robust and powerful scripting language for automating intelligent debugging
-Lightweight and fast debugging to prevent corruption during complex analysis
-Connectivity to fuzzers and exploit development tools



Really a very good tool.

That's all for today :)

Metasploit GUI & Assistant

After a long waiting, a cool Metasploit GUI is available. In the development version of the metasploit is available the GUI with the new Metasploit::Assistant.

I think this is a great advance, and step by step the project is getting near the commercial options (Canvas, Core Impact). Right now Metasploit has 187 exploits, 106 payloads and many more

One great thing of this Framework is that runs on the Nokia 770/800, i hope for the GUI to run on the Nokia soon, it will be very easy to hack on the move, not typing in the mini X-term. Someone to port ruby-libglade and ruby-gtk2?


Next, Next, Next, Own3d ;)


For installing in Backtrack2 Final:

1-Download the following files:

ruby-gtk2
ruby-libglade2

2-Execute these commands:

# lzm2dir ruby-gtk2-0.16.0.lzm /
# lzm2dir ruby-libglade2-0.16.lzm /

# cd /pentest/exploits/framework3
# svn update
# ./msfgui


And here are some screenshots of the GUI running:

Wfuzz update!

We did some bug cleaning, and some improvements to our wfuzz. Now it supports colored output on Windows machines!, we added support for fuzzing all GET and POST variables with one command, and we also tackle some errors.

If you find an error please send us an email, also if you have a new dictionary please help with the project and send it to us ;)

Check the new version: Wfuzz

My new Nokia 770!

Im very happy with my new Nokia 770, its an Internet Tablet that is between a mobile phone and a mini computer. It has an ARM processor, MMC memory, Wlan, Bluetooth, and an impressive 800x480 screen.

The cool thing is that is based on Debian Linux (Kernel 2.6.12). I bought it because i wanted to do some test and try to build a Security testing device, im developing a GUI based bluetooth scanner, and coding some Python tools. :)

There are available tools like: nmap, ettercap, aircrack-ng, kismet, rdesktop, and many more!


Here are some photos:

Wfuzz, the web bruteforcer is here...

It's been a while since the last tool were released, with deepbit we were working on a tool for Web Application testing, based on bruteforcing, very fast and useful. It can bruteforce GET and POST parameters, unlinked resources (directories, servlets, scripts), etc. It was used during our latest pentest and it shielded very good results. In the package is included a lot of dictionaries tailored for known applications like Weblogic, Websphere, Tomcat, IIS, Apache, Vignette, Fatwire, and many many more (thanks to Darkraver for letting us using Dirb's dictionaries).

Right now the ouput could be the console and a html file. The last one, is very useful for checking the results in the browser, and if you bruteforced a POST parameter, it will create a button in the Html that will send all the POST data, very cool.

If you are a pentester, you must have it ;)

Please check the Wfuzz page.

Blackhat Europe 2007

Hi i'm back from Blackhat Amsterdam, and i really didn't liked it this time. I'm very disappointed with the organization, when i pay 1200 Eur i expect that the service and the organization of the event will be perfect (or at least very good), but this time it looked like a bunch of friends organized some conference without too much interest. Here is the list of things that i didn't liked:

0-Please stop giving for free those red bags, not even our girlfriends use them, they are totally ugly.

1-This year they didn't gave books, only the Cd-rom. (the book was ok, because you can take notes, read a slide that you miss, etc).

2-The organization wanted that the public use their laptops to read the cdroms, but in the conference room there were few sockets.

3-The lunch was a nightmare, the people had to wait in a queue to enter the restaurant, then make a queue to serve the food. Really a mess...

4-There were zero support for the speakers, some speakers had problems and there were nobody from the organizations to help them. For example one speaker had the audio
very low, and the public hardly heard him, nobody helped him until one person went outside to search for someone of the crew to fix the problem. Other speaker had a problem with his laptop socket and again, nobody from the crew was there.

5-The Microsoft party was a shame in comparison with 2006. Prefixed drinks, small place, it was more like a reunion in the house of a friend than a party :( (i think they spend all the budget in Windows Vista Marketing) ;)

6-The place was very small, and it was difficult to move when all the people was in the lobby.

7-There were coffe service with some food, but it was difficult to have a glass of water. Coffe a lot, water none.


That's all my thoughts, if they want to charge 1200 Eur, for the conference they have to mantain a quality level. From this year experience i don't recommend Blackhat Europe the next time.

If you have any question about blackhat, please let me know..

coLinux - Cooperative Linux





Some time ago i switched from Ubuntu to Windows XP (in my work computer), mostly because it made my work easier and faster ,but i always missed the linux command line and all the tools. I tried Cygwin, it's not too bad but still is not Linux. Yesterday a co-worker (Ruben) showed me coLinux:

From the coLinux site:
Cooperative Linux is the first working free and open source method for optimally running Linux on Microsoft Windows natively. More generally, Cooperative Linux (short-named coLinux) is a port of the Linux kernel that allows it to run cooperatively alongside another operating system on a single machine.

In short words, it's like Vmware, Parallels, Virtual PC but free, lighter and faster. It take just 4 seconds to boot a debian sarge!!

So now i have a real full linux in my Windows environment :)



Right now there are available Debian, Fedora, Gentoo, Ubuntu, Mandrake and many more OS images.

Best of all you can start coLinux machine as a Windows service an access via SSH through your favorite Terminal emulator (Poderosa, Putty, etc).

Just Great..

coLinux official page
coLinux Wiki

But still not even Windows and Linux together, can beat the MacOs X ;)
There is nothing like MacOs X with Parallels, running windows applications directly in the Os X desktop. (Coherence mode)





Enjoy...

MD5 and SHA1


The other day i needed to crack a MD5 string and i hadn't the Rainbow Tables at hand so a partner show me the web http://md5.rednoize.com. It is very cool, and it also support SHA1, and it looks like google :)

The web does:

-Plaintext --> MD5
-Plaintext --> SHA1

-MD5 --> Plaintext
-SHA1 --> Plaintext

In the future i will add more website that offer this kind of service.
Enjoy

SSH Dinamic Port Forwarding

This is a mind note, cause i always forgot the command to create a dinamic port forwarding through ssh. Suppose you want to navigate the web with your browser but you want that the browser connection is made by other machine that has sshd running. So you can access web pages as if from the other machine.

You need to create a connection to the sshd server with the parameter -D and the port number where the local machine will listen to forward the connections. Example:

command>ssh myuser@sshdserver -D 8080


Now you have to configure the web browser to use SOCK Host: localhost Port:8080

In windows you can use putty, and you have to configure

Connection->SSH->Tunnel
Option: Source Port = 8080
Destination: Dinamic

That's all

Email Harvesting

I made an update to an old but useful tool, "googleharvester". Now the tool also works with msn search. I ported the program to Python because i feel more comfortable with the language and i program faster ;)
You can download the tool: Here

Now the tool is called "theHarvester"

Ngsec - Game #3 - Brainstorming

Well another Web application hacking game from Ngsec, this time there were 5 levels. The difficulty was very hard at the 2 first levels, and very very easy in the last 3. The order of the levels should have been inverse :) . But with some patience and Mandingo's tips, i finished in 9 hours aprox (not in a row).

It's was good game to kill some time and program a little.

Try it and became a g00r00 ;)

Game #3

Some tips:
Level 1 - I become blind.
Level 2 - Timing, it's all about timing.
Level 3 - Too easy, no tips.
Level 4 - With the tips and clues in the game, plus some tampering should be enough.
Level 5 - Very easy, just google.
