I’m now providing an updated Linux Penetration Testing Laptop Setup document to help install popular and useful vulnerability assessment tools for the Linux operating system. You can go and obtain Backtrack but I feel that you will have more understanding of the tools and Linux in general if you install the tools yourself. You will also have the most current version available. See Configuration Tutorials for the latest document.

I created a tutorial on how to setup and configure the Nokia N810 Internet Tablet to conduct a wireless assessment or audit. The tools included in the tutorial include how to setup kismet (oldcore and newcore), aircrack-ng (airbase and aircrack), and btscanner. I’m still working on developing steps to install Metasploit and Karmetasploit for wireless client attacks. The tutorial also details using the internal GPS as well as adding an external wireless adapter. The latest version of the tutorial can be found here.

I put together another Technical Assessment Plan for assessing the SNMP protocol. You will use open source and freely download-able utilities to assess the SNMP protocol. This is for auditors that do not have access to or cannot afford the Solarwinds toolset. This is version 0.1 of the document and I plan on making updates and add new tools in the future.

I put together a Technical Assessment Plan that can be used to conduct external fingerprinting using the tools and utilities that a penetration tester would use. The assessment plans are structured in a way to help with the documentation of evidence for inclusion in a work-paper process. The plan provides helpful information on how to install, configure, and use the tools to obtain the evidence needed for an engagement. The Technical Assessment Plans that I have created can be found here.
9.19.2011 – Updated for latest openssl and john jumbo patch on Ubuntu Natty Narwhal 11.4
Password cracking Windows hashes on Linux using John the Ripper (JtR). If you prefer the Linux operating system JtR is the password cracking utility to use. By default JtR does not support the hashes that we are interested in cracking. See below for installation and patching instructions for JtR. Applying the patch to JtR adds the functionality to crack NTLM and MS-Cache passwords. NOTE: This install was done on Ubuntu 10.4 LTS but should work on any Linux system since we are compiling from source.
$./john --format=mscash --rules --wordlist=<PASSWORD_LIST> <CACHE_HASH_FILE>
$./john --format=nt --rules --wordlist==<PASSWORD_LIST> <NTLM_HASHE_FILE>
For additional information you can read the JtR documentation and wiki from Openwall.
OpenSSL is needed. This can be installed through your package manager or may already be installed. Remember to install the development package (libssl-dev or libssl-devel). Instructions on download and compile are included below.
JtR 1.7.8
$ wget http://www.openssl.org/source/openssl-1.0.0e.tar.gz
$ tar zxvf openssl-1.0.0e.tar.gz
$ cd openssl-1.0.0e
$ ./config --openssldir=/usr/local
$ make
$ sudo make install
$ wget http://www.openwall.com/john/g/john-1.7.8-jumbo-5.tar.gz
$ tar zxvf john-1.7.8-jumbo-5.tar.gz
$ cd john-1.7.8-jumbo-5/
$ cd src/
$ make linux-x86-64
$ sudo make install
JtR 1.7.7
$ wget http://www.openssl.org/source/openssl-1.0.0d.tar.gz
$ tar zxvf openssl-1.0.0d.tar.gz
$ cd openssl-1.0.0d
$ ./config --openssldir=/usr/local
$ make
$ sudo make install
$ cd ..
$ wget http://download.openwall.net/pub/projects/john/1.7.7/john-1.7.7.tar.gz
$ tar zxvf john-1.7.7.tar.gz
$ cd john-1.7.7/
$ wget http://download.openwall.net/pub/projects/john/1.7.7/john-1.7.7-jumbo-6.diff.gz
$ gzip -d john-1.7.7-jumbo-6.diff.gz
$ patch -p1 < john-1.7.7-jumbo-6.diff
$ cd src/
$ make linux-x86-sse2
John will be found in the run directory.

I have created an updated configuration document for my Motion Computing m1300 wireless tablet. This document details getting Ubuntu 8.04 LTS Hardy Heron up and running on the tablet. Included in the documentation are the steps to get Kismet, Aircrack-ng, and Karmasploit up and running. Those steps will be helpful no matter what hardware you install Ubuntu on.
I have also created an updated configuration document for the setup of my Linux laptop that I use for penetration testing.

At the NSAA IT Conference and Workshop, put on by NASACT, I presented on Auditing Windows Account Management. I’m posting the slides to my presentation as reference. I would love any feedback from anybody who attended the presentation. The tool PWDumpX was demonstrated during the presentation. A document on how to use the tool to obtain Windows Domain account password hashes has been posted.
