Distribution of the week: BackTrack — Network Security Suite

BackTrack is Live distribution for penetration and security tests. This is how its developers describe it. But there are plenty of tools, utilities, programs behind this brief description. Let’s dig into.

This distribution started from the merge of two ones: WHAX (or Whoppix) and Auditor Security Collection (the swiss army knife for security assessments). The latest stable version (BackTrack 3) contains more than 300 tools (including such monsters as wireshark, nmap, hping and others) which will be appreciated by every security professional. All tools are categorized into:

1. Information gathering
2. Network Mapping
3. Vulnerability Identification
4. Penetration
5. Privilage Escalation
6. Maintaining Access
7. Covering Tracks
8. Radio Network Analysis (Wi-Fi and Bluetooth)
9. VoIP and Telephony Analysis
10. Digital Forensics
11. Reverse Engineering

The full list of tools with descriptions you can find at official BackTrack wiki, screenshots and documentation are here.

Speedlinks – 29 December, 2008

1. Linux kernel 2.6.28 was officially released at 28 Dec, 2008: ext4, graphics execution manager (GEM), TAINTed_CRAP. See First Look by arstechnica.com.

P.S. Linus “almost Santa” Torvalds’ announcement is definitely worth reading:

Listen to the cheerful grinding of your harddisk as you reboot into an all-new kernel – and I’m sure that if your computer could smile, it would have a big silly grin on its non-existent face. So as you sit there in your basement, give your computer the holiday cheer too.

2. Top 10 Coolest Open Source Applications in 2008. Well, good reading in New Year Eve.

3. Bootable FSF membership cards: USB flash drive comes with pre-installed gNewSense 2.1.

4. Sabayon Linux 4.0 is realeased (smart Gentoo based distro): 25% boot speed gain, 8500 applications, ext4, KDE 4.1.3, Gnome 2.24.2, OpenOffice.org 3.0, Firefox 3.0 and more…

5. Pidgin 2.5.3 is out. Best GTK based instant messenger is ready for downloading. Changelog.

Open .docx documents in Linux (OpenOffice)

Well, as for now it is not a problem anymore to open Microsoft Office 2007 .docx documents in any Linux distribution coming with OpenOffice suit. It may be Ubuntu (Feisty, Gutsy, Interpid whatever), almost any version of Fedora/RedHat/Centos, *SUSE, Mandriva and of course Debian (as per my personal opinion it’s the best one).

What is .docx actually? It’s Microsoft’s file format representing word processor documents and named OpenXML (as an attempt to create open and free international standard). Today .docx is default format for Microsoft’s word processor Word.

There are myriads of online converters between OpenXML and OpenOffice formats including .docx, .xlsx, .odt and many etc but sometimes it’s much more better to just open received .docx file in Linux offline (if there is temporarily no Internet connection or for security/private reasons etc).

So, just download the following package to certain directory like /usr/src, here are the commands to do it:

1. cd /usr/src
2. sudo wget http://blog.mypapit.net/imej/odf_filter.tar.bz2

The next step is to unpack the contents of the archive (.tar.bz2 is definitely well compressed file) and copy 3 files to OpenOffice’s system directories:

3. sudo tar -xvjf odf_filter.tar.bz2
4. sudo cp OdfConverter /usr/lib/openoffice/program/

5. sudo cp MOOXTypeDetection.xcu /usr/lib/openoffice/share/registry/modules/org/openoffice/TypeDetection/Types/
6. sudo cp MOOXFilter_cpp.xcu /usr/lib/openoffice/share/registry/modules/org/openoffice/TypeDetection/Filter/

As you can see from picture below now it’s possible to natively open .docx files in openoffice under Linux. Of course such “native” support may imply some artefacts in opened files due to file formats incompatibility so it’s also a good option to ask your friends to convert .docs into .pdf before sending you :)

openoffice openxml .docx

P.S. Thanks to guys from mypapit.

P.S. Here are several online converters .doc(x) <-> .odf <-> .pdf:

1. ZAMZAR (possibly the best converter), 2. http://docx-converter.com/.

Try Google Chrome in Linux

There is still no native Linux support of newly unveiled browser Google Chrome but guys from CodeWeavers prepared the port of Chromium (official name of Google Chome for Linux). This staff is already available for downloading as DEB packages for Ubuntu (32-bit and 64-bit), as RPM for RedHat, Fedora, CentOS etc. as well as self installable script for any other Linux distribution.

Well, after quick testings there are no doubts that it is not a good option if you wish to have quick and stable alternative for Firefox… But of course it is good for evaluation purposes or for those people who CAN’T wait for official release of Chrome for Linux :) Certainly the port is based on Windows copy run by Wine (don’t forget to upgrade it). Actually CodeWeavers says that this is just a proof of concept, for fun, and to showcase what Wine can do.
