PwnieScripts for Pwnie Express
The Pwnie Express (PwnPlug) is a purpose-built penetration testing device in a plug form factor. A key feature is its ability to exfiltrate from a network and connect back to your SSH server using HTTP, SSL, ICMP or DNS tunnels. Check out my tutorial on how to hack your Pwnie to make untraceable reverse SSH connections over Tor.
There are a number of steps required to set up the computer on which the Pwnie’s reverse SSH connections will be received (setting up the listeners). To simplify and automate this process, I’ve put them together into a set of very simple bash scripts. I’m hoping to turn two of these into a proper init.d script, but haven’t yet had the time. The PwnieScripts set contains the following five bash scripts, and are designed to be used on BackTrack 5 (although they can easily be adapted to work on any other distro):
- pwnsetup.sh: Automates the Pwnie Express setup process by enabling SSHD, generating SSH keys, creating a ‘pwnplug’ user, installing HTTPTunnel, generating an SSL certificate, configuring stunnel, and configuring DNS2TCP.
- pwnstart.sh: Kills any existing listeners, and then starts SSHD as well as new HTTPTunnel, stunnel (SSL tunnel), DNS2TCP (DNS tunnel) and ptunnel (ICMP tunnel) listeners.
- pwnwatch.sh: One-line script to monitor netstat for incoming connections from Pwnie Express.
- pwnconnect.sh: aka. the Lazy Script – initiates an SSH connection to the first available established connection from Pwnie Express, so you don’t have to check which ones are active. It’ll use the more secure/relible ones first (SSL, HTTP) where available. Use the -t flag to only connect over Tor.
- pwnstop.sh: Kills all existing HTTPTunnel, stunnel, DNS2TCP and ptunnel listener processses.

[Changelog]
v0.1: Initial release.
Fwknop in BackTrack 5 Repository
Just a quick update to say that fwknop (Single Packet Authorization tool) has made it into the BackTrack 5 repository. Although it’s not installed by default, it’s a few keystrokes away, and can be installed by typing the following into the terminal:
apt-get install fwknop-client
apt-get install fwknop-server (if you want to use the server on your BackTrack install)
Note that it’s still version 1.9.12 of the Perl implementation, as the the C++ port (v 2.0) is still in the Release Candidate stage. Those of you who have been meaning to experiment with Single Packet Authorization and have already downloaded BT5, now’s a good time to install fwknop and give it a try! When installing fwknop-server it brings up an ultra-simple config screen that allows you to set up your initial passphrase.

BackTrack 5 “Revolution” Released
The most popular security and penetration testing Linux distribution has been updated once again, this time built from scratch! BackTrack 5, codenamed “Revolution”, is based on Ubuntu Lucid LTS with kernel 2.6.38, and brings with it full 32 and 64-bit support, an ARM-compatible image, forensics and stealth modes, KDE (4.6) and Gnome (2.6) desktop environments, and (allegedly) over 350 updated security tools including Metasploit 3.7.0. Best of all it’s “aligned with industry methodologies”! Whatever that means ;)
It appears BackTrack 5 will only be available torrents for the time being. The torrents are available in the following flavours: Gnome ISO (32bit, 64bit, ARM img), Gnome 32-bit VMware Image, KDE ISO (32bit, 64bit). Here’s the BackTrack downloads page. Those of you wondering which flavour to get between Gnome and KDE, it’s largely dependent on one’s taste, but the BackTrack guys appear to be favouring Gnome (which was the default Ubuntu graphics environment). If you have no idea what to get, then grab the Gnome 32-bit ISO (or VMware image) using the links above. I recommend Transmission (Mac) or uTorrent (Mac/PC) for BitTorrent clients. For anyone who hasn’t used BT before, the default username and password is root/toor.
BackTrack is a great tool for network security specialists and penetration testers, but it’s an even more valuable resource for people looking at learning more about application and network security (and Linux). Although I do have an Ubuntu install, I tend to use BackTrack more often due to the convenience (when I’m not using OSX that is ;).
It’s not possible to upgrade from BT4r2 to BT5, so those of you with installations of BackTrack 4 will need to reinstall (or download the new VM).
Check out their shiny promotional video below!
[Updated] BackTrack 5 R2 is now available, and brings a new kernel and 42 new tools. You can update your existing BT5 (R1) installation by running:
echo “deb http://updates.repository.backtrack-linux.org revolution main microverse non-free testing” >> /etc/apt/sources.list
apt-get update
apt-get dist-upgrade
BackTrack 5 “Revolution” in Development (Screenshots)
Click to enlarge
BackTrack 5 – codenamed “Revolution” – is currently under development, and the team is working on updating both system and tools. At the moment it’s running a 2.6.38-rc5 kernel, improved wireless drivers, and a new KDE 4 theme is being put together.
An initial release won’t be available for at least a couple months. If you have any requests or recommendations, now’s the time to make them on the BackTrack forums.
Here are a few teaser screenshots of BT5.
[Updated 10/5/2011] BackTrack 5 is out!
BackTrack 4 r2 “Nemesis” Released
[Update 10/5/2011] BT4r2 is now superceded by the new and improved BackTrack 5!
BackTrack 4 r2 (codename “Nemesis”) has been released and brings a number of updates aimed at improving “desktop responsiveness, better hardware support, broader wireless card support, streamlined work environment”.
Updates include an updated kernel (2.6.35.8) with improved wireless support, USB 3.0, faster responsiveness, pruned and new packages, and a new BackTrack wiki for more documentation and support.
Users with existing BT4 installs/VMs can simply perform an update using:
apt-get update && apt-get dist-upgrade
BackTrack 4 r2 is available as a 2GB ISO, or 2.4GB VMWare image, on the downloads page (the BT4 download links appear to have been removed in favour of BT5).
