Ultimate Pentesting PwnBox (2013) - Utilite Pro

[mrreboot]

We’re always on the lookout for and interesting ARM hardware for Kali Linux. Whether it’s a Galaxy Note or a USB stick sized SS808, we want to see Kali run on it. You can therefore imagine our excitement, when we first laid our eyes on the Utilite pro.

Utilite Pro is a quad core ARM cortex-A9 machine with up to 4 GB of RAM, up to 512 GB mSATA SSD, HDMI and DVI-D output, dual (2x) 1GB nics, a built in wireless card and 4 USB ports. And its fanless. With those type of specs, this little beauty was unlikely to skip our radars. We wanted Kali Linux on that baby, real bad.

We took this opportunity to create and publish the Offensive Security Kali Linux contributed ARM images, and thought we’d demonstrate the use of these scripts, and show you how to get Kali linux on the Utilite Pro. From there, the options are endless.

The Utilite Pro came with Ubuntu preinstalled. The first thing we wanted to do, is update the machines uBoot bootloader image, to allow for support of 1.8V microSD cards.

root@utilite:~# apt-get install mtd-utils
root@utilite:~# git clone https://github.com/offensive-security/kali-uboot-images.git uboot
root@utilite:~/uboot# ./cm-fx6-bootloader-update.sh

Once that was done, we whipped out our Offensive Security Trusted Contributed ARM image scripts, and let our Utilite image builder script loose. On a separate 32 bit Kali Linux machine, we set up all the pre-requisites to build our ARM image, and make sure we have at least 10GB of free space. We start with downloading and setting up the ARM cross compiler and the build scripts:

root@builder:~# git clone https://github.com/offensive-security/kali-arm-build-scripts.git

Resolving deltas: 100% (2559/2559), done.
root@builder:~#

Once that’s done, we next run the build-deps scripts, which will install all the dependencies required for the build:

root@builder:~# cd kali-arm-build-scripts/
root@builder:~/kali-arm-build-scripts# ./build-deps.sh
Reading package lists... Done
Building dependency tree      
Reading state information... Done
abootimg is already the newest version.
...

Now with everything in place, we kick off our Utilite image builder script, and go for a coffee, or six. The script requires a version parameter for the image, which is something we use to tag our ARM image versions. Once ready, you should get a *full* Kali Linux image which can then be dd’ed to a microSD card. Of course, you are encouraged to read the build script, and edit any installation parameters or packages to your needs.

Once the image is ready, you can find it in the utlite subdirectory created by the script:

root@builder:~/kali-arm-build-scripts# ls -l utilite-1.0/
total 334720
-rw-r--r-- 1 root root        63 Dec  7 23:48 kali-1.0-utilite.img.sha1sum
-rw-r--r-- 1 root root 342742176 Dec  7 23:52 kali-1.0-utilite.img.xz
-rw-r--r-- 1 root root        66 Dec  7 23:53 kali-1.0-utilite.img.xz.sha1sum
root@builder:~/kali-arm-build-scripts#

Extract the compressed image file, and dd it to the microSD card (in our case, sdb). Once done, pop the microSD card into the Utilite, and boot it up!

root@proxy:~/kali-arm-build-scripts# cd utilite-1.0/
root@proxy:~/kali-arm-build-scripts/utilite-1.0# 7z x kali-1.0-utilite.img.xz
