Offensive Security Penetration Test Report 2013

Penetration Test Report 2013

We are proud to release a new, updated, sample penetration test report. This report accurately reflects the types of assessments we conduct for our clients. It incorporates changes we have made over the last two years based on customer feedback, as well as reflecting many of the types of attacks we have found to be effective in multiple customer environments.

Kali Linux ISO of Doom

Kali Linux ISO of Doom

In our last blog post, we provided an example of running an unattended network installation of Kali Linux. Our scenario covered the installation of a custom Kali configuration which contained select tools required for a remote vulnerability assessment using OpenVAS and the Metasploit Framework.

Unattended installation with PXE

Kali Linux Unattended PXE Install

Our last blog post on the Kali Linux site discussed implementing some cool scenarios with Kali Linux, such as remote unattended installations, creating custom Kali Linux ISOS, and getting Kali working on funky ARM hardware. We received several emails from people asking for more information on how to implement these scenarios, so we thought we’d make a few blog posts with more detailed examples.

Kali Linux on a Galaxy Note 10.1

Kali Linux on a Galaxy Note 10.1

Here at Offsec, we love playing with hardware. Be it something like the Onity Hotel Door Unlocker, a Teensy USB HID attack payload, or RFID hacks – if it’s shiny, we like it. While we were in the last stages of developing Kali Linux, we made the effort to to get Kali working on some ARM hardware, such as the Samsung Chromebook, Odroid U2, Raspberry Pi and RK3306 devices such as the SS808, and then contributed these to the community as “Unofficial Trusted Images”, together with the Official Kali Linux downloads.

Kali Linux a new dawn has come...

Kali Linux Has Been Released!

Seven years of developing BackTrack Linux has taught us a significant amount about what we, and the security community, think a penetration testing distribution should look like. We’ve taken all of this knowledge and experience and implemented it in our “next generation” penetration testing distribution.

AWE Vienna Course: Advanced Windows Exploitation

Advanced Windows Exploitation Vienna

The Advanced Windows Exploitation (AWE) class in Vienna is coming up quick! This will be our first time teaching the class outside of the US and is the only public planned AWE this year outside of BlackHat Vegas. We have secured a beautiful facility on the 24th floor of the Millennium Tower on the Vienna waterfront, and still have a couple of seats left open. So if you are interested in coming now is the time to take action!

BackTrack Reborn - Kali Linux

BackTrack Reborn – Kali Linux

It’s been 7 years since we released our first version of BackTrack Linux, and the ride so far has been exhilarating. When the dev team started talking about BackTrack 6 (almost a year ago), each of us put on paper a few “wish list goals” that we each wanted implemented in our “next version”. It soon became evident to us that with our 4 year old development architecture, we would not be able to achieve all these new goals without a massive restructure, so, we massively restructured and “Kali” was born. We’ve also posted a Kali Linux teaser on the BackTrack Linux site – and that’s all we’ll say for now…

Yahoo XSS 0-Day

Yahoo DOM XSS 0day – Not fixed yet!

After discussing the recent Yahoo DOM XSS with Shahin from Abysssec.com, it was discovered that Yahoo’s fix is not effective as one would hope. According to Yahoo, this issue was fixed at 6:20 PM EST, Jan 7th, 2013. With little modification to the original proof of concept code written by Abysssec, it is still possible to exploit the original Yahoo vulnerability, allowing an attacker to completely take over a victim’s account. The victim has to be lured to click a link which contains malicious XSS code for the attack to succeed. This can demonstrated by the video we have created just this morning (Jan 8th, 2013) after Shahin kindly shared proof of concept code with us.

Fun with AIX Shellcode and Metasploit

Fun with AIX Shellcode and Metasploit

In one of our recent pentests, we discovered an 0day for a custom C application server running on the AIX Operating System. After debugging the crash, we discovered that the bug could lead to remote code execution and since we don’t deal very often with AIX exploitation, we decided to write an exploit for it. The first steps were accomplished pretty quickly and we successfully diverted the execution flow by jumping to a controlled buffer. At this point, we thought we could easily generate some shellcode from MSF and enjoy our remote shell.

CA ARCserve – CVE-2012-2971

CA ARCserve – CVE-2012-2971

On a recent penetration test, we encountered an installation of CA ARCserve Backup on one of the target systems that piqued our interest. Like most “good” enterprise applications, ARCserve has processes that are running as SYSTEM so naturally, we went straight to work looking for vulnerabilities.

Advanced Windows Exploitation - Vienna, Austria

AWE is Going to Vienna, Austria

Join us for a mind-blowing experience in a city known for its dynamic history and contemporary design, Vienna, Austria. For the first time in Europe we are holding our most intense live training course, Advanced Windows Exploitation (AWE). Be prepared to be challenged beyond your limits!

Onity Door Unlocker Round Two

Onity Door Unlocker, Round Two.

On one of our engagements, we figured an Onity Hotel door unlocker would be useful to us. Inspired by the James bond type setup we saw on the Spiderlabs blog post, we thought we’de try to build a small, simple and “TSA friendly” version of the Onity key unlocker. Pro Tip: Connecting a 9v battery with the wrong polarity to an Arduino Mini Pro will make pretty sparks.

Stand-Alone EM4x RFID Harvester

Stand-Alone EM4x RFID Harvester

Continuing off from our last RFID Cloning with Proxmark3 post, we wanted to build a small, portable, stand-alone EM4x RFID tag stealer. We needed an easy way of storing multiple tag IDs whilst “rubbing elbows” with company personnel. The proxmark3 seemed liked an overkill and not particularly fast at reading em4x tags so we figured we’d try hooking up our RoboticsConnection RFID reader to a Teensy and see if we could make them play nicely together.

Cloning RFID Tags with Proxmark 3

Cloning RFID Tags with Proxmark 3

Our Proxmark 3 (and antennae) finally arrived, and we thought we’d take it for a spin. It’s a great little device for physical pentests, allowing us to capture, replay and clone certain RFID tags. We started off by reading the contents of the Proxmark wiki, to understand (more or less) what we are up against. This proved to be a vitally important step, and we are thankful we had the insight to RTFM a tad bit before.

Advanced Teensy Penetration Testing Payloads

Advanced Teensy Penetration Testing Payloads

In one of our recent engagements, we had the opportunity to test the physical security of an organization. This assessment presented an excellent scenario for a USB HID attack, where an attacker would stealthily sneak into a server room, and connect a malicious USB device to a server with logged on console, thus compromising it. From here, the “Peensy” (Penetration Testing Teensy?) was born.
