    Penetration Testing with Kali Linux – Online Course Update

    Over a year ago, when we first sat down and began on what would become Kali Linux, we realized that with all the major changes, we would also need to update our flagship course, Penetration Testing with BackTrack (PWB), to be inline with Kali Linux. With the release of Kali, we ensured that we mentioned the impact this would have on PWB and that an update to the course was in the works.

    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

    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 DOM XSS 0day – Not fixed yet!

    After discussing the recent Yahoo DOM XSS with Shahin from, 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.

    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.

    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

    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 personell. The proxmark3 seemed liked an overkill and not particularly fast at reading em4x tags so we figured we’de try hooking up our RoboticsConnection RFID reader to a Teensy and see if we could make them play nicely together.
