Kali NetHunter 1.2 Released! Kali NetHunter 1.2 is fresh out, with a whole bunch of improvements, bug fixes….and yes, Android Lollipop support. This means that NetHunter now supports the Nexus6 and Nexus 9 devices too! This is awesome news to all those who have bought these new Nexus devices and…
With the advent of smaller, faster ARM hardware such as the new Raspberry Pi 2 (which now has a Kali image built for it), we’ve been seeing more and more use of these small devices as “throw-away hackboxes“. While this might be a new and novel technology, there’s one major drawback to this concept – and that is the confidentiality of the data stored on the device itself. Most of the setups we’ve seen do little to protect the sensitive information saved on the SD cards of these little computers.
One of the markings of the 1.0.7 Kali release was the introduction of Kali Live USB LUKS encrypted persistent storage, on which we further elaborated in one of our previous blog posts. However, we’re not done yet with USB persistent storage as more features in Kali remain to be explored.
Offsec students go through hell. They endure levels of stress and frustration beyond what is considered normal, and we at Offsec appreciate this. So much in fact, that we’ve dedicated the following song to anyone who’s taken an Offsec course, and tried harder!
With the opening shots of 2015 fired, we are happy to make some announcements in the NetHunter arena! One of the things that excite us the most about Kali Linux is how our Kali projects always end up being greater than the sum of their parts. This is most evident in our Kali NetHunter Project – the first open source Android based penetration testing platform for Nexus and OnePlus devices. Wait, OnePlus phones? Yes! Our new NetHunter v1.1 release brings with it some great news – and so we begin.
We at Offensive Security would like to thank all of our students, customers, and friends for a wonderful 2014. Its been a busy but productive year, with major upgrades to Kali Linux, the release of Kali NetHunter, the public launch of the hosted virtual labs, the first ever Kali Linux Dojo, upgrades to our student labs, lots of interesting R&D, a bunch of 0-days and a number of other accomplishments. We enjoyed the journey with all of you and here is to a fun and productive 2015! We wanted to thank you with this video we produced for all y’all.
For the past few months, we have been quietly beta testing and perfecting our new “Offensive Security Penetration Testing Labs”, or as we fondly call it, the “Offsec Playground”. Today, we are proud to unveil our hosted penetration testing labs – a safe virtual network environment designed to be attacked and penetrated as a means of learning and sharpening your penetration testing skills. The new design of the “Offsec Playground” includes multiple interconnected subnets with a wide array of modern operating systems, including Active Directory domains, Citrix systems, corporate Antivirus solutions as well as Intrusion Prevention Systems which attackers must learn to cope with.
The Kali Linux NetHunter platform has many hidden features which we still haven’t brought to light. One of them is the DriveDroid application and patch set, which have been implemented in NetHunter since v1.0.2. This tool allows us to have NetHunter emulate a bootable ISO or USB, using images of our choosing. That’s right, you can use NetHunter as a boot device which holds a library of bootable ISOs and images…And so we begin:
Several weeks ago a request in the Kali forums prompted us to look at the integration of the Adafruit 2.8in TFT touch screen for Kali Linux. A few weeks and much less hair later, we are happy to announce the availability of this image in our Offensive Security custom Kali images section.
Last week Microsoft released EMET 5.1 to address some compatibility issues and strengthen mitigations to make them more resilient to attacks and bypasses. We, of course, were curious to see if our EMET 5.0 disarming technique has been addressed by the latest version of the toolkit.
It’s been a week since our release of the Kali Linux NetHunter, and the feedback is amazing. A NetHunter community has sprung up from nowhere, and the forums and github pages are really active. We’re completely stoked about this community response, and are eager to see it grow. After an intense week of community testing and a slew of bugfixes (including shellshock), we thought it would be a good opportunity to release a NetHunter update. Please welcome NetHunter 1.0.2.
In our previous Disarming Emet 4.x blog post, we demonstrated how to disarm the ROP mitigations introduced in EMET 4.x by abusing a global variable in the .data section located at a static offset. A general overview of the EMET 5 technical preview has been recently published here.
In a recent engagement, we had the opportunity to audit a leading Antivirus Endpoint Protection solution, where we found a multitude of vulnerabilities. Some of these made it to CERT, while others have been scheduled for review during our upcoming AWE course at Black Hat 2014, Las Vegas. Ironically, the same software that was meant to protect the organization under review was the reason for its compromise.
With the emergence of recent Internet Explorer Vulnerabilities, we’ve been seeing a trend of EMET recommendations as a path to increasing application security. A layered defense is always helpful as it increases the obstacles in the path of an attacker. However, we were wondering how much does it really benefit? How much harder does an attacker have to work to bypass these additional protections? With that in mind, we started a deep dive into EMET.
