Development of a new Windows 10 KASLR Bypass (in One WinDBG Command)

Windows 10 1809 Kernel ASLR Bypass Evolution

When it is well-implemented, Kernel Address Space Layout Randomization (KASLR) makes Windows kernel exploitation extremely difficult by making it impractical to obtain the base address of a kernel driver directly. In an attempt to bypass this, researchers have historically focussed on kernel address leaks to retrieve these addresses, either through specific kernel-memory disclosure vulnerabilities or using a kernel-mode read primitive created through a kernel vulnerability like a pool overflow or a write-what-where.

AWAE Now Available Anywhere, Anytime

Our Advanced Web Attacks and Exploitation (AWAE) live training course has been one of the fastest-selling classes at various industry events for years. The Black Hat classes perennially sell out in a matter of minutes, and every year we’re snowed under by demand from security professionals wondering when we’ll offer it online. For this reason, today we’re excited to announce AWAE is now available online…

Cheating Attempts and the OSCP

Last week, an individual started to release solutions to certain challenges in the OSCP certification exam. This led to some discussion on Twitter and made it clear to us that there is a fair amount of misunderstanding about what’s on the exam, how we catch cheaters, how many people attempt to cheat, and what happens when they are discovered. In this post, we would like to shine some light on our certification process.

Offensive Security Appoints Ning Wang as CEO to Lead Organization’s Next Stage of Growth

Today we all constantly read about data breaches that could have been prevented if the impacted organization had just done what they were supposed to do. The unfortunate reality is that cyberattacks are now a matter of ‘when’ and not ‘if’ for the average enterprise. Yet the landscape is changing and protecting your environment is actually getting more challenging not less.

Cyber adversaries are more organized and talented than ever, so an effective cyber defense now requires more than just following the right processes. Today’s enterprises need defenders who perform their jobs with an adversarial mindset. While this need is becoming more acute every day, we are also presently in the midst of an enormous cybersecurity skills shortage. These two forces are diametrically opposed and there is only one way toward resolution – practical security training.

This being the case, I couldn’t be happier to join Offensive Security as the company’s next CEO.

Offensive Security Online Exam Proctoring

When we started out with our online training courses over 12 years ago, we made hard choices about the nature of our courses and certifications. We went against the grain, against the common certification standards, and came up with a unique certification model in the field – “Hands-on, practical certification”. Twelve years later, these choices have paid off. The industry as a whole has realized that most of the multiple choice, technical certifications do not necessarily guarantee a candidate’s technical level…and for many in the offensive security field, the OSCP has turned into a golden industry standard. This has been wonderful for certification holders as they find themselves actively recruited by employers due to the fact that they have proven themselves as being able to stand up to the stress of a hard, 24-hour exam – and still deliver a quality report.

The Synology Improbability

Recently, my manager purchased a Synology NAS device for me to do some backups. Since quite a few people I know use this particular NAS (including myself now), I decided to do a quick audit on it before integrating it into my lab environment. In this blog post, I will cover two different vulnerabilities patched by Synology.

Auditing the Auditor

Some time ago, we noticed some security researchers looking for critical vulnerabilities affecting “security” based products (such as antivirus) that can have a damaging impact to enterprise and desktop users. Take a stroll through the Google Project Zero bug tracker to see what we mean.

Fldbg, a Pykd script to debug FlashPlayer

A few months ago, we decided to make a new module for our Advanced Windows Exploitation class. After evaluating a few options we chose to work with an Adobe Flash 1day vulnerability originally discovered by the Google Project Zero team. Since we did not have any previous experience with Flash internals, we expected a pretty steep learning curve.

Hacking WPA Enterprise with Kali Linux

Admittedly, somewhat of a click-bait blog post title – but bear with us, it’s for a good reason. Lots of work goes on behind the scenes of Kali Linux, tools get updated every day and interesting new features are added constantly. Most of these tool updates and feature additions go unannounced, and are then discovered by inquisitive users – however this time, we had to make an exception.

A Decade of Exploit Database Data

Managing the Exploit Database is one of those ongoing tasks that ends up taking a significant amount of time and often, we don’t take the time to step back and look at the trends as they occur over time. Have there been more exploits over the years? Perhaps fewer? Is there a shift in platforms being targeted? Has the bar for exploits indeed been raised with the increase in more secure operating system protections?

What it means to be an OSCP reloaded

In our recent blog post  “What it means to be an OSCP” we asked OSCPs to share their experience of what it means to have earned this certification and we received many tales of hardship and reward. Mike Benich sent in an entry that we felt very much captured the essence of the Offensive Security mentality; that the path to OSCP is challenging, stressful, and demanding, but the results leave you with much more than technological expertise.

Kali Linux 2.1.2 ARM Releases

The time has come for yet another Kali ARM image release with new and updated images. Our collection of supported ARM hardware grows constantly with new images from Raspberry Pi 3, Banana Pi and Odroid-C2, with the latter being our first real arm64 image. We’re really excited about our new arm64 build environment and hope to see more 64bit ARM devices running Kali in the future. Feel free to visit our Kali Linux ARM downloads page to get the latest goodness.

Kali Rolling ISO of DOOM, Too.

A while back we introduced the idea of Kali Linux Customization by demonstrating the Kali Linux ISO of Doom. Our scenario covered the installation of a custom Kali configuration which contained select tools required for a remote vulnerability assessment. The customised Kali ISO would undergo an unattended autoinstall in a remote client site, and automatically connect back to our OpenVPN server over TCP port 443. The OpenVPN connection would then bridge the remote and local networks, allowing us full “layer 3” access to the internal network from our remote location. The resulting custom ISO could then be sent to the client who would just pop it into a virtual machine template, and the whole setup would happen automagically with no intervention – as depicted in the image below.
