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.Read More
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.Read More
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.Read More
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?Read More
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.Read More
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.Read More
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.Read More
NetHunter has been actively developed for over a year now, and has undergone nothing short of a complete transformation since its last release. We’ve taken our time with v3.0, and the results are a complete overhaul of the NetHunter Android application, with a more polished interface and a fully functioning feature set.
Through the amazing NetHunter community work led by binkybear, fattire, and jmingov, we can now proudly look at NetHunter and confidently consider it to be a stable, commercial grade mobile penetration testing platform. And so, we are really excited with todays release of NetHunter 3.0 – let the games begin!Read More
When a student earns an Offensive Security certification such as the OSCP, it is a testament to the personal investment they have made as part of a commitment to excellence. Like getting a degree from a university, no matter what happens in your life from that point forward, the fact is your earned that certification and it is yours to keep. Saying this, there are some hard truths behind the path to OSCP.Read More
A couple of weeks ago, we had the opportunity to scan and map a large IP address space covering just over 3 million hosts. Our tool of choice for this was the fast and capable masscan, which is packaged in Kali. While masscan has several convenient output formats, such as binary and XML, one feature we were missing was an easy way to search our results. We quickly whipped up a little web interface that would allow us to import and search within a masscan XML output file. This feature proved very useful for us – as once we identified a specific vulnerable pattern on a machine, we could easily cross reference this pattern with over the millions of discovered hosts in our database.Read More
With Kali 2.0 now released, we wanted to share a few post install procedures we find ourselves repeating over and over, in the hopes that you will find them useful as well. We’ve also slapped in some answers to common questions we’ve been getting. Here is our top 10 list:Read More
Last years event was a rousing success, with many attendees staying all day long and working through the multiple exercises. We had such a great time, we wanted to do it again. This is a great chance to get hands on with Kali 2.0, learning the cutting edge features and how to best put them to use. In this two session workshop series, we will be covering how to create your own custom Kali ISO that is tweaked and modified to exactly fit your needs. This will be followed up in the second session with a hands-on exercise of deploying Kali on USB sticks so that it contains several persistent storage profiles, both regular and encrypted – including the LUKS nuke feature.Read More
New Features in the Exploit Database
Over the past 6 years, we have been maintaining and updating the Exploit Database on a daily basis, which now boasts over 35,000 exploits. While we constantly work on improving our back-end and entry quality. Over the years there haven’t really been any updates to the front-end, which has traditionally stayed ominously dark and foreboding. As you may have already seen this changed about two weeks ago, with the introduction of the new and improved Exploit Database website.Read More
Kali Linux Features
Here at Offensive Security, we tend to use Kali Linux in unconventional ways – often making use of some really amazing features that Kali Linux has to offer. One of these interesting use-cases includes booting instances of Kali Linux Live over HTTP, directly to RAM. We realized there’s little documentation around this feature and thought we’d shed some light on it so others may enjoy this feature as well.
Booting Kali Over HTTP – Overview
The basic premise involves using the Kali Live kernel and initrd for booting,Read More
