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.
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.
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.
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?
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.
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.
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.
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…
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!
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.
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.
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.
