This year we had some excellent submissions for TelcoSecDay. Here are the first four confirmed speakers who are going to talk about the below mentioned topics:
A look at the design of the currently deployed signalling protocols for core networks, both SS7 and Diameter (legacy and LTE). Peculiar quirks and how the design has lead to the industry sometimes failing to adhere to its own standards.
Continue readingAs some of you might recall we’ve introduced a dedicated “Active Directory Security Track” at last year’s Troopers. For Troopers19 we’ve expanded it to two days (as the SAP Security Track was discontinued), and in the following I’ll provide a list of talks in the track.
Vincent Le Toux: You “try” to detect mimikatz
Abstract: This is 2019 and you still “try” to detect mimikatz. “Try”, because after many years, this post exploitation tool continues to be successful.
As a contributor to mimikatz and also a blue team guy, I’m asking myself why antivirus vendors are unable to catch it after many years.
How can a tool be blocked if nobody does not know what this tool is doing? Because surprisingly, it is known only for credential collection but mimikatz is a lot more.
To mitigate the lack of antivirus vendor, should we buy new fancy EDR tool or try a technical approach? Apply a Framework? Rely on Compliance? Use a SIEM to collect logs and apply correlation? In sumarry, can we detect mimikatz?
In this presentation we will try to understand why mimikatz has such power and especially some weakness related to credential gathering and active directory will be exposed.
“If it’s a thing, then there’s an app for it!”…We trust mobile apps to process our bank transactions, handle our private data and set us up on romantic dates. However, few of us care to wonder,”How (in)secure can these apps be?” Well… at Troopers 19, you can learn how to answer this question yourself!
In our 2 day long “Hacking mobile applications” workshop, we teach how to find security vulnerabilities in mobile apps, exploit them and defend against them. We start from scratch, therefore no prior experience in hacking or developing mobile apps is required. Whether you want to learn how to pentest mobile apps, you are an app developer that fancies to secure his/her apps, or just curios, our workshop is a jumpstart to your goal.
Continue readingWindows 10 is one of the most commonly deployed operating systems at this time. Knowledge about its components and internal working principles is highly beneficial. Among other things, such a knowledge enables:
The “Insight into Windows Internals” training offered at TROOPERS’19 delivers knowledge on the core components and inner working principles of Windows 10. For example, the training provides knowledge on how Windows 10 uses virtualization to isolate security-critical functionalities from attackers that have managed to compromise the system. The training includes a variety of practical exercises allowing attendees to observe first-hand the operation of Windows 10.
Continue readingHi there,
like in recent years the popular Hacking 101 workshop will take place on TROOPERS19, too! The workshop will give you an insight into the hacking techniques required for penetration testing. These techniques will cover various topics:
…and more!
During this workshop you will learn, step by step, a testing methodology that applies to the majority of scenarios. So imagine you have to assess the security of a system running on the Internet. How would you start? First, you need a good understanding of the target, including running services or related systems. Just scanning the target’s IP address will most likely not reveal all relevant information you can get. In the information gathering step, you will learn where you could find more relevant information than just a list of open ports. A brief understanding of the target and it’s related systems/services/applications will make scanning and identifying vulnerabilities a lot easier and more effective. Then, the last step will be the exploitation of the identified vulnerabilities, with the ultimate aim to get access to the target system and pivot to other, probably internal, systems and resources.
Continue readingOnce again Troopers will have its Windows & Linux Binary Exploitation workshop. Its main focus are the ever-present stack-based buffer overflows still found in software today (e.g. CVE-2018-5002, CVE-2018-1459, and CVE-2018-12897) and their differences with regard to exploitation on Windows and Linux systems. If you ever wanted to know the details of the exploit development process for these systems then this workshop is for you.
After initial exercises involving the exploitation of classic stack-based buffer overflows, modern defense mechanism such as Stack Cookies, DEP, and ASLR are presented and analyzed for weaknesses. The participants will learn how these defense mechanisms can be bypassed and will develop exploits targeting real world applications such as the Foxit Reader Plugin for Firefox, Wireshark, and nginx.
Continue reading“Credential Theft” or “Credential Reuse” attack techniques are the biggest known threats to Active Directory environments. This can be attributed to significant advances in and broad distribution of attack and reconnaissance tools such as mimikatz or Bloodhound. This means that after the first system in an environment is compromised it often takes less than 48 hours for a complete compromise of an Active Directory but unfortunately typically 8 to 9 months until the attack is discovered.
Continue readingIn the last couple of months we participated in an increasing count of customer projects following current trends of agile software development approaches and corresponding toolstacks. Especially the terms Continuous Integration and Continuous Delivery kept (and still keep) popping up on every corner. The frameworks and processes behind those two hypes aid developing software at higher quality in shorter release cycles. This is especially relevant since end consumers nowadays expect fast releases including the newest features. If companies neglect this demand, competitors might take advantage of their better time-to-market which might result in increased market share and -dominance. A lot of changes are happening in the space of CI/CD. Existing tools become more mature, gaining increased attention, and new ones are appearing every month including better ways of integrating them into existing or new processes. Companies benefit from more choices, increased flexibility, and faster integration into existing company policies.
Continue readingWe are going to have a Blackhoodie event at Troopers 2019 on March 18th and 19th in Heidelberg. With a very exciting event last year, we have decided to roll it once again during Troopers.
As always, one of the main motivation for Blackhoodie is bringing more women into reversing and other core security topics. So we would like to see more women apply to the training slots. However, if you are not a women and still feel really excited about Blackhoodie, you are welcome to apply. We do have a very limited number of seats at this training site. So we apologize in advance if we can’t accommodate everyone, even though we wish we could! Please apply before “February 10th” and we will contact you regarding next steps.
Continue readingDocker has become the go-to technology in enterprise- and DevOps contexts. Yet, before mastering a skill, there is the thumb rule: one must learn the basics to have solid fundament before building a house on top.
Simon and I start from the very beginning. We introduce you to the fundamental concepts of containers starting at process isolation and extending our tour to the whole ecosystem of Docker and further associated technologies. We will cover Docker, microservices, containers, DevOps, continuous integration/deployment/delivery – all those fancy buzzwords that can be read in the context of modern software development methodologies.
