The training Software-Defined Radio applied to security assessments was held by Sébastien Dudek at Troopers21 and was remotely organized – like most other events – due to Covid-19. Once we were all caffeinated, we had an exciting journey through basically all things radio.Continue reading
Last week I attended ACM WiSec. Of course, only virtually. The first virtual conference I attended. Coincidentally, it was also the first conference I presented at. While the experience was quite different from a “real” conference, the organizers did a great job to make the experience as good as possible with, for example, a mattermost instance to interact with other conference participants.
In the following, I will list a few talks and papers that I either found very interesting or that generally stood out to me:Continue reading
Attackers are everywhere. They are now on the cloud too! Attacking the most popular cloud provider – AWS, requires the knowledge of how different services are setup, what defences do we need to bypass, what service attributes can be abused, where can information be leaked, how do I escalate privileges, what about monitoring solutions that may be present in the environment and so on! We try to answer these questions in our intense, hands-on scenario driven training on attacking and subsequently defending against the attacks on AWS.
As an attacker or defender, if you have ever asked any of the following questions, this training is for you:
- Is there a process to attacking the cloud or do we go after the services as and when they are discovered?
- Is SSRF the only vulnerability to access the metadata service on EC2?
- How do I use stolen AWS secret keys to attack further?
- How do I hide cover my tracks in AWS environment?
- If I can’t see a service due to security group, can I still attack it?
- How do I create better wordlists to discover and exploit S3 buckets that have uncommon names?
- Can I impersonate other users within AWS?
- Is there a way to extract secrets from AWS Lambda?
- How do I prevent credential compromise in AWS?
- How can I be sure there is no attacker already within my cloud infrastructure?
- How do I enumerate and move between accounts that are part of AWS organisations?
So, the burning question is: how does this affect Web and Desktop app security? If you want to find out, come to our training and you will experience this in a 100% hands-on fashion! 🙂
Once again, we are super excited to announce that Blackhoodie is happening at Troopers 2020. This is the 3rd time that Blackhoodie is joining with 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 woman and still feel really excited about Blackhoodie, you are welcome to apply. The registration is open now. Please hurry up and make your registration now. We will close the registration once the seats are filled up with enough quality submissions. 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!
How to register?
Blackhoodie is a free event. In order to register, go to this link and fill in your details with a brief motivation of why you would like to join Blackhoodie. We will get back to you with the selection outcome as soon as the registration is closed. Current deadline for registration is Feb 12th 2020.

16th – 17th March 2020 – Trainings
Training 1: How to (mis)use TLS? by Caroline Description: Let’s understand how TLS works and demystify some famous flaws in TLS: what went wrong ? How could we exploit it ? How was is fixed ? To answer this questions, the idea is to get our hands on networking, man-in-the-middle, rogue certificates crafting, heartbleed exploitation. Material: have a kali linux virtual machine installed. If you don’t know how to do that, I can provide an installation guide.
Training 2: Untangling C++: Reversing and Auditing C++ Binaries by Gal Zaban Description: This training is an advanced class for security researchers who want to expand their horizons and skills in reversing modern C++ binaries. C++ Binaries are full of mysteries, they have objects, inheritance, templates, vtables and many more and reverse engineering them is a task on its own. The training will explain advanced C++ reverse engineering topics including techniques and tools for dealing with research of C++ Binaries. We will start with the identification of basic C++ patterns including identifying statics, globals, arrays, etc. Than we will continue with objects and inheritance in a binary and how to represent all of those in IDA, afterward, we will study work methods and design patterns in C++. Finally, we will practice, fight and untangle deep and modern C++ programs using both static and dynamic analysis. Class outline: - C++ Reverse Engineering Intro. - Globals, Statics and Arrays - Objects + Objects Creation. - Inheritance. - Multiple Inheritance. - Understanding relationship between objects. - Virtual tables and virtual calls. - Templates. - Important Design Patterns. - IDA Pro- concepts and working methods for reverse engineering C++. - Representation of C++ objects in IDA. - Tips for creating setup and environment for C++ binaries. - Existing tools for C++. - Deep understanding of a C++ Binary's Logic. - Conclusions and wrap-up. - Suggestions for future tasks and resources to keep learning and improving C++ RE skills.
Training 3: Attacking Active Directory by Kelly Villanueva Active Directory, a service used to manage users, computers, and other objects in corporate networks,is used by almost all large corporations, making it a prime target for exploitation and abuse. Despite efforts to patch existing vulnerabilities and standardize best practices, the security exposure derived from Active Directory increases as environments become more complex, and offensive security professionals can leverage Active Directory to perform activities like lateral movement, credential theft, and reconnaissance. This workshop will provide an overview of Active Directory fundamentals, explain common attack primitives, and use open source tools to get hands-on experience attacking Active Directory.

Our workshop “TLS in the enterprise” was held for the first time at Troopers 2018 and was our special contribution to the IT Security world to increase the usage of TLS and point out the pitfalls, when switching to TLS.
But time is changing and TLS is a kind of standard nowadays, at least when looking at HTTPS, but there are still a lot of things to do regarding other protocols like
- SMTP, POP3 and IMAP
- SIP and RTP
- SSL based VPNs
just to name a few ;-). We will cover that in our training too, but the most important new stuff will be Post Quantum Security and how it will affect the future of encryption. We will talk about crypto algorithms and which of them can still be used in the future, we will talk about timelines and preparation (including the actual state of technology) like develop your master plan and we will try to clear up the myths regarding quantum computers to get your enterprise ready for the post quantum era :-).
Become aware that quantum computers will likely break most traditional public key crypto and every secret it protects. Examples for affected crypto: RSA, DH, ECC, ElGamal, PKI, digital certificates, digital signatures, VPNs, WiFi protection, smartcards, HSMs, crypto currencies, two factor authentication which relies on digital certificates (e.g. FIDO keys, Google security keys, etc.) and of course TLS.
And the quantum computers are not that far away, as the following timeline proves:
- 1998: first working quantum computer
- 2016: Google develops quantum computer
- 2017: D-Waves announces the commercial availability of the D-Wave 2000Q™ quantum computer
- 2017: IBM and Microsoft announces quantum computers
- 2018: several quantum microprocessors available
- 2019: likely over 100 quantum computers available
hmm, you are afraid now? No ;-)! You are curious? You got the point, it’s time to get prepared. The early bird catches the worm (which btw. is also true for getting your Troopers ticket and workshop seat 😉 ) the NSA said, and it moved to post-quantum in January 2016.
So to satisfy your curiosity, see you at our workshop “TLS in the enterprise” at Troopers 2020.

Containerization dominates the market nowadays. Fancy buzzwords like continuous integration/deployment/delivery, microservices, containers, DevOps are floating around, but what do they mean? What benefits do they offer compared to the old dogmas? You’re gonna find out in our training!
We are going to start with the basics of Docker, Containers and DevOps, but soon you’ll end up with your own applications running inside containers with the images residing in your own registry. Of course, following the microservices approach, and the second day hasn’t even started.After the fundamental topics of containerization are understood, you’re going to create and operate your own Kubernetes cluster. A lot of fun and challenging exercises lie ahead, to give you hands-on experience with all the technologies.
We at ERNW have not only security written on our banner, it is a mindset we share. Therefore, be prepared to get knee deep into security in regards of the discussed technologies. We will tackle the security aspects from the bottom-up, what Containerization tools can offer and how all these can be enforced and enhanced with Kubernetes to secure your clusters. From there on you are ready for the final challenge. You will jump into the role of an attacker who did compromise a Container in the cluster and escalate your privileges to Cluster Admin.
Attendees who absolved the training will have a solid understanding of container technology, especially with Docker and Kubernetes and of course the security challenges those technologies bring to the table.
So, if you’re up to a challenging training and want to get not only your feet wet with Docker and Kubernetes, you can reserve your spot for the training right here.
Thanks and kind regards,
Jan and Simon
“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 20, you can learn how to answer this question yourself!Continue reading
Some time ago I had the pleasure to speak at the BASTA! Autumn 2019 conference. There, I promised to publish my slides such that they can be used as a reference for developers and security guys like me. And with this blog post I would like to hold up to my promise.Continue reading
Windows 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:
- in-depth studies of undocumented, or poorly documented, system functionalities;
- development of performant and compatible software to monitor or extend the activities of the operating system itself; and
- analysis of security-related issues, such as persistent malware.
