TROOPERS20 Training Teaser: TLS in the Enterprise – Post Quantum Security

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

  • Jabber
  • LDAP
  • Telnet
  • SMTP, POP3 and IMAP
  • SIP and RTP
  • MySQL
  • Postgres
  • 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.

Cheers

TROOPERS20 Training Teaser: Swim with the whales – Docker, DevOps & Security in Enterprise Environments

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

TROOPERS20 Training Teaser: Insight Into Windows Internals

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.

DevSecCon19 London – How to Secure OpenShift Environments and What Happens If You Don´t

This week I was at DevSecCon in London to present my current research on Red Hat OpenShift. In this talk, I gave a brief introduction to OpenShift, demonstrated some threats that exist for such environments, and dived into different configuration issues that may affect the security of OpenShift environments. The implications of misconfigurations of such an environment have been shown in live demos.

TROOPERS20 Training Teaser: Hacking 101

Hi there,
like in recent years the popular Hacking 101 workshop will take place on TROOPERS20, too! The workshop will give you an insight into the hacking techniques required for penetration testing. These techniques will cover various topics:

  • Information gathering
  • Network scanning
  • Web application hacking
  • Low-level exploitation

…and more!

TROOPERS20 Training Teaser: Windows & Linux Binary Exploitation

We are happy to announce that TROOPERS20 will feature the 5th anniversary of the popular Windows & Linux Binary Exploitation workshop!

In this workshop, attendees will learn how to exploit those nasty stack-based buffer overflow vulnerabilities by applying the theoretical methods taught in this course to hands-on exercises. Exercises will be performed for real world (32-bit) software such as the Foxit Reader Plugin for Firefox, Wireshark, and nginx.

Dissection of an Incident – Part 2

After our last blogpost regarding Emotet and several other Emotet and Ransomware samples that we encountered, we recently stumbled across a variant belonging to the Gozi, ISFB, Dreambot respectively Ursnif family. In this blogpost, we want to share our insights from the analysis of this malware, whose malware family is mainly known for being a banking trojan that typically tries to infect browser sessions and sniff/redirect data. In particular, we are going to provide details about the first stage Word Document, the embedded JavaScript/XSL document, an in-depth runtime analysis of the downloaded executable, and some details regarding detection.

Also, with this blog post, we are releasing a Rekall plugin called pointerdetector that enumerates all exported functions from all DLLs and searches the memory for any pointer to them (essentially a search for dynamically resolved APIs). This plugin can assist in identifying dynamically resolved APIs and especially memory regions containing DLLs loaded with techniques such as reflective DLL injection. This blog post will contain some examples illustrating the usage of this plugin, as well.

If you are interested in a hands-on analysis of Incidents and malicious files, we are giving another round of our Incident Analysis workshop at Troopers20.

Windows Insight: Code integrity and WDAC

The Windows Insight repository now hosts three articles on Windows code integrity and WDAC (Windows Defender Application Control):

  • Device Guard Image Integrity: Architecture Overview (Aleksandar Milenkoski, Dominik Phillips): In this work, we present the high-level architecture of the code integrity mechanism implemented as part of Windows 10.
  • Windows Defender Application Control: Initialization (Dominik Phillips, Aleksandar Milenkoski): This work describes the process for initializing WDAC performed by the Windows loader and the kernel when Windows 10 is booted.
  • Windows Defender Application Control: Image verification (Aleksandar Milenkoski): This work discusses the workflow of WDAC for verifying images.
