I am looking forward to our newly introduced dedicated Forensic Computing Training at TR17!
We will start the first day with a detailed background briefing about Forensic Computing as a Forensic Science, Digital Evidence, and the Chain of Custody. The rest of the workshop we will follow the Order of Volatility starting with the analysis of persistent storage using file system internals and carving, as well as RAID reassembly with lots of hands-on case studies using open source tools. As a next step, we will smell the smoking gun in live forensics exercises. Depending on your preferences we will then dig a bit into memory forensics and network forensics.

TR17 Training: Crypto attacks and defenses
This is a guest blog written by Jean-Philippe Aumasson & Philipp Jovanovic about their upcoming TROOPERS17 training: Crypto attacks and defenses.
The 1-day training from last TROOPERS has become a 2-day training, featuring even more real-world attacks and defenses as well as new hands-on sessions! We’ll teach you, step by step, how to spot and exploit crypto vulnerabilities, how to use the strongest forms of state-of-the-art cryptography to secure modern systems (like IoT or mobile applications), and bring you up to speed on the latest and greatest developments in the world of cryptography, such as TLS 1.3, blockchains, and post-quantum crypto.

Hello and a Happy new Year!
There are only two and a half months left, so I’d like to publish the next two talks for TelcoSecDay 2017, taking place at 21st of March in Heidelberg. Both talks are about the security of an upcoming technology which importance will raise in near future: 5G Networks.

Woolim – Lifting the Fog on DPRK’s Latest Tablet PC
Niklaus, Manuel and me had a great time speaking about one of the latest Tablet PCs from DPRK at 33C3 this year. Our work on RedStar OS from last year revealed a nasty watermarking mechanism that can be used to track the origin and distribution path of media files in North Korea. We have seen some interesting dead code in some of RedStar’s binaries that indicated a more sophisticated mechanism to control the distribution of media files. We got hands on a Tablet PC called “Ul-lim” that implemented this advanced control mechanism.

Continue readingIPv6 Configuration Approaches for Servers
In this post I’ll discuss configuration approaches for systems which usually have been configured with “static” IP parameters in the IPv4 age/context (like servers in data centers). When it comes to IPv6 there are more options and we’ll have a look at their implications and potential advantages/disadvantages.

We had to make some tough choices regarding our TROOPERS17 Main Conference Agenda. Thank you again to everyone for submitting! The full agenda will be published later this week, but for now here are the next round of talks!

This is a guest blog written by Hanno Böck who will be running the Fuzzing with American Fuzzy Lop, Address Sanitizer and LibFuzzer at TROOPERS17.
Fuzzing is a very old technique to find bugs and vulnerabilities in software. However it has seen a new push in recent years due to vastly improved tools. The compilers gcc and clang have received Sanitizer tools that allow finding a lot of bugs like use after free errors and out of bounds reads that are otherwise very hard to find.

Continue readingPoC Con Seoul 2016
Recently I had the pleasure to join the PowerOfCommunity conference in Seoul. Florian and Felix attended the conference in the past and enjoyed it a lot, so I took the opportunity to join this year. From what I had heard the conference is highly technical, offensive security and community focused (surprise 😉 ). Boy did they deliver!
Located in a hotel next to a nice park and close to the famous Gangnam district in Seoul we came together to feel the power of community. The conference was planned for two days and offered two tracks per day. Several key talks were presented for everyone. Continue reading “PoC Con Seoul 2016”
2nd Rounds of TROOPERS17 Talks!
It is the end of the year and we are hoping it is not too hectic of a time for you all! But if it is, hopefully the announcement of our next round of TROOPERS17 talks is enough to get you in the TROOPERS (if not the holiday) spirit 🙂
Francis Alexander & Bharadwaj Machiraju: How we hacked Distributed Configuration Management Systems
With increase in necessity of distributed applications, coordination and configuration management tools for these classes of applications have popped up. These systems might pop-up occasionally during penetration tests. The major focus of this research was to find ways to abuse these systems as well as use them for getting deeper access to other systems. Continue reading “2nd Rounds of TROOPERS17 Talks!”

Even if the CFP for TelcoSecDay 2017 is officially closed, I am still getting mails in. First of all: thank you for all your great feedback! As the TelcoSecDay is a complimentary and non-public event with highly specialized topics, it only works by sharing knowledge with each other. But please keep in mind that the speaker-slots are limited and I have to make a decision at some point of time.
Anyhow, I am looking forward for a great event and I am proud to publish the first accepted talks:
