I was invited by the Swiss IPv6 Council to give a talk on this topic yesterday. We had good conversations after the talk – thanks for the invitation!
For those interested the slides can be found here. I will happily discuss the intricacies of DHCPv6 and how to deploy it in complex environments at the upcoming IPv6 Business Conference in Zurich and in my “IPv6 in Enterprise Networks” training in Berlin.
Have a great day everybody

At that time there were quite some enthusiastic participants but recently we’ve also gotten some inquiries asking for the relevant materials. Although there’s no recording of the session, we’ve decided to put the slides here for those interested who didn’t make it to the talk.

This year’s PacketWars contest at Troopers was a blast! Under the topic of “Connected Car” the teams faced several different challenges, which we will describe (as a debriefing) here.
From the Packetmaster’s Battle Briefing:
You and your krew are “freelancers” hired to identify and neutralize an unknown
threat agent who has created weaponized software and delivered it to civilian
Connected Cars via compromised EV (Electrical Vehicle) charing stations. To make
matters worse there are indications that new strains of the malware are
appearing as the “worm” spreads from car to car. The mobile mesh network created
by the Connect Car is highly resilient, allowing the malware to spread
exponentially. Time is of the essence.
Malware analysis suggests that besides a botnet module, there is an active
CANBus injection capability. There appears to be other modules but they haven’t
been properly reversed and analyzed yet.
Introduction
This and the following two posts should serve as a step-by-step guide through
the whole process of analyzing a radio frequency black box, demodulate and
understand the data transfered and finally modulate our own data in order to
e.g. perform a brute force attacks.
The information provided and the results are immensely inspired by Michael Ossmann and the workshops he has given at our location. Visit him and his great tool HackRF at https://greatscottgadgets.com/hackrf/ !

If you are interested in all the technical details take a look at our slides or the video recording. We will also give an updated version of this talk at the PHDays conference in Moscow next month.
The IBM General Parallel File System is a distributed file system used in large scale enterprise environments, high performance clusters as well as some of the worlds largest super computers. It is considered by many in the industry to be the most feature rich and production hardened distributed file system currently available. GPFS has a long and really interesting history, going back to the Tiger Shark file system created by IBM 1993.

All articles cover a black box called IP Box, the fact that PINs can be broken and that sometimes the automatic wipe after 10 failed tries can be circumvented. Sadly, as often, the what is described but not the how……
This blog post will give you a simple overview of both the practical attacks and the vulnerabilities behind them. Although the Headings don’t quite give away the content, the post starts with a simple PIN bruteforce against iOS 7.x and then goes over to a more advanced attack on iOS 8.x and a few technical details on the “black box”.

On March 16^(th), 2015, at the Troopers IPv6 Security Summit, we finally released the SI6 Networks’ IPv6 Toolkit v2.0 (Guille). The aforementioned release is now available at the SI6 IPv6 Toolkit homepage. It is the result of over a year of work, and includes improvements in the following areas:
Increased Portability
One of the goals that the SI6 Toolkit had since its inception is that of portability. The SI6 Toolkit has supported all major BSD-derived OSes, Linux, and Mac OS for a number of years now. And this new release supports yet another new platform: OpenSolaris. We believe that besides supporting a greater user base, increased portability ultimately results in improved code quality.

This article should also serve to summarize a couple of points we’ve mentioned during our talks about MLD but which because of time constraints never make it into the main discussion. We’ve talked about other aspects of MLD in previous posts. So, have a look at those if this is a topic which you find interesting. Without further ado, let’s start for today.

After a very unpleasant Lufthansa strike (which made us arrive late in Singapore) and two intense workshop days, we were free to attend the “last” SyScan. There are few IT security conferences that have such a great reputation in the community and so we had high expectations, which were definitely not disappointed. This year had a lot of really interesting talks so I will just summarize some of the ones I liked the most.
