ERNW @ HAXPO 2015

There are lots of interesting places to visit in Amsterdam, but if you are there between the 26th and the 29th of May, then our booth at HAXPO exhibition should be your main destination.

HAXPO is a great exhibition, where you can become up-to-date with the latest security technologies, attend various workshops and get in touch with more than 35 IT and information security companies. It will take place in the beautiful historical building “Beurs van Berlage” in the center of Amsterdam. As usual, ERNW will take part in HAXPO. We will be waiting for you in the Community Village section (booth NL-018). Come visit and get to know more about us. You are invited to take our hacking challenges, where the levels of complexity vary from beginners to advanced. Furthermore, we will bring our KNX hacking suitcase!

How to Get a BaseStation

In our talks in the past we showed what might be possible if an attacker gets access to backhaul and/or core network of a telecommunication provider. In a security analysts perspective this is really disgusting, but provider always will argument that those attack scenarios are not realistic.

 Because of legal restrictions we are not able to demonstrate this in practice (e.g. by breaking in into a BTS environment somewhere in the woods) but what we can do is this: building a lab.
Sometimes it is really shocking what you can buy on Ebay, right? Here we got one very interesting component: a Huawei BBU3900 BaseStation which is used by a couple of providers. Okay, it is for GSM-Rail, but the technology behind is very equal. And for 100 dollars (plus shipping) you don’t ask further questions…

Analysis of an Alarm System – Part 2/3

A few days later than planned (sorry about that), but here we go with part 2 (Part1) and the demodulation/analysis part.

Initial Analysis
To analyse a captured signal, the tool baudline seems to be the best way at the moment. So we open it with the following options and have a closer look (ContextMenu->Input->Open file):

After using the open button, you should be able to see something similar to this:

Hek.si 2015

Hey!

I attended this really nice conference in Slovenia on April 16th. It was a smaller conference, but very memorable for the people (students, IT sec professionals and managers alike) who attended.
I also had the pleasure to present on How secure am I with EMET? and Evaluating the APT armor and wanted to share the slides with you — feel free to approach me for any kind of feedback or discussion.

I’m looking forward to go to Ljubljana again! 😉

OS IPv6 Behavior in Conflicting Environments

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

SSL Tidbits at the BASTA.NET

A while a go Dominik and I gave an introductory presentation about SSL at the BASTA.NET conference, a developer-oriented event held in Darmstadt twice a year. 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.

Troopers PacketWars 2015 – Write Up

Hello Hackers!

 

 

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.

Story

 

 

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.

Analysis of an Alarm System – Part 1/3

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/ !

General Pr0ken Filesystem – Hacking IBM’s GPFS

This post is a short wrap-up of our Troopers talk about the research we did on IBM’s General Parallel File System. 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.
