Once every few years I decide to head to Hannover and attend Hannover Messe, probably the largest industrial trade fair in Germany and apparently on of the most important in the world. As this year’s main topic was “Industrie 4.0” I simply could not resist to go out on a hunt for new and interesting (secure) smart connected magic! And trust me, I was not disappointed – here’s a few of my impressions.

SAP Security @ Troopers16
When it comes to SAP, Troopers has two events that are about Security in SAP Systems in particular. On the first day of the Troopers16 Trainings the BIZEC workshop takes place. The second event is a dedicated SAP track during the conference. Apart from these events there were of course a lot of nice folks to talk to (about SAP) 🙂 This post is a short overview about SAP security @ TROOPERS16.

TROOPERS16 offered many different speakers from around the globe. Below are three different talks from the afternoon of Day 2’s Defense and Management Track.
===
The TROOPERS16 talk “Attacking & Protecting Big Data Environments” presented the research of Birk Kauer and Matthias Luft, (ERNW) in which they showed how enterprise-grade “big data” environments, based on e.g. HortonWorks or Cloudera, comprising of components such as HDFS, Yarn, Hue, Flume, Hive, Spark, Sentry/Ranger could be attacked. These environments typically process huge amounts of data. The data is either stored in a cluster file system or streamed into clusters. The processing of these datasets are done by jobs, and these jobs can be arbitrary code execution.

Hi everyone,
I spent the last weeks traveling to Singapore and Miami to present my Xenpwn research about double fetch vulnerabilities in paravirtualized devices at Infiltrate and Syscan360. You can find my slides here. Both conferences had great organization, very technical talks and a cool audience. In the following I want to give a short recap of some of the talks I liked the most:
Sean Heelan – Automatic Root-Cause Identification for Crashing Executions (Infiltrate)
Sean Heelan talked about his work on automated root cause analysis. The goal of this research is to give a human researcher a detailed analysis of the potential root causes (in the form of violated predicates) that triggered a crash during a fuzzing run. Sean summarizes the core idea of his research much better than I would be able to in his blog post, which also contains a link to his slides. I’m always a big fan of his talks because he is one of the few peoples working in the intersection between the academic program verification community and the IT security industry.

This is a short summary of selected talks (i.e. those that I found the most interesting of those I was able to personally attend) of the GI Sicherheit 2016.
First of all, congratulations to Dr. Fabian Yamaguchi, who received an award (the GI Promotionspreis) for his PhD thesis “Pattern-Based Vulnerability Discovery“!
His work presents an “approach for identifying vulnerabilities which combines techniques from static analysis, machine learning, and graph mining to augment the analyst’s abilities rather than trying to replace her” by identifying and highlighting patterns of potential vulnerabilities in source code.
TSD 2016 – Follow Up
Thanks again for all the great talks and fruitful discussions @TSD 2016! I hope everybody had a safe trip home and enjoyed Troopers as we did. In the meantime I contacted all speakers to talk about publication of their slidesets. Some of them agreed (or already published them on their own) so I’d like to share these with you:
Alexandre De Oliveira – Assaulting IPX Diameter roaming network
Siddharth Rao – The known unknowns of SS7 and beyond.
Joao Collier de Mendonca – “rucki zucki” scanning tool
Harald Welte – Open Source Network Elements for Security Analysis of Mobile Networks
Ravi & Altaf Shaik – Don’t connect to my 4G base station: investigating info leaks in 4G basebands
Unpatchable – Living with a vulnerable implanted device
TL;DR: Marie Moe talked about security issues of medical devices, especially implantable devices like pacemakers, but not in overwhelming technological depth. She wanted to point out the necessity of intensified security research in the field of medical devices as vendors and medical personnel seem to be lacking necessary awareness of security of devices, interfaces, services, and even data privacy.”Get involved, join the cavalry” was her core message.
Lub-Dub-Lub-Dub-Lub-Dub
Marie started her talk with the sound of a repeating heartbeat. First she introduced how she came up with the topic of her talk: Marie relies on a pacemaker herself andsince she got it implanted she was curious how secure this little device might be. A minimum education of the auditorium followed including an explanation how a human heart works and what a pacemaker does.
Security Assessment of Microsoft DirectAccess
A talk about DirectAccess (an IPv6-only VPN solution) was given by our colleague Ali Hardudi during IPv6 summit. Ali has recently finished his master thesis on this topic.
The DirectAccess VPN technology was introduced by Microsoft starting from Windows server 2008. It allows users remotely, seamlessly and securely connect to their internal network resources without a need to provide user credentials, which is done using different technologies such as Windows domain group policies.

Jasper Bongertz is a Senior Technical Consultant at Airbus Defence and Space CyberSecurity. He is focusing on IT security, Incident Response and Network Forensics.
During the IPv6 summit on Troopers16 he had given a talk on anonymization IPv6 in PCAPs and presented his new tool.
Sometimes you need to share your packet capture files (PCAPs), but distributing them involves a risk of exposing the confidential information. To avoid this, you must sanitize your PCAPs. The goal of sanitization is to remove the critical details but keep enough information for the PCAP to still be useful. The original-to-sanitized ratio is based on your goals.

The first talk after the keynote on day 2 of TROOPERS was from Christopher Truncer about passive intelligence gathering and the analytics of that. Christopher Truncer (@ChrisTruncer) is a red teamer with Mandiant. He is a co-founder and current developer of the Veil-Framework, a project aimed to bridge the gap between advanced red team and penetration testing toolsets.
His talk is mainly about defending a network from different threats by collecting and analyzing metadata from different sources.
