Troopers16 has been over for quite a while now, but because sharing is caring, we would like to give you some more insight and share some gems that happened over the 2 days of us running a small/medium sized enterprise in mid-west Russia as part of the well received FishBowl side story.
Hell Yeah, show me

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. (more…)
At the second day of the TROOPERS16 conference an interesting talk about Advanced Persistent Threats took place from Marion Marschalek and Raphaël Vinot. Marion Marschalek is a Security Researcher, focusing on the analysis of emerging threats and exploring novel methods of threat detection. Marion started her career within the anti-virus industry and also worked on advanced threat protection systems where she built a thorough understanding of how threats and protection systems work and how both occasionally fail.

In this article, I want to provide a concise sum-up of the (to me) most interesting talks of this year’s DFRWS EU (http://www.dfrws.org/2016eu/).
Eoghan Casey, one of most famous pioneers in digital forensics, and David-Olivier Jaquet-Chiffelle, professor in police science at University of Lausanne, gave a keynote that emphasized the need for theoretical fundamental basis research in the field of digital forensics, which I fully agreed on, as this was exactly what I addressed in some of my former research.
Michael Cohen and Arkadiusz Socala received the best paper award for their work “Automatic Profile generation for live Linux Memory analysis“, which was indeed very interesting and the article is worth reading.

We just presented our Paper “Generic RAID Reassembly using Block-Level Entropy” at the DFRWS EU 2016 digital forensics conference (http://www.dfrws.org/). The article is about a new approach that we developed for forensic RAID recovery. Our technique calculates block-wise entropy all over the disks and uses generic heuristics on those to detect all the relevant RAID parameters such as stripe size, stripe map, disk order, and RAID type, that are needed to reassemble the RAID and make the data accessible again for forensic investigations (or just for data recovery).
We developed an open source implementation of our approach that is freely available at https://www1.cs.fau.de/content/forensic-raid-recovery/. The tool is able to recover RAID 0, RAID 1 and RAID 5 volumes from the single disks or disk images.
It is also able to recover a missing or failed disk in case of RAID 5 systems from the RAID redundancy information.

Troopers is (unfortunately) over. It was a blast (but I may be biased ;-))! After things have settled, I want to take the opportunity to reflect my thoughts and impressions on the IPv6-only WiFi we had deployed during the conference. To make sure that everybody is on the same page let’s start at the beginning.
In the last couple of years we had provided Dual-Stack connectivity on the main “Troopers” SSID but also had an additional IPv6-only SSID. This year we decided to spice things up and made the “Troopers“ SSID IPv6-only (with NAT64) while providing Dual-Stack connectivity on the “Legacy“ SSID. We wanted to get a feeling how many clients and applications can work properly in an IPv6-only environment. We intentionally didn’t announce it vastly beforehand, hoping that attendees would just connect to the main SSID without noticing anything. We were aware that some applications might expose issues but, as I said , we wanted to get a feeling to which degree problems actually occured. (more…)

some of you may have seen my last blog post about the preparation of the Troopers network. Today I want to give you a little teaser on what to expect for the talk I will present during the IPv6 Security Summit. As the title implies, it’s not only about building a secure IPv6 WiFi, but also a reliable one. One might think that there aren’t many differences in comparison to IPv4, but the heavy reliance on multicast of IPv6 does have implications for Wi-Fi networks in general. (more…)
Welcome to Brazil!
“Welcome to Brazil”, I think, turned to being the most used statement during the past Hackers to Hackers Conference in Sao Paulo. It was used as the main reaction to every speech taking moment, and there were a lot of those! To honor the moments and give you a quick insight into was what going on in Sao Paulo, here is a quick summary of the overall event and our own contribution.

Last week I had the pleasure to attend the “escar” (Embedded Security in Cars) conference in Cologne, Germany.
Arriving late Tuesday, I had the chance to get a rich breakfast before joining the con in the hotel Dorint at Cologne’s famous place the Heumarkt. Unfortunately I had to deal with two stumbling blocks on my way to the Dobrint: The magnetic sensor of my mobile which went crazy (no compass) and – the date. 11th of November in Cologne means just one thing – carneval! The whole city was just in a state of exception. Everybody on my way to the venue seemed to be drinking or beeing already drunk – at 9am! 😉
Being a little late, I went straight to the room after registration. As there was only one track to follow you could not miss any talk – nice thing!
After we were welcomed by the hosts, and the first talk started.
“Green Lights Forever: Analyzing the Security of Traffic Infrastructure” by Allen Hillaker
The con’s first talk was presented by Allen Hillaker. He was speaking about the security of mostly wireless traffic lights and their infrastructure in the US.
Allen presented the design of a typical traffic intersection which is connected via a radio to the road agency. He also described what happens, when a malfunction is triggered and the malfunction management unit sets the traffic lights to a well known (safe) state.
The traffic lights usually operate at 900MHz or 5.8GHz using a protocol similar to 802.11 (Wifi) without strong safety. They gathered access to the networks by using same model radio the systems at the intersections were using. As possible attacks Denial of Service, the change of the traffic lights’ timings and individual light control were named. To mitigate this, he suggested to use WPA, not broadcasting SSIDs, the use of firewalls, firmware updates and – of course – changing the default credentials. (more…)
Welcome to Dayton
In mid-October our friend Bryan Fite aka Angus Blitter invited the community for the ninth edition of Day-Con. Bryan’s annual security summit, which we regard as the sister event of TROOPERS, is a pretty good reason to visit lovely Dayton, Ohio.
And so we did… ERNW sent in five delegates. Delegates is Day-Con-speak for all attendees and speakers and such a subtle choice of wording sets the tone for the whole event. People seemed to be really focused and the roundtable-like setting during the talks (see above) provided a cozy atmosphere for in-depth expert chatting.
