DFRWS EU 2016 Summary

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.

Mind The Gap – Exploit Free Whitelisting Evasion Tactics

At the Troopers 16 Casey Smith has given a talk about the gap in Application Whitelisting.

Application Whitelisting is a technique that should prevent malware and unauthorized applications from running. Broadly speaking this is implemented by deciding if an application is trusted or not before executing it. Casey’s talk gave an understanding where this whitelisiting fails down.

Towards a LangSec-aware SDLC

At the TROOPERS’15 Jacob l. Torrey held a track about LangSec-Aware Software Development Lifecycle. He talked about programming conventions and what tools can be used for enforcing the compliance. There is a lack of metrics to understand what make software more secure or less secure. His main goals was to show that LangSec has far-reaching impacts into software security and to give the audience a framework to transform the theory into practice. A SLDC should help to find bugs sooner in the development process and reduce defect rate in production thereby. A lower defect rate in production does not only improve security it also reduces costs.

Keynote #1 Troopers 2016

The first Keynote directly after the Opening by Enno Rey was held by Ben Zevenbergen. At the beginning he pointed out that he is not a very technical guy rather he specialized in Information Law and a policy advisor to the European Parliament. Before he started to dive into his Keynote he talked about some rant story’s which happened to him while trying to make his point clear on previous conferences and that he came in peace to Troopers ;).

How easy to grow robust botnet with low hanging fruits (IoT) – for free

Attila Marosi works as a Senior Threat Research at Sophos Labs in Hungary. His talk focused on vulnerable IoT devices that are exposed to the internet. His approach was to look for vulnerable devices with low cost tools and publicly available data.

He started his talk with the spoiler that he is not going to reveal any new attacks nor new techniques. But newer data are more adequate and we can see the current state of vulnerable devices connected to the internet. This means his approach was to test the state of IoT devices like Routers, NAS and so on with publicly available data.

Troopers Netmon

Hi everybody,

Christopher talked already about our WiFi Network during the IPv6 Security Summit and mentioned our monitoring system (we like to call “netmon”). As there were quite some people interested in the detailed setup and configuration, we would like to share the details with you. This year we used a widely known frontend called Grafana and as backend components InfluxDB and collectd. During Troopers the monitoring system was public reachable over IPv6 and provided statistics about Uplink Bandwidth, IP Protocol Distribution, Clients and Wireless Bands.

Generic RAID Reassembly using Block-Level Entropy

DFRWS EU 2016 Talk Forensic Raid Recovery
DFRWS EU 2016 Talk Forensic Raid Recovery

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.
