Moving on to new adventures

Yesterday I have informed the people involved that effective January 1st I will be starting a new job as a full professor for “Softwaretechnik” at the University of Paderborn. In this position I plan to continue the research my group and I have been pursuing in the area of software security, but also want to broaden my research into the direction of the secure design of cyber-physical systems. In my new function I will be able to do so nicely, as at the same time I will be a member of the leadership team of the Fraunhofer-Group for Design-Methodologies of Mechatronic systems. In addition, I will be contributing to the collaborative research center On-the-fly Computing and the Software Innovation Campus Paderborn. I am very much looking forward to my new responsibilities and colleagues.

At the same time, I plan to continue the close collaborations with my dear colleagues at Darmstadt. I wish to thank everyone in Darmstadt who has contributed to making my past six years there as happy and successful as they were!

What provokes Android users into revealing private information? – Paper accepted at HICCS



In a joined work together with Nicole Eling and Prof. Buxmann from TU Darmstadt, we published a very interesting market experiment on users’ reaction to fine-grained permission requests. This work thus explores the following research questions using a self-developed mobile application:


  1. How does the precision of an information request influence users’ disclosure of personal information?
  2. Is this effect different for users with different security backgrounds?

Static Analysis Seminar (SAS) – Winter Semester

We are happy to announce that we are organizing a Static Analysis Seminar (SAS) during the Winter Semester. Interested to know more about various topics related to static analysis such as: pointer analysis, call graphs, theory behind data-flow analysis, usability of static analysis tools, and much more? Then do not hesitate to register yourself in the seminar (TUCaN ID: 20-00-0942).

More information about the seminar and the tentative schedule are available here

ESSOS final call for papers

ESSOS is accepting submissions of abstracts until the 25th and of research papers until October 2nd. We are happy to announce that both David Basin and Karsten Nohl will be presenting as invited speakers! Also, for the first time in the security community, ESSOS this year will offer a voluntary artifact evaluation! Read more in the full CFP below.

SSE Group together with Intel Security are presenting at VirusBulletin 2015 conference

A joint project together with McAfee (Intel Security) revealed very interesting insights into current Android Malware, in particular into Command and Control communications. We will be presenting our results at the VirusBulletin 2015 conference. We are also planning to publish a blog post with more concrete information, but if you are at VirusBulletin conference, feel free to join our talk on Thursday 1 October 09:00 – 09:30.

Title: We know what you did this summer: Android banking trojan exposing its sins in the cloud

Talks at the First International Workshop on Agile Secure Software Development (ASSD’15)

The workshop was an opportunity to share experiences and ideas about developing secure software using the agile processes. Achim Bruker opened the sessions with an overview of the experience of SAP in developing secure software. This was followed by a talk given by Jesus Choliz about the application of Microsoft Secure Software Development process to develop secure systems for election management. Lotfi ben Othmane continued the discussion by showing how to use the B method to detect inconsistencies of access policies in the context of incremental software development. Next, Prof. Juha Röning gave an overview about his experience in developing a security fuzzing software and their use in agile processes. The spin-off that they created out of the project was recently sold to Synopsis.

In the afternoon session, Hela Oueslati discussed the challenges of developing secure software that she found in the literature and the evaluation of the validity of these challenges with respect to the agile values and principles and security practices. She asked the participants to help her in her future empirical studies about the topic. The presentation was followed by the talk of Clemens Teichmann, who shared the experience of his team in evaluating threat modeling methods for fitness to agile development processes used by their clients.

Afterwards, the attendees discussed the common point raised in the talks: the fast feedback and adaptation that agile processes offer helps development teams reducing the cost of developing secure software. Early identification of vulnerabilities allows for fixing them fast (It is easier to fix new code). In addition, development teams can develop, early in the projects, secure programming APIs or techniques to avoid the vulnerabilities they encounter in future development.

SSE Group is presenting at Black Hat Europe 2015

At this year Black Hat Europe conference, we will talk about our Backend-As-A-Service investigation, which we published a couple of months ago.

The talk will contain a full disclosure about our investigation including details about our automatic “exploit generator”.


If you are around, feel free to join our talk and also to meet at the conference.
