Cloud services and cloud storage solutions are special challenges in digital forensic investigations. Cloud services allow their users, with relatively little technical knowledge, store, manage and share content with others. At the same time investigators are faced with a wide range of technical, legal and organizational issues. Unfortunately, evid...

SQLite is, without doubt, the most widely used database systemworldwide at the moment. The single file database system is used, among other things, in operating systems for cell phones, such as Android, iOS or Symbian OS. On a typical smartphone, we usually find several hundred SQLite databases used by a wide variety of apps. Due to its widespread...

Java Serialization is a popular technique for storing object states in the Java programming language. In the field of mobile forensics, we come across such artefacts. App developers very often resort to this technique to make their application state persistent. Serialization is also used when transferring data over a network between two Java applic...

This open access book summarizes knowledge about several file systems and file formats commonly used in mobile devices. In addition to the fundamental description of the formats, there are hints about the forensic value of possible artefacts, along with an outline of tools that can decode the relevant data. The book is organized into two distinct...

The complexity and constant changes in mobile forensics require special training of investigators with datasets that are as realistic as possible. Even today, the generation of training data is almost exclusively done manually. This paper presents a novel open-source framework called AutoPoD-Mobile. The framework supports the creation of case-based...

Mobile forensics today is an essential part of nearly every criminal investigation. This contribution tries to shed light on the question, to which extent mobile forensics has reached its zenith. Moreover, is it turned out whether we are heading for a crisis in the future? In this context, a literature survey is presented that attempts to identify...

The digital transformation is unstoppable. The Internet of Things forms the basis of our digital information society. Growing cybercrime is one of the greatest challenges in this context. Targeted and complex cyberattacks on converged network infrastructures require innovative detection strategies to detect and classify multi-level malware and thei...

Auch in kleineren und mittelständigen Unternehmen werden industrielle Steuerungssysteme eingesetzt die auch in diesen Unternehmen immer weiter in das Unternehmensnetzwerk integriert werden. Der Sicherheitsaspekt darf dabei nicht vernachlässigt werden. Besonders kleine und mittelständige Unternehmen brauchen Lösung, die kostengünstige und ohne große...

Forensic analysis and evidence collection for web browser activity is a recurring problem in digital investigation. It is not unusual for a suspect to cover his traces. Accordingly, the recovery of previously deleted data such as web cookies and browser history are important. Fortunately, many browsers and thousands of apps used the same database s...

A number of standards identified previously provide a background to cover the current needs of the practitioners working in the area of digital forensics. However, some elements of the chain of custody in mobile forensics may be missed by standardisation, underrepresented or not covered adequately. This report outlines the standardisation gaps in m...

The objective of the present document is to analyse the status of current standardisation in mobile forensics and to point towards actions that can increase its effectiveness, ensure inclusion of all relevant stakeholders and their interests and improve the quality of mobile forensics processes and procedures. Further objective of the document is t...

Advertising networks bring companies together that run advertisements on websites or within apps. Targeting capabilities of the advertisers have increased drastically over the last years due to the availability user data and advances in data science: whether users log on to social networks or use a mobile app, they leave their traces everywhere and...

In the recent past, smart speakers and personal assistants like Alexa have been used as evidence in different criminal cases. With more than 6 million Echo devices in 2019 worldwide, there is a good chance for the constantly active devices to record criminal behavior. That is reason enough to take a closer look at the subject. This article discusse...

How can Android applications be examined for malicious behavior in a quick and easy manner? Is the process of analysis automatable? Can the results be categorized in an easy way? The growing number of mobile malware for Android and their increasingly complex structures and intelligent concealment techniques are bringing investigative agencies to th...

Der vorliegende Bericht fasst die Ergebnisse eines im Auftrag mit dem MDR durchgeführten Projektes zusammen. Es sollte die Frage geklärt werden, inwieweit Anforderungen der Datensicherheit und des Datenschutzes bei den Wahlkampf-Apps verschiedener Parteien Berücksichtigung finden. Hierfür wurden insgesamt 3 Apps von den Parteien CDU, SPD, die Grüne...

Information technology (IT) has become an integral part of production and manufacturing networks as well as critical infrastructures in the context of the fourth industrial revolution. Standard IT merges with components of factory automation and process control systems. The increasing digitization and the rise of intelligent networking opens up eno...

IT-Sicherheit und Industrie 4.0 – ein unterschätztes Thema? - Die Präsentation beschäftigt sich mit dem Thema IT-Sicherheit von industriellen Prozessen und stellt einen Ansatz vor, der im Rahmen des Projekt 3SAFE entwickelt wurde.

Der Vortrag beleuchtet die Nachverfolgung von Transaktionen im Bitcoin-Netzwerk.

Der vorliegenden Beitrag beschäftigt sich mit Vorgehensweisen zur Sicherung und Verfolgung digitaler Spuren. Wie sich zeigt, sind die Prinzipien der klassischen Forensik auch auf digitale Tatorte anwendbar und behalten im Cyberspace ihre Gültigkeit. Ausgehend von unterschiedlichen Tatorten, werden wesentlichen Schritte der Spurensicherung und Verfo...

Keynote im Rahmen der Sächsische Industrie- und Technologiemesse in Chemnitz zum Thema IT-Sicherheit im verarbeitenden Gewerbe.

Zusammenfassung Die Parallelisierung von Anwendungen, d.h. das Zerlegen eines Anwendungsproblems in Teilprobleme, die von mehreren Prozessen getrennt bearbeitet werden können, wird in der Verteilten Künstlichen Intelligenz ebenso wie in der Simulationstechnik seit vielen Jahren diskutiert. Innerhalb der VKI sind die Forscher vorrangig an flexiblen...

Research on systems of autonomous agents, called multiagent systems (MAS), has received much interest in the domain of (distributed) artificial intelligence in recent years. MAS are most suitable for the development of distributed applications within an uncertain and dynamically changing environment (Logan 2005). For validation of such systems agen...

Agent-based simulation (ABS) is a paradigm which has received much attention within the last years. For enabling industrial use of ABS scalable solutions are required which can be executed on a distributed computing architecture. Such solutions must be capable of simulating complex models with hundreds or more complex deliberative agents with reall...

In this paper we describe a time management approach to distributed agent-based simulation. We propose a new time management policy by joining optimistic synchronization techniques and domain-specific knowledge based on agent communication protocols. With respect to our experimental results, we assume that our approach helps to prevent too optimist...

Simulating large scale, distributed systems of autonomous decision-makers, e.g. global logistics supply networks, is a huge challenge for hardware and software infrastructure as well as managing the process of simulation. Facing this challenge, we are going to introduce an architecture for large scale grid-based simulation infrastructure to enable...
