"Towards Fully Automated Digital Alibis with Social Interaction";
Talk: Annual IFIP WG 11.9 International Conference on Digital Forensics, Wien; 2014-01-08 - 2014-01-10; in: "Research Advances in Digital Forensics", (2014).

Digital traces found on local hard drives as a result of online activities have become very valuable in reconstructing events in digital forensic investigations. This paper demonstrates that forged alibis can be created for online activities and social interactions. In particular, a novel, automated framework is presented that uses social interactions to create false digital alibis. The framework simulates user activity and supports communications via email as well as instant messaging using a chatbot.
The framework is evaluated by extracting forensic artifacts and
comparing them with the results obtained from a human user study.
