Abstract. Digital forensic investigators commonly use dynamic malwareanalysis methods to analyze a suspect executable found during a post-mortem analysis of the victim's computer. Unfortunately, currently proposed dynamic malware analysis methods and sandbox solutions have a number of limitations that may lead the investigators to ambiguous conclusions. In this research, the limitations of the use of current dynamic malware analysis methods in digital forensic investigations are highlighted. In addition, a method to profile dynamic kernel memory to complement currently proposed dynamic profiling techniques is proposed. The proposed method will allow investigators to automate the identification of malicious kernel objects during a post-mortem analysis of the victim's acquired memory. The method is implemented in a prototype malware analysis environment to automate the process of profiling malicious kernel objects and assist malware forensic investigation. Finally, a case study is given to demonstrate the efficacy of the proposed approach.
The popularity of Peer-to-Peer (P2P) Internet communication technologies being exploited to aid cybercrime is ever increasing. P2P systems can be used or exploited to aid in the execution of a large number of online criminal activities, e.g., copyright infringement, fraud, malware and virus distribution, botnet creation, and control. P2P technology is perhaps most famous for the unauthorised distribution of copyrighted materials since the late 1990’s, with the popularity of file-sharing programs such as Napster. In 2004, P2P traffic accounted for 80% of all Internet traffic and in 2005, specifically BitTorrent traffic accounted for over 60% of the world’s P2P bandwidth usage. This paper outlines a methodology for investigating a documented P2P network, BitTorrent, using a sample investigation for reference throughout. The sample investigation outlined was conducted on the top 100 most popular BitTorrent swarms over the course of a one week period.
