Forensic Analysis Of A Playstation 3 Console, Scott Conrad, Greg Dorn, Philip Craiger

Publications

The Sony PlayStation 3 (PS3) is a powerful gaming console that supports Internet-related activities, local file storage and the playing of Blu-ray movies. The PS3 also allows users to partition and install a secondary operating system on the hard drive. This “desktop-like” functionality along with the encryption of the primary hard drive containing the gaming software raises significant issues related to the forensic analysis of PS3 systems. This paper discusses the PS3 architecture and behavior, and provides recommendations for conducting forensic investigations of PS3 systems.

Computer Forensic Functions Testing: Media Preparation, Write Protection And Verification, Yinghua Guo, Jill Slay

Journal of Digital Forensics, Security and Law

The growth in the computer forensic field has created a demand for new software (or increased functionality to existing software) and a means to verify that this software is truly forensic i.e. capable of meeting the requirements of the trier of fact. In this work, we review our previous work---a function oriented testing framework for validation and verification of computer forensic tools. This framework consists of three parts: function mapping, requirements specification and reference set development. Through function mapping, we give a scientific and systemized description of the fundamentals of computer forensic discipline, i.e. what functions are needed in the …

Clustering Spam Domains And Destination Websites: Digital Forensics With Data Mining, Chun Wei, Alan Sprague, Gary Warner, Anthony Skjellum

Journal of Digital Forensics, Security and Law

Spam related cyber crimes have become a serious threat to society. Current spam research mainly aims to detect spam more effectively. We believe the identification and disruption of the supporting infrastructure used by spammers is a more effective way of stopping spam than filtering. The termination of spam hosts will greatly reduce the profit a spammer can generate and thwart his ability to send more spam. This research proposes an algorithm for clustering spam domains extracted from spam emails based on the hosting IP addresses and tracing the IP addresses over a period of time. The results show that many …

Developing Voip Honeypots: A Preliminary Investigation Into Malfeasant Activity, Craig Valli

Journal of Digital Forensics, Security and Law

30 years ago PABX systems were compromised by hackers wanting to make long distance calls at some other entities expense. This activity faded as telephony became cheaper and PABX systems had countermeasures installed to overcome attacks. Now the world has moved onto the provision of telephony via broadband enabled Voice over Internet Protocol (VoIP) with this service now being provided as a replacement for conventional fixed wire telephony by major telecommunication providers worldwide. Due to increasing bandwidth it is possible for systems to support multiple voice connections simultaneously. The networked nature of the Internet allows for attackers of these VoIP …

Adaptation Of Pyflag To Efficient Analysis Of Seized Computer Data Storage, Aleksander Byrski, Wojciech Stryjewski, Bartłomiej Czechowicz

Journal of Digital Forensics, Security and Law

Based on existing software aimed at investigation support in the analysis of computer data storage seized during investigation (PyFlag), an extension is proposed involving the introduction of dedicated components for data identification and filtering. Hash codes for popular software contained in NIST/NSRL database are considered in order to avoid unwanted files while searching and to classify them into several categories. The extension allows for further analysis, e.g. using artificial intelligence methods. The considerations are illustrated by the overview of the system's design.

Avoiding Sanctions At The E-Discovery Meet-And-Confer In Common Law Countries, Milton Luoma, Vicki Luoma

Journal of Digital Forensics, Security and Law

The rules of civil procedure in common law countries have been amended to better deal with the requirements of electronic discovery. One of the key changes in case management is the scheduling of a meet-and-confer session where the parties to litigation must meet early in the case before any discovery procedures have begun to exchange information regarding the nature, location, formats, and pertinent facts regarding custody and control of a party’s electronically stored information (ESI). Failure to abide by the rules and participate in good faith at the meet-and-confer session can have dire consequences for the parties and lawyers involved. …

Malware Forensics: Discovery Of The Intent Of Deception, Murray Brand, Craig Valli, Andrew Woodward

Journal of Digital Forensics, Security and Law

Malicious software (malware) has a wide variety of analysis avoidance techniques that it can employ to hinder forensic analysis. Although legitimate software can incorporate the same analysis avoidance techniques to provide a measure of protection against reverse engineering and to protect intellectual property, malware invariably makes much greater use of such techniques to make detailed analysis labour intensive and very time consuming. Analysis avoidance techniques are so heavily used by malware that the detection of the use of analysis avoidance techniques could be a very good indicator of the presence of malicious intent. However, there is a tendency for analysis …

Digital Records Forensics: A New Science And Academic Program For Forensic Readiness, Luciana Duranti, Barbara Endicott-Popovsky

Journal of Digital Forensics, Security and Law

This paper introduces the Digital Records Forensics project, a research endeavour located at the University of British Columbia in Canada and aimed at the development of a new science resulting from the integration of digital forensics with diplomatics, archival science, information science and the law of evidence, and of an interdisciplinary graduate degree program, called Digital Records Forensics Studies, directed to professionals working for law enforcement agencies, legal firms, courts, and all kind of institutions and business that require their services. The program anticipates the need for organizations to become “forensically ready,” defined by John Tan as “maximizing the ability …

Solid State Drives: The Beginning Of The End For Current Practice In Digital Forensic Recovery?, Graeme B. Bell, Richard Boddington

Journal of Digital Forensics, Security and Law

Digital evidence is increasingly relied upon in computer forensic examinations and legal proceedings in the modern courtroom. The primary storage technology used for digital information has remained constant over the last two decades, in the form of the magnetic disc. Consequently, investigative, forensic, and judicial procedures are well-established for magnetic disc storage devices (Carrier, 2005). However, a paradigm shift has taken place in technology storage and complex, transistor-based devices for primary storage are now increasingly common. Most people are aware of the transition from portable magnetic floppy discs to portable USB transistor flash devices, yet the transition from magnetic hard …

Book Review: Digital Forensic Evidence Examination (2nd Ed.), Gary C. Kessler

Journal of Digital Forensics, Security and Law

On the day that I sat down to start to write this review, the following e-mail came across on one of my lists: Person A and Person B write back and forth and create an email thread. Person A then forwards the email to Person C, but changes some wording in the email exchange between A & B. What is the easiest way (and is it even possible) to find out when that earlier email message was altered before sent to Person C? Before you try to answer these questions, read Fred Cohen's Digital Forensic Evidence Examination. His book won't …

Identifying A Computer Forensics Expert: A Study To Measure The Characteristics Of Forensic Computer Examiners, Gregory H. Carlton, Reginald Worthley

Journal of Digital Forensics, Security and Law

The usage of digital evidence from electronic devices has been rapidly expanding within litigation, and along with this increased usage, the reliance upon forensic computer examiners to acquire, analyze, and report upon this evidence is also rapidly growing. This growing demand for forensic computer examiners raises questions concerning the selection of individuals qualified to perform this work. While courts have mechanisms for qualifying witnesses that provide testimony based on scientific data, such as digital data, the qualifying criteria covers a wide variety of characteristics including, education, experience, training, professional certifications, or other special skills. In this study, we compare task …

Concerning File Slack, Stephen P. Larson

Annual ADFSL Conference on Digital Forensics, Security and Law

In this paper we discuss the phenomena known as file slack. File slack is created each time a file is created on a hard disk, and can contain private or confidential data. Unfortunately, the methods used by Microsoft Windows operating systems to organize and save files require file slack, and users have no control over what data is saved in file slack. This document will help create awareness about the security issue of file slack and discuss research results concerning file slack.

Don’T Touch That! And Other E-Discovery Issues, Linda Volonino

Annual ADFSL Conference on Digital Forensics, Security and Law

The ability to preserve and access electronically stored information (ESI) took on greater urgency when amendments to the Federal Rules of Civil Procedure went into effect in December 2006. These amendments, referred to as the electronic discovery (e-discovery) amendments, focus on the discovery phase of civil litigation, audits, or investigations. Discovery is the investigative phase of a legal case when opponents learn what evidence is available and how accessible it is. When ESI is the subject of discovery, it is called e-discovery. Recognizing that most business and personal records and communications are electronic, Judge Shira A. Scheindlin stated, "We used …
