Measuring Hacking Ability Using A Conceptual Expertise Task, Justin S. Giboney, Jeffrey G. Proudfoot, Sanjay Goel, Joseph S. Valacich

Annual ADFSL Conference on Digital Forensics, Security and Law

Hackers pose a continuous and unrelenting threat to organizations. Industry and academic researchers alike can benefit from a greater understanding of how hackers engage in criminal behavior. A limiting factor of hacker research is the inability to verify that self-proclaimed hackers participating in research actually possess their purported knowledge and skills. This paper presents current work in developing and validating a conceptual-expertise based tool that can be used to discriminate between novice and expert hackers. The implications of this work are promising since behavioral information systems researchers operating in the information security space will directly benefit from the validation of …

Inivited Paper - Potential Changes To Ediscovery Rules In Federal Court: A Discussion Of The Process, Substantive Changes And Their Applicability And Impact On Virginia Practice, Joseph J. Schwerha, Susan L. Mitchell, John W. Bagby

Annual ADFSL Conference on Digital Forensics, Security and Law

The Federal Rules of Civil Procedure (FRCP) are subject to a unique process also once used in revising the Federal Rules of Evidence (FRE). Today, this process is followed in revisions of the FRCP, the Federal Rules of Criminal Procedure and the Federal Bankruptcy Rules. This unique rulemaking process differs significantly from traditional notice and comment rulemaking required for a majority of federal regulatory agencies under the Administrative Procedure Act (APA).1 Most notably, rule-making for the federal courts’ procedural matters remain unaffected by the invalidation of legislative veto. It is still widely, but wrongly believed, that the legislative veto was …

On The Network Performance Of Digital Evidence Acquisition Of Small Scale Devices Over Public Networks, Irvin Homem, Spyridon Dosis

Annual ADFSL Conference on Digital Forensics, Security and Law

While cybercrime proliferates – becoming more complex and surreptitious on the Internet – the tools and techniques used in performing digital investigations are still largely lagging behind, effectively slowing down law enforcement agencies at large. Real-time remote acquisition of digital evidence over the Internet is still an elusive ideal in the combat against cybercrime. In this paper we briefly describe the architecture of a comprehensive proactive digital investigation system that is termed as the Live Evidence Information Aggregator (LEIA). This system aims at collecting digital evidence from potentially any device in real time over the Internet. Particular focus is made …

Starting with Windows 7, Microsoft introduced a new feature to the Windows Operating Systems called Jump Lists. Jump Lists stores information about user activities on the host machine. These activities may include links to the recently visited web pages, applications executed, or files processed. Computer forensics investigators may find traces of misuse in Jump Lists auto saved files. In this research, we investigate the forensics values of Jump Lists data. Specifically, we use several tools to view Jump Lists data on a virtual machine. We show that each tool reveal certain types of information about user’s activity on the host …

An Empirical Comparison Of Widely Adopted Hash Functions In Digital Forensics: Does The Programming Language And Operating System Make A Difference?, Satyendra Gurjar, Ibrahim Baggili, Frank Breitinger, Alice Fischer

Annual ADFSL Conference on Digital Forensics, Security and Law

Hash functions are widespread in computer sciences and have a wide range of applications such as ensuring integrity in cryptographic protocols, structuring database entries (hash tables) or identifying known files in forensic investigations. Besides their cryptographic requirements, a fundamental property of hash functions is efficient and easy computation which is especially important in digital forensics due to the large amount of data that needs to be processed when working on cases. In this paper, we correlate the runtime efficiency of common hashing algorithms (MD5, SHA-family) and their implementation. Our empirical comparison focuses on C-OpenSSL, Python, Ruby, Java on Windows and …

Two Challenges Of Stealthy Hypervisors Detection: Time Cheating And Data Fluctuations, Igor Korkin

Annual ADFSL Conference on Digital Forensics, Security and Law

Hardware virtualization technologies play a significant role in cyber security. On the one hand these technologies enhance security levels, by designing a trusted operating system. On the other hand these technologies can be taken up into modern malware which is rather hard to detect. None of the existing methods is able to efficiently detect a hypervisor in the face of countermeasures such as time cheating, temporary self-uninstalling, memory hiding etc. New hypervisor detection methods which will be described in this paper can detect a hypervisor under these countermeasures and even count several nested ones. These novel approaches rely on the …

The Use Of Criminal Profilers In The Prosecution Of Serial Killers, Chelsea Van Aken

Themis: Research Journal of Justice Studies and Forensic Science

The purpose of this paper is to analyze the concept of criminal profiling in terms of serial killers in the United States. The research provided in this paper was found using the most recent research available on the topic. The FBI’s Behavioral Unit, or National Center for the Analysis of Violent Crime (NCAVC), is the current leading law enforcement agency that investigates these types of crimes. They utilize definitions, typographies, and motives to create a criminal profile to investigate serial killings. Ultimately, these profiles are inadequate because they are inconclusive and exclude multiple suspects that are potentially dangerous. Therefore, criminal …

The "Csi Effect" And Its Potential Impact On Juror Decisions, John Alldredge

Themis: Research Journal of Justice Studies and Forensic Science

The “CSI Effect” was first described in the media as a phenomenon resulting from viewing forensic and crime based television shows. This effect influences jurors to have unrealistic expectations of forensic science during a criminal trial and affect jurors’ decisions in the conviction or acquittal process. Research has shown the “CSI Effect” has a possible pro-defense bias, in that jurors are less likely to convict without the presence of some sort of forensic evidence. Some studies show actors in the criminal justice system are changing their tactics, as if this effect has a significant influence, causing them to request unnecessary …

Reducing Contamination In Forensic Science, Carly Balk

Themis: Research Journal of Justice Studies and Forensic Science

The sensitivity of modern forensic techniques has drastically increased, with sensitive technology detecting even the smallest traces of DNA evidence left behind. This has made it possible to detect DNA profiles deposited through contamination. When DNA contamination occurs in forensic science, it has the potential to change the outcome of a criminal investigation and may have significant social and financial repercussions. A compilation of global research shows that DNA evidence transfer can occur during forensic product manufacturing, the fingerprinting process, or even autopsy and crime lab examinations. These vital areas of the forensic investigation are vulnerable to contamination, and national …

Mathematics In Forensic Firearm Examination, Erin N. Zalewski

Renée Crown University Honors Thesis Projects - All

Forensic Science encompasses many disciplines that employ the scientific method to examine, analyze, and interpret physical evidence in the courtroom. The discipline of Forensic Firearm Examination involves the examination and comparison of ballistic evidence components to determine if they came from the same source. In other words, firearm examiners are tasked with determining whether spent cartridge cases or bullets were fired through the same gun. Examination of ballistic evidence can involve the employment of automated matching systems, comparison microscopy, and mathematical analysis. The comparison microscope is the tool of the firearm examiner and allows for the simultaneous view of ballistic …

Brief For Professor Albert E. Scherr As Amicus Curiae In Support Of Petitioner, Albert E. Scherr

Law Faculty Scholarship

INTRODUCTION AND SUMMARY OF ARGUMENT Professor Scherr agrees with petitioner that review is warranted because the Maryland Court of Appeals decision is erroneous. The Fourth Amendment does not sanction police harvesting of DNA without probable cause and a warrant and without the subject’s knowledge or consent, to be used however the authorities deem appropriate and without restriction. The Maryland Court of Appeals’ decision is contrary to the Supreme Court’s jurisprudence as articulated in the Riley v. California – Maryland v. King – United States v. Jones trilogy. This case fits squarely in the center of the triangle formed by that …

Quantitative Assessment Of The Effects Of Microbial Degradation Of A Simple Hydrocarbon Mixture, Jessica Kindell

Electronic Theses and Dissertations

Ignitable liquids consist of either a single organic compound or a complex organic mixture. In regards to fire debris analysis, the analyst is responsible for determining if an ignitable liquid residue is present. However, when extracted from soil-containing fire debris evidence, chemical degradation from microorganisms is observed to result in the loss of compounds based on chemical structure. It can also happen when the evidence container is stored at room temperature before analysis. This can present a challenge to the fire debris analyst when identifying and classifying the ignitable liquid residue based on the criteria established by standard test methods. …
