The Amorphous Nature Of Hackers: An Exploratory Study, Kento Yasuhara, Daniel Walnycky, Ibrahim Baggili, Ahmed Alhishwan
Annual ADFSL Conference on Digital Forensics, Security and Law
In this work, we aim to better understand outsider perspectives of the hacker community through a series of situation based survey questions. By doing this, we hope to gain insight into the overall reputation of hackers from participants in a wide range of technical and non-technical backgrounds. This is important to digital forensics since convicted hackers will be tried by people, each with their own perception of who hackers are. Do cyber crimes and national security issues negatively affect people’s perceptions of hackers? Does hacktivism and information warfare positively affect people’s perception of hackers? Do individual personality factors affect one’s …

Smart Home Forensics: Identifying Ddos Attack Patterns On Iot Devices, Samuel Ho, Hope Greeson, Umit Karabiyik
Annual ADFSL Conference on Digital Forensics, Security and Law
Smart homes are becoming more common as more people integrate IoT devices into their home environment. As such, these devices have access to personal data on their homeowners’ networks. One of the advantages of IoT devices is that they are compact. However, this limits the incorporation of security measures in their hardware. Misconfigured IoT devices are commonly the target of malicious attacks. Additionally, distributed denial-of-service attacks are becoming more common due to applications and software that provides users with easy-to-use user interfaces. Since one vulnerable device is all an attacker needs to launch an attack on a network, in regards …

Detection Of Overlapping Passive Manipulation Techniques In Image Forensics, Gianna S. Lint, Umit Karabiyik
Annual ADFSL Conference on Digital Forensics, Security and Law
With a growing number of images uploaded daily to social media sites, it is essential to understand if an image can be used to trace its origin. Forensic investigations are focusing on analyzing images that are uploaded to social media sites resulting in an emphasis on building and validating tools. There has been a strong focus on understanding active manipulation or tampering techniques and building tools for analysis. However, research on manipulation is often studied in a vacuum, involving only one technique at a time. Additionally, less focus has been placed on passive manipulation, which can occur by simply uploading …
Evaluating A Test For Shedding Propensity Using Tape Lifts From Different Skin Locations, Xiao M. Chen
Evaluating A Test For Shedding Propensity Using Tape Lifts From Different Skin Locations, Xiao M. Chen
Student Theses
The shedding propensity of a person can assist data interpretation in casework when assessing the possibility of passive transfer for DNA analysis. Past studies on shedding propensity evaluated palmar skin (washed and unwashed) deposits. This study compared different skin locations with respect to shedding propensity, and explored the potential of tape-lifts as a skin surface collection method. Eight different skin types and samples were collected with adhesive tape disks from 28 participants over three non-consecutive days; the washed and unwashed fingers from both hands, toe, and arm, neck below ear, and nape. Samples were extracted, quantified, amplified, genotyped, and evaluated …
Increasing Accountability For Rape In Liberia: The Need For A Forensic System To Increase The Success Rates Of Prosecution, Pela Boker Wilson
Increasing Accountability For Rape In Liberia: The Need For A Forensic System To Increase The Success Rates Of Prosecution, Pela Boker Wilson
William & Mary Journal of Race, Gender, and Social Justice
The need for a fully functioning forensic system has been identified by the Liberian government and international partners, but it has not been addressed. This Article argues that despite a robust framework put in place to create accountability for rape, Liberia needs a system of collecting and processing forensic evidence to increase the success rate of prosecutions that currently fail due to the inadequacy of non-forensic evidence.
The Absence Or Misuse Of Statistics In Forensic Science As A Contributor To Wrongful Convictions: From Pattern Matching To Medical Opinions About Child Abuse, Keith A. Findley
The Absence Or Misuse Of Statistics In Forensic Science As A Contributor To Wrongful Convictions: From Pattern Matching To Medical Opinions About Child Abuse, Keith A. Findley
Dickinson Law Review (2017-Present)
The new scrutiny that has been applied to the forensic sciences since the emergence of DNA profiling as the gold standard three decades ago has identified numerous concerns about the absence of a solid scientific footing for most disciplines. This article examines one of the lesser-considered problems that afflicts virtually all of the pattern-matching (or “individualization”) disciplines (largely apart from DNA), and even undermines the validity of other forensic disciplines like forensic pathology and medical determinations about child abuse, particularly Shaken Baby Syndrome/Abusive Head Trauma (SBS/AHT). That problem is the absence or misuse of statistics. This article begins by applying …

Towards Increasing Trust In Expert Evidence Derived From Malware Forensic Tools, Ian M. Kennedy, Blaine Price, Arosha Bandara
Journal of Digital Forensics, Security and Law
Following a series of high profile miscarriages of justice in the UK linked to questionable expert evidence, the post of the Forensic Science Regulator was created in 2008. The main objective of this role is to improve the standard of practitioner competences and forensic procedures. One of the key strategies deployed to achieve this is the push to incorporate a greater level of scientific conduct in the various fields of forensic practice. Currently there is no statutory requirement for practitioners to become accredited to continue working with the Criminal Justice System of England and Wales. However, the Forensic Science Regulator …

Analyses Of Prosecutorial Power And Discretion In Mississippi: Evaluating Proposals To Address Misconduct And Abuse, Lucy Pruitt
Analyses Of Prosecutorial Power And Discretion In Mississippi: Evaluating Proposals To Address Misconduct And Abuse, Lucy Pruitt
Honors Theses
This thesis seeks to create a policy proposal in order to address incidences of prosecutorial misconduct and abuse of discretion in the Mississippi criminal justice system. To do so, the author has summarized and analyzed seven criminal cases in which defendants have become victims of prosecutorial misconduct in order to shed light on the lack of prosecutorial accountability in the state’s criminal justice system. In an attempt to solve the problem, the author has developed a novel grading rubric in order to objectively and systematically analyze and evaluate previously proposed policy recommendations by legal experts and justice organizations. The successes …
Digital Forensic Readiness: An Examination Of Law Enforcement Agencies In The State Of Maryland, James B. Mcnicholas Iii
Digital Forensic Readiness: An Examination Of Law Enforcement Agencies In The State Of Maryland, James B. Mcnicholas Iii
Masters Theses & Doctoral Dissertations
Digital forensic readiness within the law enforcement community, especially at the local level, has gone mostly unexplored. As a result, a current lack of data exists that examines the digital forensic readiness of individual agencies, the possibility of proximity relationships, and correlations between readiness and backlogs. This quantitative, crosssectional research study sought to explore these issues by focusing on the state of Maryland. The study resulted in the creation of a digital forensic readiness scoring model that was then used to assign digital forensic readiness scores to thirty (30) of the one-hundred-forty-one (141) law enforcement agencies throughout Maryland. It was …
The Costs And Benefits Of Forensics, Brandon L. Garrett
The Costs And Benefits Of Forensics, Brandon L. Garrett
Faculty Scholarship
Supreme Court Justice Louis Brandeis famously wrote that states can be laboratories for experimentation in law and policy. Disappointingly, however, the actual laboratories that states and local governments run are not a home for experimentation. We do not have adequate information about either the costs or the benefits of forensic testing or allocation of resources. Increased spending and expansion of crime laboratories has perversely accompanied growing backlogs. Poor quality control has resulted in a series of audits and even closures of crime laboratories. In response to these problems, however, some laboratories and some entire states have developed new approaches toward …

Catching Killers With Consumer Genetic Information, Angela Hackstadt
Catching Killers With Consumer Genetic Information, Angela Hackstadt
University Libraries Faculty Scholarship
In April 2018, Joseph James D'Angelo was arrested as a suspect in the Golden State Killer case. DNA evidence collected at a 1980 crime scene finally shed light on the murderer's identity in early 2018 when investigators turned to GEDMatch, a service that allows users to upload and share DNA data obtained from consumer genetic tests. Consumer genetic testing, DNA collection, and familial DNA searching all raise ethical and privacy concerns. If investigators are using genetic genealogy to solve cold cases, where does that leave consumers?

We also highlight what information the application accesses and what it …
Scientific Evidence Admissibility: Improving Judicial Proceedings To Decrease Erroneous Outcomes, Leica Kwong
Scientific Evidence Admissibility: Improving Judicial Proceedings To Decrease Erroneous Outcomes, Leica Kwong
Themis: Research Journal of Justice Studies and Forensic Science
In the United States, Federal Rules of Evidence 702, the Frye and Daubert standards govern the admissibility of scientific evidence in the courtroom. Some states adopted Frye while others adopted Daubert, causing varying judicial outcomes. The verdicts in some cases may be erroneous due to a nationally used standard. Frye has broad criteria of requiring scientific evidence to be generally accepted. While Daubert contains more requirements for the evidence to be admissible, such as peer review, publication, and scientific principles. Daubert, alongside FRE 702, provides a thorough guideline for trial judges who have the gatekeeping role to decide admissibility aiming …

Physical Match: Uniqueness Of Torn Paper, Marilyn Aguilar
Themis: Research Journal of Justice Studies and Forensic Science
In the forensic science field, it is generally accepted that all tears and fractures are unique; however, there is limited scientific evidence to support this. This study tests the claim that all tears are unique, focusing on paper. One-hundred Office Depot brand 3” x 5” blank, white index cards were torn in half by hand. Six halves were randomly removed; the remaining 94 halves were mixed and then matched by a novice using end-match analysis. The removal of the 6 random halves left 44 matching pairs. Of the remaining halves, all 44 pairs were correctly matched. The results show that …

Optimizing A Method For Dna Recovery While Preserving Latent Prints On Paper, Niti Dalal
Student Theses
Paper evidence is commonly encountered in cases of kidnapping, threatening letters, extortion, and bank robbery, and the optimal workflow between latent print processing and DNA collection is of interest to the forensic community. The overall aim of this project was to achieve optimal amounts of DNA for typing without destroying the fingerprint. The first study compared two collection techniques—tape-lifting by Scotch Removable Poster Tape and dry swabbing with FLOQSwabs— using prints deposited in defined locations. Samples were processed for DNA and developed with 1,2-indanedione. The second aim was to determine if visualizing print locations with fingerprint powder prior to DNA …
Revolution In Crime: How Cryptocurrencies Have Changed The Criminal Landscape, Igor Groysman
Revolution In Crime: How Cryptocurrencies Have Changed The Criminal Landscape, Igor Groysman
Student Theses
This thesis will examine the ways in which various cryptocurrencies have impacted certain traditional crimes. While crime is always evolving with technology, cryptocurrencies are a game changer in that they provide anonymous and decentralized payment systems which, while they can be tracked in a reactive sense via the blockchain, are seen by criminals as having better uses for them than traditional fiat currencies, such as the ability to send money relatively fast to another party without going through an intermediary, or the ability to obscure the origin of the money for money laundering purposes. Every week there are new cryptocurrencies …

Experts bedeviled the legal system long before seventeenth-century Salem, when the town's good citizens relied on youthful accusers and witchcraft experts to identify the devil's servants in their midst. As in Salem, claims of expertise have often been questioned and objections raised about the bases of expert knowledge. Expertise, then and now, did not have to be based on science; but the importance of science and the testimony of scientific experts has since medieval times been woven into the fabric of the English jurisprudence that Americans inherited. In cases as long ago as 1299 we find examples of courts seeking …

Lacking Regulated Policy For Dna Evidence, Maia Lister
Lacking Regulated Policy For Dna Evidence, Maia Lister
Themis: Research Journal of Justice Studies and Forensic Science
Despite its strong presence in criminal justice, DNA analysis is still a minimally regulated area. This minimal regulation devalues DNA evidence through the inconsistencies in these areas. The analysis methods of low template DNA lack a uniform method resulting in varying levels of reliability. Utilizing familial searches to assist in criminal investigations can potentially violate citizen rights. Such violations can also be found in the collection of DNA samples before an arrestee is tried or convicted. There are, however, regulations that could be applied universally to combat the problems that were discussed.

Positive Identification Of Lsb Image Steganography Using Cover Image Comparisons, Michael Pelosi, Nimesh Poudel, Pratap Lamichhane, Devon Lam, Gary Kessler, Joshua Macmonagle
Annual ADFSL Conference on Digital Forensics, Security and Law
In this paper we introduce a new software concept specifically designed to allow the digital forensics professional to clearly identify and attribute instances of LSB image steganography by using the original cover image in side-by-side comparison with a suspected steganographic payload image. The “CounterSteg” software allows detailed analysis and comparison of both the original cover image and any modified image, using sophisticated bit- and color-channel visual depiction graphics. In certain cases, the steganographic software used for message transmission can be identified by the forensic analysis of LSB and other changes in the payload image. The paper demonstrates usage and typical …
