Sql Injection: The Longest Running Sequel In Programming History, Matthew Horner, Thomas Hyslip

Journal of Digital Forensics, Security and Law

One of the risks to a company operating a public-facing website with a Structure Query Language (SQL) database is an attacker exploiting the SQL injection vulnerability. An attacker can cause an SQL database to perform actions that the developer did not intend like revealing, modifying, or deleting sensitive data. This can cause a loss of confidentiality, integrity, and availability of information in a company’s database, and it can lead to severe costs of up to $196,000 per successful injection attack (NTT Group, 2014). This paper discusses the history of the SQL injection vulnerability, focusing on:

• How an attacker can exploit …

A Power Grid Incident Identification Based On Physically Derived Cyber-Event Detection, Travis Atkison, Nathan Wallace

Journal of Digital Forensics, Security and Law

This article proposes a cyber-event detection framework to aid in incident Identification and digital forensics cases aimed at investigating cyber crime committed against the critical infrastructure power grid. However, unlike other similar investigative techniques, the proposed approach examines only the physical information to derive a cyber conclusion. The developed framework extracts information from the physical parameters stored in historical databases of SCADA systems. The framework uses a pseudo-trusted model derived from randomly selected power system observations found in the historical databases. Afterwards, a technique known as Bayesian Model Averaging is used to average the models and create a more trusted …

Towards A More Representative Definition Of Cyber Security, Daniel Schatz, Rabih Bashroush, Julie Wall

Journal of Digital Forensics, Security and Law

In recent years, ‘Cyber Security’ has emerged as a widely-used term with increased adoption by practitioners and politicians alike. However, as with many fashionable jargon, there seems to be very little understanding of what the term really entails. Although this is may not be an issue when the term is used in an informal context, it can potentially cause considerable problems in context of organizational strategy, business objectives, or international agreements. In this work, we study the existing literature to identify the main definitions provided for the term ‘Cyber Security’ by authoritative sources. We then conduct various lexical and semantic …

Forensic Cell Site Analysis: A Validation & Error Mitigation Methodology, John B. Minor

Journal of Digital Forensics, Security and Law

The E911 Initiative in the mid-1990s established an opportunity to obtain location specific digital evidence of subscriber activity from cellular carriers. Call Detail Records (CDR) containing Cell Site Location Information (CSLI) evidence production was made available from cellular carriers in response to the CALEA, 911 and ECPA acts. In the late 1990s, cellular carriers began to produce evidence for investigative and litigation purposes. CDR/CSLI evidence has become an important evidentiary focus in the courtroom. This research project resulted in the creation of a method of validating cellular carrier records accuracy and mitigating errors in forensic cell site analyst conclusions. The …

Since the recent release of Viber 6.0 in March/April 2016 and its further updates, Viber provides end-to-end encryption based on Open Whisper Signal security architecture. With proprietary communication protocol scattered on distributed cluster of servers in different countries and secure cryptographic primitives, Viber offers a difficult paradigm of traffic analysis. In this paper, we present a novel methodology of identification of Viber traffic over the network and established a model which can classify its services of audio and audio/video calls, message …

Applying A Contingency Framework To Digital Forensic Processes In Cloud Based Acquisitions, Diane Barrett

Journal of Digital Forensics, Security and Law

The change in business models to incorporate a wide variety of cloud computing environments has resulted in the escalation of computer crimes in the areas of security breaches and hacking. Methods to acquire evidence in a cloud computing environment are limited due to the complexity of the cloud environment. Since digital acquisition processes in cloud computing environments are still in the infancy stages, there have been no studies in the application of existing frameworks to this type environment based on traditional forensic processes.

This paper describes a qualitative study conducted to develop a robust contingency framework for deciding when to …

Protecting Digital Evidence Integrity And Preserving Chain Of Custody, Makhdoom Syed Muhammad Baqir Shah, Shahzad Saleem, Roha Zulqarnain

Journal of Digital Forensics, Security and Law

Evidence is the key to solve any crime. Evidence integrity needs to be protected in order to make it admissible in the court of law. Digital evidence is more revealing, but it is fragile; it can easily be tampered with or modified. There are different techniques available to protect the integrity of digital evidence. Different automated digital evidence acquisition tools are available in the market. In this paper, we have analyzed two automated tools (EnCase and FTK Imager) that are used for disk imaging. These tools claim to protect the integrity of digital evidence. The techniques used by these tools …

Employer Liability And Bring Your Own Device: Do Existing Regulations Support Employer Liability For A Compromised Personal Device?, Beth A. Hutchens

Technology Law and Public Policy Clinic

As employers increasingly permit employees to use their personal devices (known as Bring Your Own Device, or “BYOD”) for business purposes, and as the risk of data exposure continues to rise, the question of how, when, and against whom to attach liability remains in flux. This paper will endeavor to explore employer liability as viewed through the lens of hacked or compromised BYOD devices. The research begins by identifying BYOD as a concept along with the risks and benefits incident to the practice. It then discusses current state and federal data protection regulations. It then explores recurring themes in data …

Sony, Cyber Security, And Free Speech: Preserving The First Amendment In The Modern World, Conrad Wilton

Pace Intellectual Property, Sports & Entertainment Law Forum

Reprinted from 16 U.C. Davis Bus. L.J. 309 (2016). This paper explores the Sony hack in 2014 allegedly launched by the North Korean government in retaliation over Sony’s production of The Interview and considers the hack’s chilling impact on speech in technology. One of the most devastating cyber attacks in history, the hack exposed approximately thirty- eight million files of sensitive data, including over 170,000 employee emails, thousands of employee social security numbers and unreleased footage of upcoming movies. The hack caused Sony to censor the film and prompted members of the entertainment industry at large to tailor their communication …

Interpretation Catalysts In Cyberspace, Rebecca Ingber

Faculty Scholarship

The cybersphere offers a rich space from which to explore the development of international law in a compressed time frame. This piece examines the soft law process over the last decade of the two Tallinn Manuals – handbooks on the international law of cyber warfare and cyber operations – as a valuable lens through which to witness the effects of “interpretation catalysts” on the evolution of international law. In prior work, I identified the concept of interpretation catalysts – discrete triggers for legal interpretation – and their influence on the path that legal evolution takes, including by compelling a decision-making …

Did Russian Cyber Interference In The 2016 Election Violate International Law?, Jens David Ohlin

Cornell Law Faculty Publications

When it was revealed that the Russian government interfered in the 2016 U.S. presidential election by hacking into the email system of the Democratic National Committee and releasing its emails, international lawyers were divided over whether the cyber-attack violated international law. President Obama seemingly went out of his way to describe the attack as a mere violation of “established international norms of behavior,” though some international lawyers were more willing to describe the cyber-attack as a violation of international law. However, identifying the exact legal norm that was contravened turns out to be harder than it might otherwise appear. To …

Algorithmic Discrimination White Paper, Vicky Wei, Teresa Stephenson

Technology Law and Public Policy Clinic

Technological innovation has led to the prevalent use of algorithms in everyday decision making. So ubiquitous is the application of algorithms that many may not recognize its impact on their daily lives. From online shopping to applying for a home loan, algorithms are at play in categorizing and filtering individuals to serve the goal of providing more accurate and efficient results than human decisionmaking would. At the basic level, algorithms are nothing more than a series of step-by-step instructions compiled by a computer, which then analyzes swaths of data based on those instructions. However, when algorithms use incorrect variables to …

Exploring Digital Evidence With Graph Theory, Imani Palmer, Boris Gelfand, Roy Campbell

Annual ADFSL Conference on Digital Forensics, Security and Law

The analysis phase of the digital forensic process is the most complex. The analysis phase remains very subjective to the views of the forensic practitioner. There are many tools dedicated to assisting the investigator during the analysis process. However, they do not address the challenges. Digital forensics is in need of a consistent approach to procure the most judicious conclusions from the digital evidence. The objective of this paper is to discuss the ability of graph theory, a study of related mathematical structures, to aid in the analysis phase of the digital forensic process. We develop a graph-based representation of …

Case Study: A New Method For Investigating Crimes Against Children, Hallstein Asheim Hansen, Stig Andersen, Stefan Axelsson, Svein Hopland

Annual ADFSL Conference on Digital Forensics, Security and Law

Investigations of crimes against children are often complex, both in terms of the varied and large amount of digital technology encountered and the offensive nature of the crimes. Such cases are numerous, large, and prioritised, requiring digital forensics competence. Earlier digital forensics was considered and treated as a typical forensic science like fingerprint analysis, performed in a laboratory isolated from the investigative team. This decoupled way of working has proved to be both inefficient and error prone.

At the Digital Forensic Unit of Oslo Police District we have developed a new way of working that addresses many of the problems …

Downstream Competence Challenges And Legal/Ethical Risks In Digital Forensics, Michael M. Losavio, Antonio Losavio

Annual ADFSL Conference on Digital Forensics, Security and Law

Forensic practice is an inherently human-mediated system, from processing and collection of evidence to presentation and judgment. This requires attention to human factors and risks which can lead to incorrect judgments and unjust punishments.

For digital forensics, such challenges are magnified by the relative newness of the discipline and the use of electronic evidence in forensic proceedings. Traditional legal protections, rules of procedure and ethics rules mitigate these challenges. Application of those traditions better ensures forensic findings are reliable. This has significant consequences where findings may impact a person's liberty or property, a person's life or even the political direction …

Understanding Deleted File Decay On Removable Media Using Differential Analysis, James H. Jones Jr, Anurag Srivastava, Josh Mosier, Connor Anderson, Seth Buenafe

Annual ADFSL Conference on Digital Forensics, Security and Law

Digital content created by picture recording devices is often stored internally on the source device, on either embedded or removable media. Such storage media is typically limited in capacity and meant primarily for interim storage of the most recent image files, and these devices are frequently configured to delete older files as necessary to make room for new files. When investigations involve such devices and media, it is sometimes these older deleted files that would be of interest. It is an established fact that deleted file content may persist in part or in its entirety after deletion, and identifying the …

Development Of A Professional Code Of Ethics In Digital Forensics, Kathryn C. Seigfried-Spellar, Marcus Rogers, Danielle M. Crimmins 2184089

Annual ADFSL Conference on Digital Forensics, Security and Law

Academics, government officials, and practitioners suggest the field of digital forensics is in need of a professional code of ethics. In response to this need, the authors developed and proposed a professional code of ethics in digital forensics. The current paper will discuss the process of developing the professional code of ethics, which included four sets of revisions based on feedback and suggestions provided by members of the digital forensic community. The final version of the Professional Code of Ethics in Digital Forensics includes eight statements, and we hope this is a step toward unifying the field of digital forensics …

Defining A Cyber Jurisprudence, Peter R. Stephenson Phd

Annual ADFSL Conference on Digital Forensics, Security and Law

Jurisprudence is the science and philosophy or theory of the law. Cyber law is a very new concept and has had, compared with other, older, branches of the law, little structured study. However, we have entered the cyber age and the law - on all fronts - is struggling to keep pace with technological advances in cyberspace. This research explores a possible theory and philosophy of cyber law, and, indeed, whether it is feasible to develop and interpret a body of law that addresses current and emerging challenges in cyber space.

While there is an expanding discussion of the nature …

Harnessing Predictive Models For Assisting Network Forensic Investigations Of Dns Tunnels, Irvin Homem, Panagiotis Papapetrou

Annual ADFSL Conference on Digital Forensics, Security and Law

In recent times, DNS tunneling techniques have been used for malicious purposes, however network security mechanisms struggle to detect them. Network forensic analysis has been proven effective, but is slow and effort intensive as Network Forensics Analysis Tools struggle to deal with undocumented or new network tunneling techniques. In this paper, we present a machine learning approach, based on feature subsets of network traffic evidence, to aid forensic analysis through automating the inference of protocols carried within DNS tunneling techniques. We explore four network protocols, namely, HTTP, HTTPS, FTP, and POP3. Three features are extracted from the DNS tunneled traffic: …

Towards An Effective Regime Against Online Copyright Infringement In India, Ashwin Ramakrishnan

LLM Theses

With Internet usage on the rise, it is important for India to establish an effective regulatory regime to combat piracy and mass copyright infringement online. This thesis argues that, in the face of unique legal and cultural challenges specific to India, present laws in the country have failed to do so. Unless and until these challenges are met it will be difficult to have an effective mechanism that deals with online copyright infringement. Countries like the United States, Canada, Ireland, and France have all adopted different regulatory models. However, this thesis argues that each not only have significant limitations on …
