This book is titled Cyber Crime and Digital Evidence for one fundamental reason: it is more likely that a lawyer or judge will encounter digital evidence in almost every case, given its ubiquity in modern life. Nearly half of this book is devoted to the government's acquisition of digital evidence, regardless of the underlying crime. The balance of the book is devoted to various aspects of the criminal law that have been modified to address new forms of bad behavior that are facilitated by digital devices and networks.
Cyber Crime and Digital Evidence: Materials and Cases is designed to be an accessible introduction to Cyber Crime and Digital Evidence. The title illuminates two significant aspects of this book. First, cyber crime is only a subset of a much broader trend in the criminal area, which is the use of digital evidence in virtually all criminal cases. Hence, it is important to understand the legal framework that regulates obtaining that increasingly used and important evidence. Second, this book provides a broader framework than an endless stream of cases offers. Law students deserve the broader context and, hopefully, will get some of it with this book. The second edition includes new cases, particularly United States Supreme Court cases on searching cell phones, have begun to add clarity and needed guidance to the acquisition of digital evidence procedures required of law enforcement. New technology and case law discussing the impact of that technology have been added throughout the book.
This paper presents a proof of concept (PoC) framework for social media user attribution. The framework aims to provide digital evidence that can be used to substantiate user activity in live triage investigations. This paper highlights the use of live triage as a viable technique for the investigation of social media activity, contextualizing user activity and attributing actions to users. It discusses the reliability of artefacts other than the communications content as a means of drawing inferences about user social media activity, taking into account the proportionality and relevance of such evidence.

This book offers a comprehensive and integrative introduction to cybercrime. It provides an authoritative synthesis of the disparate literature on the various types of cybercrime, the global investigation and detection of cybercrime and the role of digital information, and the wider role of technology as a facilitator for social relationships between deviants and criminals. It includes coverage of:
This book includes lively and engaging features, such as discussion questions, boxed examples of unique events and key figures in offending, quotes from interviews with active offenders, and a full glossary of terms. It is supplemented by a companion website that includes further exercises for students and instructor resources. This text is essential reading for courses on cybercrime, cyber-deviancy, digital forensics, cybercrime investigation, and the sociology of technology.

Students gain hands-on experience using real state-of-the-art computer forensic tools employed by law enforcement.
Pioneers in the industry, providing quality services since 1984, Burgess has extracted digital data from tens of thousands of clients' computers and media, whether owned or seized by court order, through four decades.
Computer forensics is the application of investigation and analysis techniques to gather and preserve evidence from a particular computing device in a way that is suitable for presentation in a court of law. The goal of computer forensics is to perform a structured investigation and maintain a documented chain of evidence to find out exactly what happened on a computing device and who was responsible for it.
Computer forensics -- which is sometimes referred to as computer forensic science -- essentially is data recovery with legal compliance guidelines to make the information admissible in legal proceedings. The terms digital forensics and cyber forensics are often used as synonyms for computer forensics.
In the civil and criminal justice system, computer forensics helps ensure the integrity of digital evidence presented in court cases. As computers and other data-collecting devices are used more frequently in every aspect of life, digital evidence -- and the forensic process used to collect, preserve and investigate it -- has become more important in solving crimes and other legal issues.
The average person never sees much of the information modern devices collect. For instance, the computers in cars continually collect information on when a driver brakes, shifts and changes speed without the driver being aware. However, this information can prove critical in solving a legal matter or a crime, and computer forensics often plays a role in identifying and preserving that information.
Digital evidence isn't just useful in solving digital-world crimes, such as data theft, network breaches and illicit online transactions. It's also used to solve physical-world crimes, such as burglary, assault, hit-and-run accidents and murder.
Businesses also use computer forensics to track information related to a system or network compromise, which can be used to identify and prosecute cyber attackers. Businesses can also use digital forensic experts and processes to help them with data recovery in the event of a system or network failure caused by a natural or other disaster.
As the world becomes more reliant on digital technology for the core functions of life, cybercrime is rising. As such, computer forensic specialists no longer have a monopoly on the field. See how the police in the U.K. are adopting computer forensic techniques to keep up with increasing rates of cybercrime.
Often, multiple tools are used in computer forensic investigations to validate the results they produce. Learn how a researcher at Kaspersky Lab in Asia created an open source forensics tool for remotely collecting malware evidence without compromising system integrity.
Investigators use a variety of techniques and proprietary forensic applications to examine the copy they've made of a compromised device. They search hidden folders and unallocated disk space for copies of deleted, encrypted or damaged files. Any evidence found on the digital copy is carefully documented in a finding report and verified with the original device in preparation for legal proceedings that involve discovery, depositions or actual litigation.
Find out more about computer forensic analytics in this chapter from the book Python Forensics: A Workbench for Inventing and Sharing Digital Forensic Technology, by Chet Hosmer. It shows how to use Python and cybersecurity technology to preserve digital evidence.
Certified Digital Media Examiners are investigators who have the education, training and experience to properly exploit this sensitive evidence. That said, there is no single certifying body, and certification programs can contain different courses of study. Generally speaking, these professionals have demonstrated core competencies in pre-examination procedures and legal issues, media assessment and analysis, data recovery, specific analysis of recovered data, documentation and reporting, and presentation of findings. While certification of examiners is not required in most agencies, it is becoming a widely valued asset and the numbers of certified examiners will increase. Vendor-neutral (not software based, but theory- and process-based) certification is offered through the Digital Forensics Certification Board (DFCB), an independent certifying organization for digital evidence examiners, the National Computer Forensics Academy at the High Tech Crime Institute and some colleges. 59ce067264
