Steganography is the art and science of concealing information in such a way that only the sender and intended recipient of a message should be aware of its presence. Digital steganography has been used in the past on a variety of media including executable files, audio, text, games and, notably, images. Additionally, there is increasing research interest towards the use of video as a media for steganography, due to its pervasive nature and diverse embedding capabilities. In this work, we examine the embedding algorithms and other security characteristics of several video steganography tools. We show how all feature basic and severe security weaknesses. This is potentially a very serious threat to the security, privacy and anonymity of their users. It is important to highlight that most steganography users have perfectly legal and ethical reasons to employ it. Some common scenarios would include citizens in oppressive regimes whose freedom of speech is compromised, people trying to avoid massive surveillance or censorship, political activists, whistle blowers, journalists, etc. As a result of our findings, we strongly recommend to cease any use of these tools, and to remove any contents that may have been hidden, and any carriers stored, exchanged and/or uploaded online. For many of these tools, carrier files will be trivial to detect, potentially compromising any hidden data and the parties involved in the communication. We finish this work by presenting our steganalytic results, that highlight a very poor current state of the art in practical video steganography tools. There is unfortunately a complete lack of secure and publicly available tools, and even commercial tools offer very poor security. We therefore encourage the steganography community to work towards the development of more secure and accessible video steganography tools, and make them available for the general public. The results presented in this work can also be seen as a useful resource for forensic examiners to determine the existence of any video steganography materials over the course of a computer forensic investigation.

E-mail has emerged as the most important application on the Internet for communication of messages, delivery of documents and carrying out transactions and is used not only from computers, but many other electronic gadgets such as mobile phones. This paper is an attempt to illustrate e-mail architecture from forensics perspective.  Also, this paper projects the need for e-mail forensic investigation and lists various methods and tools used for its realization. A detailed header analysis of a multiple tactic spoofed e-mail message is carried out in this paper. It also discusses various possibilities for detection of spoofed headers and identification of its originator. Furthermore, difficulties that may be faced by investigators during forensic investigation of an e-mail message have been discussed along with their possible solutions. Our focus is on email header analysis phase offered by the tools. We examine the capability of a particular tools such as EmailTrackerPro and  aid4mail in action. The paper describes the court case of cyber crime, the so-called identity theft in Internet communication via electronic mail by two business entities. Identity theft of e-mail addresses and false communications with a foreign company was carried out in order to indicate that a cash transaction of around EUR 100,000 was paid to the account of NN attackers and not to the account in the domestic Serbian bank.

This article outlines current issues of research on computer traces in the investigation of crimes at the stage of pre-trial investigation related to illegal trafficking of narcotic drugs, psychotropic substances or their analogues. The main ways of conducting drug trafficking in Ukraine using modern information technologies, that is, using computer technology (mostly mobile devices, personal portable computers) and software products (programs for communicating by means of calls and messages through the Internet, Web browsers, etc.) on the World Wide Web are analyzed. Based on the analysis of research and publications of scientists as well as on the basis of empirical research during computer forensic investigations connected with investigation of illegal distribution of narcotic drugs, methods of illicit goods distribution on the Internet along with methods for investigating computer technologies, which directly relate to drug trafficking using modern information technologies, has been considered. Types of data that can be extracted using specialized software in laboratories of computer research during computer forensic investigation, and which, in turn, can function as factual data and is the evidence of commission of crimes related to drug trafficking, psychotropic substances or their analogues are considered, namely, we are talking about such data as: information from messenger programs, web browsers, text messages, as well as from user files (including graphic, audio and video files); In addition, guiding questions that can be addressed to a forensic expert while computer forensic investigation in criminal investigations related to illegal production, manufacture, purchase, storage, transportation, transfer, sale of narcotic drugs, psychotropic substances or their analogues are suggested.

Cloud computing environments add an inherent layer of complication to a digital forensic investigation. The content of this chapter explores current forensic acquisition processes, why current processes need to be modified for cloud investigations, and how new methods can help in an investigation. A section will be included that provides recommendations for more accurate evidence acquisition in investigations. A final section will include recommendations for additional areas of research in the area of investigating cloud computing environments and acquiring cloud computing-based evidence.

The enhancement of technology has led to a considerable amount of growth in number of cases pertaining to cyber-crime and has raised an enormous challenge to tackle it effectively.  There are various cyber forensic techniques and tools used to recover data from the devices to tackle cyber-crime. Present research paper focuses on performing memory forensic and analyzes the memory which contains many pieces of information relevant to forensic investigation, such as username, password, cryptographic keys, deleted files, deleted logs, running processes; that can be helpful to investigate the cyber-crime pining down the accused. The three main steps followed in memory forensic are acquiring, analyzing and recovering. Recovery of the evidences of crime from the volatile memory can be possible with the knowledge of different tools and techniques used in memory forensic.  However, it is always tough to analyze volatile memory as it stays for a very short period. Not all tools can be used for memory forensic in every situation and therefore, it is important to have the knowledge of tools before applying to solve a particular cyber-crime. It is yet to establish on using a single tool for complete investigation, however, most of the tools used are successful in providing reasonable evidences. The present research paper provides an insight on analyzing the memory that stores relevant data, collection of evidences from the device(s), extraction of essential data using different memory forensic tools, tools useful for various purposes and the best suited tool for a particular situation.
