ABSTRACT The motivation for pursuing XML-based tactical chat includes the great potential of this technology and fixing limitations of current chat programs. XTC capabilities have the potential to completely upgrade and restructure all tactical military communications. The current tools for military chat include IRC, Yahoo, MSN, AIM, ICQ, and NKO. None of these provides the full functionality or interoperability needed in a joint environment. Moreover, if a nonproprietary chat protocol is developed, it can lead to a decision-support environment in which data, text, audio, and video can be logged, evaluated and managed, all in a Web environment where no additional specialized software or hardware is needed. Chat technology challenges for the military fit into three areas: tactical, technical, and administrative. Tactically, there are many ways chat can be used, but effective practices are not yet defined in procedures or doctrine. Joint forces use a myriad of chat programs that don’t interoperate and are usually proprietary. Technically, many chat programs are barred by firewalls and lack a robust interface to allow logging and searching past chats. From an administrative prospective, plain-text chat has no structure. Scheduling and controlling who attends or converses remains undefined. Within DoD there is no standard for how, when, and by whom chats ought to be conducted. Possible approaches to these problems include adopting a proprietary chat system or customizing an open-source implementation. Proprietary solutions are costly, do not interoperate well, and are too inflexible for a technology that is evolving rapidly. Open-source software can provide a solution that is adaptable, extensible, quick to implement, straightforward to maintain, and relatively inexpensive. This thesis provides a preliminary assessment of XML-based tactical chat (XTC) using an open- source, open-standards solution. Promising initial results demonstrate that an XML document can be sent from a XHTML page in a Web browser to an off-the-shelf Jabber client via a Web server. Further, available server and client implementations can enable a research and development plan for rapid development. 14. SUBJECT TERMS XML, Tactical chat, XML, Jabber, XHTML, XTC, IRC 15.

    DETECTING BOTS in INTERNET CHAT by SRITI KUMAR Under The

    DETECTING BOTS IN INTERNET CHAT by SRITI KUMAR (Under the Direction of Kang Li) ABSTRACT Internet chat is a real-time communication tool that allows on-line users to communicate via text in virtual spaces, called chat rooms or channels. The abuse of Internet chat by bots also known as chat bots/chatterbots poses a serious threat to the users and quality of service. Chat bots target popular chat networks to distribute spam and malware. We first collect data from a large commercial chat network and then conduct a series of analysis. While analyzing the data, different patterns were detected which represented different bot behaviors. Based on the analysis on the dataset, we proposed a classification system with three main components (1) content- based classifiers (2) machine learning classifier (3) communicator. All three components of the system complement each other in detecting bots. Evaluation of the system has shown some measured success in detecting bots in both log-based dataset and in live chat rooms. INDEX WORDS: Yahoo!

  • Expectation of Privacy in Internet Communications

    Expectation of Privacy in Internet Communications

    Fourth Amendment Aspects of Internet Communications and Technology Dennis Nicewander Assistant State Attorney 17th Judicial Circuit Ft. Lauderdale, Florida The emergence of Internet technology has revolutionized the world of communication and information sharing. Unfortunately, criminals have seized this opportunity to enhance the efficiency and productivity of their criminal pursuits. The task ahead of law enforcement is daunting, to say the least. New forms of technology emerge before we are able to master the old ones. The most significant legal issue to arise in this struggle to make order out of chaos is the application of the Fourth Amendment to these emerging technologies. If our economy is going to continue to grow at the rapid pace promised by Internet technology, we must find a way to balance our citizens‟ right to privacy with the necessity of establishing law and order in this new frontier. As our culture and legal system suffer the growing pains of radical change, it is responsibility of prosecutors to work together with law enforcement to strike a balance between effective police work and privacy rights afforded by the Fourth Amendment. Understanding the role of “reasonable expectation of privacy” is critical to this role. Since most information placed on the Internet is designed for mass distribution, a reasonable expectation of privacy will not apply in the majority of cases. The purpose of this paper is to provide basic guidance and case law concerning this issue as it relates to some of the most common forms Internet technology. The topics will be divided into the following categories: General Privacy Cases Email Chatrooms Peer-to-Peer Internet Service Provider Records Websites Bulletin Boards University Usage Logs Text Messages General Privacy Cases Katz v.

    HELPFUL DEFINITIONS Internet – an immense, global network that connects computers via telephone lines and/or fiber networks to storehouses of electronic information. With only a computer, a modem, a telephone line and a service provider, people from all over the world can communicate and share information with little more than a few keystrokes. Bulletin Board Systems (BBSs) – electronic networks of computers that are connected by a central computer setup and operated by a system administrator or operator and are distinguishable from the internet by their “dial up” accessibility. BBS users link their individual computers to the central BBS computer by a modem which allows them to post messages, read messages left by others, trade information, or hold direct conversations. Access to a BBS can, and often is, privileged and limited to those users who have access privileges granted by the systems operator. Commercial Online Service (COS) – examples of COSs are America Online, Prodigy, CompuServe and Microsoft Network, which provide access to their service for a fee. COSs generally offer limited access to the internet as part of their total service package. Internet Service Provider (ISP) – These services offer direct, full access to the internet at a flat, monthly rate and often provide electronic mail service for their customers. ISPs often provide space on their servers for their customers to maintain World Wide Web (WWW) sites. Not all ISPs are commercial enterprises. Educational, governmental and nonprofit organizations also provide internet access to their members. Public Chat Rooms – created, maintained, listed and monitored by the COS and other public domain systems such as Internet Relay Chat.

Though there are plenty of other voice and video chat offerings available for computers and smartphones, AV is unlike many with its decision to eschew both logins and software downloads. In order to start a chat, a user gets a unique link from AV and sends it to friends. Once a friend with a webcam clicks on the link, a chat window will pop up on the screen and show live video of the user who started the chat session and any other participants. Up to four people can be involved in a chat at once, Shellen said. The service has several features, such as the ability to type messages to individual users while video chatting - to send a link to a webpage, for example.

    Attitude Adjustment: Trojans and Malware on the Internet An Update Sarah Gordon and David Chess IBM Thomas J. Watson Research Center Yorktown Heights, NY Abstract This paper continues our examination of Trojan horses on the Internet; their prevalence, technical structure and impact. It explores the type and scope of threats encountered on the Internet - throughout history until today. It examines user attitudes and considers ways in which those attitudes can actively affect your organization’s vulnerability to Trojanizations of various types. It discusses the status of hostile active content on the Internet, including threats from Java and ActiveX, and re-examines the impact of these types of threats to Internet users in the real world. Observations related to the role of the antivirus industry in solving the problem are considered. Throughout the paper, technical and policy based strategies for minimizing the risk of damage from various types of Trojan horses on the Internet are presented This paper represents an update and summary of our research from Where There's Smoke There's Mirrors: The Truth About Trojan Horses on the Internet, presented at the Eighth International Virus Bulletin Conference in Munich Germany, October 1998, and Attitude Adjustment: Trojans and Malware on the Internet, presented at the European Institute for Computer Antivirus Research in Aalborg, Denmark, March 1999. Significant portions of those works are included here in original form.

One way to fight cybercrime is to collect digital evidence from online documents and to prosecute cybercriminals in the court of law. In this paper, we propose a unified framework using data mining and natural language processing techniques to analyze online messages for the purpose of crime investigation. Our framework takes the chat log from a confiscated computer as input, extracts the social networks from the log, summarizes chat conversations into topics, identifies the information relevant to crime investigation, and visualizes the knowledge for an investigator. To ensure that the implemented framework meets the needs of law enforcement officers in real-life investigation, we closely collaborate with the cybercrime unit of a law enforcement agency in Canada. Both the feedback from the law enforcement officers and experimental results suggest that the proposed chat log mining framework is effective for crime Fig. 1. Framework overview investigation.
