Desynched Channels on Ircnet
Desynched channels on IRCnet Michael Hansen and Jeroen F. J. Laros [email protected] October 29, 2018 Abstract In this paper we describe what a desynchronised channel on IRC is. We give procedures on how to create such a channel and how to remove desyn- chronisation. We explain which types of desynchronisation there are, what properties desynchronised channels have, and which properties can be ex- ploited. 1 Introduction IRC [1] is one of the oldest digital communication protocols on the internet [2]. This protocol is a form of synchronous conferencing which is mainly used for its one-to-many communication capabilities. Although its popularity has somewhat diminished since the introduction of instant messaging applications [3] like the MSN messenger [4], it is still widely used. In this paper, we first give some background information about IRC in Sec- tion 2. In Section 3 we elaborate on the phenomenon of desynched channels and in Section 4 we describe how to place a boundary, Section 5 covers the occurrence of fake modes and Section 6 describes how to remove a desync. In Section 7, we give some examples of possible uses of fake modes and we conclude in Section 8. arXiv:0811.3140v1 [cs.NI] 19 Nov 2008 2 Background An IRC network consists of multiple servers connected to each other, there are no cycles in this network, so the topology of this network is an undirected tree (acyclic graph). An IRC network also has clients connected to its servers, and messages are relayed from server to server to transfer a message from one client to another. -

Abstract Introduction Methodology
Kajetan Hinner (2000): Statistics of major IRC networks: methods and summary of user count. M/C: A Journal of Media and Culture 3(4). <originally: http://www.api-network.com/mc/0008/count.html> now: http://www.media-culture.org.au/0008/count.html - Actual figures and updates: www.hinner.com/ircstat/ Abstract The article explains a successful approach to monitor the major worldwide Internet Relay Chat (IRC) networks. It introduces a new research tool capable of producing detailed and accurate statistics of IRC network’s user count. Several obsolete methods are discussed before the still ongoing Socip.perl program is explained. Finally some IRC statistics are described, like development of user figures, their maximum count, IRC channel figures, etc. Introduction Internet Relay Chat (IRC) is a text-based service, where people can meet online and chat. All chat is organized in channels which a specific topic, like #usa or #linux. A user can be taking part in several channels when connected to an IRC network. For a long time the only IRC network has been EFnet (Eris-Free Network, named after its server eris.berkeley.edu), founded in 1990. The other three major IRC networks are Undernet (1993), DALnet (1994) and IRCnet, which split off EFnet in June 1996. All persons connecting to an IRC network at one time create that IRC network’s user space. People are constantly signing on and off, the total number of users ever been to a specific IRC network could be called social space of that IRC network. It is obvious, that the IRC network’s social space by far outnumbers its user space. -
Users As Co-Designers of Software-Based Media: the Co-Construction of Internet Relay Chat
Users as Co-Designers of Software-Based Media: The Co-Construction of Internet Relay Chat Guillaume Latzko-Toth Université Laval AbsTrAcT While it has become commonplace to present users as co-creators or “produsers” of digital media, their participation is generally considered in terms of content production. The case of Internet Relay Chat (IRC) shows that users can be fully involved in the design process, a co-construction in the sense of Science and Technology Studies (STS): a collective, simultaneous, and mutual construction of actors and artifacts. A case study of the early de - velopment of two IRC networks sheds light on that process and shows that “ordinary users” managed to invite themselves as co-designers of the socio-technical device. The article con - cludes by suggesting that IRC openness to user agency is not an intrinsic property of software- based media and has more to do with its architecture and governance structure. Keywords Digital media; Communication technology; Co-construction; Design process; Ordinary user résumé Il est devenu banal de présenter l’usager comme cocréateur ou « produtilisateur » des médias numériques, mais sa participation est généralement envisagée comme une production de contenus. Le cas d’IRC (Internet Relay Chat) montre que les usagers des médias à support logiciel peuvent s’engager pleinement dans le processus de conception, une co-construction au sens des Science and Technology Studies : une construction collective, simultanée et mutuelle des acteurs et des artefacts. Une étude de cas portant sur le développement de deux réseaux IRC éclaire ce processus et montre que les « usagers ordinaires » sont parvenus à s’inviter comme co-concepteurs du dispositif. -

A Tool for Internet Chatroom Surveillance
A Tool for Internet Chatroom Surveillance Ahmet C¸amtepe, Mukkai S. Krishnamoorthy, and B¨ulent Yener ? Department of Computer Science, RPI, Troy, NY 12180, USA. {camtes, moorthy, yener}@cs.rpi.edu Abstract. Internet chatrooms are common means of interaction and communications, and they carry valuable information about formal or ad-hoc formation of groups with diverse objectives. This work presents a fully automated surveillance system for data collection and analysis in Internet chatrooms. The system has two components: First, it has an eavesdropping tool which collects statistics on individual (chatter) and chatroom behavior. This data can be used to profile a chatroom and its chatters. Second, it has a computational discovery algorithm based on Singular Value Decomposition (SVD) to locate hidden communities and communication patterns within a chatroom. The eavesdropping tool is used for fine tuning the SVD-based discovery algorithm which can be deployed in real-time and requires no semantic information processing. The evaluation of the system on real data shows that (i) statistical prop- erties of different chatrooms vary significantly, thus profiling is possible, (ii) SVD-based algorithm has up to 70-80% accuracy to discover groups of chatters. 1 Introduction and Background Internet chatrooms provide for an interactive and public forum of communica- tion for participants with diverse objectives. Two properties of chatrooms make them particularly vulnerable for exploitation by malicious parties. First, the real identity of participants are decoupled from their chatroom nicknames. Second, multiple threads of communication can co-exists concurrently. Although human- monitoring of each chatroom to determine who-is-chatting-with-whom is possible, it is very time consuming hence not scalable. -

Back then, online to the average user meant a telephone connection directly to either another computer or to an online service, such as CompuServe or AOL. The Internet now dominates all online activity. In popular parlance, the Internet is synonymous with the World Wide Web, although it is much more, as we’ll explain in this book. The Internet can be described generally as a “network” of networks. It is a transportation vehicle for applications. In fact, the visual representations of the Net look like a road map. If lines are drawn between each connection, between larger and larger connections, and between smaller and smaller ones, the end result is a web of connections—a virtual road map. This book is divided into four rough sections. The first is for beginners. It is to get anyone up to speed quickly with the information needed about the Web. Each chapter has recommended Web sites (to type the address, or Uniform Resource Locator [URL] into your Web browser) to help direct you. The second section has more detailed information about downloads, email, secu- rity, and information on virus protection. The third part is about how to create a Web site, Web tools, blogging, and what you can add to your Web site (such as streaming media, RSS feeds, and XML, among other things). The fourth part is by far the densest. -

Distributed under a Creative Commons Attribution| 4.0 International License Chapter 3 AUTOMATED ANALYSIS OF UNDERGROUND MARKETPLACES Aleksandar Hudic, Katharina Krombholz, Thomas Otterbein, Christian Platzer and Edgar Weippl Abstract Cyber criminals congregate and operate in crowded online underground marketplaces. Because forensic investigators lack efficient and reliable tools, they are forced to analyze the marketplace channels manually to locate criminals – a complex, time-consuming and expensive task. This paper demonstrates how machine learning algorithms can be used to automatically determine if a communication channel is used as an underground marketplace. Experimental results demonstrate that the classification system, which uses features related to the cyber crime do- main, correctly classifies 51.3 million messages.
