This article examines a set of interactions (logs) takenfrom t h e f a n of computer-mediated communicntion known as Internet Relay Chat (IRC). The authors were particularly concerned with the interaction management strategies adopted by the participants in the logs during the opening and closing phases of the interactions to d m l o p interpersonal relationships and communicate socioemotional ...

To further cybersecurity, there is interest in studying online cybercriminal communities to learn more about emerging cyber threats. Literature documents the existence of many online Internet Relay Chat (IRC) cybercriminal communities where cybercriminals congregate and share hacking tools, malware, and more. However, many cybercriminal community participants appear unskilled and have fleeting ...

Overview This design project addresses the inherent ambiguities of text chat interfaces concerning which messages relate to which. Due to their linear nature, the relationship between two messages is not always obvious. A prototype of an application has been developed that allows users to structure their conversations in a mindmap or tree layout. Its use of space and color is designed to make i...

Social patterns are observable in real-world interactions as visual cues. Online, however, there are few visual cues available that can be used to see and understand social patterns. In this thesis, I suggest that many of these social patterns are still present in our interactions online in text chat; they are merely encoded in the textual interactions. This thesis presents Coterie, a visualiza...

This paper presents a new hierarchical distributed communication architecture, called AHS (Auction Handling System), based on clusters. This architecture uses the IRC (Internet Relay Chat) channels and protocol facilities in order to support real-time auction applications (RTA). Coordination between distributed auction servers is needed to exchange and update some relevant auction information a...

Over the last few years, researchers and network operators have examined networks of DDoS agents, more recently called botnets due to their connection to Internet Relay Chat (IRC). In the continued quest to take down these networks of bots, two important questions arise: how many bots are there, and how to find every last bot? When one reads about a ten thousand, hundred thousand, one million n...

In this paper, we apply social network analytic methods to unveil the structural dynamics of a popular open source goal oriented IRC community, Ubuntu. The primary objective is to track the development of this ever growing community over time using a social network lens and examine the dynamically changing participation patterns of people. Specifically, our research seeks out to investigate ans...

For a long time, dialogue analysis has separated spoken language from written language. This dichotomy is valid in many cases as it is mostly parallel to the distinction of synchronous and asynchronous communication with the associated affinity to graphic and acoustic media, respectively. During the present decade, many forms of computer mediated communication (CMC) have become widespread. With...

To date, techniques to counter cyber-attacks have predominantly been reactive; they focus on monitoring network traffic, detecting anomalies and cyber-attack traffic patterns, and, a posteriori, combating the cyber-attacks and mitigating their effects. Contrary to such approaches, we advocate proactively detecting and identifying botnets prior to their being used as part of a cyber-attack [12]....
