UNIVERSIDAD POLITÉCNICA DE MADRID FACULTAD DE INFORMÁTICA TRABAJO FINAL DE CARRERA ESTUDIO DEL PROTOCOLO XMPP DE MESAJERÍA ISTATÁEA, DE SUS ATECEDETES, Y DE SUS APLICACIOES CIVILES Y MILITARES Autor: José Carlos Díaz García Tutor: Rafael Martínez Olalla Madrid, Septiembre de 2008 2 A mis padres, Francisco y Pilar, que me empujaron siempre a terminar esta licenciatura y que tanto me han enseñado sobre la vida A mis abuelos (q.e.p.d.) A mi hijo icolás, que me ha dejado terminar este trabajo a pesar de robarle su tiempo de juego conmigo Y muy en especial, a Susana, mi fiel y leal compañera, y la luz que ilumina mi camino Agradecimientos En primer lugar, me gustaría agradecer a toda mi familia la comprensión y confianza que me han dado, una vez más, para poder concluir definitivamente esta etapa de mi vida. Sin su apoyo, no lo hubiera hecho. En segundo lugar, quiero agradecer a mis amigos Rafa y Carmen, su interés e insistencia para que llegara este momento. Por sus consejos y por su amistad, les debo mi gratitud. Por otra parte, quiero agradecer a mis compañeros asesores militares de Nextel Engineering sus explicaciones y sabios consejos, que sin duda han sido muy oportunos para escribir el capítulo cuarto de este trabajo. Del mismo modo, agradecer a Pepe Hevia, arquitecto de software de Alhambra Eidos, los buenos ratos compartidos alrrededor de nuestros viejos proyectos sobre XMPP y que encendieron prodigiosamente la mecha de este proyecto. A Jaime y a Bernardo, del Ministerio de Defensa, por haberme hecho descubrir las bondades de XMPP. -
There Are Two Dedicated Dspace IRC (Internet Relay Chat) Channels (I.E
IRC Code of Conduct All DSpace support channels, mailing lists and meetings follow the LYRASIS Code of Conduct. We ask you to remain respectful in all discussions. We also encourage you to report any violations of the code of conduct to LYRASIS (see the Code of Conduct for more details). DSpace chat has moved to Slack Our old IRC channels are essentially unmonitored these days. Instead, we recommend joining our DSpace.org Slack for any chat-based support. You are also welcome to email your question to the dspace-tech Mailing List as an alternative, or choose one of the other DSpace Sup port options. There are two dedicated DSpace IRC (internet relay chat) channels (i.e. "rooms") on the irc.freenode.net server: #dspace (irc://irc.freenode.net/dspace) - all DSpace discussions and live Q & A. This channel is unlogged. #duraspace (irc://irc.freenode.net/duraspace) - Old duraspace community channel (no longer used). As of July 2018, this channel is unlogged. Pri or years logs are still available/archived. If you do not have access to an IRC client, or are new to IRC, the following web interfaces are very easy way to get started: Login to #dspace IRC at: http://webchat.freenode.net?channels=dspace Enter in a nickname of your choice (e.g. firstName_lastName) & click "Connect" Login to #duraspace IRC at: http://webchat.freenode.net?channels=duraspace Enter in a nickname of your choice (e.g. firstName_lastName) & click "Connect" Or you can login to both IRC channels at the same time: http://webchat.freenode.net?channels=duraspace,dspace For a list of IRC client software, see: http://en.wikipedia.org/wiki/Comparison_of_Internet_Relay_Chat_clients Many current Instant Messaging (IM) clients also support IRC. -

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. -

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. -
