(U//Fouo) Assessment of Anonymous Threat to Control Systems
UNCLASSIFIED//FOR OFFICIAL USE ONLY A‐0020‐NCCIC / ICS‐CERT –120020110916 DISTRIBUTION NOTICE (A): THIS PRODUCT IS INTENDED FOR MISION PARTNERS AT THE “FOR OFFICIAL USE ONLY” LEVEL, ACROSS THE CYBERSECURITY, CRITICAL INFRASTRUCTURE AND / OR KEY RESOURCES COMMUNITY AT LARGE. (U//FOUO) ASSESSMENT OF ANONYMOUS THREAT TO CONTROL SYSTEMS EXECUTIVE SUMMARY (U) The loosely organized hacking collective known as Anonymous has recently expressed an interest in targeting inDustrial control systems (ICS). This proDuct characterizes Anonymous’ capabilities and intent in this area, based on expert input from DHS’s Control Systems Security Program/Industrial Control Systems Cyber Emergency Response Team (ICS‐CERT) in coordination with the other NCCIC components. (U//FOUO) While Anonymous recently expressed intent to target ICS, they have not Demonstrated a capability to inflict Damage to these systems, instead choosing to harass and embarrass their targets using rudimentary attack methoDs, readily available to the research community. Anonymous does have the ability to impact aspects of critical infrastructure that run on common, internet accessible systems (such as web‐based applications and windows systems) by employing tactics such as denial of service. Anonymous’ increased interest may indicate intent to Develop an offensive ICS capability in the future. ICS‐CERT assesses that the publically available information regarding exploitation of ICS coulD be leveraged to reDuce the amount of time to develop offensive ICS capabilities. However, the lack of centralized leadership/coordination anD specific expertise may pose challenges to this effort. DISCUSSION (U//FOUO) Several racist, homophobic, hateful, and otherwise maliciously intolerant cyber and physical inciDents throughout the past Decadea have been attributeD to Anonymous, though recently, their targets and apparent motivations have evolved to what appears to be a hacktivist1 agenda. -

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
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. -

The Process of attempting to gain or successfully gaining, unauthorized access to computer resources Who is a Hacker? In the computer security context, a hacker is someone who seeks and exploits weaknesses in a computer system or computer network. History of Hacking Began as early as 1903: Magician and inventor Nevil Maskelyne disrupts John Ambrose Fleming's public demonstration of Guglielmo Marconi's purportedly secure wireless telegraphy technology, sending insulting Morse code messages through the auditorium's projector The term “Hacker” originated in the 1960’s at MIT A network known as ARPANET was founded by the Department of Defense as a means to link government offices. In time, ARPANET evolved into what is today known as the Internet. -

Any other reproduction or transmission requires prior written permission. Towards Next-Generation Intrusion Detection Robert Koch Institut für Technische Informatik (ITI) Universität der Bundeswehr Munich, Germany [email protected] Abstract- Today, Intrusion Detection Systems (IDS) are integral components of larger networks. Even so, security incidents are on a day-to-day basis: Numerous data leakage scandals arouse public interest in the recent past and also other attacks like Stuxnet are discussed in the general public. On the one side, the commercial success of the Internet and the possibilities to carry out attacks from a relatively safe distance attracts criminals and made e-Crime to a multi-billion dollar market over the past years. On the other side, more and more services and systems migrate to the Internet, for example Voice over IP (VoIP) or Video on Demand (VoD). This enables new and potential attack vectors. With the steadily increasing use of encryption technology, State-of-the-Art Intrusion- as well as Extrusion Detection technologies can hardly safeguard current networks to the full extend. Furthermore, they are not able to cope with the arising challenges of the fast growing network environments. The paper gives an overview of up-to-date security systems and investigates their shortcomings. -
Helpful Definitions
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. -

The team members spend time tracking hackers on the numerous underground hacker forums and marketplaces all over the world. While much of the cybercrime hitting organizations throughout the world is the result of cooperation by hackers working outside the confines of publicly-accessible marketplaces, these underground forums provide a small window into the world cybercriminals occupy. In this report, we concentrated on marketplaces located on the Russian Underground and on English-speaking marketplaces between Q3 2015 and Q1 2016. Just as we did in the 2013 and 2014 Underground Hacker Reports, we wanted to see if any trends had emerged. For example, did prices for popular hacker goods such as stolen bank accounts, credit cards, and malware go up or down? What about services such as Distributed Denial of Service (DDoS) attacks or hacking company databases? Not only did we answer those questions, but we also found some intriguing new products for sale and some interesting new trends as well. -

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.
