Anonymizing 1 Your Activities In our daily lives we like to have a certain level of privacy. We have curtains on our win- dows, doors for our offices, and even special screen protectors for computers to keep out prying eyes. This idea of wanting privacy also extends to the use of the Internet. We do not want people knowing what we typed in Google, what we said in our Instant Message conversations, or what websites we visited. Unfortunately, your private information is largely available if someone is watching. When doing any number of things on the Internet, there are plenty of reasons you might want to go incognito. However, that does not mean you’re doing anything wrong or illegal. he justification for anonymity when researching malware and bad guys is pretty Tstraightforward. You do not want information to show up in logs and other records that might tie back to you or your organization. For example, let’s say you work at a finan- cial firm and you recently detected that a banking trojan infected several of your systems. You collected malicious domain names, IP addresses, and other data related to the malware. The next steps you take in your research may lead you to websites owned by the criminals. As a result, if you are not taking precautions to stay anonymous, your IP address will show up in various logs and be visible to miscreants. If the criminals can identify you or the organization from which you conduct your research, they may COPYRIGHTEDchange tactics or go into hiding, MATERIAL thus spoiling your investigation. -
Low-Cost Traffic Analysis Of
Low-Cost Traffic Analysis of Tor Steven J. Murdoch and George Danezis University of Cambridge, Computer Laboratory 15 JJ Thomson Avenue, Cambridge CB3 0FD United Kingdom {Steven.Murdoch,George.Danezis}@cl.cam.ac.uk Abstract Other systems, based on the idea of a mix, were de- veloped to carry low latency traffic. ISDN mixes [33] Tor is the second generation Onion Router, supporting propose a design that allows phone conversations to be the anonymous transport of TCP streams over the Inter- anonymised, and web-mixes [6] follow the same design pat- net. Its low latency makes it very suitable for common terns to anonymise web traffic. A service based on these tasks, such as web browsing, but insecure against traffic- ideas, the Java Anon Proxy (JAP)1 has been implemented analysis attacks by a global passive adversary. We present and is running at the University of Dresden. These ap- new traffic-analysis techniques that allow adversaries with proaches work in a synchronous fashion, which is not well only a partial view of the network to infer which nodes are adapted for the asynchronous nature of widely deployed being used to relay the anonymous streams and therefore TCP/IP networks [8]. greatly reduce the anonymity provided by Tor. Furthermore, The Onion Routing project has been working on stream- we show that otherwise unrelated streams can be linked level, low-latency, high-bandwidth anonymous communi- back to the same initiator. Our attack is feasible for the cations [35]. Their latest design and implementation, adversary anticipated by the Tor designers.

DNS Spoofing 2
Professor Vahab COMP 424 13 November 2016 DNS Spoofing DNS spoofing, also known as DNS Cache Poisoning, is one of the most widely used man-in-the-middle attacks that capitalizes on vulnerabilities in the domain name system that returns a false IP address and routes the user to a malicious domain. Whenever a machine contacts a domain name such as www.bankofamerica.com, it must first contact its DNS server which responds with multiple IP addresses where your machine can reach the website. Your computer is then able to connect directly to one of the IP addresses and the DNS is able to convert the IP addresses into a human-readable domain name. If an attacker is able to gain control of a DNS server and change some of its properties such as routing Bank of America’s website to an attacker’s IP address. At that location, the attacker is then able to unsuspectingly steal the user’s credentials and account information. Attackers use spam and other forms of attack to deliver malware that changes DNS settings and installs a rogue Certificate Authority. The DNS changes point to the hacker's secret DNS name server so that when the users access the web they are directed to proxy servers instead of authorized sites. They can also start to blacklist domains and frustrate the user with their day to day activities. All blacklisted domains would have their traffic dropped instead of forwarded to their intended destination. Based on the rogue Certificate Authority the system has no sign that an attack is taking place or ever took place. -
Secure Shell- Its Significance in Networking (Ssh)
International Journal of Application or Innovation in Engineering & Management (IJAIEM) Web Site: www.ijaiem.org Email: [email protected] Volume 4, Issue 3, March 2015 ISSN 2319 - 4847 SECURE SHELL- ITS SIGNIFICANCE IN NETWORKING (SSH) ANOOSHA GARIMELLA , D.RAKESH KUMAR 1. B. TECH, COMPUTER SCIENCE AND ENGINEERING Student, 3rd year-2nd Semester GITAM UNIVERSITY Visakhapatnam, Andhra Pradesh India 2.Assistant Professor Computer Science and Engineering GITAM UNIVERSITY Visakhapatnam, Andhra Pradesh India ABSTRACT This paper is focused on the evolution of SSH, the need for SSH, working of SSH, its major components and features of SSH. As the number of users over the Internet is increasing, there is a greater threat of your data being vulnerable. Secure Shell (SSH) Protocol provides a secure method for remote login and other secure network services over an insecure network. The SSH protocol has been designed to support many features along with proper security. This architecture with the help of its inbuilt layers which are independent of each other provides user authentication, integrity, and confidentiality, connection- oriented end to end delivery, multiplexes encrypted tunnel into several logical channels, provides datagram delivery across multiple networks and may optionally provide compression. Here, we have also described in detail what every layer of the architecture does along with the connection establishment. Some of the threats which Ssh can encounter, applications, advantages and disadvantages have also been mentioned in this document. Keywords: SSH, Cryptography, Port Forwarding, Secure SSH Tunnel, Key Exchange, IP spoofing, Connection- Hijacking. 1. INTRODUCTION SSH Secure Shell was first created in 1995 by Tatu Ylonen with the release of version 1.0 of SSH Secure Shell and the Internet Draft “The SSH Secure Shell Remote Login Protocol”. -
Design of a Blocking-Resistant Anonymity System DRAFT
Design of a blocking-resistant anonymity system DRAFT Roger Dingledine Nick Mathewson The Tor Project The Tor Project [email protected] [email protected] Abstract Internet censorship is on the rise as websites around the world are increasingly blocked by government-level firewalls. Although popular anonymizing networks like Tor were originally designed to keep attackers from tracing people’s activities, many people are also using them to evade local censorship. But if the censor simply denies access to the Tor network itself, blocked users can no longer benefit from the security Tor offers. Here we describe a design that builds upon the current Tor network to provide an anonymiz- ing network that resists blocking by government-level attackers. 1 Introduction and Goals Anonymizing networks like Tor [11] bounce traffic around a network of encrypting relays. Unlike encryption, which hides only what is said, these networks also aim to hide who is communicat- ing with whom, which users are using which websites, and similar relations. These systems have a broad range of users, including ordinary citizens who want to avoid being profiled for targeted advertisements, corporations who don’t want to reveal information to their competitors, and law en- forcement and government intelligence agencies who need to do operations on the Internet without being noticed. Historical anonymity research has focused on an attacker who monitors the user (call her Alice) and tries to discover her activities, yet lets her reach any piece of the network. In more modern threat models such as Tor’s, the adversary is allowed to perform active attacks such as modifying communications to trick Alice into revealing her destination, or intercepting some connections to run a man-in-the-middle attack. -
Everyone's Guide to Bypassing Internet Censorship
EVERYONE’S GUIDE TO BY-PASSING INTERNET CENSORSHIP FOR CITIZENS WORLDWIDE A CIVISEC PROJECT The Citizen Lab The University of Toronto September, 2007 cover illustration by Jane Gowan Glossary page 4 Introduction page 5 Choosing Circumvention page 8 User self-assessment Provider self-assessment Technology page 17 Web-based Circumvention Systems Tunneling Software Anonymous Communications Systems Tricks of the trade page 28 Things to remember page 29 Further reading page 29 Circumvention Technologies Circumvention technologies are any tools, software, or methods used to bypass Inter- net filtering. These can range from complex computer programs to relatively simple manual steps, such as accessing a banned website stored on a search engine’s cache, instead of trying to access it directly. Circumvention Providers Circumvention providers install software on a computer in a non-filtered location and make connections to this computer available to those who access the Internet from a censored location. Circumvention providers can range from large commercial organi- zations offering circumvention services for a fee to individuals providing circumven- tion services for free. Circumvention Users Circumvention users are individuals who use circumvention technologies to bypass Internet content filtering. 4 Internet censorship, or content filtering, has become a major global problem. Whereas once it was assumed that states could not control Internet communications, according to research by the OpenNet Initiative (http://opennet.net) more than 25 countries now engage in Internet censorship practices. Those with the most pervasive filtering policies have been found to routinely block access to human rights organi- zations, news, blogs, and web services that challenge the status quo or are deemed threatening or undesirable. -
Promoting Global Internet Freedom: Government and Industry Initiatives
Promoting Global Internet Freedom: Government and Industry Initiatives (name redacted) Specialist in Internet and Telecommunications Policy June 1, 2016 Congressional Research Service 7-.... www.crs.gov R41837 Promoting Global Internet Freedom: Government and Industry Initiatives Summary Modern communication tools such as the Internet provide a relatively inexpensive, accessible, easy-entry means of sharing ideas, information, and pictures around the world. In a political and human rights context, in closed societies when the more established, formal news media is denied access to or does not report on specified news events, the Internet has become an alternative source of media, and sometimes a means to organize politically. The openness and the freedom of expression allowed through social networking sites, as well as the blogs, video sharing sites, and other tools of today’s communications technology, have proven to be an unprecedented and often disruptive force in some closed societies. Governments that seek to maintain their authority and control the ideas and information their citizens receive are often caught in a dilemma: they feel that they need access to the Internet to participate in commerce in the global market and for economic growth and technological development, but fear that allowing open access to the Internet potentially weakens their control over their citizens. Internet freedom can be promoted in two ways, through legislation that mandates or prohibits certain activities, or through industry self-regulation. Past legislation has been aimed at prohibiting or requiring the reporting of the sale of Internet technologies and provision of Internet services to “Internet-restricting countries” (as determined by the State Department). -
Threat Modeling and Circumvention of Internet Censorship by David Fifield
Threat modeling and circumvention of Internet censorship By David Fifield A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Computer Science in the Graduate Division of the University of California, Berkeley Committee in charge: Professor J.D. Tygar, Chair Professor Deirdre Mulligan Professor Vern Paxson Fall 2017 1 Abstract Threat modeling and circumvention of Internet censorship by David Fifield Doctor of Philosophy in Computer Science University of California, Berkeley Professor J.D. Tygar, Chair Research on Internet censorship is hampered by poor models of censor behavior. Censor models guide the development of circumvention systems, so it is important to get them right. A censor model should be understood not just as a set of capabilities|such as the ability to monitor network traffic—but as a set of priorities constrained by resource limitations. My research addresses the twin themes of modeling and circumvention. With a grounding in empirical research, I build up an abstract model of the circumvention problem and examine how to adapt it to concrete censorship challenges. I describe the results of experiments on censors that probe their strengths and weaknesses; specifically, on the subject of active probing to discover proxy servers, and on delays in their reaction to changes in circumvention. I present two circumvention designs: domain fronting, which derives its resistance to blocking from the censor's reluctance to block other useful services; and Snowflake, based on quickly changing peer-to-peer proxy servers. I hope to change the perception that the circumvention problem is a cat-and-mouse game that affords only incremental and temporary advancements. -

Governments are wary of these men and women, who are posting news, without being professional journalists. Worse, bloggers sometimes raise sensitive issues which the media, now known as "tradition- al", do not dare cover. Blogs have in some countries become a source of news in their own right. Nearly 120,000 blogs are created every day. Certainly the blogosphere is not just adorned by gems of courage and truth.
