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. -

A Privacy Threat for Internet Users in Internet-Censoring Countries
A Privacy Threat for Internet Users in Internet-censoring Countries Feno Heriniaina R. College of Computer Science, Chongqing University, Chongqing, China Keywords: Censorship, Human Computer Interaction, Privacy, Virtual Private Networks. Abstract: Online surveillance has been increasingly used by different governments to control the spread of information on the Internet. The magnitude of this activity differs widely and is based primarily on the areas that are deemed, by the state, to be critical. Aside from the use of keywords and the complete domain name filtering technologies, Internet censorship can sometimes even use the total blocking of IP addresses to censor content. Despite the advances, in terms of technology used for Internet censorship, there are also different types of circumvention tools that are available to the general public. In this paper, we report the results of our investigation on how migrants who previously had access to the open Internet behave toward Internet censorship when subjected to it. Four hundred and thirty-two (432) international students took part in the study that lasted two years. We identified the most common circumvention tools that are utilized by the foreign students in China. We investigated the usability of these tools and monitored the way in which they are used. We identified a behaviour-based privacy threat that puts the users of circumvention tools at risk while they live in an Internet-censoring country. We also recommend the use of a user-oriented filtering method, which should be considered as part of the censoring system, as it enhances the performance of the screening process and recognizes the real needs of its users. -

The Impact of Media Censorship: Evidence from a Field Experiment in China
The Impact of Media Censorship: Evidence from a Field Experiment in China Yuyu Chen David Y. Yang* January 4, 2018 — JOB MARKET PAPER — — CLICK HERE FOR LATEST VERSION — Abstract Media censorship is a hallmark of authoritarian regimes. We conduct a field experiment in China to measure the effects of providing citizens with access to an uncensored Internet. We track subjects’ me- dia consumption, beliefs regarding the media, economic beliefs, political attitudes, and behaviors over 18 months. We find four main results: (i) free access alone does not induce subjects to acquire politically sen- sitive information; (ii) temporary encouragement leads to a persistent increase in acquisition, indicating that demand is not permanently low; (iii) acquisition brings broad, substantial, and persistent changes to knowledge, beliefs, attitudes, and intended behaviors; and (iv) social transmission of information is statis- tically significant but small in magnitude. We calibrate a simple model to show that the combination of low demand for uncensored information and the moderate social transmission means China’s censorship apparatus may remain robust to a large number of citizens receiving access to an uncensored Internet.

The Question of State Sponsored Cyber Terrorism and Espionage Student Officer
st th The Hague International Model United Nations Qatar 2020 | 21 – 24 of January 2020 Forum: The Security Council Issue: The Question of State sponsored cyber terrorism and espionage Student Officer: Sebastian Santoni Position: President Introduction On the 27th of April 2007, Estonia experienced the first of a series of cyber attacks which would go on to shape laws, policies, and attitudes within and outside its borders. The country was bombarded by thousands of independent actors, resulting in the complete loss of most internet services for three weeks. The Estonian parliament, banks and media were all targeted in the midst of political disagreements with Russia. Although not the first incident of cyber terrorism, this was definitely one of the most destructive, managing to make an entire country go offline. In response, the world’s first ever regulations concerning actions in cyberspace were drafted, hoping to prevent such incidents from occurring in the future. However, incidents of cyber terrorism and espionage continued and remain a major threat to international security. Not only can they create mistrust and paranoia between nations, but also paralyse the organizations and resources core to their economic, social and political stability. This is especially true when such acts are initiated by countries and their related bodies, placing the world’s most sophisticated technology in the wrong hands. As members of the United Nations, it is the responsibility of countries to use their resources, voices and cooperation to strengthen international cyber security and work towards a world where state-sponsored cyber terrorism and espionage are void. Organizations such as the Kaspersky Lab and the Cooperative Cyber Defence Center of Excellence have made strides toward combating the issue, although they are restricted by an acute lack of relevant treaties and laws. -
