The Evolving Landscape of Internet Control

Over the past two years, we have undertaken several studies at the Berkman Center designed to better understand the control of the Internet in less open societies. During the years we've been engaged in this research, we have seen many incidents that have highlighted the continuing role of the Internet as a battleground for political control, including partial or total Internet shutdowns in China, Iran, Egypt, Libya, and Syria; many hundreds of documented DDoS, hacking, and other cyber attacks against political sites; continued growth in the number of countries that filter the Internet; and dozens of well documented cases of on- and offline persecution of online dissidents. The energy dedicated to these battles for control of the Internet on both the government and dissident sides indicated, if nothing else, that both sides think that the Internet is a critical space for political action. In this paper, we offer an overview of our research in the context of these changes in the methods used to control online speech, and some thoughts on the challenges to online speech in the immediate future

Online Security in the Middle East and North Africa: A Survey of Perceptions, Knowledge, and Practice

Digital communication has become a more perilous activity, particularly for activists, political dissidents, and independent media. The recent surge in digital activism that has helped to shape the Arab spring has been met with stiff resistance by governments in the region intent on reducing the impact of digital organizing and independent media. No longer content with Internet filtering, many governments in the Middle East and around the world are using a variety of technological and offline strategies to go after online media and digital activists. In Tunisia, before and during the January 2011 protest movement that led to a change in government there, Internet service providers were apparently logging usernames and passwords to hack into and dismantle online organizing and information sharing among protesters. In early June 2011, Google reported a phishing attack targeted at military and human rights activists to gain access to their Gmail accounts. In Syria, a well organized effort known as the Syrian Electronic Army has been carrying out attacks to disable and compromise web sites that are critical of the Syrian regime. These stories are only a few selected from the set that have become public, and an unknown number of attacks go unnoticed and unreported. Many of these attacks are impossible to attribute to specific actors and may involve a mix of private sector and governmental actors, blurring the lines between cyber attacks and government surveillance. In such an environment, maintaining online security is a growing challenge.In this report we describe the results of a survey of 98 bloggers in the Middle East and North Africa (MENA) carried out in May 2011 in order to study bloggers' perceptions of online risk and the actions they take to address digital communications security, including both Internet and cell phone use. The survey was implemented in the wake of the Arab spring and documents a proliferation of online security problems among the respondents. In the survey, we address the respondents' perceptions of online risk, their knowledge of digital security practices, and their reported online security practices. The survey results indicate that there is much room for improving online security practices, even among this sample of respondents who are likely to have relatively high technical knowledge and experience

Network Propaganda

"Is social media destroying democracy? Are Russian propaganda or ""Fake news"" entrepreneurs on Facebook undermining our sense of a shared reality? A conventional wisdom has emerged since the election of Donald Trump in 2016 that new technologies and their manipulation by foreign actors played a decisive role in his victory and are responsible for the sense of a ""post-truth"" moment in which disinformation and propaganda thrives. Network Propaganda challenges that received wisdom through the most comprehensive study yet published on media coverage of American presidential politics from the start of the election cycle in April 2015 to the one year anniversary of the Trump presidency. Analysing millions of news stories together with Twitter and Facebook shares, broadcast television and YouTube, the book provides a comprehensive overview of the architecture of contemporary American political communications. Through data analysis and detailed qualitative case studies of coverage of immigration, Clinton scandals, and the Trump Russia investigation, the book finds that the right-wing media ecosystem operates fundamentally differently than the rest of the media environment. The authors argue that longstanding institutional, political, and cultural patterns in American politics interacted with technological change since the 1970s to create a propaganda feedback loop in American conservative media. This dynamic has marginalized centre-right media and politicians, radicalized the right wing ecosystem, and rendered it susceptible to propaganda efforts, foreign and domestic. For readers outside the United States, the book offers a new perspective and methods for diagnosing the sources of, and potential solutions for, the perceived global crisis of democratic politics.

Exploring Russian Cyberspace: Digitally-Mediated Collective Action and the Networked Public Sphere

This paper summarizes the major findings of a three-year research project to investigate the Internet's impact on Russian politics, media and society. We employed multiple methods to study online activity: the mapping and study of the structure, communities and content of the blogosphere; an analogous mapping and study of Twitter; content analysis of different media sources using automated and human-based evaluation approaches; and a survey of bloggers; augmented by infrastructure mapping, interviews and background research. We find the emergence of a vibrant and diverse networked public sphere that constitutes an independent alternative to the more tightly controlled offline media and political space, as well as the growing use of digital platforms in social mobilization and civic action. Despite various indirect efforts to shape cyberspace into an environment that is friendlier towards the government, we find that the Russian Internet remains generally open and free, although the current degree of Internet freedom is in no way a prediction of the future of this contested space

2010 Circumvention Tool Usage Report

Circumvention tools allow users to bypass Internet filtering to access content otherwise blocked by governments, workplaces, schools, or even the blocked sites themselves. There are a number of different types of these tools: blocking-resistant tools, simple web proxies, virtual private network (VPN) services, and open HTTP/SOCKS proxies. But every type of circumvention tool provides the same basic functionality — proxying user connections to provide access to otherwise blocked sites. In the following report, we use a variety of methods to evaluate the usage of the first three of these four types of tools to test two hypotheses. First, even though much of the media attention on circumvention tools has been given to a handful of tools — notably Freegate, Ultrasurf, Tor, and Hotspot Shield — we find that these tools represent only a small portion of overall circumvention usage and that the attention paid to these tools has been disproportionate to their usage, especially when compared to the more widely used simple web proxies. Second, even when including the more widely-used simple web proxies, we find that overall usage of circumvention tools is still very small in proportion to the number of Internet users in countries with substantial national Internet filtering

Bohr-Sommerfeld Quantization of Space

We introduce semiclassical methods into the study of the volume spectrum in loop gravity. The classical system behind a 4-valent spinnetwork node is a Euclidean tetrahedron. We investigate the tetrahedral volume dynamics on phase space and apply Bohr-Sommerfeld quantization to find the volume spectrum. The analysis shows a remarkable quantitative agreement with the volume spectrum computed in loop gravity. Moreover, it provides new geometrical insights into the degeneracy of this spectrum and the maximum and minimum eigenvalues of the volume on intertwiner space.Comment: 32 pages, 10 figure

Explorando o Ciberespaço Russo: Ação Coletiva Digitalmente Mediada e a Esfera Pública Interconectada

Propósito – Este artigo sintetiza os principais achados de um projeto de pesquisa de três anos para investigar o impacto da Internet sobre a política, a mídia e a sociedade russa. Metodologia/abordagem/design – Empregamos múltiplos métodos para estudar atividades online: o mapeamento e estudo da estrutura, das comunidades e do conteúdo da blogosfera; um análogo mapeamento e estudo do Twitter; a análise de conteúdo de diferentes fontes midiáticas, utilizando tanto abordagens automatizadas quanto abordagens baseadas em avaliação humana; e uma enquete com blogueiros; métodos esses expandidos por mapeamento de infraestrutura, por entrevistas e por investigações de contexto. Resultados – Constatamos a emergência de uma vibrante e diversa esfera pública interconectada, que constitui uma alternativa independente ao mais rigidamente controlado espaço midiático e político offline, e verificamos o uso crescente de plataformas digitais na mobilização social e na ação cívica. Implicações práticas – Apesar da existência de vários esforços indiretos para conformar o ciberespaço como um ambiente mais amigável ao governo, constatamos que a Internet russa permanece, em geral, aberta e livre, embora o atual grau de liberdade na Internet de forma alguma possa representar previsão acerca do futuro desse espaço contestado
