Production of Solidarities in YouTube : a Visual Study of Uyghur Nationalism
2013 Vergani, M. and Zuev, D. Chapter
Neo-Jihadist Prosumers and Al Qaeda Single Narrative: The Case Study of Giuliano Delnevo
2014 Vergani, M. Journal
Scholars in the field of terrorism and violent extremism often refer to the so-called Al
Qaeda single narrative. This article suggests that the Internet challenges the existence of
a “single narrative,” by arguing that neo-jihadist prosumers may reinterpret Al Qaeda’s
narrative and create hybrid symbols and identities. The article discusses the case study of
an Italian neo-jihadist allegedly killed in Syria, Giuliano Delnevo, presenting research
on his YouTube and Facebook production. Delnevo’s narrative, which emerges from
the diverse messages circulating on the Internet, recasts the Al Qaeda narrative by
hybridizing it with other cultural backgrounds and political symbols.
Neojihadist Visual Politics: Comparing YouTube Videos of North Caucasus and Uyghur Militants
2014 Vergani, M. and Zuev, D. Journal
Analysis of YouTube Videos Used by Activists in the Uyghur Nationalist Movement: combining quantitative and qualitative methods
2011 Vergani, M. and Zuev, D. Journal
This paper explores the uses of YouTube by Uyghur nationalist movement activists and studies various ideological codes used by different communities to promote their messages. It argues that several ideological codes are produced in order to challenge the dominant ideologies promoted by the Chinese government, which create a ground for Uyghur ‘imagined solidarity’ across physical borders. Analysis of the production of audio-visual messages by the dispersed ethnic group provides an important window into how ethnic identity is forged by means of Web 2.0.
Sentiment-Based Identification of Radical Authors (SIRA).
2015 Scrivens, R., Davies, G., Frank, R. and Mei, J. Article
Picture Or It Didn’t Happen: A Snapshot of the Islamic State’s Official Media Output
2015 Zelin, A.Y. Journal
This article seeks to examine, quantitatively and qualitatively, one week of official media releases of the Islamic State (IS). Due to the breadth of IS official media releases, this provides a snapshot upon which to better understand the different styles and messaging streams IS releases on a weekly basis. The article shows that IS produces much more material, and on a broader range of topics, than what gets reported in the mainstream media. Execution videos make up just a fraction of the overall output and are dwarfed by the number of IS productions on military affairs, governance, preaching, moral policing, and other themes. The analysis also shows that IS relies very heavily on visual as opposed to text-based propaganda, and that most of its military activities take place in Iraq, not Syria.
The Internet: A Virtual Training Camp?
2008 Stenersen, A. Journal
This study aims to investigate how Al Qaeda uses the Internet for military training and preparation. What kind of training material is available on jihadi webpages, who produces it, and for what purpose? The article argues that in spite of a vast amount of training-related literature online, there have been few organized efforts by Al Qaeda to train their followers by way of the Internet. The Internet is per today not a “virtual training camp” organized from above, but rather a resource bank maintained and accessed largely by self-radicalized sympathizers.
Terror in Cyberspace Terrorists Will Exploit and Widen the Gap Between Governing Structures and the Public
2002 Stanton, J.J. Journal
There is an inverse relationship between public access to the Internet and the inability of governments and institutions to control information flow and hence state allegiance, ideology, public opinion, and policy formulation. Increase in public access to the Internet results in an equivalent decrease in government and institutional power. Indeed, after September 11, 2001, Internet traffic statistics show that many millions of Americans have connected to alternative news sources outside the continental United States. The information they consume can be and often is contrary to U.S. government statements and U.S. mainstream media reporting. Recognizing this, terrorists will coordinate their assaults with an adroit use of cyberspace for the purpose of manipulating perceptions, opinion, and the political and socioeconomic direction of many nation-states.
Analyzing Terror Campaigns on the Internet: Technical Sophistication, Content Richness, and Web Interactivity
2007 Qin, J., Zhou, Y., Reid, E., Lai, G. and Chen, H. Journal
Terrorists and extremists are increasingly utilizing Internet technology to enhance their ability to influence the outside world. Due to the lack of multi-lingual and multimedia terrorist/extremist collections and advanced analytical methodologies, our empirical understanding of their Internet usage is still very limited. To address this research gap, we explore an integrated approach for identifying and collecting terrorist/extremist Web contents. We also propose a Dark Web Attribute System (DWAS) to enable quantitative Dark Web content analysis from three perspectives: technical sophistication, content richness, and Web interactivity. Using the proposed methodology, we identified and examined the Internet usage of major Middle Eastern terrorist/extremist groups. More than 200,000 multimedia Web documents were collected from 86 Middle Eastern multi-lingual terrorist/extremist Web sites. In our comparison of terrorist/extremist Web sites to US government Web sites, we found that terrorists/extremist groups exhibited similar levels of Web knowledge as US government agencies. Moreover, terrorists/extremists had a strong emphasis on multimedia usage and their Web sites employed significantly more sophisticated multimedia technologies than government Web sites. We also found that the terrorists/extremist groups are as effective as the US government agencies in terms of supporting communications and interaction using Web technologies. Advanced Internet-based communication tools such as online forums and chat rooms are used much more frequently in terrorist/extremist Web sites than government Web sites. Based on our case study results, we believe that the DWAS is an effective tool to analyse the technical sophistication of terrorist/extremist groups' Internet usage and could contribute to an evidence-based understanding of the applications of Web technologies in the global terrorism phenomena.
Tweeting the Jihad: Social Media Networks of Western Foreign Fighters in Syria and Iraq
2014 Klausen, J. Journal
Social media have played an essential role in the jihadists’ operational strategy in Syria
and Iraq, and beyond. Twitter in particular has been used to drive communications over
other social media platforms. Twitter streams from the insurgency may give the illusion
of authenticity, as a spontaneous activity of a generation accustomed to using their
cell phones for self-publication, but to what extent is access and content controlled?
Over a period of three months, from January through March 2014, information was
collected from the Twitter accounts of 59 Western-origin fighters known to be in Syria.
Using a snowball method, the 59 starter accounts were used to collect data about the
most popular accounts in the network-at-large. Social network analysis on the data
collated about Twitter users in the Western Syria-based fighters points to the controlling
role played by feeder accounts belonging to terrorist organizations in the insurgency
zone, and by Europe-based organizational accounts associated with the banned British
organization, Al Muhajiroun, and in particular the London-based preacher, Anjem
Choudary.
Terrorist Financing and the Internet
2010 Jacobson, M. Journal
While al Qaeda has used the Internet primarily to spread its propaganda and to rally new recruits, the terrorist group has also relied on the Internet for financing-related purposes. Other Islamist terrorist groups, including Hamas, Lashkar e-Taiba, and Hizballah have also made extensive use of the Internet to raise and transfer needed funds to support their activities. The Internet's appeal in this regard for terrorist groups is readily apparent–offering a broad reach, timely efficiency, as well as a certain degree of anonymity and security for both donors and recipients. Unfortunately, while many governments now recognize that the Internet is an increasingly valuable tool for terrorist organizations, the response to this point has been inconsistent. For the U.S. and its allies to effectively counter this dangerous trend, they will have to prioritize their efforts in this area in the years to come.
Social Media, Recruitment, Allegiance and the Islamic State
2015 Gates, S. and Podder, S. Journal
Islamic State relies heavily on the recruitment of foreign fighters. We examine this recruitment from an
organizational perspective. We analyze how the process of recruitment of foreigners shapes the adverse selection
problem affecting the dissident groups that they join. We also examine the different mechanisms used to
maintain the allegiance and compliance of foreigners as opposed to indigenous recruits. More broadly, we
analyze how the recruitment of foreign fighters affects the organization. Foreign fighters and local recruits exhibit
significant differences in recruitment patterns and motivations for joining IS. This could create problems for the
organization. Evidence of such strife, however, is not discernible. Given the information at hand, IS appears to be
effectively managing the mix of foreign and local recruits.
Preliminary Analytical Considerations In Designing A Terrorism And Extremism Online Network Extractor
2014 Bouchard, M., Joffres, K. and Frank, R. Article
It is now widely understood that extremists use the Internet in attempts to accomplish many of their objectives. In this chapter we present a web-crawler called the Terrorism and Extremism Network Extractor (TENE), designed to gather information about extremist activities on the Internet. In particular, this chapter will focus on how TENE may help differentiate terrorist websites from anti-terrorist websites by analyzing the context around the use of predetermined keywords found within the text of the webpage. We illustrate our strategy through a content analysis of four types of web-sites. One is a popular white supremacist website, another is a jihadist website, the third one is a terrorism-related news website, and the last one is an official counterterrorist website. To explore differences between these websites, the presence of, and context around 33 keywords was examined on both websites. It was found that certain words appear more often on one type of website than the other, and this may potentially serve as a good method for differentiating between terrorist websites and ones that simply refer to terrorist activities. For example, words such as “terrorist,” “security,” “mission,” “intelligence,” and “report,” all appeared with much greater frequency on the counterterrorist website than the white supremacist or the jihadist websites. In addition, the white supremacist and the jihadist websites used words such as “destroy,” “kill,” and “attack” in a specific context: not to describe their activities or their members, but to portray themselves as victims. The future developments of TENE are discussed.
Islamic State Propaganda and the Mainstream Media
2016 Williams, L. Report
In this Lowy Institute Analysis, Lauren Williams examines Islamic State’s use of the Western media to disseminate its propaganda. Williams argues mainstream media outlets have a responsibility to treat Islamic State-produced material more critically, expose the weaknesses of its messages, and place greater effort into counter-messaging.

KEY FINDINGS
Islamic State’s media arm has a clearly defined strategy to manipulate the mainstream media to serve its propaganda objectives.
A more critical view of Islamic State’s claims and propaganda is needed to limit the effectiveness of the group’s messages.
The role of the media, as well as the stories of returnees and defectors, as a platform for counter-messaging has been underutilised.
Countering violent extremism through media and communication strategies - A Review of the Evidence
2016 Ferguson, K. Report
This report presents the analysis of a corpus of academic and grey literature relevant to a key
challenge facing our society. How can media and communications be used to counter identity-based
violence (IBV) or Violent Extremism (VE)?
Part I focuses on “Counter-Narratives”, looking at the evidence relating to strategic policy
communication strategies and counter-propaganda techniques. This reflects literature from
policymakers, think-tanks, and civil society initiatives rather than the academic literature base.
Key findings include the following:
• Current literature and policy concerned with countering propaganda is dominated by the language
of ‘counter-narratives’ but a common understanding of this relatively new lexicon has yet to emerge.
• There is little hard evidence that proves interaction with VE content leads to participation in VE
activities.
• The hypothesis that VE narratives or the real life threat of VE can be countered by an alternative set
of communications is an assumption that remains unproven.
These findings challenge claims that responding to propaganda strategies by firing back
with “counter-narratives” can be effective.
Part II looks at “Alternative Approaches” to the use of the media to counter violent extremism,
drawing on insights from the “media development” and “media assistance” sectors, and research
into whether mass media and new communication interventions can inhibit identity-based violence
in certain crisis situations. Key findings include the following:
• The theoretical foundations for these alternative approaches are supported by a stronger and more
established research base, drawn from the multi-disciplinary fields of development, peace building,
and social cohesion.
• Media projects have less impact if seen to be linked to a political agenda.
• A growing evidence base suggests that radio and television drama addressing issues of identity,
reconciliation and tolerance have a positive an impact on public attitudes and behaviour.
• Media assistance can ensure that local and domestic media can respond appropriately to VE
narratives.
• There is an emerging evidence base regarding the potential for rapid reaction media and
communication strategies in situations where there is a threat of IBV.
These findings suggest that alternative media strategies can help. But the trust and credibility of
information providers is crucial.
The final section “Reflections” concludes that the research landscape is fragmented and disconnected.
but suggests several professional/practitioner sectors and academic disciplines could shed light on
potentially effective media and communication CVE strategies.
More needs to be done to draw the threads together to learn lessons and to identify and prioritise
gaps in our knowledge and understanding.
Occasional Paper - The Islamic State’s Diminishing Returns on Twitter: How suspensions are limiting the social networks of English-speaking ISIS supporters
2016 Berger, J.M. and Perez, H. Report
Since late 2014, Islamic State of Iraq and Syria (ISIS) social networks on Twitter have been
subjected to periodic account suspensions. In a study of metrics for a network of English language
ISIS supporters active from June to October 2015, suspensions held the size and reach
of the overall network flat, while devastating the reach of specific users who have been
repeatedly targeted.
By analyzing a list of English-speaking ISIS adherents, we found:
• The number of readily discoverable English-speaking ISIS supporters on Twitter is
relatively small, usually fewer than 1,000 accounts.
• Extending the discovery process using advanced social network analysis produced a
network of fewer than 3,000 accounts at any given time.
• ISIS English-language social networks are extremely insular, meaning users mostly
follow and interact with each other.
• The number of users in the network who are based in Iraq and Syria appears to have
declined over time, partly because of suspension activity, but also because of operational
security concerns within ISIS and the deaths of some prominent Syria-based network
participants.
• The average number of Twitter followers any given ISIS supporter could expect was 300
to 400. Average follower counts were periodically reduced by aggressive waves of
suspensions. However, under typical conditions the average remained flat, as seen over a
30-day period beginning in late August, during which relatively few suspensions took
place.
• Over time, individual users who repeatedly created new accounts after being suspended
suffered devastating reductions in their follower counts.
• Network and individual declines persisted even when suspension pressure eased,
suggesting that suspensions diminish activity in ways that extend beyond the simple
removal of accounts.
• The amount of pro-ISIS content available on Twitter was also limited by suspensions,
since all of a user’s tweets are typically deleted when his or her account is suspended.
• ISIS supporters have deployed several countermeasures in an effort to offset the negative
effects of suspensions.
• Countermeasures include the use of applications and simple hacking techniques to
quickly create new accounts for users who have been suspended, as well as elaborate
tactics to rebuild follower networks. Some of these approaches are sophisticated, but they
have had only limited benefits.
• ISIS supporters have also explored the use of other social media platforms as a
supplement to Twitter, but they feel that a robust presence on Twitter and Facebook is
integral to their recruitment and propaganda efforts, and continue returning to those
platforms despite challenges.
Our analysis was based on a list of accounts maintained and promoted by ISIS supporters on
Twitter. The list was primarily billed as a resource for finding other ISIS supporters, but it
included some non-porter accounts, and the user who maintained the list did not follow all of
the listed accounts.
Tweeting Propaganda, Radicalization and Recruitment: Islamic State Supporters Multi-Sided Twitter Networks
2015 Chatfield, A., Reddick, C. and Brajawidagda, U. Article
Islamic State (IS) terrorist networks in Syria and Iraq pose threats to national security. IS' exploitation of social media and digital strategy plays a key role in its global dissemination of propaganda, radicalization, and recruitment. However, systematic research on Islamic terrorist communication via social media is limited. Our research investigates the question: How do IS members/supporters use Twitter for terrorism communication: propaganda, radicalization, and recruitment? Theoretically, we drew on microeconomic network theories to develop a theoretical framework for multi-sided Twitter networks in the global Islamic terrorist communication environment. Empirically, we collected 3,039 tweets posted by @shamiwitness who was identified in prior research as "an information disseminator" for the IS cause. Methodologically, we performed social network analysis, trend and content analyses of the tweet data. We find strong evidence for Shamiwitness-intermediated multi-sided Twitter networks of international mass media, regional Arabic mass media, IS fighters, and IS sympathizers, supporting the framework's utility.
How Do Terrorist Organizations Use Information Technologies- Understanding Cyber Terrorism
2016 Tombul, F. and Akdogan, H. Report
Globalization with advanced information technologies has changed the life of the people in
the world. When something occurs in one part of the world, other part of the world can be
informed easily within seconds. Current information technologies such as internet, social
media, blogs and news channels have enabled the people to create virtual groups all over the
world and to disseminate the information easily.
Most of the states, governments, public and private institutions have been using the advantage
of the information technologies to serve their citizens and customers. Concurrently, criminals
are also using the advantage of information technologies while committing crime. In other
words, everything including crime and criminals has changed their structures to be compatible
with the advanced information technologies.
Recently, lots of terrorist organizations have erupted especially in the Middle East and their
networks are spreading out with the use of technology. Most of the terrorist organizations
have been using the technology for military training of their militants, preparation, and
recruitment processes. Especially the internet is almost a virtual training slot for terrorist
groups. Recent studies (Weimann, 2006; Rothenberger, 2012) have revealed that the internet
is served as the library for the terrorist groups to provide instruction manuals and videos on
technical and tactical areas such as making a bomb, taking hostages, and guerilla combat. As
it has an appropriate space for interaction activities, potential terrorists use the advantage of
interaction face of the internet to learn how to make a bomb and send instant messages to the
instructors teaching illegal issues.
Thus, security forces in the face of all these developments should take the necessary
precautions to fight against the terrorist organizations by standing one step ahead on the use of
technology. Standing one step ahead can only be achieved understanding the phenomena and
ceaselessly updating the knowledge. Otherwise, security forces will fail if they maintain the
use of old technique and tactic to fight against the terrorist groups in this technology epoch.
Based on this point of view, this study will focus on understanding the use of technology to
fight against the terrorism. Furthermore, this study will also investigate some of the terrorist
organizations using the technology actively to commit crime. This study will also attempt to
shed light to the fact that different technologies have been used against the humanity by
terrorist groups although most of the people are not aware of that reality.
Check the Web - Assessing the Ethics and Politics of Policing the Internet for Extremist Material
2015 Brown, I. and Cowls, J. VOX-Pol Publication
This report assesses the ethics and politics of policing online extremist material, using the normative framework of international human rights law, particularly the International Covenant on Civil and Political Rights, European Convention on Human Rights and
the EU Charter of Fundamental Rights – whilst not conducting a legal analysis. It draws where appropriate upon interpretations by the UN Human Rights Committee, UN experts (such as the High Commissioner for Human Rights and special mandate holders), and regional human rights bodies and courts (such as the Council of Europe and the European Court of Human Rights). The report looks at definitions of ‘extremist material’; the types of monitoring and blocking being undertaken by government agencies and the private sector; and considers the roles of these key stakeholders, along with private individuals and civil society groups. It is based on a two-day workshop in January 2015 with thirty expert stakeholders from law enforcement and intelligence agencies, governments and parliaments, civil society, and universities. Short versions of ten papers were presented to stimulate discussion, following an open call for extended abstracts. These are available on the VOX-Pol website: https://www.voxpol.eu/.

The authors conducted seven follow-up semi-structured interviews with stakeholders from law enforcement, industry, government and civil society; and background policy analysis. The first author also co-organised a workshop on privacy and online policing with the UK’s National Crime Agency in March 2015, and participated in three further workshops where the topics of this report were addressed: two on law enforcement use of communications data, and a third at the United Nations on the relationship between encryption and freedom of expression. Both authors are grateful for the assistance of interviewees, co-organisers, and workshop participants.

The report is produced by the EU-funded VOX-Pol Network of Excellence, and takes particular account of the network’s development of semi-automated search for violent online extremist content and deployment of available tools for search and analytics, including text, video, sentiment, etc., currently employed in other domains for analysis of violent online extremist content. The network’s focus 6 CHECK THE WEB is on making these tools freely available for research purposes to academics, but may also extend to others professionally tasked in this area (such as activists and law enforcement agencies). It is also centrally concerned with the ethical aspects of deployment of such tools and technologies.
Implementation of Security Council resolution 2178 (2014) by States affected by foreign terrorist fighters
2015 UN Security Council Commitee Report
The present report is the second in a series of reports to be issued pursuant to
Security Council resolution 2178 (2014), which requires the Counter-Terrorism
Committee Executive Directorate to assess Member States’ capacity to stem the flow
of foreign terrorist fighters, identify good practices in that regard and facilitate the
delivery of related technical assistance to States in need. The first report adopted a
thematic approach to the foreign terrorist fighter threat, focusing on the
implementation efforts of 21 Member States. The second report adopts a regional
approach and analyses the efforts of 32 States in Central Asia, the Maghreb, East
Africa/Horn of Africa, Western Europe and Oceania/Americas.
