The world’s most dangerous jihadists no longer answer to al Qaeda. The terrorists we should fear most are self-recruited wannabes who find purpose in terror and comrades on the Web. This new generation is even more frightening and unpredictable than its predecessors, but its evolution just may reveal the key to its demise.

Security informatics and intelligence computation plays a vital role in detecting and classifying terrorism contents in the web. Accurate web content classification using the computational intelligence and security informatics will increase the opportunities of the early detection of the potential terrorist activities. In this paper, we propose a modified frequency-based term weighting scheme for accurate Dark Web content classification. The proposed term weighting scheme is compared to the common techniques used in text classification such as Term Frequency (TF), Term Frequency-Inverse Document Frequency (TF-IFD), and Term Frequency- Relative Frequency (tf.rf), on a dataset selected from Dark Web Portal Forum. The experimental results show that the classification accuracy and other evaluation measures based on the proposed scheme outperforms other term weighting techniques based classification.

This study investigated the phenomena of group polarisation with particular attention to the differences between offline and online settings. Polarisation is a process that leads people to develop extreme ideologies. Three hundred and seven participants were recruited and randomly assigned to different experimental conditions, i.e. antisocial and prosocial polarisation, within groups of 6 people composed of four confederates, participating in discussions about a social dilemma under two different circumstances: face to face and online. The degree of polarisation was assessed considering the final decisions adopted by the participants, as well as the internal dynamics characterising their final attitudes, i.e. compliance versus conversion. Results showed that online groups appeared more susceptible to polarisation and their members reported a greater degree of conformism. In particular, within online environments, the risk of being polarised, both antisocially and prosocially, increased by around 12%. Furthermore, in an online setting, a greater degree of conversion emerged only when the members decided to adopt a pro-social behaviour, while a greater degree of compliance emerged whenever they decided to adopt antisocial behaviour.

A strategy to counter violent radicalisation on the Internet must be user driven, empowering Internet users with “cultural intelligence”. Cultural intelligence is essentially shorthand for an understanding of the key pillars of, and vulnerabilities inherent in, militant Islamist rhetoric. What this report calls “Enabling Stakeholders”, such as schools, and religious and community organisations, can disseminate this knowledge, thereby empowering Internet users to choose whether and how to challenge the call to violence.
