"ISIL has a large cadre of Western fighters who could potentially serve as operatives for attacks in the West," CIA Director John Brennan told the Senate intelligence committee on Thursday. One way ISIS has developed its global network is through social media, where the group has shown a great deal of savvy manipulating it to its purpose. A software tool, unveiled on Friday, hopes to combat Islamic State’s online threat. The Counter Extremism Project, a Washington-based NGO, has proposed a software tool, developed by Hany Farid of Dartmouth University, to quickly find and delete online content used to spread messages of violence and extremist ideology.
