From the Jamestown Foundation: Technology and Security Discussions on the Jihadist Forums: Producing a More Savvy Next Generation
Jihadist groups operating online appear to be raising awareness about information and communications security, and stressing the importance of technical know-how in conducting successful operations. Two training manuals recently found on Internet discussion forums promoting militant Islam illustrate the importance of technical savvy to the jihadist movement. Formerly used chiefly as a platform for al-Qaeda statements and claims of responsibility for attacks by numerous groups, these forums have become a grassroots medium through which individuals without any particular group affiliation can post a document or manual of their own creation, subsequently useable as standard procedure for terrorist cells.
