According to journalist Ron Suskind, at the end of 2003, “The carefully constructed global network of [al-Qaeda’s] sigint and what can be called finint, or financial intelligence, started to go quiet. In short, al-Qaeda, and its affiliates and imitators, stopped leaving electronic footprints. It started slowly, but then became clear, a definable trend.” Al-Qaeda resorts more to low-tech methods, such as human couriers. One senior US intelligence official will later say, “We were surprised it took them so long” to figure out the dangers of electronic communication. [Suskind, 2006, pp. 277-279]
