Terrorism has changed over the past several decades, from the types of attacks they carry out to the way in which they finance these attacks. On the group level, terrorist organizations have used state sponsorship, diaspora support, charities, independent financiers, front organizations, selling their training and expertise to other groups, and have also used organized crime to finance themselves. At the cell level, carrying out operations does not cost nearly as much money. Petty crimes or even a full-time job can help cover the costs of carrying out a terrorist attack. By uncovering these networks that provide monetary and logistical support, terrorist networks can be disrupted.
