  • Previous homeland-based plots have included, among other things, scouting and planning against infrastructure targets and cyber enabled attacks against a range of U.S. based targets.
  • Iran maintains a robust cyber program and can execute cyber attacks agains the United States.  Iran is capable, at a minimum, of carrying out attacks with temporary disruptive effects against critical infrastructure in the United States.
  • Iran likely views terrorists activities as an option to deter or retaliate against its perceived adversaries.  In many instances, Iran has targeted United States interests through its partners such as Hizballah.
