From the Introduction: "As cyber criminals become more sophisticated in their efforts to target cyber victims, we must also grow our capabilities to successfully combat and defeat them. The evolving nature of Internet crime presents a unique set of challenges, as crimes often overlap jurisdictional boundaries and perpetrators can attack from anywhere on the globe. A crucial element to our mission of identifying, pursuing, and defeating cyber threats against our nation is the FBI's Internet Crime Complaint Center (IC3), which aids citizens by bringing pervasive cyber crimes and scams to the attention of law enforcement. The 2015 Internet Crime Report highlights the IC3's efforts over the past year, specifically focusing on their efforts regarding Business Email Compromise (BEC) and Email Account Compromise (EAC) scams and the Operation Wellspring Initiative (OWS)."
