281 people were arrested over a four-month period in the U.S. and in countries around the world as part of Operation reWired, a coordinated effort to disrupt Business Email Compromise (BEC) schemes that are designed to intercept and hijack wire transfers from businesses and individuals, including many senior citizens. The operation also led to the seizure of approximately $3.7 million which were collected by BEC scammers. BEC victims have lost over $1,2 billion during 2018 according to an Internet Crime report published on April 2019.
