Last week, an international group of law enforcement agencies took down one of the biggest criminal operators of a spoofing-as-a-service enterprise. Called iSpoof, it collected more than $120M from victims across Europe, Australia, Ukraine, Canada, and the United States. During the 16 months of the site’s operation, the group took in more than $3.8M in fees from its victims. In my blog for Avast, I summarize what happened, why this gang was so significant, and how spoofing has gotten more advanced over the years since those early days when Paris Hilton spoofed her friend’s cellphone.
