The study, by researchers from the University of Cambridge and University of Strathclyde, looked at four different types of law enforcement interventions, the first evaluation of the their effectiveness for this particular type of cybercrime.

They found that while high-profile arrests and sentencing of cybercriminals only lead to a short drop in the number of attacks taking place, the takedown of infrastructure and targeted messaging campaigns were strongly associated with a sharper and longer-term reduction in attack numbers. The results will be presented today (21 October) at the ACM Internet Measurement Conference in Amsterdam.
