Microsoft and other software and services companies this week described their efforts in taking down the Trickbot criminal network.  The years-long effort involved working with the courts, software security firms and telcos to eliminate the hosting of Trickbot.  Microsoft’s software patents also came into play as a legal means to close it down.   “With this civil action, we have leveraged a new legal strategy that allows us to enforce copyright law to prevent Microsoft infrastructure, in this case our software code, from being used to commit crime,” in a Monday Microsoft announcement. “As copyright law is more common than computer crime law, this new approach helps us pursue bad actors in more jurisdictions around the world.”
