Authorities charged Ethan Foltz, 22, with one count of aiding and abetting computer intrusions. Police executed a search warrant at Foltz’s house on Aug. 6, shut down the botnet and took control of its infrastructure, according to the U.S. Department of Justice.

The control panel for the Rapper Bot botnet greets users with the message “Welcome to the Ball Pit, Now with refrigerator support,” an apparent reference to a handful of IoT-enabled refrigerators that were enslaved in their DDoS botnet.

Prosecutors said the network created by 22-year-old Ethan Foltz is "one of the most sophisticated and powerful DDoS-for-hire Botnets currently in existence."
