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.

The Rapper Bot network knocked out Elon Musk’s X social-media site earlier this year, cybersecurity researchers say.

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."
