Dysphoria IoT Botnet Evolves with Blockchain C2 After JackSkid Takedown

The Dysphoria IoT botnet has adopted blockchain-based command-and-control and infected-device relays following a March law enforcement operation against JackSkid infrastructure. Researchers from CNCERT and XLab report the changes make the botnet significantly harder to disrupt. The botnet targets IoT devices, leveraging their numbers for distributed attacks.
