**Executive summary:** The Kimwolf IoT botnet, which has infected large numbers of poorly secured IoT devices, attempted to join I2P en masse and effectively executed a Sybil-style disruption that overwhelmed the anonymity network; operators are also experimenting with I2P and Tor as fallback command-and-control channels while continuing large-scale DDoS and DNS-manipulation activity.
