Kimwolf botnet disrupts I2P, an anonymity network, by overwhelming it with infected devices. Emerged in late 2025, it turns IoT devices into relays for DDoS attacks. Users reported connectivity issues as Kimwolf attempted to escape detection by taking over I2P nodes. This “Sybil attack” compromised the network's integrity, reducing its capacity. Experts believe Kimwolf's operators are experimenting with I2P for stability amid takedown attempts, though botnet numbers are declining due to internal issues and errors.
