Four DDoS botnets—Aisuru, KimWolf, JackSkid, and Mossad—collectively compromised over three million IoT devices (IP cameras, DVRs, WiFi routers) by exploiting default credentials, missing authentication, and insecure default initialization, culminating in a record 31.4 Tbps attack against DoD Information Network infrastructure. Law enforcement has seized C2 infrastructure, but device-level compromise persists on enrolled endpoints until firmware is patched or devices are factory-reset. Organizations should conduct an emergency IoT device inventory, force credential rotation, segment IoT devices onto isolated VLANs with egress filtering, and validate that DDoS mitigation SLAs cover current volumetric thresholds in light of the confirmed 31.4 Tbps peak.
