**Executive summary:** The Aisuru botnet — a rentable network of compromised routers and IoT devices estimated at 1–4 million hosts — carried out more than 1,300 DDoS attacks in three months, including a record 29.7 Tbps UDP carpet-bombing strike that Cloudflare mitigated; hyper‑volumetric attacks are rising and can disrupt ISPs and critical infrastructure.
