Overview
- On October 24, 2025, Azure DDoS Protection automatically detected and mitigated a multi‑vector flood peaking at 15.72 Tbps and nearly 3.64 billion packets per second against a single endpoint in Australia.
- Microsoft reports no customer workloads were interrupted as malicious traffic was filtered and redirected across its global protection network.
- The assault relied on largely non‑spoofed UDP traffic with randomized source ports from over 500,000 IP addresses, which eased traceback and provider enforcement.
- Aisuru is a Turbo Mirai–class IoT botnet built from compromised home routers and cameras on residential ISP networks, and security firms have linked it to repeated record‑scale campaigns.
- Researchers also tied Aisuru to Cloudflare’s 22.2 Tbps event in September and to recent 20+ Tbps barrages against gaming and broadband targets, prompting renewed guidance to verify DDoS protections heading into the holiday period.
