Customizing AWS WAF Anti-DDoS AMR Responses for L7

🛡️This post explains how to customize AWS WAF Anti-DDoS AMR responses to Layer 7 DDoS events using labels and additional rules. It summarizes the AMR’s baseline‑and‑anomaly approach, default mitigations (a mix of Block and JavaScript Challenge), and the importance of excluding non‑challengeable paths. Three practical examples show geo‑based blocking, tightened rate limits, and adaptive capacity‑aware defenses, with JSON/IaC configuration guidance.

Aisuru Botnet Fires 15.72 Tbps DDoS at Microsoft Azure

⚠️ Microsoft reported that the Aisuru botnet launched a massive DDoS attack against a public Azure IP in Australia, peaking at 15.72 Tbps and nearly 3.64 billion packets per second. The traffic originated from over 500,000 IP addresses and consisted of extremely high-rate UDP floods with minimal source spoofing. Microsoft noted the bursts used random source ports, which aided traceback and provider enforcement. Azure's mitigations absorbed the attack without a reported widespread outage.
