It describes who acted when where and why then details AttackIQ emulation updates used to measure detection and prevention against a globally distributed espionage campaign affecting government technology and telecommunications environments.

Introduction

Cloudflare mitigated an unprecedented volumetric DDoS event that peaked at 11.5 terabits per second and reached roughly 5.1 billion packets per second. This short, intense UDP flood lasted about 35 seconds and highlighted evolving threat-intelligence patterns tied to botnet recruitment of IoT, NVR and DVR edge devices, as well as involvement from multiple cloud providers including Google Cloud. The incident underscores the growing scale of volumetric-attacks, the operational role of botnet toolkits such as RapperBot, and the importance of automated mitigation and cross-provider coordination in modern network defense.
