Internet infrastructure providers mitigated the largest distributed denial-of-service attack ever recorded, peaking at 9.4 terabits per second against a financial services platform.
The hyper-volumetric assault lasted under two minutes but originated from hundreds of thousands of compromised IoT devices, routers and cloud virtual machines spanning 130 countries.
Analysts linked the botnet to a Mirai-descended malware family that has aggressively absorbed poorly secured connected devices, from cameras to smart appliances.
While the attack was absorbed without customer-facing outages, researchers warn that record-setting attack volumes now recur every few months, straining smaller providers that lack hyperscale mitigation capacity.
