Anti-DDoS outfit walloped by record packet flood www.theregister.com/2025/09/1…

A DDoS mitigation provider was given a taste of the poison it tries to prevent, after being smacked by one of the largest packet-rate attacks ever recorded – a 1.5 billion packets per second (1.5 Gpps) flood that briefly threatened to knock it off the internet.

FastNetMon, the network monitoring outfit brought in to fight the attack, said the UDP flood was launched from thousands of compromised routers and IoT devices spread across more than 11,000 networks worldwide.

The attack targeted a DDoS scrubbing vendor in Western Europe whose job is to keep other people’s services online during incidents just like this. FastNetMon spokesperson Outi Maria Pietilänaho declined to name the targeted vendor, however, she told The Register that FastNetMon had observed another incident of almost exactly the same scale (1.49 Gpps), targeting another DDoS scrubbing provider in Eastern Europe, She said this “strongly suggests activity from the same botnet.”
