Title: Microsoft Mitigated the Largest Cloud DDoS Ever Recorded, 15.7 Tbps

An anonymous reader quotes a report from Security Affairs: On October 24,
2025, Azure DDoS Protection detected and mitigated a massive multi-vector
attack peaking at 15.72 Tbps and 3.64 billion pps, the largest cloud DDoS
ever recorded, aimed at a single Australian endpoint. Azure's global
protection network filtered the traffic, keeping services online. The attack
came from the Aisuru botnet, a Turbo Mirai-class IoT botnet using compromised
home routers and cameras. The attack used massive UDP floods from more than
500,000 IPs hitting a single public address, with little spoofing and random
source ports that made traceback easier. It highlights how attackers are
scaling with the internet: faster home fiber and increasingly powerful IoT
devices keep pushing DDoS attack sizes higher. "On October 24, 2025, Azure
DDOS Protection automatically detected and mitigated a multi-vector DDoS
attack measuring 15.72 Tbps and nearly 3.64 billion packets per second (pps).
This was the largest DDoS attack ever observed in the cloud and it targeted a
single endpoint in Australia," reads a report published by Microsoft. "The
attack originated from Aisuru botnet." "Attackers are scaling with the
internet itself. As fiber-to-the-home speeds rise and IoT devices get more
powerful, the baseline for attack size keeps climbing," concludes the post.
"As we approach the upcoming holiday season, it is essential to confirm that
all internet-facing applications and workloads are adequately protected
against DDOS attacks."
