FastNetMon, a leading provider of network security solutions, reports that record-breaking distributed denial-of-service (DDoS) attacks in 2025 are powered by Aisuru, a rapidly evolving global botnet. Leveraging an army of compromised devices — from routers to cameras — Aisuru has executed some of the largest attacks ever recorded, creating new challenges for internet stability.
“Hyper-scale attacks like those powered by Aisuru aren’t just isolated incidents anymore. They’re a warning that the internet’s resilience is being tested on a daily basis, and it affects every service we rely on — from email and entertainment to finance and healthcare,” said Pavel Odintsov, founder of FastNetMon.
Unlike earlier attacks, which were slow and small, these assaults are fast, intense, and enormous in scale. One recent incident generated enough traffic to stream tens of millions of high-definition movies at once, illustrating the extraordinary strain super-botnets can place on networks worldwide.
DDoS Attacks Are Growing Exponentially
DDoS attacks have evolved dramatically over the past two decades. Early attacks in the 2000s, measured in megabits or gigabits per second, could disrupt a single website temporarily. By 2015–2020, terabit-level floodsappeared, challenging even the largest providers.
Now, multi-terabit assaults are becoming frequent. FastNetMon’s data shows that attack volumes are rising faster than many defenses can adapt, creating persistent risks for everyday internet users and businesses alike.
The Hidden Ripple Effect
Attacks orchestrated by super-botnets like Aisuru originate from a large pool of compromised devices, creating massive traffic surges that ripple across the internet. This is especially critical in regions like Latin America, where international network capacity is limited. When a multi-terabit attack crosses overseas links, it can slow services for everyone — not just the intended target —affecting streaming, banking, and business operations.
“The internet is a shared ecosystem. Protecting it isn’t just a technical challenge — it’s essential to ensuring that the services people depend on every day remain reliable,” added Odintsov.
Rapid detection and mitigation solutions, such as FastNetMon, are now critical for networks to detect attacks in real time and prevent disruptions from spilling across networks. Protecting digital operations now requires global visibility, rapid response, and collaboration across providers and regions, ensuring that the internet remains collectively resilient even in the face of record-breaking attacks.
