1.5 Gpps DDoS Attack Hits Mitigation Provider – 1.5 Billion Packets per Second Flood

Executive Summary

A DDoS mitigation provider in Western Europe has confirmed being hit with one of the largest packet-rate DDoS floods ever recorded: approximately 1.5 billion packets per second (1.5 Gpps). Unlike pure volumetric bandwidth floods, this packet-rate attack targeted the processing limits of routers, switches, and firewalls.

The attack was:

Launched using a botnet of thousands of compromised IoT devices and routers, including MikroTik hardware.
Distributed across 11,000+ unique networks worldwide.
Detected and mitigated by FastNetMon, a DDoS detection and scrubbing platform.
Designed to overwhelm the packet-handling capacity of the provider’s infrastructure.

This attack demonstrates that DDoS providers themselves are targets, and taking them offline could disrupt protection for thousands of downstream clients.

Background on DDoS & Packet Floods

Traditional DDoS attacks are categorized as:

Volumetric (bps/Gbps) – overwhelm bandwidth capacity.
Application Layer (HTTP floods, Slowloris) – target application endpoints.
Packet-Rate Attacks (pps/Gpps) – flood devices with enormous packets per second to overwhelm processing tables and CPU.

The 1.5 Gpps attack belongs to the third category, targeting the packet handling capacity of network equipment rather than just bandwidth.

Technical Breakdown of the 1.5 Gpps Attack

Attack Vector

UDP Floods with massive packet rate.
Exploited poorly secured IoT devices, routers, and edge appliances.
Botnet scale: >11,000 networks globally.

Why Packet-Rate Matters

Routers and firewalls can handle certain bandwidth levels, but packet-per-second processing is finite.
Even with moderate bandwidth, billions of packets can saturate CPU and cause device lock-ups or crashes.
Attackers bypass “traditional volumetric” defenses by overloading control-plane processing instead of raw bandwidth.

Defensive Response

FastNetMon detected anomalies in real time.
Scrubbing centers filtered malicious traffic.
Access Control Lists (ACLs) applied on vulnerable edge routers.
Upstream ISPs cooperated to block abusive traffic.

Attack Motives & Threat Landscape

Why would attackers hit a DDoS mitigation provider?

Reputation Damage: Showing that even security providers can be crippled undermines trust.
Collateral Impact: If a provider is offline, all downstream clients become exposed.
Proof-of-Concept: Botnet owners may showcase power to sell DDoS-as-a-Service.
Disruption: Targeted disruption of financial, media, or government services protected by the mitigation vendor.

Business Impact

Impact Area	Potential Damage
Mitigation Provider	Service outages, infrastructure stress, reputational loss.
Downstream Clients	Downtime, loss of protection, exposure to secondary attacks.
Internet Service Providers (ISPs)	Router CPU exhaustion, collateral congestion.
End Users	Loss of service availability for websites, apps, and APIs.

Defensive Lessons Learned

For Mitigation Providers

Overprovision capacity for packet handling (pps, not just bps).
Deploy FastNetMon-style low-latency detection with automated scrubbing.
Build multi-layer defenses: edge filtering, ISP cooperation, scrubbing centers.

For Enterprises Relying on Mitigation

Multi-provider strategy: Don’t rely on a single vendor.
Rate-limit inbound UDP traffic at ISP and enterprise level.
Zero Trust architecture: minimize attack surface by segmenting services.
Cloud scrubbing add-ons: AWS Shield Advanced, Cloudflare Magic Transit, Akamai Kona Site Defender.

CyberDudeBivash Recommendations

Conduct DDoS tabletop exercises to test resilience.
Monitor for IoT botnet growth that can be weaponized.
Encourage ISPs to deploy BCP-38 anti-spoofing to reduce reflection floods.
Adopt hybrid mitigation models: on-prem + cloud scrubbing.

Conclusion

This 1.5 Gpps DDoS attack highlights a dangerous evolution in cyber warfare. By targeting a mitigation provider itself, attackers prove that even the defenders can be overwhelmed.

Organizations must:

Prepare for packet-rate floods.
Adopt multi-layered DDoS defenses.
Build resilient network architectures.
Leverage Zero Trust and redundancy to survive massive disruptions.
