Brinztech Alert: DDoS Mitigation Service Targeted in Massive 1.5 Bpps Attack

Cyberattack Analysis

A European Distributed Denial-of-Service (DDoS) mitigation service provider was recently targeted in a massive attack that peaked at an astonishing 1.5 billion packets per second (Bpps), making it one of the largest packet-rate floods ever publicly disclosed. The attack, which was successfully mitigated by the cybersecurity company FastNetMon, originated from a large, globally distributed botnet. The malicious traffic was a UDP flood launched from thousands of compromised customer-premises equipment (CPE), including IoT devices and routers, spread across more than 11,000 unique networks worldwide.  

This incident, coming just days after Cloudflare announced it had blocked a record-breaking 5.1 Bpps attack, demonstrates a clear and dangerous trend of escalating DDoS attack volumes. These attacks are designed to exhaust the processing capabilities of the target’s servers and network infrastructure, causing complete service outages.  

Key Insights

This major cyberattack provides several critical insights into the modern threat landscape:

• The Escalating Scale of DDoS Attacks: Modern DDoS attacks are reaching unprecedented volumes. The goal is to generate a flood of traffic so massive that it can overwhelm even the specialized defenses of a DDoS mitigation provider. This trend signifies a dangerous arms race between attackers and defenders.
• Weaponization of Consumer and IoT Devices: The attack was sourced from a botnet of thousands of compromised everyday networking devices. This highlights how attackers are continuing to build massive, globally distributed botnets by exploiting insecure consumer hardware, such as routers and IoT gadgets, which are often poorly secured by their owners.  
• A Direct Attack on a Defender: It is highly significant that the target was a DDoS “scrubbing provider”—a company whose entire business is to defend other organizations from these attacks. This represents a bold move by the attackers, designed to test the limits of modern defenses and make a statement within the cybercrime community.

Strategic Recommendations

The growing scale of these attacks requires a multi-layered, collaborative defense strategy:

• Proactive ISP-Level Filtering is Required: As noted by FastNetMon’s founder, the ultimate solution to the botnet problem is for Internet Service Providers (ISPs) to implement outbound filtering. By detecting and blocking attack traffic as it leaves their own networks, ISPs can stop these massive attacks before they can be fully weaponized.
• All Organizations Need a Professional DDoS Mitigation Plan: Given that modern attacks can easily exceed the capacity of traditional on-premises firewalls, all businesses with a critical online presence must subscribe to a professional, cloud-based DDoS scrubbing service that has the global capacity to absorb and filter these massive traffic floods.
• Secure the IoT and Home Network Ecosystem: The root cause of these powerful botnets is the proliferation of insecure consumer hardware. This serves as a call to action for manufacturers to build more secure-by-default devices and for consumers to properly secure their home routers and IoT gadgets by changing default passwords and applying security updates.
