A European DDoS mitigation service provider recently suffered a massive distributed denial-of-service attack reaching 1.5 billion packets per second (1.5 Gpps).
FastNetMon, a DDoS protection specialist, successfully defended against the assault that originated from compromised devices across more than 11,000 global networks.
DDoS attack mitigation techniques successfully defend against massive UDP flood assault
The attack used a UDP flood strategy leveraging a botnet of compromised customer-premises equipment (CPE), including Internet of Things devices and MikroTik routers. The malicious traffic’s widespread distribution across thousands of networks demonstrated the global scale of modern DDoS threats.
FastNetMon confirmed the victim was a DDoS scrubbing provider – companies that specialize in filtering malicious traffic through packet inspection, rate limiting, CAPTCHA implementation, and anomaly detection.
Real-time detection enables rapid response
FastNetMon detected the attack in real-time and immediately activated mitigation through the customer’s DDoS scrubbing infrastructure. The defense strategy included implementing access control lists (ACLs) on edge routers, particularly targeting those with known amplification capabilities.
This attack follows Cloudflare’s recent defense against a record-breaking 11.5 terabits per second volumetric DDoS attack that peaked at 5.1 billion packets per second, highlighting the escalating scale of these cyber threats.
How to protect your network from large-scale DDoS attacks
Organizations can implement several protective measures against DDoS attacks:
- Deploy real-time DDoS monitoring tools like FastNetMon for immediate threat detection
- Configure access control lists (ACLs) on edge routers to block suspicious traffic patterns
- Implement rate limiting to control incoming packet volumes
- Use CAPTCHA systems to distinguish legitimate users from automated attacks
- Enable anomaly detection systems to identify unusual traffic behaviors
- Partner with DDoS scrubbing service providers for additional protection layers
ISP-level intervention needed to stop botnet weaponization
Pavel Odintsov, FastNetMon’s founder, emphasized the growing danger of large-scale attacks and called for internet service provider intervention to prevent compromised consumer hardware weaponization.
“What makes this case remarkable is the sheer number of distributed sources and the abuse of everyday networking devices. Without proactive ISP-level filtering, compromised consumer hardware can be weaponised at a massive scale.”
“The industry must act to implement detection logic at the ISP level to stop outgoing attacks before they scale.”
The attack’s primary objective was to overwhelm the targeted system’s processing capacity to cause service disruptions, demonstrating why proactive defense measures remain critical for maintaining network security and availability.
