A record-scale distributed denial-of-service (DDoS) attack targeted the website of a leading DDoS scrubbing vendor in Western Europe, reaching 1.5 billion packets per second (1.5 Gpps)—one of the largest packet-rate floods ever disclosed. The attack was a UDP flood launched from over 11,000 compromised networks worldwide, including hijacked IoT devices and customer-premises equipment (CPE). While FastNetMon’s advanced detection platform mitigated the attack within seconds, preventing service disruption, the incident highlights escalating risks for network operators.The attack follows a recent 11.5 Tbps DDoS assault reported by Cloudflare, signaling a dangerous trend where attackers exploit vulnerable CPE devices for unprecedented-scale packet and bandwidth floods. Though no data breach or financial loss was reported, the attack strained infrastructure defenses and demonstrated the potential for future outages or cascading disruptions if such floods overwhelm mitigation systems. The vendor’s rapid response averted immediate harm, but the event underscores systemic vulnerabilities in global network security, particularly from botnet-driven volumetric attacks leveraging unsecured IoT ecosystems.
