Security News > 2024 > October > Cloudflare Thwarts Largest-Ever 3.8 Tbps DDoS Attack Targeting Global Sectors

Cloudflare has revealed that it successfully mitigated a record-breaking distributed denial-of-service (DDoS) attack that peaked at 3.8 terabits per second (Tbps) and lasted 65 seconds. This attack was part of a larger wave of over one hundred hyper-volumetric Layer 3/4 DDoS attacks throughout the month. Many of these attacks exceeded 2 billion packets per second (Bpps) and 3 Tbps, showcasing the increasing scale and intensity of such threats. The attacks, which have been ongoing since early September 2024, primarily targeted customers in the financial services, Internet, and telecommunications industries.

Cloudflare has not attributed these attacks to any specific threat actor. However, the scale of the attacks underlines the growing sophistication of cybercriminals, who continue to exploit vulnerabilities in global digital infrastructure. The company emphasized that these hyper-volumetric attacks focus on overwhelming network layers responsible for packet transmission and reception (L3/4).

This recent attack surpasses the previous record set in November 2021, when a DDoS attack on an unnamed Microsoft Azure customer in Asia reached 3.47 Tbps. DDoS attacks are known to disrupt services by overwhelming targeted systems with massive volumes of traffic, rendering them inoperable.

Cloudflare’s ability to defend against such a large-scale attack highlights the importance of robust web infrastructure and security solutions, especially for industries like finance and telecommunications, which are frequently targeted by such assaults. The continued rise of these threats underscores the need for proactive and resilient cybersecurity measures.
