Massive 11.5 Terabyte per second DDoS attack thwarted by Cloudflare, just two months following the previous record-breaking DDoS attack.
Cloudflare Mitigates Record-Breaking DDoS Attack
In a remarkable display of cybersecurity prowess, Cloudflare has successfully defended against a massive DDoS (Distributed Denial of Service) attack that took place on February 1, 2023. The attack, which originated from Google Cloud, was a UDP flood and peaked at an unprecedented 11.5 Tbps, making it the largest DDoS attack ever mitigated by Cloudflare.
The attack targeted a specific system, using spoofed IP addresses, and saw attackers sending large amounts of UDP traffic to random ports on the targeted system. This strategy aimed to quickly exhaust the system's resources by requiring the targeted server to check each incoming packet for a listening application and issue a response.
Prior to this attack, the previous record for Cloudflare was a DDoS attack of 7.3 Tbps, which occurred in June. Before that, the record was 3.8 Tbps and 2Bpps, an attack that Cloudflare also blocked in October 2024. The recent attacks are nearly 10 times the size of the 2021 record.
Despite the immense scale of these attacks, Cloudflare has managed to keep pace, thanks in part to its robust infrastructure. The company has been blocking multiple hyper-volumetric DDoS attacks over the past few weeks.
It is important to note that the intended target of the DDoS attack is unknown at this time. The search results do not provide specific information about which cloud service providers were involved in the 11.5 Tbps DDoS attack, beyond the fact that it originated from Google Cloud.
Cloudflare plans to reveal more information about these attacks in an upcoming report. The company's ability to mitigate such large-scale attacks underscores its commitment to maintaining the integrity and security of the internet.
As the internet continues to evolve, so too do the threats that it faces. These recent attacks serve as a reminder of the importance of robust cybersecurity measures and the role that companies like Cloudflare play in protecting the digital world.
