Largest DDoS Attack Sent Over 500 Million Packets per Second

January 30, 2019 / Kacy Zurkus

A distributed denial-of-service (DDoS) attack discovered by Imperva had unleashed more than 500 million packets per second (Mpps), which is believed to be the largest packets-per-second (PPS) attack on record. According to research released today, last year’s DDoS attack on GitHub rang in at 1.35 terabits per second, making it the largest DDoS attack ever at the time. According to Imperva, though, the ability to mitigate a DDoS attack has more to do with the number of packets directed at a network than it does with the amount of bandwidth. “Packets per second is the true measure of the attack intensity, and that is what is difficult to block and recover from,” researchers wrote. “When it comes to DDoS protection, bandwidth is not everything. The most demanding attacks are high-volume PPS attacks, because with more packets to process, you need more network hardware and other resources to mitigate them.”
