Memcached has a whopping amplification factor of up to 51,000, which means: Put these two together, and the attack no longer looks so challenging: since the PPS volume is relatively low, a mitigation appliance could be used. Once we have passed the network capacity barrier, there is still a ton of traffic to be processed. In other words, a packet of N bytes will be bounced to the attacked server as a packet of size N times the “amplification factor.”. Packets per second is the true measure of the attack intensity, and that is what is difficult to block and recover from. “For example, in Imperva’s 2019 Global DDoS Threat Landscape Report, we found that about 29% of attacks lasted 1-6 hours while 26% lasted less than 10 minutes. ...

Volumetric DDoS attacks are designed to disrupt normal traffic by overwhelming the target of the attack with a flood of traffic from multiple sources. 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. Alternatively, it could be a perfect candidate for traffic filtering (i.e. Network appliances mostly evaluate the headers of the packets (every packet!) That’s more than four times the volume of packets sent at GitHub last year and we believe at the time was the largest PPS attack publicly disclosed (see bottom of post to learn about a recent even larger attack we recorded).
