Imperva published a proof of concept (PoC) and the mitigations to be carried out for DDoS amplification attacks. The PoC shows attackers can use the UPnP devices to obfuscate the data from the source port of the amplification payloads and it is not limited with DNS amplification also with SDP, DNS, and NTP attacks. Business can estimate the cost and Probability of a DDoS attack with DDoS downtime cost calculator. The attack was a record-breaking attack, the Memcached amplification attack peaked up to 1.35Tbps via 126.9 million packets per second.”]
