2. GRE attack

https://krebsonsecurity.com/2016/09/krebsonsecurity-hit-with-record-ddos/

Krebsによれば、今回の攻撃はDNSを利用するものではなかったと。 

generic routing encapsulation (GRE) data packets,
a communication protocol used to establish a direct, point-to-point connection
between network nodes.

GRE lets two peers share data they wouldn’t be able to share over the public network itself.

McKeay explained that the source of GRE traffic can’t be spoofed or faked the same way DDoS attackers can spoof DNS traffic.

Nor can junk Web-based DDoS attacks like those mentioned above. That suggests the attackers behind this record assault launched it from quite a large collection of hacked systems — possibly hundreds of thousands of systems.
