From what I understand the attack originates from publicly exposed memcached servers configured to support udp and that have no authentication requirements:
- put a large object in a key
- construct a memcached "get" request for that key
- forge the IP address of the udp request to point to that of the target/victim server
- memcached sends the large object to the target/victim
Multiply times thousands of exposed memcached servers.
That about right?
