Attackers Using Memcached Servers to Amplify DDoS Attacks

Akamai reported that it has seen multiple sets of memcached reflection attacks, with some that were approximately 190 Gbps of attack traffic. Arbor Networks reported that it is seeing memcached attacks that are even larger.

There are several things that can be done to help mitigate the risk of memcached reflection attacks. The most obvious thing that should be done is for organizations to not expose their memcached services to the public internet.
