Memcrashed - Major amplification attacks from UDP port 11211

A new amplification attack vector using the memcached protocol has been discovered, causing a significant increase in DDoS attacks. The memcached UDP DDoS is capable of generating massive bandwidth due to its large response packets. Memcached servers are found worldwide, with higher concentrations in North America and Europe. To prevent further attacks, users should disable UDP support if not needed, system administrators should firewall memcached servers from the internet, and developers should avoid using UDP or enable it by default.
