Esta técnica de mitigación depende de que la víctima atacada envíe un comando "flush_all" a los servidores atacantes. La medida fue propuesta la semana pasada por Dormando, uno de los desarrolladores de servidores de Memcached.
"For what it's worth, if you're getting attacked by memcached's, it's pretty easy to disable them since the source won't be spoofed. They may accept "shutdown\r\n", but also running "flush_all\r\n" in a loop will prevent amplification. "
