Please make sure your memcached servers are secured

Hi, If you are running a memcached server please make sure that it either doesn't listen on UDP or else that it is properly firewalled. Publicly available memcached servers can provide a 50,000x traffic amplification: <https://blog.cloudflare.com/memcrashed-major-amplification-attacks-from-port-11211/> As there is no authentication in the memcached protocol, having it publicly available is generally a misconfiguration anyway. We will start scanning for and nagging about this soon. Cheers, Andy -- https://bitfolk.com/ -- No-nonsense VPS hosting
