Over the past few days researchers say DDoS attacks have been using memcached servers to amplify DDoS attacks using UDP-based packets.
Cybercriminals behind distributed denial of service attacks have added a new and highly effective technique to their arsenal to amplify attacks by as much as 51,200x by using misconfigured memcached servers accessible via the public internet.
The technique was reported by Akamai, Arbor Networks and Cloudflare on Tuesday. All said they have observed an uptick in DDoS attacks using User Datagram Protocol (UDP) packets amplified by memcached servers over the past two days. Memcached servers are a type of server used to bolster responsiveness of database-driven websites by improving the memory caching system.
