Arbor Networks, CloudFare, Data Center, DDoS Misconfigured memcached servers on internet data center (IDC) networks are being increasingly abused to conduct amplification attacks around the globe, with many vulnerable servers across Asia Pacific, Europe and North America.
Arbor Networks defines memcached as an in-memory database caching system often deployed in IDC, cloud and Infrastructure-as-a-Service networks to improve performance of database-driven websites and other internet services.
Ideally memcached should not be exposed to public internet but there are many deployments that leave the systems open and with the default insecure configuration.
Those attacks are getting bigger, according to Arbor Networks, which says there has been in increased in memcached attacks, some reaching as much as 500gb/sec and larger.
Cloudflare is also calling on internet service providers to help track attackers by finding out where the queries came from.
