memcached reflection attack

2018-03-01 19:24:12.062427+00 by Dan Lyke 0 comments

Holy shit: Akamai: memcached-fueled 1.3 TBPS attacks.

On February 27th, Akamai and other companies announced the discovery of a newly observed reflection and amplification vector, memcached. This service is meant to cache data and reduce the strain caused by memory intensive services. Memcached can have both UDP and TCP listeners and requires no authentication. Since UDP is easily spoofable, it makes this service vulnerable to use as a reflector. Worse, memcached can have an amplification factor of over 50,000, meaning a 203 byte request results in a 100 megabyte response.
