it Has been driven by the capabilities of large Memcached, according to Akamai, which believes “likely that the attackers will adopt quickly, this method”.

The attack is linked to the botnet Mirai caught the headlines in 2016 because of their size. But it has been surpassed.

The month of February 2018 has finished with a DDoS attack that has been described by Akamai Technologies as the “largest seen to date”. With 1.3 Tbps has more than doubled the size of that case Mirai.

This has been made possible by the use of Memcached. “The February 27, Akamai and other companies announced the discovery of a vector for the reflection and amplification of Memcached recently observed,”, explains the first of these company. “This service is intended to store in a cache the data and reduce the stress caused by the services memory-intensive. Memcached can have listeners UDP and TCP and it does not require authentication”, he says. “As UDP is easily falsifiable (spoofable), makes this service vulnerable to use as a reflector. Even worse”, hits Akamai, “you can have an amplification factor of more than 50,000, which means that an application of 203 bytes results in a response of 100 megabytes”.

So, taking into account the capabilities of large Memcached, it seems that the attack could end up “overcome in a short time,”.

Akamai predicts that “due to their ability to create such massive attacks, it is likely that the attackers will adopt quickly this method” and to use “as their favorite tool”.
