Memcached UDP Reflection Attacks

Akamai is aware of a new DDoS reflection attack vector: UDP-based memcached traffic. Memcached is a tool meant to cache data and reduce strain on heavier data stores, like disk or databases. The protocol allows the server to be queried for information about key value stores and is only intended to be used on systems that are not exposed to the Internet. There is no authentication required with memcached. When

A Death Match of Domain Generation Algorithms

By Hongliang Liu and Yuriy Yuzifovich Originally posted on December 29, 2017 Today's post is all about DGA's (Domain Generation Algorithms): what they are, why they came into existence, what are some use cases where they are used, and, most importantly - how to detect and block them. As we will demonstrate here, the most effective defense against DGAs is a combination of traditional methods with modern machine intelligence.
