DGA-Detection
DGA-Detection 越来越多的恶意软件采用了先进的规避阻断技术。其中一种最为普遍的技术是使用域生成算法(Domain Generation Algorithms),该算法周期性地生成一组域名用于联系命令与控制服务器(C&C server)。这些 DGA 域名大多生成随机的字母数字字符串,与标准域名的结构显著不同。通过观察某个域名中一组二元组(bigrams)在 Alexa 前 100 万域名中出现的频率,我们能够判断该域名是由随机字符串构成,还是合法的、可读的域名。如果一个域名几乎完全由低频二元组构成(这些二元组在 Alexa 前 100...

DGA-Detection - DGA Domain Detection using Bigram Frequency Analysis
More and more malware is being created with advanced blocking circumvention techniques. One of the most prevalent techniques being used is the use of Domain Generation Algorithms which periodically generates a set of Domains to contact a C&C server. The majority of these DGA domains generate rand...
