指挥控制过程中受干扰网络中攻击者行为分析

Analysis of Attacker Behavior in Compromised Hosts During Command and Control

Farhan Sadique, Shamik Sengupta

摘要:

将僵尸网络列入黑名单的传统反应式方法无法适应快速变化的网络攻击环境。自动化和主动的方法来检测和阻止僵尸网络主机将极大地有利于行业。僵尸网络的行为分析被证明是有效的,对各种各样的攻击类型。然而,目前的工作仅仅集中在分析来自和到达机器人的网络流量上。在这项工作中,我们采取不同的方法来分析攻击者在受损主机中输入的命令链。我们已经部署了几个蜜罐来模拟Linux shell,并允许攻击者访问shell以收集大量命令数据集。我们进一步开发了一种自动化机制来分析这些数据。为了实现自动化,我们开发了一个名为CYBEX-P(Cybersecurity information Exchange with Privacy)的系统。最后,我们对数据集进行了顺序分析,以表明我们可以成功地从shell命令预测攻击者行为,而无需像以前的工作那样分析网络流量。

英文摘要:

Traditional reactive approach of blacklisting botnets fails to adapt to the rapidly evolving landscape of cyberattacks. An automated and proactive approach to detect and block botnet hosts will immensely benefit the industry. Behavioral analysis of botnet is shown to be effective against a wide variety of attack types. Current works, however, focus solely on analyzing network traffic from and to the bots. In this work we take a different approach of analyzing the chain of commands input by attackers in a compromised host. We have deployed several honeypots to simulate Linux shells and allowed attackers access to the shells to collect a large dataset of commands. We have further developed an automated mechanism to analyze these data. For the automation we have developed a system called CYbersecurity information Exchange with Privacy (CYBEX-P). Finally, we have done a sequential analysis on the dataset to show that we can successfully predict attacker behavior from the shell commands without analyzing network traffic like previous works.
