攻击者依赖大量工具来自动化攻击易受攻击的服务器和服务。通常情况下,当漏洞被披露时,用于在NmapandMetasploit等工具中检测和利用它们的脚本很快就会发布,从而导致立即识别和危害易受攻击的系统。蜜罐、蜜网、tarpit和其他欺骗性技术可以用来减慢攻击者的速度,但是,这些方法很难跟上被发现的漏洞和被释放的攻击脚本的数量。为了解决这个问题,本文描述了一种在Nmap中对攻击脚本应用concolic执行的方法,以便自动生成可以欺骗脚本的易受攻击服务的轻量级伪造版本。通过以自动化和可扩展的方式这样做,该方法可以实现自定义蜜场的快速部署,该自定义蜜场利用concolic执行的结果来欺骗攻击者的脚本返回由蜜场选择的结果,使得脚本对于攻击者的使用不可靠。
Attackers rely upon a vast array of tools for automating attacksagainst vulnerable servers and services. It is often the case thatwhen vulnerabilities are disclosed, scripts for detecting and exploit-ing them in tools such asNmapandMetasploitare released soonafter, leading to the immediate identification and compromise ofvulnerable systems. Honeypots, honeynets, tarpits, and other decep-tive techniques can be used to slow attackers down, however, such approaches have difficulty keeping up with the sheer number of vulnerabilities being discovered and attacking scripts that are being released. To address this issue, this paper describes an approach for applying concolic execution on attacking scripts in Nmap in order to automatically generate lightweight fake versions of the vulnerable services that can fool the scripts. By doing so in an automated and scalable manner, the approach can enable rapid deployment of custom honeyfarms that leverage the results of concolic execution to trick an attacker's script into returning a result chosen by the honeyfarm, making the script unreliable for the use by the attacker.
