三菱Q系列PLC以太网识别脚本(ICS Discovery Tools Releases)

melsecq

简介

三菱Q系列PLC以太网模块系统默认开放了TCP的5007端口和UDP的5006端口用于与GX软件进行通信,通过对通讯协议的分析,利用基于NMAP的脚本可以更方便快捷的实现对设备的识别和发现。

使用说明

Example1:
verify IP

nmap -script melsecq-discover-udp.nse -sU -p 5006 <host>
nmap -script melsecq-discover.nse -sT -p 5007 <host>

Example2:
verify IPList File

nmap -script melsecq-discover.nse -sT -p 5007 -iL <IPList File>

Example3:

melsecq-discover1

melsecq-discover2
