如何使用evilscan 扫描网络

Centos8

npm(Node包管理器)

从github中克隆该仓库，如果系统没有安装git和npm需要提前安装：

[root@localhost ~]# yum -y install git npm
[root@localhost ~]# git clone https://github.com/eviltik/evilscan.git

进入evilscan工作目录并安装：

[root@localhost ~]# cd evilscan/
[root@localhost evilscan]# npm install -g evilscan

                  (i.e a /24 network with port range 0-65535)
  --display       display result format (json,xml,console)
                  default console
  --outfile       dump result in a file

  --json          shortcut for --display=json
  --xml           shortcut for --display=xml
  --console       shortcut for --display=console
  --help          display help
  --about         display about
  --version       display version number

语法：

 evilscan  [options]

扫描网络中的一台主机上的0-4000端口，抓取banner并仅显示open的端口：

[root@localhost ~]# evilscan 192.168.0.10 --port=0-4000 --banner
192.168.0.10|139||open                                                                                    
192.168.0.10|135||open                                                                                    
192.168.0.10|110||open                                                                                    
192.168.0.10|25||open                                                                                     
192.168.0.10|445||open                                                                                    
192.168.0.10|2381||open                                                                                   
192.168.0.10|2301||open                                                                                   
192.168.0.10|3389||open           

扫描网络中的一台主机上的0-100端口，抓取banner，仅显示打开的端口，使用json格式输出，每秒显示进度状态：

[root@localhost ~]# evilscan 192.168.0.13 --port=0-100 --banner --isopen --istimeout --progress --json
{"_timeStart":"N/A","_timeElapsed":"N/A","_jobsTotal":100,"_jobsRunning":0,"_jobsDone":0,"_progress":0,"_concurrency":500,"_status":"Starting","_message":"Starting"}
{"_timeStart":1628685339594,"_timeElapsed":999,"_jobsTotal":100,"_jobsRunning":100,"_jobsDone":0,"_progress":0,"_concurrency":500,"_status":"Running","_message":"Scanning 192.168.0.13:100"}
{"_timeStart":1628685339594,"_timeElapsed":2003,"_jobsTotal":100,"_jobsRunning":100,"_jobsDone":0,"_progress":0,"_concurrency":500,"_status":"Running","_message":"Scanning 192.168.0.13:100"}
{"ip":"192.168.0.13","port":25,"status":"open"}
{"ip":"192.168.0.13","port":22,"banner":"SSH-2.0-OpenSSH_7.9-hpn14v15//r//n","status":"open"}
{"ip":"192.168.0.13","port":80,"status":"open"}
{"_timeStart":1628685339594,"_timeElapsed":2019,"_jobsTotal":100,"_jobsRunning":0,"_jobsDone":100,"_progress":100,"_concurrency":500,"_status":"Finished","_message":"Scanned 192.168.0.13:80"}

提示：并发数默认为100。如果想扫描大量的 ip/端口范围，可以使用 --concurrency 选项（例如 1000）。

如果要突破 1024 个打开套接字的限制，使用下面命令更新限制参数：

ulimit -u unlimited

Evilscan 是一个网络扫描器，它运行在 NodeJS 环境中。有许多种选项，允许用户扫描单个 IP 地址或一个范围的IP。它还允许用户选择扫描单个端口或一组端口。
