Linux下使用Evilscan掃描網(wǎng)絡(luò)

Evilscan 是一個(gè)網(wǎng)絡(luò)掃描器,它運(yùn)行在 NodeJS 環(huán)境中。有許多種選項(xiàng),允許用戶掃描單個(gè) IP 地址或一個(gè)范圍的IP。它還允許用戶選擇掃描單個(gè)端口或一組端口。

環(huán)境

Centos8

npm(Node包管理器)

安裝

從github中克隆該倉庫,如果系統(tǒng)沒有安裝git和npm需要提前安裝:

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

進(jìn)入evilscan工作目錄并安裝:

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

如何使用evilscan 掃描網(wǎng)絡(luò)如何使用evilscan 掃描網(wǎng)絡(luò)

使用實(shí)例

語法:

 evilscan  [options]

掃描網(wǎng)絡(luò)中的一臺(tái)主機(jī)上的0-4000端口,抓取banner并僅顯示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          

掃描網(wǎng)絡(luò)中的一臺(tái)主機(jī)上的0-100端口,抓取banner,僅顯示打開的端口,使用json格式輸出,每秒顯示進(jìn)度狀態(tài):

[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:并發(fā)數(shù)默認(rèn)為100。如果想掃描大量的 ip/端口范圍,可以使用 --concurrency 選項(xiàng)(例如 1000)。

如果要突破 1024 個(gè)打開套接字的限制,使用下面命令更新限制參數(shù):

ulimit -u unlimited
