前言

由于前段时间，加强安全防护，需要扫描内网的弱口令的服务器，并对其修改密码。

于是写了一个基于nmap、hydra的弱密码空令检测脚本简略的脚本。

/script/Break/ip/ce_ip.txt中提供的是需要检测的ip,但是由于其中的一些服务器启用了tcp_wrapper,会导致hydra破解的时候，一直出现”[ERROR] could not connect to target port 22“，只好先用nmap对服务的版本进行查看，并将其排除，因此导致前期很缓慢。有其他好方法的，请不吝赐教。

#!/bin/bash

> /script/Break/ip/break_ip.txt
> /script/Break/log/nmap.log
 
for t_nmap in `cat /script/Break/ip/ce_ip.txt`
do  
	
	nmap -sV $t_nmap > /script/Break/log/nmap.log

	sleep 50
    
	echo $t_nmap
	cat /script/Break/log/nmap.log |grep tcpwrap
	
	if [ $? -eq 0 ];then
		echo "$t_nmap open tcpwrap" >> /script/Break/log/tcpwrap_log.txt
		echo "$t_nmap open tcpwrap"
   else
		echo "$t_nmap Password cracking is possible" >> /script/Break/log/tcpwrap_log.txt
	    echo "$t_nmap Password cracking is possible"
		echo "$t_nmap" >> /script/Break/ip/break_ip.txt
	fi	
    

done 

echo "Scanning is complete and the next step is started..."  >>  /script/Break/log/tcpwrap_log.txt
echo "Scanning is complete and the next step is started..."

>/script/Break/log/hydra_ssh.log
>/script/Break/password.txt

for hyd in `cat /script/Break/ip/break_ip.txt`

do  
	echo "$hyd  password is being cracked"

#hydra的破解速率，可根据需求进行调整
    
	hydra -L /script/Break/lib/userlist -P /script/Break/lib/passwdlist -vV -t 8  -e ns $hyd ssh  >> /script/Break/log/hydra_ssh.log 
    
	cat /script/Break/log/hydra_ssh.log |grep "\[ssh\]"  >> /script/Break/password.txt
done


echo "sucessful!"
