python多线程ssh爆破

0x01.About

爆弱口令时候写的一个python小脚本，主要功能是实现使用字典多线程爆破ssh，支持ip表导入，字典数据导入。

主要使用到的是python的paramiko模块和多线程threading模块。

那么，首先要准备的是字典dict、服务器ip表。

东西很简单，主要默认目录如下：

|--ssh.scan.py
|--/log:
    sshd
|--/dict:
    ip
    password

ip和password按照一行一个放置。

0x02.Code

下面上源码吧，文件保存为ssh.scan.py，查看使用方式：python ssh.scan.py -h

结果比较丑，自己爆自己服务器：

0x03.Solution

怎么办呢？防止被人爆菊，那就修改ssh默认登陆端口吧。修改方式主要是修改ssh配置文件：

1.修改iptables

首先要过防火墙，修改防火墙规则：

/sbin/iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 2333 -j ACCEPT

保存规则：

service iptables save

重启防火墙：

service iptables restart

2.修改ssh配置文件

cp /etc/ssh/ssh_config /etc/ssh/ssh_config.bak
cp /etc/ssh/sshd_config /etc/ssh/sshd_config.bak

修改ssh端口：

vim /etc/ssh/sshd_config

在端口#Port 22下面增加Port 2333

vim /etc/ssh/ssh_config

在端口#Port 22下面增加Port 2333

重启ssh服务：

service sshd restart

3.其他修改

限制用户的SSH访问

假设我们只要xiaocao和homeway用户能通过SSH使用系统，向sshd_config配置文件中添加

vim /etc/ssh/sshd_config

修改下面一行：

AllowUsers xiaocao homeway
