关于SharpSCCM
SharpSCCM是一款功能强大的横向渗透和凭证收集工具，该工具主要利用了微软终端配置管理器（SCCM）来实现其功能，并能够通过访问SCCM管理终端GUI来实现横向渗透和凭证收集。
功能介绍
1、后渗透功能，支持横向渗透；
2、支持从SCCM客户端请求NTLM认证；
3、支持收集网络访问账号（NAA）的凭证信息；
4、请求和反混淆NAA凭证；
5、支持滥用新发现的攻击原语来强制来自SCCM服务器的NTLM身份验证；
工具下载
广大研究人员可以使用下列命令将该项目源码克隆至本地：
git clone https://github.com/Mayyhem/SharpSCCM.git
项目构建
将项目源码克隆至本地之后，在Visual Studio中打开SharpSCCM.sln，然后选择目标，比如说Release > x64。
接下来，构建解决方案（Ctrl + Shift + B）即可。
此时，将在目标路径下生成一个SharpSCCM程序集，其中包含了所有的工具及依赖组件，路径为.\SharpSCCM\bin\x64\Release\SharpSCCM_merged.exe。
命令行使用
命令样例：
SharpSCCM.exe [command] [options]
自命令样例：
add 支持将对象添加到其他对象
get 查询指定对象，并显示对象内容
exec 从指定UNC路径执行一个应用程序，或从客户端设备请求NTLM身份认证
invoke 在服务器上执行或调用操作
local 与本地工作站/服务器交互
new 在服务器上创建新的对象
remove 从服务器删除对象
工具使用
从本地SCCM客户端设备导出和解密NAA凭证
通过WMI导出NAA并使用DPAPI主密钥进行解密：
SharpSCCM.exe local naa wmi
样例输出：
.\SharpSCCM.exe local naa wmi
