SharpStrike：基于C#实现的后渗透漏洞利用研究工具

关于SharpStrike

SharpStrike是一款基于C#开发的后渗透工具，该工具可以使用CIM或WMI来查询远程系统。除此之外，该工具还可以使用研究人员提供的凭证信息或使用当前的用户会话。

注意：SharpStrike中的某些命令将使用PowerShell结合WMI以实现其功能。

SharpStrike可以帮助广大研究人员收集关于目标远程系统的数据、执行命令以及提取数据等等。该工具允许使用WMI或CIM来跟远程系统进行连接，而CIM的使用则需要我们获取到目标系统的管理员权限。

解决方案架构

SharpStrike由三个主组件构成：

服务层：提供核心功能并由UI层使用（cs、ExecuteWMI.cs、ExecuteCIM.cs）；

模型：包含整个项目所有共享的数据类型；

用户接口：GUI/命令行终端；

工具安装

我们可以选择直接使用该项目【Releases页面】所提供的预构建版本，不过这个版本是在调式模式下构建的。

手动构建

首先，我们需要使用下列命令将该项目源码克隆至本地：

git clone https://github.com/iomoath/SharpStrike.git

接下来，在Visual Studio中加载项目中的SharpStrike.sln文件。
选择顶部菜单中的“构建”项，然后构建解决方案。
此时将会生成两个版本的SharpStrike，即带有GUI界面的WinForms和命令行终端应用程序，每一个版本都实现的是相同的功能。
