0x01 Compiler前言
说明:Microsoft.Workflow.Comiler.exe是.NET Framework默认自带的一个实用工具，用户能够以XOML工作流文件的形式提供一个序列化工作流来执行任意未签名的代码。
Microsoft.Workflow.Comiler.exe需要两个命令行参数，第一个参数必须是一个XML文件（由一个序列化CompilerInput对象构成）的路径，第二个参数则是写入序列化编译结果的文件路径。
Windows 7 默认位置：
C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Workflow.Compiler.exeC:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Workflow.Compiler.exe
0x02 执行流程
攻击流程如下：
1.将制作的XOML文件存储到目标磁盘中，XOML文件中应包含攻击者提供的C#或VB.Net代码以供编译、加载和调用。攻击逻辑需在类构造函数中实现，该类派生自System.Workflow.ComponetModel.Activity类。
2.将包含序列化CompilerInput对象的XML文件存储到目标磁盘中。
3.提供XML路径，执行Microsoft.Workflow.Comiler.exe。
下面给出的是Microsoft.Workflow.Comiler.exe的调用样例：
C:\Windows\Microsoft.Net\Framework64\v4.0.30319\Microsoft.Workflow.Compiler.exetest.xml results.xml

也可以用nc：
B) 结合meterpreter
注：payload.cs需要用到System.Workflow.Activities
