SharPyShell
v1.3.0
SharpyShell是一个微小且混淆的ASP.NET Webshell，执行由加密的通道收到的命令，可在运行时记忆中编译它们。
SharpyShell仅支持在.NET框架上运行的C＃Web应用程序> = 2.0
VB不支持ATM。
python3 SharPyShell.py generate -p somepassword
python3 SharPyShell.py interact -u http://target.url/sharpyshell.aspx -p somepassword
Python版本> = 3.6
和
pip3 install -r requirements.txt
Sharpyshell是用Python编写的爆炸后框架，其能够：
该框架的主要目的是为渗透测试仪提供一系列工具，以简化后剥削阶段，一旦对IIS Weberver进行了成功的剥削。
该工具不是作为替代C2服务器的框架（IE MeterPreter，Empire，ECC ..）的替代，但是当您降落到完全受限的服务器时，应使用此工具，该服务器非常有限。
在此框架中，当您在目标服务器的CMD后面打字时，您将拥有PRIVESC，NETDISCOVERY和横向移动所需的所有工具。
此外，该框架的目的是在内存执行C＃代码和PowerShell模块中尽可能地偷偷摸摸。
Sharpyshell实施的混淆旨在逃避文件签名和网络签名ID。
对于逃避网络签名，已经开发了一个完全加密的通道，以发送命令和接收输出。
使用对运行时编译C＃代码的预编译的DLL上的反射，已经实现了文件签名的逃避。
