Offensive C# 2022

本课程教你从 C# 基础到使用 C# 调用 WinAPI。C# 是 Microsoft 开发的语言，可用于多种用途。C# 几乎可以通过 PInvoke 访问包括 WinAPI 在内的所有 Windows 组件。本课程还教授如何使用 Python Flask 作为后端和 C2 代理来构建自己的 C2 服务器。功能包括客户端连接管理器、文件浏览器、注册表浏览器等。C2的更多功能将不时添加。我们将看到如何使用默认绕过约束语言模式的 C2 编写传统的反向 shell。接下来我们将看到一些权限提升技术。接下来我们将使用 C# 枚举 Active Directory 并构建我们自己的自动化工具。我们将编写工具来自动化 Kerberoasting、支持 DCSync 的用户、委托攻击等等。我们将编写一个简单的加载程序，将 .NET 可执行文件加载到内存中并执行它们。接下来，我们将了解如何在 C# 中使用 WinAPI 函数，并为 Shellcode 注入、DLL 注入、调试检查、PE 文件后门等编写工具。我们还将看到 PE 文件格式的结构。

Learn WinAPI with C#

Requirements
Basic knowledge of Active Directory is optional
Description
This course teaches you all the way from fundamentals of C# to invoke WinAPI with C#. C# is Microsoft developed language which can be used for multiple purposes. C# gives almost all access to windows components including WinAPI via PInvoke. This course also teaches how to build your own C2 Server with Python Flask as backend and C2 agent. Features include Client connection manager, File explorer, Registry Explorer, etc. More features of C2 will be added from time to time. We will see how to code a traditional reverse shell with C2 which by default bypasses Constrained Language Mode. Next we will see some privilege escalation techniques. Next we will enumerate Active Directory with C# and build our own automation tools. We will write tools that automate Kerberoasting, DCSync capable users, Delegation Attacks and much more. We will write a simple loader that loads .NET executables in memory and executes them. Next we will see how to use WinAPI functions in C# and write tools for Shellcode Injection, DLL Injection, Debugging checks, Backdooring of PE Files and much more. We will also see the structure of PE File format.

No programming or Activedirectory experience required.

This course explains all the theory necessary to get started into building your own tools.
