Unity Mono游戏逆向实战：Frida Hook绕过碰撞死亡判定在移动游戏开发与安全分析领域，Unity引擎因其跨平台特性被广泛应用，其脚本后端Mono和IL2CPP是核心执行框架。Mono运行时通过解释或编译C#字节码来驱动游戏逻辑，其核心函数mono_runtime_invoke是所有托管方法调用的必经枢纽。理解这一原理对于游戏逻辑分析、安全测试和性能优化具有重要技术价值，尤其在动态插桩和运行时行为干预场景中。通过Hook此函数，可以在不修改原始程序集的情况下，实现对特定游戏逻辑（如碰撞检测、状态判定）的精准拦截与修改。本文以一款经典Unity Mono游戏为例，结阅读详情

微信PC端Hook技术解析：基于2.8.0.121版本的自动化与逆向工程实践 Hook技术是Windows平台软件逆向与自动化开发的核心手段，其本质是通过内存注入或API拦截实现对目标程序执行流程的监控与修改。在技术原理上，Inline Hook通过修改函数入口指令实现跳转，结合DLL注入技术将自定义代码植入目标进程。这项技术的工程价值在于能够突破软件封闭性，实现功能扩展与流程自动化。在应用场景中，Hook技术常用于自动化测试、效率工具开发和安全研究领域。本文聚焦于微信PC客户端2.8.0.121版本的Hook实现，详细解析了通过DLL劫持和HTTP服务构建自动化控制接口的技术方案，阅读详情

FileSystemWatcher

Use FileSystemWatcher to watch for changes in a specified directory. You can watch for changes in files and subdirectories of the specified directory. You can create a component to watch files on a local computer, a network drive, or a remote computer.

To watch for changes in all files, set the Filter property to an empty string ("") or use wildcards ("*.*"). To watch a specific file, set the Filter property to the file name. For example, to watch for changes in the file MyDoc.txt, set the Filter property to "MyDoc.txt". You can also watch for changes in a certain type of file. For example, to watch for changes in text files, set the Filter property to "*.txt".
