Hacking the Exception Handler: A Tale of DirectX, Flash, and Code Modification

A team encountered a frustrating issue while using `SetUnhandledExceptionFilter` for unhandled exception handling: Direct3D and Flash were installing their own exception filters, rendering the team's solution ineffective. To resolve this, they employed a bold strategy: directly disabling the `SetUnhandledExceptionFilter` function via code modification to ensure their exception handler took precedence. The article details the process of code modification, including obtaining the function address, verifying the initial instructions, and utilizing `VirtualProtect` and `FlushInstructionCache` APIs for code replacement. Their solution restored proper exception reporting functionality.
