TestTarget32

TestTarget32

TestTarget32 is a tiny .NET Framework 4.8 x86 console program meant to be an easy target for:

• native API tracing hooks (e.g. MessageBoxW, CreateFileW)
• managed method resolution/tracing via ManagedHookHostProj + Frida Interceptor.attach()

This is intentionally not “realistic”; it exists so you can validate your build + injection pipeline quickly.

Build

Open:

• examples\\TestTarget32\\TestTarget32.sln

Build:

• Release | x86

Or from a Developer Command Prompt:

msbuild examples\\TestTarget32\\TestTarget32.sln /p:Configuration=Release /p:Platform=x86

Run

Start the EXE and note the PID printed on startup.

Then use the keyboard menu:

• M -> calls MessageBoxW
• F -> writes a temp file (File.WriteAllText), typically triggers CreateFileW
• P -> calls managed PotatoVerifier.CheckIsPotato(string)
• O -> calls managed overload PotatoVerifier.CheckIsPotato(string,int)

Hooking

Use InjectorCli to attach or spawn.

Native hooks:

• examples\\InjectorCli\\hooks\\trace_messagebox.js
• examples\\InjectorCli\\hooks\\hook_createfilew.js
• examples\\InjectorCli\\hooks\\change_messagebox_text.js

Managed tracing:

• examples\\ManagedHookHostProj\\agent\\resolve_and_trace_managed.js

Update that agent script with:

• targetAssemblyPath -> path to TestTarget32.exe
• targetTypeName -> TestTarget32.PotatoVerifier
• targetMethodName -> CheckIsPotato
• paramSig -> System.String (or System.String|System.Int32 for the overload)
