Overview

Remote DLL Injection with Timer-based Shellcode Execution is a technique that leverages the Windows thread pool to execute shellcode. Using the classic DLL injection with CreateThreadpoolTimer to run shellcode in-memory using legit system threads, stealthy, and likely to slip past modern defenses

This approach introduces a stealthy execution using Timer-based Shellcode Execution

🧩 Core Components

🛠 Main Injector (ConsoleApplication5.cpp)

• Process enumeration and targeting logic
• DLL injection using CreateRemoteThread and LoadLibraryW
• Error handling and execution status reporting

⏲ Timer DLL (Dll1.cpp)

• Timer-based shellcode execution implementation
• TP_CALLBACK_ENVIRON structure setup for thread pool configuration
• Execution of shellcode via the timer callback
