The use of undetected DLL injectors poses significant implications to individuals and organizations:
Instead of creating a new thread, the injector "hijacks" an existing, legitimate thread in the game, forces it to run the shellcode, and then returns it to its original task.
// 4. Allocate memory in target process using NtAllocateVirtualMemory (syscall) // 5. Write the DLL path into that memory // 6. Call NtCreateThreadEx (via syscall) pointing to the real LoadLibraryA address
The injector manually parses the DLL's headers and copies the sections into the target process.
To create an "undetected" DLL injector, one must understand common detection methods and how to evade them:
Undetected DLL injectors are designed to evade detection by traditional security measures, such as antivirus software and intrusion detection systems. These injectors use various techniques to remain undetected, including:
