Which statement about dllinject is correct?

• A. It uploads an executable to the target machine.
• B. It provides VNC control.
• C. It executes a command on the target.
• D. It injects a DLL into the memory of the target machine.

Answer: (D)

DLL injection is the technique of loading a dynamic-link library into the address space of a running process so that the code in that library executes within the target’s context. The statement is correct because it captures the essence of how this method works: a library is brought into memory inside the target process, and its entry points (like DllMain) run under that process's privileges. This is different from simply uploading an executable to the target, which would place a new file on disk rather than run inside an existing process. It’s also not about providing remote control or issuing a standalone command to the target; instead, it leverages the target process’s memory and execution path to execute code via the injected DLL—commonly by allocating memory in the target, writing the DLL path, and creating a remote thread to load the library.
