Which technique provides remote VNC control of the target's GUI?

• A. Dllinject
• B. Upexec
• C. Vncinject
• D. Meterpreter

Answer: (C)

Injecting a VNC server into a running target process to gain remote GUI access. Vncinject refers to placing a VNC server component inside the target’s already running application so you can connect with a VNC client to view and control that target’s graphical interface from outside. This technique leverages the target’s session context, letting you observe and interact with the GUI as if you were sitting at the machine, often using a password you’ve configured during the injection.

The other options don’t describe this specific approach. Dllinject is about loading a DLL into a process for arbitrary code execution, not about providing a VNC-based remote desktop. Upexec is not the standard term for remote GUI control via VNC. Meterpreter is a versatile post-exploitation payload but doesn’t imply injecting a VNC server to take over the GUI via VNC.
