# VNC

Adversaries may use Valid Accounts to remotely control machines using Virtual Network Computing(VNC). The adversary may then perform actions as the logged-on user.

VNC is a desktop sharing system that allows users to remotely control another computer's display by relaying mouse and keyboard inputs over the network. VNC does not necessarily use standard user credentials. Instead, a VNC client and server may be configured with sets of credentials that are only for VNC connections.
