T0823 Graphical User Interface
High-Level Description
Adversaries may attempt to gain access to a machine via a Graphical User Interface (GUI) to enhance execution capabilities. Access to a GUI allows a user to interact with a computer in a more visual manner than a CLI. A GUI allows users to move a cursor and click on interface objects, with a mouse and keyboard as the main input devices, as opposed to just using the keyboard.
If physical access is not an option, then access might be possible via protocols such as VNC on Linux-based and Unix-based operating systems, and RDP on Windows operating systems. An adversary can use this access to execute programs and applications on the target machine.
Kill Chain Phase
Platforms: ICS
What to Check
How to Test
Identify Attack Surface
Determine if the target ICS/SCADA environment is susceptible to Graphical User Interface by examining operational technology systems and network architecture.
Assess Existing Defenses
Review whether mitigations for T0823 are in place. If defenses are absent or misconfigured, this technique may be exploitable in the ICS environment.
Remediation Guide
M0816 Mitigation Limited or Not Effective
Once an adversary has access to a remote GUI they can abuse system features, such as required HMI functions.
