T0852 Screen Capture
High-Level Description
Adversaries may attempt to perform screen capture of devices in the control system environment. Screenshots may be taken of workstations, HMIs, or other devices that display environment-relevant process, device, reporting, alarm, or related data. These device displays may reveal information regarding the ICS process, layout, control, and related schematics. In particular, an HMI can provide a lot of important industrial process information. Analysis of screen captures may provide the adversary with an understanding of intended operations and interactions between critical devices.
Kill Chain Phase
- Collection (TA0100)
Platforms: ICS
What to Check
- Identify if Screen Capture technique is applicable to target ICS environment
- Check ICS/SCADA systems for indicators of Screen Capture
- Verify mitigations are bypassed or absent (1 known mitigations)
- Assess detection coverage (1 detection strategies)
How to Test
Identify Attack Surface
Determine if the target ICS/SCADA environment is susceptible to Screen Capture by examining operational technology systems and network architecture.
Assess Existing Defenses
Review whether mitigations for T0852 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
Preventing screen capture on a device may require disabling various system calls supported by the operating systems (e.g., Microsoft WindowsGraphicsCaputer APIs), however, these may be needed for other critical applications.
