Monitors critical subsystem registers for unauthorized value modifications that could disrupt spacecraft functionality or subsystem workflows. Detects register values deviating from expected baselines within critical subsystems, potentially indicating unauthorized tampering.

| EX-0010 | Inject Malicious Code | Threat actors may rely on other tactics and techniques in order to inject malicious code into the victim spacecraft. This can be done via compromising the supply chain or development environment in some capacity or taking advantage of known commands. However, once malicious code has been uploaded to the victim spacecraft, the threat actor can then trigger the code to run via a specific command or wait for a legitimate user to trigger it accidently. The code itself can do a number of different things to the hosted payload, subsystems, or underlying OS. | |
| EX-0012.01 | Registers | Threat actors may target the internal registers of the victim spacecraft in order to modify specific values as the FSW is functioning or prevent certain subsystems from working. Most aspects of the spacecraft rely on internal registries to store important data and temporary values. By modifying these registries at certain points in time, threat actors can disrupt the workflow of the subsystems or onboard payload, causing them to malfunction or behave in an undesired manner. | |
