Detection of sudden changes or spikes in sensor data that do not correlate with known physical conditions, indicating potential anomalies. Such behavior, when combined with unexpected actuator operations like unintended thruster firings or erratic reaction wheel speeds, suggests possible malicious interference or system faults. This can be detected through baselining/normalization of spacecraft speeds using machine learning algorithms to identify deviations from expected patterns.
| ID | Name | Description | |
| EX-0012 | Modify On-Board Values | Threat actors may perform specific commands in order to modify onboard values that the victim SV relies on. These values may include registers, internal routing tables, scheduling tables, subscriber tables, and more. Depending on how the values have been modified, the victim SV may no longer be able to function. | |
| EX-0012.08 | Attitude Determination & Control Subsystem | Threat actors may target the onboard values for the Attitude Determination and Control subsystem of the victim SV. This subsystem determines the positioning and orientation of the SV. Throughout the SV's lifespan, this subsystem will continuously correct it's orbit, making minor changes to keep the SV aligned as it should. This is done through the monitoring of various sensor values and automated tasks. If a threat actor were to target these onboard values and modify them, there is a chance that the automated tasks would be triggered to try and fix the orientation of the SV. This can cause the wasting of resources and, possibly, the loss of the SV, depending on the values changed. | |
