Detection of unauthorized or irregular command executions within the Attitude Control System of a spacecraft, indicating possible attempts to manipulate the spacecraft's orientation and trajectory. These activities can suggest malicious intent to disrupt or take control of the spacecraft's operations.
| ID | Name | Description | |
| EX-0012 | Modify On-Board Values | Threat actors may perform specific commands in order to modify onboard values that the victim spacecraft 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 spacecraft 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 spacecraft. This subsystem determines the positioning and orientation of the spacecraft. Throughout the spacecraft's lifespan, this subsystem will continuously correct it's orbit, making minor changes to keep the spacecraft 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 spacecraft. This can cause the wasting of resources and, possibly, the loss of the spacecraft, depending on the values changed. | |
