Detection of an unplanned orbit adjustment executed by the Attitude Determination and Control subsystem. This indicates that the system may have been manipulated to trigger unnecessary orbit corrections, leading to resource wastage.

| 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-0012.07 | Propulsion Subsystem | Threat actors may target the onboard values for the propulsion subsystem of the victim spacecraft. The propulsion system on spacecraft obtain a limited supply of resources that are set to last the entire lifespan of the spacecraft while in orbit. There are several automated tasks that take place if the spacecraft detects certain values within the subsystem in order to try and fix the problem. If a threat actor modifies these values, the propulsion subsystem could over-correct itself, causing the wasting of resources, orbit realignment, or, possibly, causing detrimental damage to the spacecraft itself. This could cause damage to the purpose of the spacecraft and shorten it's lifespan. | |
| 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. | |
