Detection of an attack where the thrust direction has been altered outside of the expected parameters. Unauthorized changes to the thrust direction can lead to misalignment of the spacecraft�s trajectory and potential mission failure.

| 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. | |
