This IOC detects repeated burn commands where the duration exceeds safe operational limits. Multiple consecutive commands with long durations may indicate a deliberate attack aiming to destabilize the spacecraft's orbit or waste fuel resources.
| 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-0012.07 | Propulsion Subsystem | Threat actors may target the onboard values for the propulsion subsystem of the victim SV. The propulsion system on SVs obtain a limited supply of resources that are set to last the entire lifespan of the SV while in orbit. There are several automated tasks that take place if the SV 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 SV itself. This could cause damage to the purpose of the SV and shorten it's lifespan. | |
