Detection of unusually high latency in downlink communications, which may indicate that an attacker is interfering with telemetry transmission to delay or disrupt communication between the spacecraft and ground controllers.
| ID | Name | Description | |
| DE-0002 | Prevent Downlink | Threat actors may target the downlink connections to prevent the victim spacecraft from sending telemetry to the ground controllers. Telemetry is the only method in which ground controllers can monitor the health and stability of the spacecraft while in orbit. By disabling this downlink, threat actors may be able to stop mitigations from taking place. | |
| DE-0002.01 | Inhibit Ground System Functionality | Threat actors may utilize ground-system presence to inhibit the ground system software's ability to process (or display) telemetry, effectively leaving ground controllers unaware of vehicle activity during this time. Telemetry is the only method in which ground controllers can monitor the health and stability of the spacecraft while in orbit. By disabling this downlink, threat actors may be able to stop mitigations from taking place. | |
| EXF-0003.02 | Downlink Intercept | Threat actors may target the downlink connection from the victim spacecraft in order to exfiltrate telemetry or payload data. This data can include health information of the spacecraft or mission data that is being collected/analyzed on the spacecraft. Downlinked data can even include mirrored command sessions which can be used for future campaigns or to help perpetuate other techniques. | |
