Detection of unauthorized modifications to the software-defined radio (SDR) configuration, potentially allowing a threat actor to establish persistent access via radio communication. SDRs are reconfigurable by design therefore, integrity protection is important and detection of all modifications are necessary.
| ID | Name | Description | |
| IA-0002 | Compromise Software Defined Radio | Threat actors may target software defined radios due to their software nature to establish C2 channels. Since SDRs are programmable, when combined with supply chain or development environment attacks, SDRs provide a pathway to setup covert C2 channels for a threat actor. | |
| PER-0002 | Backdoor | Threat actors may find and target various backdoors, or inject their own, within the victim spacecraft in the hopes of maintaining their attack. | |
| PER-0002.02 | Software | Threat actors may inject code to create their own backdoor to establish persistent access to the spacecraft. This may be done through modification of code throughout the software supply chain or through modification of the software-defined radio configuration (if applicable). | |
| EXF-0006.01 | Software Defined Radio | Threat actors may target software defined radios due to their software nature to setup exfiltration channels. Since SDRs are programmable, when combined with supply chain or development environment attacks, SDRs provide a pathway to setup covert exfiltration channels for a threat actor. | |
