| ID | Name | Description | |
|---|---|---|---|
| IA-0001 | Compromise Supply Chain | Threat actors may manipulate or compromise products or product delivery mechanisms before the customer receives them in order to achieve data or system compromise. | |
| IA-0001.02 | Software Supply Chain | Threat actors may manipulate software binaries and applications prior to the customer receiving them in order to achieve data or system compromise. This attack can take place in a number of ways, including manipulation of source code, manipulation of the update and/or distribution mechanism, or replacing compiled versions with a malicious one. | |
| EX-0009 | Exploit Code Flaws | Threats actors may identify and exploit flaws or weaknesses within the software running on-board the target spacecraft. These attacks may be extremely targeted and tailored to specific coding errors introduced as a result of poor coding practices or they may target known issues in the commercial software components. | |
| EX-0009.01 | Flight Software | Threat actors may abuse known or unknown flight software code flaws in order to further the attack campaign. Some FSW suites contain API functionality for operator interaction. Threat actors may seek to exploit these or abuse a vulnerability/misconfiguration to maliciously execute code or commands. In some cases, these code flaws can perpetuate throughout the victim spacecraft, allowing access to otherwise segmented subsystems. | |
| EX-0009.02 | Operating System | Threat actors may exploit flaws in the operating system code, which controls the storage, memory management, provides resources to the FSW, and controls the bus. There has been a trend where some modern spacecraft are running Unix-based operating systems and establishing SSH connections for communications between the ground and spacecraft. Threat actors may seek to gain access to command line interfaces & shell environments in these instances. Additionally, most operating systems, including real-time operating systems, include API functionality for operator interaction. Threat actors may seek to exploit these or abuse a vulnerability/misconfiguration to maliciously execute code or commands. | |
| EX-0010 | Malicious Code | Threat actors may rely on other tactics and techniques in order to execute malicious code on the victim spacecraft. This can be done via compromising the supply chain or development environment in some capacity or taking advantage of known commands. However, once malicious code has been uploaded to the victim spacecraft, the threat actor can then trigger the code to run via a specific command or wait for a legitimate user to trigger it accidently. The code itself can do a number of different things to the hosted payload, subsystems, or underlying OS. | |
| EX-0010.01 | Ransomware | Threat actors may encrypt spacecraft data to interrupt availability and usability. Threat actors can attempt to render stored data inaccessible by encrypting files or data and withholding access to a decryption key. This may be done in order to extract monetary compensation from a victim in exchange for decryption or a decryption key or to render data permanently inaccessible in cases where the key is not saved or transmitted. | |
| EX-0010.02 | Wiper Malware | Threat actors may deploy wiper malware, which is a type of malicious software designed to destroy data or render it unusable. Wiper malware can spread through various means, software vulnerabilities (CWE/CVE), or by exploiting weak or stolen credentials. | |
| EX-0010.03 | Rootkit | Rootkits are programs that hide the existence of malware by intercepting/hooking and modifying operating system API calls that supply system information. Rootkits or rootkit enabling functionality may reside at the flight software or kernel level in the operating system or lower, to include a hypervisor, Master Boot Record, or System Firmware. | |
| EX-0010.04 | Bootkit | Adversaries may use bootkits to persist on systems and evade detection. Bootkits reside at a layer below the operating system and may make it difficult to perform full remediation unless an organization suspects one was used and can act accordingly. | |
| 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 Backdoor | 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). | |
| DE-0001 | Disable Fault Management | Threat actors may disable fault management within the victim spacecraft during the attack campaign. During the development process, many fault management mechanisms are added to the various parts of the spacecraft in order to protect it from a variety of bad/corrupted commands, invalid sensor data, and more. By disabling these mechanisms, threat actors may be able to have commands processed that would not normally be allowed. | |
| DE-0007 | Evasion via Rootkit | Rootkits are programs that hide the existence of malware by intercepting/hooking and modifying operating system API calls that supply system information. Rootkits or rootkit enabling functionality may reside at the flight software or kernel level in the operating system or lower, to include a hypervisor, Master Boot Record, or System Firmware. | |
| DE-0008 | Evasion via Bootkit | Adversaries may use bootkits to persist on systems and evade detection. Bootkits reside at a layer below the operating system and may make it difficult to perform full remediation unless an organization suspects one was used and can act accordingly. | |
| DE-0009 | Camouflage, Concealment, and Decoys (CCD) | This technique deals with the more physical aspects of CCD that may be utilized by threat actors. There are numerous ways a threat actor may utilize the physical operating environment to their advantage, including powering down and laying dormant within debris fields as well as launching EMI attacks during space-weather events. | |
| DE-0009.05 | Corruption or Overload of Ground-Based SDA Systems | Threat actors may target the ground-based systems and data pipelines that support Space Domain Awareness (SDA), either by corrupting key data sources, manipulating tracking information, or overloading the ingestion architecture. The objective is to blind or confuse decision-makers and automated systems responsible for monitoring and responding to on-orbit activity. This includes compromising or spoofing telemetry, TLEs, sensor feeds, radar/optical returns, or orbital prediction services used by tracking centers. It also includes the enumeration and exploitation of analytic infrastructures, such as AI/ML-enhanced SDA platforms. In cases where SDA systems leverage AI/ML inference for object detection and decision support, attackers may seek to degrade model performance by flooding the data pipeline with misleading, noisy, adversarial, or low-quality sensor inputs. These disruptions aim to delay detection of threats, generate false positives, or cause resource exhaustion in SDA fusion and alerting systems. This sub-technique differs from onboard deception (e.g., sensor spoofing) by targeting the terrestrial decision support infrastructure, potentially affecting multiple spacecraft or operators simultaneously. | |

|
| SV-SP-7 |
Software can be broken down into three levels (operating system and drivers’ layer, data handling service layer, and the application layer). Highest impact on system is likely the embedded code at the BIOS, kernel/firmware level. Attacking the on-board operating systems. Since it manages all the programs and applications on the computer, it has a critical role in the overall security of the system. Since threats may occur deliberately or due to human error, malicious programs or persons, or existing system vulnerability mitigations must be deployed to protect the OS. |

The TT&C is the lead contributor to satellite failure over the first 10 years on-orbit, around 20% of the time. The failures due to gyro are around 12% between year one and 6 on-orbit and then ramp up starting around year six and overtake the contributions of the TT&C subsystem to satellite failure. Need to ensure equipment is not counterfeit and the supply chain is sound. |

Ideally these artifacts would be rated SECRET or higher and stored on classified networks. Mission sensitive information can typically include a wide range of candidate material: the functional and performance specifications, the RF ICDs, databases, scripts, simulation and rehearsal results/reports, descriptions of uplink protection including any disabling/bypass features, failure/anomaly resolution, and any other sensitive information related to architecture, software, and flight/ground /mission operations. This could all need protection at the appropriate level (e.g., unclassified, SBU, classified, etc.) to mitigate levels of cyber intrusions that may be conducted against the project’s networks. Stand-alone systems and/or separate database encryption may be needed with controlled access and on-going Configuration Management to ensure changes in command procedures and critical database areas are tracked, controlled, and fully tested to avoid loss of science or the entire mission. |

| The [organization] shall distribute documentation to only personnel with defined roles and a need to know.{SV-CF-3,SV-AV-5}{CM-12,CP-2,SA-5,SA-10} | Least privilege and need to know should be employed with the protection of all documentation. Documentation can contain sensitive information that can aid in vulnerability discovery, detection, and exploitation. For example, command dictionaries for ground and space systems should be handles with extreme care. Additionally, design documents for missions contain many key elements that if compromised could aid in an attacker successfully exploiting the system. |

Blindly accepting the firmware is free of weakness is unacceptable for high assurance missions. The intent is to not blindly accept firmware from unknown sources and assume it is secure. This is meant to apply to firmware the vendors are not developing internally. In-house developed firmware should be going through the vendor's own testing program and have high assurance it is secure. When utilizing firmware from other sources, "expecting" does not meet this requirement. Each supplier needs to provide evidence to support that claim that their firmware they are getting is genuine and secure. |
