- physical and support environments |
| RD-0002 |
Compromise Infrastructure |
Threat actors may compromise third-party infrastructure that can be used for future campaigns or to perpetuate other techniques. Infrastructure solutions include physical devices such as antenna, amplifiers, and convertors, as well as software used by satellite communicators. Instead of buying or renting infrastructure, a threat actor may compromise infrastructure and use it during other phases of the campaign's lifecycle. |
|
RD-0002.01 |
Mission-Operated Ground System |
Threat actors may compromise mission owned/operated ground systems that can be used for future campaigns or to perpetuate other techniques.

|
RD-0002.02 |
3rd Party Ground System |
Threat actors may compromise access to third-party ground systems that can be used for future campaigns or to perpetuate other techniques.

By compromising this infrastructure, threat actors can stage, launch, and execute an operation. |
| RD-0003 |
Obtain Capabilities |
Threat actors may buy and/or steal capabilities that can be used for future campaigns or to perpetuate other techniques. Rather than developing their own capabilities in-house, threat actors may purchase, download, or steal them. Activities may include the acquisition of malware, software, exploits, and information relating to vulnerabilities. Threat actors may obtain capabilities to support their operations throughout numerous phases of the campaign lifecycle. |
|
RD-0003.02 |
Cryptographic Keys |
Threat actors may obtain encryption keys as they are used for the main commanding of the target spacecraft or any of its subsystems/payloads. Once obtained, threat actors may use any number of means to command the spacecraft without needing to go through a legitimate channel. These keys may be obtained through reconnaissance of the ground system or retrieved from the victim spacecraft. |
| RD-0004 |
Stage Capabilities |
Threat actors may upload, install, or otherwise set up capabilities that can be used for future campaigns or to perpetuate other techniques. To support their operations, a threat actor may need to develop their own capabilities or obtain them in some way in order to stage them on infrastructure under their control. These capabilities may be staged on infrastructure that was previously purchased or rented by the threat actor or was otherwise compromised by them. |
|
RD-0004.01 |
Identify/Select Delivery Mechanism |
Threat actors may identify, select, and prepare a delivery mechanism in which to attack the space system (i.e., communicate with the victim spacecraft, deny the ground, etc.) to achieve their desired impact. This mechanism may be located on infrastructure that was previously purchased or rented by the threat actor or was otherwise compromised by them. The mechanism must include all aspects needed to communicate with the victim spacecraft, including ground antenna, converters, and amplifiers. |
|
RD-0004.02 |
Upload Exploit/Payload |
Threat actors may upload exploits and payloads to a third-party infrastructure that they have purchased or rented or stage it on an otherwise compromised ground station. Exploits and payloads would include files and commands to be uploaded to the victim spacecraft in order to conduct the threat actor's attack. |
| 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-0001.03 |
Hardware Supply Chain |
Threat actors may manipulate hardware components in the victim spacecraft prior to the customer receiving them in order to achieve data or system compromise. The threat actor can insert backdoors and give them a high level of control over the system when they modify the hardware or firmware in the supply chain. This would include ASIC and FPGA devices as well. |
| 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. |
| IA-0004 |
Secondary/Backup Communication Channel |
Threat actors may compromise alternative communication pathways which may not be as protected as the primary pathway. Depending on implementation the contingency communication pathways/solutions may lack the same level of security (i.e., physical security, encryption, authentication, etc.) which if forced to use could provide a threat actor an opportunity to launch attacks. Typically these would have to be coupled with other denial of service techniques on the primary pathway to force usage of secondary pathways. |
|
IA-0004.01 |
Ground Station |
Threat actors may establish a foothold within the backup ground/mission operations center (MOC) and then perform attacks to force primary communication traffic through the backup communication channel so that other TTPs can be executed (man-in-the-middle, malicious commanding, malicious code, etc.). While an attacker would not be required to force the communications through the backup channel vice waiting until the backup is used for various reasons. Threat actors can also utilize compromised ground stations to chain command execution and payload delivery across geo-separated ground stations to extend reach and maintain access on spacecraft. The backup ground/MOC should be considered a viable attack vector and the appropriate/equivalent security controls from the primary communication channel should be on the backup ground/MOC as well. |
|
IA-0004.02 |
Receiver |
Threat actors may target the backup/secondary receiver on the space vehicle as a method to inject malicious communications into the mission. The secondary receivers may come from different supply chains than the primary which could have different level of security and weaknesses. Similar to the ground station, the communication through the secondary receiver could be forced or happening naturally. |
| IA-0006 |
Compromise Hosted Payload |
Threat actors may compromise the target spacecraft hosted payload to initially access and/or persist within the system. Hosted payloads can usually be accessed from the ground via a specific command set. The command pathways can leverage the same ground infrastructure or some host payloads have their own ground infrastructure which can provide an access vector as well. Threat actors may be able to leverage the ability to command hosted payloads to upload files or modify memory addresses in order to compromise the system. Depending on the implementation, hosted payloads may provide some sort of lateral movement potential. |
| IA-0007 |
Compromise Ground System |
Threat actors may initially compromise the ground system in order to access the target spacecraft. Once compromised, the threat actor can perform a multitude of initial access techniques, including replay, compromising FSW deployment, compromising encryption keys, and compromising authentication schemes. Threat actors may also perform further reconnaissance within the system to enumerate mission networks and gather information related to ground station logical topology, missions ran out of said ground station, birds that are in-band of targeted ground stations, and other mission system capabilities. |
|
IA-0007.01 |
Compromise On-Orbit Update |
Threat actors may manipulate and modify on-orbit updates before they are sent to the target spacecraft. This attack can be done in a number of ways, including manipulation of source code, manipulating environment variables, on-board table/memory values, or replacing compiled versions with a malicious one. |
|
IA-0007.02 |
Malicious Commanding via Valid GS |
Threat actors may compromise target owned ground systems components (e.g., front end processors, command and control software, etc.) that can be used for future campaigns or to perpetuate other techniques. These ground systems components have already been configured for communications to the victim spacecraft. By compromising this infrastructure, threat actors can stage, launch, and execute an operation. Threat actors may utilize these systems for various tasks, including Execution and Exfiltration. |
| IA-0009 |
Trusted Relationship |
Access through trusted third-party relationship exploits an existing connection that has been approved for interconnection. Leveraging third party / approved interconnections to pivot into the target systems is a common technique for threat actors as these interconnections typically lack stringent access control due to the trusted status. |
|
IA-0009.01 |
Mission Collaborator (academia, international, etc.) |
Threat actors may seek to exploit mission partners to gain an initial foothold for pivoting into the mission environment and eventually impacting the spacecraft. The complex nature of many space systems rely on contributions across organizations, including academic partners and even international collaborators. These organizations will undoubtedly vary in their system security posture and attack surface. |
|
IA-0009.02 |
Vendor |
Threat actors may target the trust between vendors and the target space vehicle. Missions often grant elevated access to vendors in order to allow them to manage internal systems as well as cloud-based environments. The vendor's access may be intended to be limited to the infrastructure being maintained but it may provide laterally movement into the target space vehicle. Attackers may leverage security weaknesses in the vendor environment to gain access to more critical mission resources or network locations. In the space vehicle context vendors may have direct commanding and updating capabilities outside of the primary communication channel. |
|
IA-0009.03 |
User Segment |
Threat actors can target the user segment in an effort to laterally move into other areas of the end-to-end mission architecture. When user segments are interconnected, threat actors can exploit lack of segmentation as the user segment's security undoubtedly varies in their system security posture and attack surface than the primary space mission. The user equipment and users themselves provide ample attack surface as the human element and their vulnerabilities (i.e., social engineering, phishing, iOT) are often the weakest security link and entry point into many systems. |
| IA-0011 |
Auxiliary Device Compromise |
Threat actors may exploit the auxiliary/peripheral devices that get plugged into space vehicles. It is no longer atypical to see space vehicles, especially CubeSats, with Universal Serial Bus (USB) ports or other ports where auxiliary/peripheral devices can be plugged in. Threat actors can execute malicious code on the space vehicles by copying the malicious code to auxiliary/peripheral devices and taking advantage of logic on the space vehicle to execute code on these devices. This may occur through manual manipulation of the auxiliary/peripheral devices, modification of standard IT systems used to initially format/create the auxiliary/peripheral device, or modification to the auxiliary/peripheral devices' firmware itself. |
| IA-0012 |
Assembly, Test, and Launch Operation Compromise |
Threat actors may target the spacecraft hardware and/or software while the spacecraft is at Assembly, Test, and Launch Operation (ATLO). ATLO is often the first time pieces of the spacecraft are fully integrated and exchanging data across interfaces. Malware could propagate from infected devices across the integrated spacecraft. For example, test equipment (i.e., transient cyber asset) is often brought in for testing elements of the spacecraft. Additionally, varying levels of physical security is in place which may be a reduction in physical security typically seen during development. The ATLO environment should be considered a viable attack vector and the appropriate/equivalent security controls from the primary development environment should be implemented during ATLO as well. |
| EX-0005 |
Exploit Hardware/Firmware Corruption |
Threat actors can target the underlying hardware and/or firmware using various TTPs that will be dependent on the specific hardware/firmware. Typically, software tools (e.g., antivirus, antimalware, intrusion detection) can protect a system from threat actors attempting to take advantage of those vulnerabilities to inject malicious code. However, there exist security gaps that cannot be closed by the above-mentioned software tools since they are not stationed on software applications, drivers or the operating system but rather on the hardware itself. Hardware components, like memory modules and caches, can be exploited under specific circumstances thus enabling backdoor access to potential threat actors. In addition to hardware, the firmware itself which often is thought to be software in its own right also provides an attack surface for threat actors. Firmware is programming that's written to a hardware device's non-volatile memory where the content is saved when a hardware device is turned off or loses its external power source. Firmware is written directly onto a piece of hardware during manufacturing and it is used to run on the device and can be thought of as the software that enables hardware to run. In the space vehicle context, firmware and field programmable gate array (FPGA)/application-specific integrated circuit (ASIC) logic/code is considered equivalent to firmware. |
|
EX-0005.01 |
Design Flaws |
Threat actors may target design features/flaws with the hardware design to their advantage to cause the desired impact. Threat actors may utilize the inherent design of the hardware (e.g. hardware timers, hardware interrupts, memory cells), which is intended to provide reliability, to their advantage to degrade other aspects like availability. Additionally, field programmable gate array (FPGA)/application-specific integrated circuit (ASIC) logic can be exploited just like software code can be exploited. There could be logic/design flaws embedded in the hardware (i.e., FPGA/ASIC) which may be exploitable by a threat actor. |
| 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-0009.02 |
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. |
| 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-0002.01 |
Hardware |
Threat actors may find and target various hardware backdoors within the victim spacecraft in the hopes of maintaining their attack. Once in orbit, mitigating the risk of various hardware backdoors becomes increasingly difficult for ground controllers. By targeting these specific vulnerabilities, threat actors are more likely to remain persistent on the victim spacecraft and perpetuate further attacks. |
| PER-0003 |
Ground System Presence |
Threat actors may compromise target owned ground systems that can be used for persistent access to the spacecraft or to perpetuate other techniques. These ground systems have already been configured for communications to the victim spacecraft. By compromising this infrastructure, threat actors can stage, launch, and execute persistently. |
| 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. |
| DE-0004 |
Masquerading |
Threat actors may gain access to a victim spacecraft by masquerading as an authorized entity. This can be done several ways, including through the manipulation of command headers, spoofing locations, or even leveraging Insider's access (i.e., Insider Threat) |
| LM-0001 |
Hosted Payload |
Threat actors may use the hosted payload within the victim spacecraft in order to gain access to other subsystems. The hosted payload often has a need to gather and send data to the internal subsystems, depending on its purpose. Threat actors may be able to take advantage of this communication in order to laterally move to the other subsystems and have commands be processed. |
| EXF-0006 |
Modify Communications Configuration |
Threat actors can manipulate communications equipment, modifying the existing software, hardware, or the transponder configuration to exfiltrate data via unintentional channels the mission has no control over. |
|
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. |
|
EXF-0006.02 |
Transponder |
Threat actors may change the transponder configuration to exfiltrate data via radio access to an attacker-controlled asset. |
| EXF-0007 |
Compromised Ground System |
Threat actors may compromise target owned ground systems that can be used for future campaigns or to perpetuate other techniques. These ground systems have already been configured for communications to the victim spacecraft. By compromising this infrastructure, threat actors can stage, launch, and execute an operation. Threat actors may utilize these systems for various tasks, including Execution and Exfiltration. |
| EXF-0008 |
Compromised Developer Site |
Threat actors may compromise development environments located within the ground system or a developer/partner site. This attack can take place in a number of different ways, including manipulation of source code, manipulating environment variables, or replacing compiled versions with a malicious one. This technique is usually performed before the target spacecraft is in orbit, with the hopes of adding malicious code to the actual FSW during the development process. |
| EXF-0009 |
Compromised Partner Site |
Threat actors may compromise access to partner sites that can be used for future campaigns or to perpetuate other techniques. These sites are typically configured for communications to the primary ground station(s) or in some cases the spacecraft itself. Unlike mission operated ground systems, partner sites may provide an easier target for threat actors depending on the company, roles and responsibilities, and interests of the third-party. By compromising this infrastructure, threat actors can stage, launch, and execute an operation. Threat actors may utilize these systems for various tasks, including Execution and Exfiltration. |
