Threat actors may compromise a 3rd-party spacecraft that has the capability to maneuver within close proximity to a target spacecraft. This technique enables historically lower-tier attackers the same capability as top tier nation-state actors without the initial development cost. Additionally, this technique complicates attribution of an attack. Since many of the commercial and military assets in space are tracked, and that information is publicly available, attackers can identify the location of space assets to infer the best positioning for intersecting orbits. Proximity operations support avoidance of the larger attenuation that would otherwise affect the signal when propagating long distances, or environmental circumstances that may present interference. Further, the compromised spacecraft may posses the capability to grapple target spacecraft once it has established the appropriate space rendezvous. If from a proximity / rendezvous perspective a threat actor has the ability to connect via docking interface or expose testing (i.e., JTAG port) once it has grappled the target spacecraft, they could perform various attacks depending on the access enabled via the physical connection.

|CM0009||Threat Intelligence Program||A threat intelligence program helps an organization generate their own threat intelligence information and track trends to inform defensive priorities and mitigate risk. Leverage all-source intelligence services or commercial satellite imagery to identify and track adversary infrastructure development/acquisition. Countermeasures for this attack fall outside the scope of the mission in the majority of cases.||PM-16 PM-16(1) PM-16(1) RA-10 RA-3 RA-3(2) RA-3(3) SA-3 SA-8 SR-8||D3-PH D3-AH D3-NM D3-NVA D3-SYSM D3-SYSVA||A.5.7 A.5.7 6.1.2 8.2 9.3.2 A.8.8 A.5.7 A.5.2 A.5.8 A.8.25 A.8.31 A.8.27 A.8.28|
|CM0077||Space Domain Awareness||The credibility and effectiveness of many other types of defenses are enabled or enhanced by the ability to quickly detect, characterize, and attribute attacks against space systems. Space domain awareness (SDA) includes identifying and tracking space objects, predicting where objects will be in the future, monitoring the space environment and space weather, and characterizing the capabilities of space objects and how they are being used. Exquisite SDA—information that is more timely, precise, and comprehensive than what is publicly available—can help distinguish between accidental and intentional actions in space. SDA systems include terrestrial-based optical, infrared, and radar systems as well as space-based sensors, such as the U.S. military’s Geosynchronous Space Situational Awareness Program (GSSAP) inspector satellites. Many nations have SDA systems with various levels of capability, and an increasing number of private companies (and amateur space trackers) are developing their own space surveillance systems, making the space environment more transparent to all users.* *https://csis-website-prod.s3.amazonaws.com/s3fs-public/publication/210225_Harrison_Defense_Space.pdf?N2KWelzCz3hE3AaUUptSGMprDtBlBSQG||CP-13 CP-2(3) CP-2(4) CP-2(5) CP-2(7) PE-20 PE-6 SI-4(17)||D3-APLM D3-PM D3-HCI D3-SYSM||A.5.29 A.7.4 A.8.16 A.5.10|
