Deception and Decoys

Deception can be used to conceal or mislead others on the “location, capability, operational status, mission type, and/or robustness” of a satellite. Public messaging, such as launch announcements, can limit information or actively spread disinformation about the capabilities of a satellite, and satellites can be operated in ways that conceal some of their capabilities. Another form of deception could be changing the capabilities or payloads on satellites while in orbit. Satellites with swappable payload modules could have on-orbit servicing vehicles that periodically move payloads from one satellite to another, further complicating the targeting calculus for an adversary because they may not be sure which type of payload is currently on which satellite. Satellites can also use tactical decoys to confuse the sensors on ASAT weapons and SDA systems. A satellite decoy can consist of an inflatable device designed to mimic the size and radar signature of a satellite, and multiple decoys can be stored on the satellite for deployment when needed. Electromagnetic decoys can also be used in space that mimic the RF signature of a satellite, similar to aircraft that use airborne decoys, such as the ADM-160 Miniature Air-launched Decoy (MALD).

Techniques Addressed by Countermeasure

ID Name Description
REC-0007 Monitor for Safe-Mode Indicators Threat actors may gather information regarding safe-mode indicators on the victim spacecraft. Safe-mode is when all non-essential systems are shut down and only essential functions within the spacecraft are active. During this mode, several commands are available to be processed that are not normally processed. Further, many protections may be disabled at this time.
REC-0009 Gather Mission Information Threat actors may initially seek to gain an understanding of a target mission by gathering information commonly captured in a Concept of Operations (or similar) document and related artifacts. Information of interest includes, but is not limited to: - the needs, goals, and objectives of the system - system overview and key elements/instruments - modes of operations (including operational constraints) - proposed capabilities and the underlying science/technology used to provide capabilities (i.e., scientific papers, research studies, etc.) - physical and support environments
IA-0005 Rendezvous & Proximity Operations Threat actors may perform a space rendezvous which is a set of orbital maneuvers during which a spacecraft arrives at the same orbit and approach to a very close distance (e.g. within visual contact or close proximity) to a target spacecraft.
.02 Docked Vehicle / OSAM Threat actors may leverage docking vehicles to laterally move into a target spacecraft. If information is known on docking plans, a threat actor may target vehicles on the ground or in space to deploy malware to laterally move or execute malware on the target spacecraft via the docking interface.
.03 Proximity Grappling Threat actors 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.
IA-0010 Exploit Reduced Protections During Safe-Mode Threat actors may take advantage of the victim spacecraft being in safe mode and send malicious commands that may not otherwise be processed. Safe-mode is when all non-essential systems are shut down and only essential functions within the spacecraft are active. During this mode, several commands are available to be processed that are not normally processed. Further, many protections may be disabled at this time.
EX-0011 Exploit Reduced Protections During Safe-Mode Threat actors may take advantage of the victim spacecraft being in safe mode and send malicious commands that may not otherwise be processed. Safe-mode is when all non-essential systems are shut down and only essential functions within the spacecraft are active. During this mode, several commands are available to be processed that are not normally processed. Further, many protections may be disabled at this time.
EX-0017 Kinetic Physical Attack Kinetic physical attacks attempt to damage or destroy space- or land-based space assets. They typically are organized into three categories: direct-ascent, co-orbital, and ground station attacks [beyond the focus of SPARTA at this time]. The nature of these attacks makes them easier to attribute and allow for better confirmation of success on the part of the attacker.* *https://aerospace.csis.org/aerospace101/counterspace-weapons-101
.01 Direct Ascent ASAT A direct-ascent ASAT is often the most commonly thought of threat to space assets. It typically involves a medium- or long-range missile launching from the Earth to damage or destroy a satellite in orbit. This form of attack is often easily attributed due to the missile launch which can be easily detected. Due to the physical nature of the attacks, they are irreversible and provide the attacker with near real-time confirmation of success. Direct-ascent ASATs create orbital debris which can be harmful to other objects in orbit. Lower altitudes allow for more debris to burn up in the atmosphere, while attacks at higher altitudes result in more debris remaining in orbit, potentially damaging other spacecraft in orbit.* *https://aerospace.csis.org/aerospace101/counterspace-weapons-101
.02 Co-Orbital ASAT Co-orbital ASAT attacks are when another satellite in orbit is used to attack. The attacking satellite is first placed into orbit, then later maneuvered into an intercepting orbit. This form of attack requires a sophisticated on-board guidance system to successfully steer into the path of another satellite. A co-orbital attack can be a simple space mine with a small explosive that follows the orbital path of the targeted satellite and detonates when within range. Another co-orbital attack strategy is using a kinetic-kill vehicle (KKV), which is any object that can be collided into a target satellite.* *https://aerospace.csis.org/aerospace101/counterspace-weapons-101
EX-0018 Non-Kinetic Physical Attack A non-kinetic physical attack is when a satellite is physically damaged without any direct contact. Non-kinetic physical attacks can be characterized into a few types: electromagnetic pulses, high-powered lasers, and high-powered microwaves. These attacks have medium possible attribution levels and often provide little evidence of success to the attacker.* *https://aerospace.csis.org/aerospace101/counterspace-weapons-101
.01 Electromagnetic Pulse (EMP) An EMP, such as those caused by high-altitude detonation of certain bombs, is an indiscriminate form of attack in space. For example, a nuclear detonation in space releases an electromagnetic pulse (EMP) that would have near immediate consequences for the satellites within range. The detonation also creates a high radiation environment that accelerates the degradation of satellite components in the affected orbits.* *https://aerospace.csis.org/aerospace101/counterspace-weapons-101
.02 High-Powered Laser A high-powered laser can be used to permanently or temporarily damage critical satellite components (i.e. solar arrays or optical centers). If directed toward a satellite’s optical center, the attack is known as blinding or dazzling. Blinding, as the name suggests, causes permanent damage to the optics of a satellite. Dazzling causes temporary loss of sight for the satellite. While there is clear attribution of the location of the laser at the time of the attack, the lasers used in these attacks may be mobile, which can make attribution to a specific actor more difficult because the attacker does not have to be in their own nation, or even continent, to conduct such an attack. Only the satellite operator will know if the attack is successful, meaning the attacker has limited confirmation of success, as an attacked nation may not choose to announce that their satellite has been attacked or left vulnerable for strategic reasons. A high-powered laser attack can also leave the targeted satellite disabled and uncontrollable, which could lead to collateral damage if the satellite begins to drift. A higher-powered laser may permanently damage a satellite by overheating its parts. The parts most susceptible to this are satellite structures, thermal control panels, and solar panels.* *https://aerospace.csis.org/aerospace101/counterspace-weapons-101
.03 High-Powered Microwave High-powered microwave (HPM) weapons can be used to disrupt or destroy a satellite’s electronics. A “front-door” HPM attack uses a satellite’s own antennas as an entry path, while a “back-door” attack attempts to enter through small seams or gaps around electrical connections and shielding. A front-door attack is more straightforward to carry out, provided the HPM is positioned within the field of view of the antenna that it is using as a pathway, but it can be thwarted if the satellite uses circuits designed to detect and block surges of energy entering through the antenna. In contrast, a back-door attack is more challenging, because it must exploit design or manufacturing flaws, but it can be conducted from many angles relative to the satellite. Both types of attacks can be either reversible or irreversible; however, the attacker may not be able to control the severity of the damage from the attack. Both front-door and back-door HPM attacks can be difficult to attribute to an attacker, and like a laser weapon, the attacker may not know if the attack has been successful. A HPM attack may leave the target satellite disabled and uncontrollable which can cause it to drift into other satellites, creating further collateral damage.* *https://aerospace.csis.org/aerospace101/counterspace-weapons-101
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.
.01 Debris Field Threat actors may hide their spacecraft by laying dormant within clusters of space junk or similar debris fields. This could serve several purposes including concealment of inspection activities being performed by the craft, as well as facilitating some future kinetic intercept/attack, and more.
