An attacker replaces legitimate hardware in the system with faulty counterfeit or tampered hardware in the supply chain distribution channel, with purpose of causing malicious disruption or allowing for additional compromise when the system is deployed.
Likelihood Of Attack
The table below shows the other attack patterns and high level categories that are related to this attack pattern. These relationships are defined as ChildOf and ParentOf, and give insight to similar items that may exist at higher and lower levels of abstraction. In addition, relationships such as CanFollow, PeerOf, and CanAlsoBe are defined to show similar attack patterns that the user may want to explore.
Meta Attack Pattern - A meta level attack pattern in CAPEC is a decidedly abstract characterization of a specific methodology or technique used in an attack. A meta attack pattern is often void of a specific technology or implementation and is meant to provide an understanding of a high level approach. A meta level attack pattern is a generalization of related group of standard level attack patterns. Meta level attack patterns are particularly useful for architecture and design level threat modeling exercises.
Physical access to the system after it has left the manufacturer but before it is deployed at the victim location.
Advanced knowledge of the design of the system.
Hardware creation and manufacture of replacement components.
During shipment the attacker is able to intercept a system that has been purchased by the victim, and replaces a math processor card that functions just like the original, but contains advanced malicious capability. Once deployed, the system functions as normal, but allows for the attacker to remotely communicate with the system and use it as a conduit for additional compromise within the victim's environment.
