Malware is inserted in a server motherboard (e.g., in the flash memory) in order to alter server functionality from that intended. The development environment or hardware/software support activity environment is susceptible to an adversary inserting malicious software into hardware components during development or update.
Likelihood Of Attack
This table 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.
Standard Attack Pattern - A standard level attack pattern in CAPEC is focused on a specific methodology or technique used in an attack. It is often seen as a singular piece of a fully executed attack. A standard attack pattern is meant to provide sufficient details to understand the specific technique and how it attempts to accomplish a desired goal. A standard level attack pattern is a specific type of a more abstract meta level attack pattern.
An adversary with access to hardware/software processes and tools within the development or hardware/software support environment can insert malicious software into hardware components during development or update/maintenance.
This table specifies different individual consequences associated with the attack pattern. The Scope identifies the security property that is violated, while the Impact describes the negative technical impact that arises if an adversary succeeds in their attack. The Likelihood provides information about how likely the specific consequence is expected to be seen relative to the other consequences in the list. For example, there may be high likelihood that a pattern will be used to achieve a certain impact, but a low likelihood that it will be exploited to achieve a different impact.
Execute Unauthorized Commands
Purchase IT systems, components and parts from government approved vendors whenever possible.
Establish diversity among suppliers.
Conduct rigorous threat assessments of suppliers.
Require that Bills of Material (BoM) for critical parts and components be certified.
Utilize contract language requiring contractors and subcontractors to flow down to subcontractors and suppliers SCRM and SCRA (Supply Chain Risk Assessment) requirements.
Establish trusted supplier networks.
Malware is inserted into the Unified Extensible Firmware Interface (UEFI) software that resides on a flash memory chip soldered to a computer’s motherboard. It is the first thing to turn on when a system is booted and is allowed access to almost every part of the operating system. Hence, the malware will have extensive control over operating system functions and persist after system reboots. [REF-685]
