CAPEC-672: Malicious Code Implanted During Chip Programming
During the programming step of chip manufacture, an adversary with access and necessary technical skills maliciously alters a chip’s intended program logic to produce an effect intended by the adversary when the fully manufactured chip is deployed and in operational use. Intended effects can include the ability of the adversary to remotely control a host system to carry out malicious acts.

Mitigations
Utilize DMEA’s (Defense Microelectronics Activity) Trusted Foundry Program members for acquisition of microelectronic components.
Ensure that each supplier performing hardware development implements comprehensive, security-focused configuration management of microcode and microcode generating tools and software.
Require that provenance of COTS microelectronic components be known whenever procured.
Conduct detailed vendor assessment before acquiring COTS hardware.
