CAPEC-672: Malicious Code Implanted During Chip Programming

Description
<p>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.<p>
Extended Description

This attack first requires the adversary to trick the victim into installing a Trojan Horse application on their system, such as a malicious web browser plugin, which the adversary then leverages to mount the attack. The victim interacts with a web application, such as a banking website, in a normal manner and under the assumption that the connection is secure. However, the adversary can now alter and/or reroute traffic between the client application (e.g., web browser) and the coinciding endpoint, while simultaneously displaying intended transactions and data back to the user. The adversary may also be able to glean cookies, HTTP sessions, and SSL client certificates, which can be used to pivot into an authenticated intranet. Identifying AITB is often difficult because these attacks are successful even when security mechanisms such as SSL/PKI and multifactor authentication are present, since they still function as intended during the attack.

Prerequisites

This table shows the other attack patterns and high level categories that are related to this attack pattern.

  • An adversary would need to have access to a foundry’s or chip maker’s development/production environment where programs for specific chips are developed, managed and uploaded into targeted chips prior to distribution or sale.
Skills required

This table shows the other attack patterns and high level categories that are related to this attack pattern.

  • Medium An adversary needs to be skilled in microprogramming, manipulation of configuration management systems, and in the operation of tools used for the uploading of programs into chips during manufacture. Uploading can be for individual chips or performed on a large scale basis.
