CAPEC-674 Design for FPGA Maliciously Altered

CAPEC-674 Metadata

Likelihood of Attack

Low

Typical Severity

High

Overview

Summary

An adversary alters the functionality of a field-programmable gate array (FPGA) by causing an FPGA configuration memory chip reload in order to introduce a malicious function that could result in the FPGA performing or enabling malicious functions on a host system. Prior to the memory chip reload, the adversary alters the program for the FPGA by adding a function to impact system operation.

Prerequisites

An adversary would need to have access to FPGA programming/configuration-related systems in a chip maker’s development environment where FPGAs can be initially configured prior to delivery to a customer or have access to such systems in a customer facility where end-user FPGA configuration/reconfiguration can be performed.

Potential Solutions / 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 including for FPGA programming and program uploads to FPGA chips. Require that provenance of COTS microelectronic components be known whenever procured. Conduct detailed vendor assessment before acquiring COTS hardware.

CAPEC ID	Description
CAPEC-447	An adversary modifies the design of a technology, product, or component to acheive a negative impact once the system is deployed. In this type of attack, the goal of the adversary is to modify the design of the system, prior to development starting, in such a way that the negative impact can be leveraged when the system is later deployed. Design alteration attacks differ from development alteration attacks in that design alteration attacks take place prior to development and which then may or may not be developed by the adverary. Design alteration attacks include modifying system designs to degrade system performance, cause unexpected states or errors, and general design changes that may lead to additional vulnerabilities. These attacks generally require insider access to modify design documents, but they may also be spoofed via web communications. The product is then developed and delivered to the user where the negative impact can be leveraged at a later time.
