CAPEC-674: Design for FPGA Maliciously Altered
Description
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.
- Likelihood of attack
- Low
- Typical severity
- High
- Abstraction
- DetailedA low-level, detailed pattern, often for a particular technology.
Mechanism of attack: Manipulate System Resources
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.
Skills required
- HighAn adversary would need to be skilled in FPGA programming in order to create/manipulate configurations in such a way that when loaded into an FPGA, the end user would be able to observe through testing all user-defined required functions but would be unaware of any additional functions the adversary may have introduced.
Consequences
- Integrity
Alter Execution Logic
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.
