Mitigation

Phase: Testing

Description:

  • Implement a rigorous testing strategy that incorporates randomization to explore instruction sequences that are unlikely to appear in normal workloads in order to identify halt and catch fire instruction sequences.
Mitigation

Phase: Patching and Maintenance

Description:

  • Patch operating system to avoid running Halt and Catch Fire type sequences or to mitigate the damage caused by unexpected behavior. See [REF-1108].
CAPEC-212: Functionality Misuse

An adversary leverages a legitimate capability of an application in such a way as to achieve a negative technical impact. The system functionality is not altered or modified but used in a way that was not intended. This is often accomplished through the overuse of a specific functionality or by leveraging functionality with design flaws that enables the adversary to gain access to unauthorized, sensitive data.
