DARPA wants to create ‘self-healing’ firmware that can respond and recover from cyberattacks 

**Executive summary:** DARPA's Red-C initiative proposes reengineering firmware on bus-based systems (notably PCIe and CXL) to create distributed, embedded forensic sensors that detect compromises, coordinate responses across components, and enable live restoration and patching to reduce impact from attacks like ransomware; the article highlights potential resilience benefits, especially for resource-limited organizations, while also outlining significant technical, security, and industry-adoption challenges.
