This solution brief explores the primary causes behind the rise in firmware supply chain attacks, highlighting the complexity and interconnected nature of modern supply chains. As detailed across pages 3–6, contributing factors include unsecured supply chain channels, insufficient security controls, lack of transparency, inadequate testing procedures, use of counterfeit components, insider threats, and weak development practices. The document emphasizes that a single weak link can compromise an entire supply chain, enabling attackers to inject malicious firmware or exploit vulnerabilities. By understanding these risks, organizations can strengthen security controls, improve visibility, and implement better testing and validation processes to reduce exposure to increasingly sophisticated su
