Threats include dependency confusion, compromise of an upstream providers infrastructure, theft of code signing certificates, and CI/CD system exploits. More broadly, threats may be grouped into four categories based upon what component of the supply chain they seek to compromise [4,5]\n\nSource code threats. These type of threats focus on violating the integrity of a source code which is then built and and deployed or potentially consumed by other software projects. Threats in this category include VCS exploits, the introduction of malicious or vulnerable code into a codebase, or building code from an unauthorized branch. Build environment threats. These threats modify a software artifact but without altering the underlying source code or exploiting the build process itself. Examples include build cache poisoning, compromising a privileged account used by the build tool, or publishing software built from an untrusted source. Dependency related threats. Threats that result from the consumption of both direct and transitive software dependencies. The most common threat is using a vulnerable or compromised dependency. Deployment and runtime threats. These threats exploit either the deployment process or runtime environment. Common examples include compromising a privilege CI/CD account, software misconfigurations, and deployment of compromised binaries.\n\nThe characteristics of threat actors seeking to exploit the SSC are similarly diverse. Although SSC compromise is often associated with highly sophisticated threat actors, such sophistication is not inherently necessary for attacking the SSC, especially if the attack focuses on compromising the SSC of entities with poor security practices. Threat actor motive also varies widely. A SSC exploit can result in loss of confidentiality, integrity, and/or availability of any organization's assets and thus fulfill a wide range of attacker goals such as espionage or financial gain. …\n\nAttribution: Adapted from OWASP Cheat Sheet Series under CC-BY-SA-4.0.
