What Is Dependency Confusion?

Dependency confusion occurs when a software build or package-management system retrieves an attacker-controlled public package instead of the organization’s intended internal dependency. Certification exams may describe identical package names in private and public repositories and ask candidates to identify the software supply-chain risk. An attacker may publish a package with the expected internal name and a version number that causes automated tools to select it during installation or compilation. Defenses include private package namespaces, repository-priority controls, package allowlists, dependency locking, integrity verification, and continuous monitoring of build activity. Development teams should also document approved sources and prevent build systems from contacting untrusted repositories. If suspicious code appears, investigators should preserve build logs, identify affected versions, remove the package, rotate exposed secrets, and rebuild trusted artifacts.
