90% of modern application code comes from open source. The Log4j incident (2021) affected millions of systems worldwide and is the most severe supply chain attack in history. The SolarWinds incident has affected US government agencies.
Common risks
Dependency obfuscation: Attackers publish packages with the same name to public repositories. Poison package: The maintainer's account has been hacked and malicious code has been implanted. Unmaintained dependency: Abandoned package is no longer updated, and the vulnerability has not been fixed.
Protective tools
SCA software component analysis: Snyk, Dependabot, OWASP Dependency Check. SBOM software bill of materials: CycloneDX, SPDX format, listing all dependencies.
best practices
Minimum dependency principle, version locking, periodic dependency auditing, use of private repositories, hash locking, monitoring security announcements.
