10 Layers Deep: How StepSecurity Stops TeamPCP's Trivy Supply Chain Attack on GitHub Actions

TeamPCP compromised 76 Trivy version tags overnight in a supply chain attack targeting GitHub Actions workflows. A similar attack called KICS followed the same playbook shortly after. The attacks aimed at credential exfiltration by injecting malicious code into widely-used GitHub Actions. StepSecurity details how their platform's ten independent security layers work together to detect and prevent such attacks. The article covers runtime detection of compromised actions, blocking credential exfiltration, and incident response across organizations. The campaign highlights the growing threat of supply chain attacks targeting CI/CD pipelines. One security control alone is insufficient to stop sophisticated multi-stage supply chain attacks.
