Description
A new supply chain attack targeting Trivy has compromised 75 out of 76 version tags in the aquasecurity/trivy-action GitHub repository. The attacker force-pushed these tags to serve malicious payloads, effectively turning trusted version references into a distribution mechanism for an infostealer. The malicious code executes within GitHub Actions runners, targeting sensitive data in CI/CD environments. It harvests secrets from runner process memory and the filesystem, encrypts the collected data, and exfiltrates it to an attacker-controlled endpoint or a fallback GitHub-based channel. The attack's scope is significant, potentially affecting over 10,000 workflow files on GitHub referencing this action.
