GhostAction
GhostAction is a large-scale software supply chain attack on GitHub. According to the provided reporting, it was discovered after suspicious activity in the FastUUID project on September 2. The attackers compromised maintainer accounts and injected a malicious GitHub Actions workflow to harvest and exfiltrate secrets from repositories. The campaign exposed more than 3,300 secrets, including PyPI, npm, DockerHub, GitHub tokens, Cloudflare API keys, AWS access keys, and database credentials. Researchers identified at least 817 repositories with similar malicious commits, all exfiltrating data to the same endpoint, and reported impacts across at least nine npm packages and 15 PyPI packages. By September 5, researchers had notified GitHub, npm, and PyPI and filed issues across 573 impacted repositories. The content also notes that researchers believe GhostAction is separate from the earlier s1ngularity GitHub account attack. No specific threat actor attribution is provided in the content.
