GhostAction surge targets thousands of GitHub repos
🛡️ Since October 8–9, 2026, a renewed GhostAction campaign compromised roughly 1,900 GitHub accounts and targeted over 30,000 repositories, attempting to extract thousands of CI/CD secrets. Security firm GitGuardian observed the activity and noted evolving payloads that scan git history for AWS keys, tokens, and AI API keys. GitHub began blocking the malicious workflows on October 9, limiting later waves.
