GHOSTACTION ATTACK STEALS 3,325 SECRETS FROM GITHUB PROJECTS
Summary from the TLDR InfoSec newsletter
The GhostAction supply chain attack compromised 817 GitHub repositories by injecting malicious workflow files that appeared to be routine automation scripts but actually exfiltrated CI/CD secrets to an external server. The campaign affected 327 developers across multiple programming languages, stealing 3,325 secrets, including npm, PyPI, DockerHub tokens, and AWS credentials that could enable further attacks on software supply chains. The attackers personalized each commit and analyzed legitimate workflows to identify which secrets to target. At least 24 projects (9 npm and 15 PyPI) remain at risk from compromised tokens despite no confirmed malicious package releases yet.
