Miasma worm shapeshifts, but cloud secret-scouting remains the goal

A large-scale npm supply chain attack compromised over 90 versions of @redhat-cloud-services packages, silently infecting CI/CD environments and developer systems. The malicious code steals credentials from GitHub, cloud platforms, and local machines, then spreads like a worm by republishing trusted packages. Discover how the attack works, what data is at risk, and the steps you can take to protect your organization. The post Preinstall to persistence: Inside the Red Hat npm Miasma credential-stealing campaign appeared first on Microsoft Security Blog.

Two more GitHub Actions workflows have become the latest to be compromised by credential-stealing malware by a threat actor known as TeamPCP, the cloud-native cybercriminal operation also behind the Trivy supply chain attack
