What happened
Microsoft describes a large-scale npm supply-chain campaign (dubbed “Miasma”) that compromised over 90 versions of @redhat-cloud-services packages to silently infect CI/CD and developer environments. The malicious packages perform preinstall persistence, steal credentials from GitHub, cloud platforms, and local machines, and propagate like a worm by republishing trusted packages. The report includes observed tradecraft, detection opportunities, and mitigation guidance to remediate impacted packages and reduce risk to build pipelines and cloud identities.
