Miasma supply-chain attack compromises Red Hat npm packages and targets developer/cloud credentials

Hackers published 96 malicious package versions, injected with a credential-stealing worm similar to Mini Shai-Hulud. The post Supply Chain Attack Hits 32 Red Hat NPM Packages appeared first on SecurityWeek.

Unknown attackers have compromised 30+ Red Hat Cloud Services npm packages with malware that goes after credentials stored in developers’ build environment. What the malware stole and how it can spread further The compromised packages were published in two different GitHub source repositories on June 1, 2026, between 10:53 and 10:53:33 UTC and 13:44 and 13:46:47 UTC. According to Wiz Security, a specific Red Hat employee GitHub account was compromised and “pushed malicious orphan commits … More → The post Red Hat npm packages compromised in new Mini Shai-Hulud malware wave appeared first on Help Net Security.

More than 30 npm packages under Red Hat's '@redhat-cloud-services' namespace were compromised in a supply-chain attack that distributed a new variant of the Shai-Hulud credential-stealing malware, dubbed "Miasma." [...]

A new Mini Shai-Hulud supply chain attack campaign, codenamed Miasma, has compromised @redhat-cloud-services packages to steal credentials and secrets from developer machines and deliver a self-propagating worm. "This is effectively a Mini Shai-Hulud campaign: it uses the same core tactics of install-time execution, credential harvesting, CI/CD targeting, encrypted exfiltration, and potential

Aikido Security says more than 30 official @redhat-cloud-services npm packages were compromised with a credential-stealing worm called "Miasma," a variant resembling the open-sourced Mini Shai-Hulud supply-chain malware. "The packages were published via GitHub Actions OIDC, indicating the CI/CD pipeline was compromised rather than an npm token," the report says. "If you have installed any affected package versions since June 1, 2026, treat all CI secrets, cloud credentials, SSH keys, and npm tokens as compromised and rotate them immediately." From the report: Each compromised package declares a preinstall script in its package.json that executes node index.js automatically on every npm install, before any application code runs and before the developer has any indication something is wrong. The index.js file is 4.2 MB payload hidden behind multiple layers of obfuscation. As with previous Mini Shai-Hulud attacks, the payload performs a broad credential sweep across cloud providers, CI/CD environments, and developer tooling. On the CI side it targets GitHub Actions secrets including GITHUB_TOKEN and ACTIONS_RUNTIME_TOKEN. For cloud credentials it collects AWS access keys and session tokens, GCP application default credentials and service account key files, and Azure service principal credentials and managed identity tokens. It also sweeps for HashiCorp Vault tokens, Kubernetes service account tokens and kubeconfig files, npm and PyPI publish tokens, SSH private keys, Docker registry credentials, GPG keys, and any .env files it can find across the filesystem.
