On June 1, 2026, we detected multiple official packages from the @redhat-cloud-services scope on npm were compromised with a credential-stealing worm. In total, 96 versions across 32 packages have been compromised, cumulatively downloaded 116,991 times per week. The malware appears similar to the Mini Shai-Hulud malware that was recently open-sourced by TeamPCP. Since the tooling was made publicly available, other threat actors now have access to the same techniques and can replicate or adapt them. The packages were published via GitHub Actions OIDC, indicating the CI/CD pipeline was compromised rather than an npm token. 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.
@redhat-cloud-services npm packages compromised with Miasma, a new variant of Mini Shai-Hulud.The payload embedded across the affected packages has strong resemblances to Mini Shai-Hulud, the supply chain malware open-sourced by TeamPCP. Interestingly, this version calls itself "Miasma" and appears to have replaced the familiar Dune references of Shai-Hulud with Greek mythology.
TeamPCP is a threat actor group that has been running targeted CI/CD supply chain attacks for several months. Their Mini Shai-Hulud malware is a sophisticated credential-stealing worm that spreads by republishing backdoored versions of packages the victim account has access to. We have previously reported on compromises affecting Mistral and TanStack, Microsoft's Durable Task, PyTorch Lightning, Bitwarden CLI, and Intercom, all traced back to the same tooling.
When TeamPCP open-sourced Mini Shai-Hulud, the threat expanded beyond a single actor. Any group can now pick up the framework, adapt it, and deploy it against new targets.
Trusted publishing is a mechanism npm introduced to eliminate long-lived publish tokens from CI/CD pipelines, replacing them with short-lived OIDC tokens issued by GitHub Actions. It was designed to be more secure, but as recent attacks show, it can be bypassed if an attacker gains access to a CI/CD pipeline through a vulnerability or compromised token.
We found a Red Hat employee's GitHub account was compromised and used to push malicious orphan commits directly to several repositories, bypassing code review entirely. Those orphan commits contained a workflow file (ci.yaml) and a script (_index.js).

WORKFLOW_ID: "ci.yaml"
REPO_ID_SUFFIX: "RedHatInsights/frontend-components"When the workflow runs, it installs Bun and executes _index.js, passing it a list of target packages via the OIDC_PACKAGES environment variable. The script uses the id-token: write permission to request a short-lived OIDC token from GitHub, then uses that token to authenticate directly with npm's trusted publishing endpoint and publish backdoored versions of every package in the list.
This is the same fundamental pattern seen in the TanStack and Bitwarden compromises: the CI/CD pipeline itself becomes the attack surface, while OIDC-based trusted publishing - designed to eliminate long-lived tokens - becomes a misleading trust signal.
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.
"scripts": {
"preinstall": "node index.js"
}
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.
If you are an Aikido user, check your central feed and filter on malware issues. This will surface as a 100/100 critical issue. Aikido rescans nightly, but we recommend triggering a manual rescan now.
If you are not yet an Aikido user, you can create an account and connect your repos. Our malware coverage is included in the free plan, no credit card required.
For broader coverage across your whole team, Aikido's Device Protection gives you visibility and control over the software packages installed on your team's devices. It covers browser extensions, code libraries, IDE plugins, and build dependencies, all in one place. Stop malware before it gets installed.
For future protection, consider Aikido Safe Chain (open source). Safe Chain sits in your existing workflow, intercepting npm, npx, yarn, pnpm, and pnpx commands and checking packages against Aikido Intel before install.
If you have installed any of the following package versions, treat all CI secrets, cloud credentials, SSH keys, and npm tokens as compromised and rotate them immediately:
