Malicious code in @redhat-cloud-services/javascript-clients-shared (npm)
Part of the "Mini Shai-Hulud" supply chain worm campaign that compromised the GitHub Actions OIDC trusted publisher shared by Red Hat Cloud Services npm packages. The attacker injected a `preinstall` hook into this and 31 other packages in the `@redhat-cloud-services` scope. The hook delivers a three-layer obfuscated payload (ROT-9 Caesar cipher over a 1.27M-entry character-code array -> AES-128-GCM decryption with hardcoded keys -> stacked obfuscator.io encoding with PBKDF2+SHA-256 keystream S-box substitution) that downloads a pinned Bun runtime (v1.3.13) from GitHub to execute the worm outside the victim's Node installation. **Credential theft:** Harvests AWS credentials (IMDS, ECS, Secrets Manager, SSM), Azure managed identities, GCP service account tokens, HashiCorp Vault tokens, Kubernetes service account tokens (`/var/run/secrets/kubernetes.io/serviceaccount/token`), GitHub PATs, npm publish tokens, environment variables from ~40 CI platforms (CircleCI, Travis CI, Jenkins, and others), password manager stores (Bitwarden, gopass), and local files (`~/.npmrc`, `~/.netrc`, shell history, database history). Collected data is exfiltrated to attacker-controlled public GitHub repositories. **Privilege escalation:** Exploits Docker socket access to escape containers and modify `/etc/sudoers.d`, granting passwordless sudo to CI runner user accounts. **Self-propagation:** Uses stolen npm credentials to republish tampered tarballs of target packages. Injects a malicious CodeQL workflow into accessible GitHub repositories via the GraphQL `createCommitOnBranch` mutation, exchanges GitHub Actions OIDC tokens for npm publish tokens, and signs the resulting artifacts through Sigstore (Fulcio/Rekor) to appear legitimate. **Persistence and evasion:** Installs a daemon at `/tmp/kitty-<random>`, hijacks `.claude/settings.json` for AI agent persistence, and hijacks `.vscode/tasks.json` for editor task execution. Detects sandbox environments via `__FAKE_PLATFORM__`, `TESTING_TAR_FAKE_PLATFORM__`, and `__IS_DAEMON` environment variables, and probes for EDR tools (CrowdStrike, SentinelOne, Carbon Black, StepSecurity Harden-Runner). --- _-= Per source details.

The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
AI Analysis
Technical Summary
This threat involves a supply chain compromise of the @redhat-cloud-services/javascript-clients-shared npm package (versions 2.0.8, 2.0.9, 2.0.11) via injection of a malicious preinstall hook. The hook executes a three-layer obfuscated payload that downloads and runs a pinned Bun runtime to execute the worm outside the Node environment. The malware steals a broad spectrum of credentials including AWS, Azure, GCP, HashiCorp Vault, Kubernetes tokens, GitHub PATs, npm tokens, and environment variables from numerous CI platforms. It escalates privileges by exploiting Docker socket access to gain passwordless sudo for CI runner users. The worm self-propagates by republishing compromised npm packages using stolen credentials, injecting malicious CodeQL workflows into GitHub repositories, and signing artifacts with Sigstore to appear legitimate. Persistence is achieved via daemon installation and hijacking of AI agent and editor configuration files. The malware detects sandbox environments and probes for EDR tools to evade detection. Due to the extensive compromise, affected systems should be considered fully compromised with immediate secret rotation and package removal recommended.
Potential Impact
The impact includes full system compromise on any computer with the affected package installed or running. The attacker gains access to a wide range of sensitive credentials and tokens across multiple cloud providers and CI platforms, enabling further unauthorized access and lateral movement. Privilege escalation allows the attacker to execute commands with elevated rights. The worm self-propagates by republishing malicious packages and injecting workflows into GitHub repositories, increasing the attack surface. Persistence and evasion techniques make detection and removal difficult. Overall, this results in a severe breach of confidentiality, integrity, and availability of affected systems and environments.
Mitigation Recommendations
No official patch or remediation is currently provided. The vendor has not issued an advisory with a fix. Systems with the affected package versions (=2.0.8, =2.0.9, =2.0.11) should consider themselves fully compromised. Immediate removal of the malicious package is recommended, but this alone may not eliminate all malicious artifacts. All secrets and credentials stored on the compromised system must be rotated immediately from a separate, trusted environment. Monitor for signs of persistence and unauthorized GitHub workflow injections. Follow vendor advisories if and when they become available for official fixes or updates.
