Malicious code in @redhat-cloud-services/compliance-client (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.

AI Analysis
Technical Summary
This threat involves malicious code injected into the @redhat-cloud-services/compliance-client npm package (versions 4.0.3, 4.0.4, 4.0.6) as part of a supply chain attack named "Mini Shai-Hulud." The attacker added a preinstall hook that executes a three-layer obfuscated payload to download and run a Bun runtime outside the Node environment. The malware steals a broad spectrum of credentials including AWS, Azure, GCP, HashiCorp Vault, Kubernetes tokens, GitHub PATs, npm tokens, environment variables from numerous CI platforms, password manager data, and local sensitive files. It escalates privileges by exploiting Docker socket access to gain passwordless sudo rights for CI runner accounts. The worm self-propagates by republishing malicious package versions using stolen npm credentials, injecting malicious CodeQL workflows into GitHub repositories, and signing artifacts via Sigstore to appear legitimate. Persistence is maintained 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. Systems with this package installed should be treated as fully compromised.
Potential Impact
The impact is severe and multifaceted: full system compromise is likely due to credential theft across multiple cloud providers and local secrets, privilege escalation allowing container escape and root-level access, self-propagation enabling widespread infection through npm and GitHub workflows, and persistence mechanisms that maintain long-term access. The attacker gains control over CI environments and developer workstations, potentially leading to extensive data exfiltration and further supply chain contamination.
Mitigation Recommendations
No official patch or remediation is currently provided. The package should be removed immediately. Because full system compromise is likely, all secrets and credentials stored on the affected system must be rotated from a different, trusted machine. Monitor for signs of the described persistence mechanisms and remove any detected malicious daemons or configuration hijacks. Consider rebuilding affected systems from clean backups to ensure complete eradication of the malware.

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 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).
