## Verdict summary
**Blocked & quarantined** — Arbitrary code execution and theft of npm/GitHub credentials during installation.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Credential Exfiltration
- **Selected version:** 1.0.3
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

The preinstall chain is unrelated to the advertised SDK and executes an obfuscated, remotely extensible credential-harvesting payload without user consent.

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** npm preinstall downloads and runs an obfuscated secondary payload. That payload can fetch and eval remote code and contains token-harvesting logic.

- **Trigger:** npm package installation (preinstall)

- **Impact:** Arbitrary code execution and theft of npm/GitHub credentials during installation.

- **Evidence paths:** package.json, setup.mjs, math\_init.js, lib/cjs/auth.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-04T11:36:56.765Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** install-time staged payload execution with remote eval and credential harvesting

- **Attack narrative:** Installing the package runs setup.mjs, which obtains a Bun executable and uses it to execute the obfuscated math\_init.js payload. The payload includes remote-response eval and token-collection paths, enabling an attacker to alter behavior remotely and exfiltrate developer credentials during installation.

- **Rationale:** The preinstall chain is unrelated to the advertised SDK and executes an obfuscated, remotely extensible credential-harvesting payload without user consent.

- **Files touched:** package.json, setup.mjs, math\_init.js

- **Network endpoints:** https://github.com/oven-sh/bun/releases/download/bun-v1.3.13/

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** package.json invokes setup.mjs during preinstall., setup.mjs downloads Bun from github.com and executes math\_init.js at install time., math\_init.js is heavily obfuscated and dynamically evaluates fetched response content., math\_init.js contains credential-token handling, including npm and GitHub token paths., The installed SDK is small; the unrelated hidden installer payload dominates risk.

- **Evidence against:** lib/cjs/auth.js implements the advertised, user-invoked authentication API.

## Affected versions and remediation

This report applies to @arv-bedrock/auth-admin@1.0.3.

- Avoid installing @arv-bedrock/auth-admin@1.0.3. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
