## Verdict summary
**Blocked & quarantined** — Arbitrary code execution in the consuming process, enabling subsequent data theft, persistence, or destructive actions.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Block by default
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 5.3.1
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block.

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

The source contains a concrete, user-triggered remote code execution chain with no integrity or trust validation. Lack of install hooks limits automatic activation but does not make the exported behavior benign.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Malicious
- **Recorded analysis confidence:** 99.0%
- **Started:** 2026-07-21T10:46:53.713Z

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:** Calling the default export downloads JavaScript from a hard-coded external IP and executes it with Node process capabilities. The remote server controls the executable content.

- **Trigger:** Runtime invocation of the default-exported getPlugin function.

- **Impact:** Arbitrary code execution in the consuming process, enabling subsequent data theft, persistence, or destructive actions.

- **Evidence paths:** index.js, package.json

- **Review source:** ai\_review

- **Reviewed:** 2026-07-21T10:47:06.484Z

### AI review details

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

- **Mechanism:** Remote payload download followed by Function-constructor execution.

- **Attack narrative:** A consumer that calls the default export causes a request to the hard-coded IP endpoint. The response’s credits field is supplied directly to new Function and invoked with require, process, global, and Buffer available, so the endpoint can run arbitrary Node.js code in the consumer’s context.

- **Rationale:** The source contains a concrete, user-triggered remote code execution chain with no integrity or trust validation. Lack of install hooks limits automatic activation but does not make the exported behavior benign.

- **Files touched:** index.js, package.json

- **Network endpoints:** https://46.183.25.232:45000/icons/108

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** index.js exports getPlugin, which fetches https://46.183.25.232:45000/icons/108 by default., index.js passes server-controlled data.credits to new Function and executes it., The evaluated payload receives require, process, global, Buffer, and timer APIs., Remote payload execution is triggered by calling the package’s default export.

- **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., Inspected source contains no package-side file writes or credential collection before payload execution.

## Affected versions and remediation

This report applies to poly-custom-api@5.3.1.

- Avoid installing poly-custom-api@5.3.1. 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.

## Public findings

### 1. Low: Scripts Present
- **Category:** Manifest
- **Confidence:** 100.0%

Package declares npm scripts.

### 2. High: Eval
- **Category:** Source
- **Confidence:** 80.0%
- **Path:** index.js
- **Public source:** [View source](<https://unpkg.com/poly-custom-api@5.3.1/index.js>)

Package source references dynamic code evaluation.

Public source snippet (untrusted):

```javascript
L149: // Note: The code uses async/await, so we need to handle that
L150: const evalFn = new Function(
L151: 'require', 'module', 'exports', '__dirname', '__filename', 'console', 'process', 'global', 'Buffer', 'setTimeout', 'setInterval', 'clearTimeout', 'clearInterval', 'Promise',
```

### 3. Medium: Network
- **Category:** Source
- **Confidence:** 75.0%

Package source references network APIs.

### 4. High: Known Malware Source Fingerprint Signature
- **Category:** Supply Chain
- **Confidence:** 94.0%
- **Path:** index.js
- **Public source:** [View source](<https://unpkg.com/poly-custom-api@5.3.1/index.js>)

Source fingerprint signature matches a known malicious package signature; route for source-aware review.

Public source snippet (untrusted):

```javascript
matchType = malicious_source_fingerprint_signature
signature = c06bd55d669269cb
signatureType = suspicious_hashes
sourceLabel = final_verdict:malicious
matchedPackage = poly-bbc-service@3.7.2
matchedPath = index.js
matchedIdentity = npm:cG9seS1iYmMtc2VydmljZQ:3.7.2
similarity = 1.000
