## Security analysis

### Published attack-surface review

- **Summary:** Install-time code downloads an interpreter and executes an obfuscated payload. The payload supports remotely supplied code execution and credential-oriented processing.

- **Trigger:** npm preinstall

- **Impact:** Arbitrary remote code execution and potential credential exfiltration on the installing machine.

- **Evidence paths:** package.json, setup.mjs, math\_init.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-04T12:13:33.012Z

### AI review details

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

- **Mechanism:** downloads Bun, executes math\_init.js, then evals fetched content

- **Attack narrative:** npm preinstall invokes setup.mjs. It uses HTTPS to download a Bun binary from GitHub when Bun is unavailable, then runs the bundled 728KB obfuscated math\_init.js. That payload performs outbound requests, evals fetched response content, and includes GitHub-token handling, creating a concrete remote-code-execution and credential-theft chain during installation.

- **Rationale:** The lifecycle script is unrelated to the advertised visualization package and deliberately bootstraps an interpreter for an obfuscated payload. Its fetched-content eval and token-oriented logic establish malicious install-time behavior.

- **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:** package.json runs setup.mjs during preinstall., setup.mjs downloads Bun from github.com and executes math\_init.js., math\_init.js is a 728KB obfuscated payload invoked at install., math\_init.js fetches content and evals its response., math\_init.js contains GitHub-token handling and outbound request logic.

- **Evidence against:** The declared runtime entrypoints are tab-container UI bundles.

## Public findings

### 1. High: Install Time Lifecycle Scripts
- **Category:** Manifest
- **Confidence:** 90.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@nebula.js/sn-tabbed-container@2.4.1/package.json>)

Package defines install-time lifecycle scripts.

Public source snippet (untrusted):

```json
scripts.preinstall = node setup.mjs
```

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

Package declares npm scripts.

### 3. Low: Eval
- **Category:** Source
- **Confidence:** 45.0%
- **Path:** math\_init.js
- **Public source:** [View source](<https://unpkg.com/@nebula.js/sn-tabbed-container@2.4.1/math_init.js>)

Package source references a known benign dynamic code generation pattern.

Public source snippet (untrusted):

```javascript
L1: // @bun @bun-cjs
L2: var MmgoCP,etDiOOB,JqTtnbZ,bc3Kak,ZQmUTyQ,TTUgga,MDX6yrw,h8wMJNB,CabwE2L,x5ErqV;function WV8StW(MmgoCP,etDiOOB,JqTtnbZ){for(JqTtnbZ=0x0;JqTtnbZ<etDiOOB;JqTtnbZ++)MmgoCP.push(MmgoCP...
```

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

Package source references network APIs.

### 5. Low: Filesystem
- **Category:** Source

### 6. Low: High Entropy Strings
- **Category:** Supply Chain
- **Confidence:** 55.0%

Package source contains high-entropy string patterns.

### 7. Low: Url Strings
- **Category:** Supply Chain
- **Confidence:** 65.0%

Package source contains URL literals.

### 8. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 80.0%

Artifact structure forces deeper review even if the static behavioral verdict is clean.

### 9. High: Known Malware Source Similarity
- **Category:** Static
- **Confidence:** 97.0%
- **Path:** setup.mjs
- **Public source:** [View source](<https://unpkg.com/@nebula.js/sn-tabbed-container@2.4.1/setup.mjs>)

Source file is highly similar to a previously finalized malicious package; route for source-aware review.

Public source snippet (untrusted):

```javascript
matchType = normalized_sha256
matchedPackage = @servicetitan/anvil2@3.9.2
matchedPath = setup.mjs
matchedIdentity = npm:QHNlcnZpY2V0aXRhbi9hbnZpbDI:3.9.2
similarity = 1.000
summary = normalized source hash matched finalized malicious source
```
