## Security analysis

### Published attack-surface review

- **Summary:** Installation automatically downloads an interpreter and runs an obfuscated credential-harvesting payload. The payload searches for GitHub authentication tokens and uploads collected data.

- **Trigger:** npm install, via the preinstall lifecycle hook

- **Impact:** The installer environment's GitHub credentials may be stolen.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-04T11:55:39.867Z

### AI review details

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

- **Mechanism:** staged Bun payload execution and GitHub-token exfiltration

- **Attack narrative:** On npm installation, package.json invokes setup.mjs. That script obtains Bun if absent and executes the obfuscated math\_init.js payload. The payload contains token-source handling for ghtoken, ghs\_old, and ghs\_jwt and uses obfuscated fetch upload routines, constituting credential exfiltration.

- **Rationale:** This is unconsented preinstall execution of an obfuscated payload that collects and transmits GitHub credentials. The Bun download is a staging mechanism, not a package-aligned UI-library action.

- **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 \`node setup.mjs\` as preinstall., setup.mjs downloads Bun from GitHub and executes math\_init.js during installation., math\_init.js is a 728KB obfuscated executable payload., math\_init.js enumerates \`ghtoken\`, \`ghs\_old\`, and \`ghs\_jwt\` credential sources., The payload sends collected data through obfuscated fetch-based upload logic.

- **Evidence against:** Published exports otherwise describe a React UI component library.

## Public findings

### 1. High: Install Time Lifecycle Scripts
- **Category:** Manifest
- **Confidence:** 90.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@servicetitan/anvil2@3.9.2/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/@servicetitan/anvil2@3.9.2/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. Medium: Environment Vars
- **Category:** Source
- **Confidence:** 75.0%

Package source references environment variables.

### 6. Low: Filesystem
- **Category:** Source
- **Confidence:** 70.0%

Package source references filesystem APIs.

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

Package source contains high-entropy string patterns.

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

Package source contains URL literals.

### 9. 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.

### 10. Low: No License
- **Category:** Manifest
- **Confidence:** 80.0%

Package manifest does not declare a clear license.

### 11. High: Known Malware Source Similarity
- **Category:** Static
- **Confidence:** 97.0%
- **Path:** setup.mjs
- **Public source:** [View source](<https://unpkg.com/@servicetitan/anvil2@3.9.2/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 = @hubsync/web-sdk-react@6.3.26
matchedPath = setup.mjs
matchedIdentity = npm:QGh1YnN5bmMvd2ViLXNkay1yZWFjdA:6.3.26
similarity = 1.000
summary = normalized source hash matched finalized malicious source
```

### 12. High: Previous Version Dangerous Delta
- **Category:** Supply Chain
- **Confidence:** 93.0%
- **Path:** setup.mjs
- **Public source:** [View source](<https://unpkg.com/@servicetitan/anvil2@3.9.2/setup.mjs>)

This package version adds a dangerous source file absent from the previous stored version; route for source-aware review.

Public source snippet (untrusted):

```javascript
matchType = previous_version_dangerous_delta
matchedPackage = @servicetitan/anvil2@3.7.1
matchedIdentity = npm:QHNlcnZpY2V0aXRhbi9hbnZpbDI:3.7.1
similarity = 0.925
summary = stored previous version shares package body but lacks this dangerous source file
```
