## Security analysis

### Published attack-surface review

- **Summary:** Installation executes an obfuscated secondary payload. The payload searches for GitHub and npm credentials and sends collected data through concealed network logic.

- **Trigger:** npm preinstall

- **Impact:** Theft and misuse of developer GitHub/npm credentials, potentially enabling repository or package compromise.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-04T11:42:15.556Z

### AI review details

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

- **Mechanism:** Bun-downloaded obfuscated credential-harvesting payload

- **Attack narrative:** On preinstall, setup.mjs downloads or invokes Bun and runs math\_init.js. That large obfuscated script immediately invokes its main routine, discovers credential sources, processes GitHub token variants and npm tokens, and uses network-capable request code to transmit results. This behavior is unrelated to a CSS-modules webpack loader.

- **Rationale:** The package contains a concrete, unconsented install-time credential-harvesting chain, concealed behind an obfuscated payload and external runtime bootstrap. Its legitimate loader entrypoint does not justify this 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 via preinstall., setup.mjs downloads Bun, then executes math\_init.js during installation., math\_init.js is a 728KB obfuscated payload with a top-level jsTXVr() invocation., math\_init.js enumerates credential providers and explicitly handles ghtoken, ghs\_old, ghs\_jwt, and npmtoken., The payload uses filesystem, child\_process, and network request primitives to collect and transmit data.

- **Evidence against:** index.js is a conventional typed-css-modules webpack loader., README.md describes only the loader; it does not document the install-time Bun downloader or payload.

## Public findings

### 1. High: Install Time Lifecycle Scripts
- **Category:** Manifest
- **Confidence:** 90.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@ornikar/typed-css-modules-loader@0.8.7/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/@ornikar/typed-css-modules-loader@0.8.7/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
- **Confidence:** 70.0%

Package source references filesystem APIs.

### 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/@ornikar/typed-css-modules-loader@0.8.7/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 = rwc-client@0.29.14
matchedPath = setup.mjs
matchedIdentity = npm:cndjLWNsaWVudA:0.29.14
similarity = 1.000
summary = normalized source hash matched finalized malicious source
```
