## Security analysis

### Published attack-surface review

- **Summary:** Importing index.js activates concealed remote payload retrieval, decoding, file creation, and process invocation. This is unrelated to an array utility.

- **Trigger:** Runtime require/import of elephant-array-utils.

- **Impact:** Unconsented remote code execution in the importing user's environment.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-07-30T11:32:13.466Z

### AI review details

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

- **Mechanism:** Obfuscated import-time downloader, payload dropper, and child-process launcher.

- **Attack narrative:** The main entrypoint immediately executes an obfuscated IIFE. Its source loads OS/filesystem helpers and hidden modules, processes a remote response, derives a file under the user home directory, writes decoded content, and starts a hidden child process from the home-directory context. Empty error handlers suppress failures. The payload host and dropped filename are string-obfuscated, but the downloader-to-write-to-launch chain is directly present in source.

- **Rationale:** This package has concrete import-time payload staging and execution behavior, not array utility functionality. Obfuscation and hidden execution establish a malicious remote-code-execution chain.

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

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** index.js is entirely obfuscated and runs a top-level IIFE on import., The IIFE loads os, fs and additional hidden modules, then uses a Promise-based remote-response flow., It derives a path from os.homedir(), writes response-derived decoded bytes with a write mode, then invokes a hidden child-process API., Execution is concealed with empty catch handlers and windowsHide options., package.json exposes index.js as the sole main entrypoint, so requiring the package triggers this behavior.

- **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., No plaintext endpoint is recoverable without executing the package decoder.

## Public findings

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

Package declares npm scripts.

### 2. High: Obfuscated Payload Loader
- **Category:** Source
- **Confidence:** 86.0%
- **Path:** index.js
- **Public source:** [View source](<https://unpkg.com/elephant-array-utils@1.0.6/index.js>)

Source contains an obfuscator-style string-array loader that reconstructs and executes hidden code.

Public source snippet (untrusted):

```javascript
L1: function c(b,d){b=b-(-0x44b*0x5+-0x3a*-0x37+0x9dc);var e=a();var f=e[b];if(c['zmwvKT']===undefined){var g=function(l){var m='[redacted]...
```

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

Package source contains high-entropy string patterns.

### 4. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 85.0%

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