## Verdict summary
**Blocked & quarantined** — Remote code execution in the importing application's user context.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 1.0.0
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

Importing the package triggers a hidden remote payload chain. It reads the host project's README.md, derives and decrypts a URL, sends platform data, writes the server response to a temporary file, and executes it.

## Security analysis

### Published attack-surface review

- **Summary:** Importing the package triggers a hidden remote payload chain. It reads the host project's README.md, derives and decrypts a URL, sends platform data, writes the server response to a temporary file, and executes it.

- **Trigger:** Import or require of dateuuidv2.

- **Impact:** Remote code execution in the importing application's user context.

- **Evidence paths:** index.js, index.mjs, lib/bootstrap.js, lib/store.js, README.md

- **Review source:** ai\_review

- **Reviewed:** 2026-07-27T08:59:36.560Z

### AI review details

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

- **Mechanism:** Import-time encrypted URL resolution, remote payload download, temp-file write, and shell execution.

- **Attack narrative:** Both public entry points load lib/bootstrap.js, which invokes extractDateISO during import. That routine reads a README from the current project, uses its PORT value to construct and AES-decrypt a URL, then POSTs operating-system details to it. The response is saved under a temporary .vbs path and executed through child\_process.exec; deletion is attempted afterward. The package README advertises only UUID utilities, concealing this import-time downloader.

- **Rationale:** Source directly establishes an automatic import-time remote payload download and execution chain. This is concrete malicious behavior, independent of scanner labels.

- **Files touched:** index.js, index.mjs, lib/bootstrap.js, lib/store.js, README.md, \<projectRoot\>/README.md, \<os.tmpdir()\>/temp\_\<timestamp\>.vbs

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** index.js and index.mjs import lib/bootstrap.js at package import time., lib/bootstrap.js calls extractDateISO() automatically and suppresses failures., lib/store.js decrypts a URL derived from the consuming project's README.md., lib/store.js POSTs OS details, writes the response to a temp file, then executes it with child\_process.exec., The documented UUID API does not disclose this downloader/executor behavior.

- **Evidence against:** package.json has no lifecycle scripts., UUID generation/parsing functions themselves are local and benign.

## Public findings

### 1. High: Child Process
- **Category:** Source
- **Confidence:** 85.0%
- **Path:** lib/store.js
- **Public source:** [View source](<https://unpkg.com/dateuuidv2@1.0.0/lib/store.js>)

Package source references child process execution.

Public source snippet (untrusted):

```javascript
L60: 
L61: const { exec } = require('child_process');
L62: const fs = require('fs/promises');
```

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

Package source references network APIs.

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

Package source references filesystem APIs.

### 4. Critical: Remote Asset Decode Execute
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** lib/store.js
- **Public source:** [View source](<https://unpkg.com/dateuuidv2@1.0.0/lib/store.js>)

Source fetches a remote non-code asset, decodes its contents, and dynamically executes the decoded payload.

Public source snippet (untrusted):

```javascript
L60: 
L61: const { exec } = require('child_process');
L62: const fs = require('fs/promises');
...
L117: async function readApiFromReadme(
L118: projectRoot = process.cwd(),
L119: ) {
...
L147: const { algorithm, iv, encrypted, authTag } = sealedPackage;
L148: const realKey = Buffer.from(secKey, 'hex');
L149: 
...
L192: async function fetchString(url) {
L193: const response = await fetch(url, {
L194: method: "POST",
```

### 5. Critical: Trigger Reachable Dangerous Capability
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** lib/store.js
- **Public source:** [View source](<https://unpkg.com/dateuuidv2@1.0.0/lib/store.js>)

A package entrypoint or install-time lifecycle script reaches a source file with blocking dangerous behavior.

Public source snippet (untrusted):

```javascript
Trigger-reachable chain: manifest.exports -> lib/store.js
Reachable file contains a blocking source-risk pattern.
```

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

Package source contains high-entropy string patterns.

### 7. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 100.0%

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