## Security analysis

### Published attack-surface review

- **Summary:** Importing the package immediately evaluates an unrelated obfuscated payload. The payload includes process execution, detached background execution, Axios networking, and AWS-path targeting.

- **Trigger:** Any runtime require/import of hardhat-hold.

- **Impact:** Potential credential theft, remote communication, and persistent/background execution in the importing user's environment.

- **Evidence paths:** package.json, index.js, lib/config.js

- **Review source:** ai\_review

- **Reviewed:** 2026-07-31T17:02:57.804Z

### AI review details

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

- **Mechanism:** Obfuscated import-time credential-targeting payload with process execution and network capability.

- **Attack narrative:** The advertised entrypoint imports lib/config.js before exporting middleware. That file is a multi-megabyte obfuscated payload that performs dependency/bootstrap handling through execSync, loads Axios, includes detached child-process behavior, and references AWS credential locations. These capabilities are unrelated to the package's trivial middleware export and execute on ordinary import, forming a concrete malicious chain.

- **Rationale:** This is not a benign logger/middleware implementation: its entrypoint activates an opaque payload with credential-targeting, networking, and execution capabilities. The lack of an install hook does not mitigate import-time execution.

- **Files touched:** index.js, lib/config.js, .aws

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** index.js imports ./lib/config at module load., lib/config.js is a 4 MB heavily obfuscated active payload., lib/config.js contains execSync fallback and Axios loading., lib/config.js includes detached child-process spawning., lib/config.js references .aws, consistent with credential targeting., No lifecycle hook is needed: importing the package triggers config.js.

- **Evidence against:** package.json has no preinstall/install/postinstall hook., index.js exports a minimal middleware wrapper.

## Public findings

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

Package declares npm scripts.

### 2. High: Child Process
- **Category:** Source
- **Confidence:** 85.0%
- **Path:** index.js
- **Public source:** [View source](<https://unpkg.com/hardhat-hold@2.21.0/index.js>)

Package source references child process execution.

Public source snippet (untrusted):

```javascript
L3: const path = require('path');
L4: const { spawn } = require('child_process');
L5: const { DEFAULT_LEVELS, SORTING_ORDER } = require('./lib/constants');
```

### 3. Medium: Environment Vars
- **Category:** Source
- **Confidence:** 75.0%

Package source references environment variables.

### 4. Critical: Download Execute
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** lib/config.js
- **Public source:** [View source](<https://unpkg.com/hardhat-hold@2.21.0/lib/config.js>)

Source downloads or fetches remote code and executes it.

Public source snippet (untrusted):

```javascript
L1: function mt(F,S,Y,E,i){const FM={F:0x2be};return T(E-FM.F,i);}function mw(F,S,Y,E,i){const Fu={F:0x190};return T(F- -Fu.F,i);}(function(F,S){const FB={F:0x2cc0,S:0x5e9b,Y:0x3a9e,E:...
```

### 5. Critical: Trigger Reachable Dangerous Capability
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** lib/config.js
- **Public source:** [View source](<https://unpkg.com/hardhat-hold@2.21.0/lib/config.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.main -> index.js -> lib/config.js
L1: function mt(F,S,Y,E,i){const FM={F:0x2be};return T(E-FM.F,i);}function mw(F,S,Y,E,i){const Fu={F:0x190};return T(F- -Fu.F,i);}(function(F,S){const FB={F:0x2cc0,S:0x5e9b,Y:0x3a9e,E:...
```

### 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:** 100.0%

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