npm-viewscripts

Identify potentially malicious npm scripts in a project.

codeship GitHub NPM

Overview

This project is a Node.js CLI tool to identify which of a project's existing dependencies are utilising npm lifecycle scripts, which could be malicious.

The currently configured npm scripts the tool will identify are: preinstall, postintall, preuninstall, postuninstall

Note: This project is to educate, so should not be used as a complete npm security solution.

Installation

# install globally, using npm
$ npm install npm-viewscripts -g

# Run the cli on a project
$ cd my-node-project
$ npm install
$ npm-viewscripts

Usage

$ npm-viewscripts

  Usage
    $ npm-viewscripts [path]

  Options
    path  Modules folder  [Default: node_modules]

Understanding the result

Positive report example:

Potentially unsafe scripts found. These should be reviewed for safety
Module name: monorepo-symlink-test Type: postinstall

The above output informs us that the monorepo-symlink-test is running a postinstall script, so we should review that, and ensure that it is safe.

Negative report example:

No potentially unsafe scripts found.

No modules in the project are currently using scripts which could be used maliciously.

npm i npm-viewscripts
