The Idea

While attempting to hack PayPal with me during the summer of 2020, Justin Gardner (@Rhynorater) shared an interesting bit of Node.js source code found on GitHub. The code was meant for internal PayPal use, and, in its package.json file, appeared to contain a mix of public and private dependencies — public packages from npm, as well as non-public package names, most likely hosted internally by PayPal. These names did not exist on the public npm registry at the time.

Hardware Required

  • Arduino UNO
  • IR Sensor
  • Robot chassis
  • Connecting wires
  • Battery

Procedure

These are the following steps to follow:

1) Step 1 :

The code was meant for internal PayPal use, and, in its package.json file, appeared to contain a mix of public and private dependencies — public packages from npm, as well as non-public package names, most likely hosted internally by PayPal. These names did not exist on the public npm registry at the time.

2) Step 2 :

The code was meant for internal PayPal use, and, in its package.json file, appeared to contain a mix of public and private dependencies — public packages from npm, as well as non-public package names, most likely hosted internally by PayPal. These names did not exist on the public npm registry at the time.

3) Step 3 :

The code was meant for internal PayPal use, and, in its package.json file, appeared to contain a mix of public and private dependencies — public packages from npm, as well as non-public package names, most likely hosted internally by PayPal. These names did not exist on the public npm registry at the time.
