How can I use JavaScript to create a basic keylogger for ethical hacking purposes

Answer 1

You can create a simple keylogger in JavaScript. It listens for key presses and logs them:

• document.addEventListener('keydown', ...): Listens for any key press on the page.
• event.key: Captures which key was pressed.
• console.log(): Logs the key to the browser's console.

To run this JavaScript keylogger, follow these steps:

• Right-click anywhere on a webpage.
• Select "Inspect" or press F12.
• Go to the "Console" tab.

Copy and paste this code into the console:

After running the script, start typing on the webpage. Each key press will be logged in the console, showing messages like:

Key pressed: H
Key pressed: e
Key pressed: l
Key pressed: l
Key pressed: o
