Python Keylogger

DISCLAIMER: THIS PROJECT WAS MADE PURELY FOR LEARNING PURPOSES. I SHALL NOT BE HELD RESPONSIBLE FOR ANYTHING THE PROJECT IS USED FOR. USE AT YOUR OWN RISK.

A simple keylogger proof of concept built with python for the course Information Security(CSL 466). The project uses:

• Dependency and Package Management: Poetry

• Keyboard hooks: keyboard

Features:

• Cross-platform support

• Requires admin requirements on linux machines.

Usage

With Poetry

1. Install Poetry

   Follow the instructions at https://python-poetry.org/docs/#installation

2. Clone this repository and cd into the project directory

   git clone https://github.com/blakeinstein/keylogger && cd keylogger

3. Set up env using poetry

   poetry install

4. Read the help document

   poetry run keylogger -h

5. Run the keylogger with default arguments

   poetry run keylogger

Without Poetry

1. Install python 3.10

2. Clone this repository and cd into the project directory

   git clone https://github.com/blakeinstein/keylogger && cd keylogger

3. (Optional) Setup a virtual env

4. Install dependencies

   pip install -r requirements.txt

5. Read the help document

   python keylogger/main.py -h

6. Run the keylogger with default arguments

   python keylogger/main.py

Working

The project works

• On Linux, by reading /dev/input/input*, hence the root requirment.

• On Windows, using a keyboard hook available from the user32 lib available in user32.dll via the win32api.

• On MacOS, using a similar platform library called carbon. (Untested)

On every new key stroke, the program simply logs the key, if the key matches the terminate key, the program exits unhooking all created hooks.
