Kernel-Based Keylogger

A basic kernel-level keylogger module made using C. The module captures and logs keyboard events in the kernel log.

Prerequisites

• A Linux system.
• Kernel development headers installed.
• Root access.

Building the Module

1. Clone the repository to your local system.

2. Open a terminal and navigate to the project directory.

3. Build the module by running the following command:

make

On success, This will generate a kernel module file called keylogger.ko

Loading the module

sudo insmod keylogger.ko

This will load the keylogger module into the kernel.

dmesg

You can see a log message that says module is loaded.

Now you can try typing anything and just run dmesg to see the keylogs.

Unloading the module

sudo rmmod keylogger

This will remove the module from the kernel
