Project Overview

Initially developed as a simple local keylogger, the project was expanded to include a Server-Client architecture. This allows a remote "attacker" (Server) to receive captured telemetry from a "victim" (Client) over a network connection

Technical Logic

The system consists of two primary modules:

1. The Client (Victim): A hidden software that connects to the server and sends the collected logs.
2. The Server (Attacker): A listener that waits for the client to establish a connection and push the collected logs.
3. The Keylogger: A stealthy background process that hooks keyboard input and buffers data to a local log file.

Demonstration Workflow

The following steps are shown in the demonstration video:

1. Baseline Check: Verification that the local log file is empty and the process is not yet active.
2. Execution: Launching the keylogger; it operates silently with no GUI, visible only in the System Task Manager.
3. Data Capture: Actively writing "Text" and [ctrl] s to trigger a logging event.
4. Verification: Confirming the log file has been updated with the captured keystrokes.
5. Exfiltration: Launching the Server-Client interface. The client automatically connects to the server and transmits the log content.
