### 1.2 Configuration of ohrwurm$
Configuring ohrwurm$ involves setting its parameters (such as logging location and stealth mode). The configuration file can usually be found in the repository you cloned. Open it with your preferred text editor:
"`bash
nano config.yaml
"`
In this file, you can adjust settings like:
– **log_directory**: Change the directory where logs will be stored.
– **log_format**: Choose how you want the log entries to be formatted.
– **stealth_mode**: Toggle this to enable or disable stealth operations.
After editing, save the file and exit the text editor.

### 1.3 Step-by-Step Usage
Using ohrwurm$ effectively requires understanding its command structure and the options available.
#### Basic Command Structure
"`bash
sudo ./ohrwurm$ [options]
"`
#### Commonly Used Options
– `-h` or `–help`: Display help information.
– `-c
– `-l
– `-s`: Run in stealth mode.
#### Real-World Use Case: Capturing Keystrokes
1. **Start the Tool**: Begin capturing keystrokes by running:
sudo ./ohrwurm$ -s
2. **Perform a Test**: Have another user type into an application (e.g., a web browser or text editor) while ohrwurm$ is active.
3. **View Logs**: After a period, stop ohrwurm$ (usually Ctrl+C). Check the log directory specified in the configuration to view captured keystrokes. Use:
cat /path/to/logfile.log
This will display the keystrokes recorded during the session.

### 1.4 Detailed Technical Explanations
#### How ohrwurm$ Works
ohrwurm$ operates by hooking into the keyboard input stream of the operating system. When a key is pressed, it captures the input in real-time, allowing the user to log everything typed on the keyboard.
##### Key Components:
– **Keylogger Module**: This is the core functionality that captures key events.
– **Stealth Mechanism**: This part ensures that the tool remains undetected by the user and other security software.
– **Log File Handler**: Responsible for writing captured data into a log file for later analysis.
