  • Monitor User Activity: Allow for the tracking and recording of keystrokes, which can be used for legitimate monitoring purposes or malicious intent.
  • Pose Security Risks: Can capture sensitive information, leading to privacy breaches, identity theft, and financial fraud.
  • Aid in Security Investigations: Used in cybersecurity to investigate unauthorized access or malicious activities.

Key Concepts of Keyloggers

  • Software Keyloggers: Programs installed on a device to capture and log keystrokes.
  • Hardware Keyloggers: Physical devices attached to the keyboard or computer to record keystrokes.
  • Stealth Mode: Keyloggers often operate in stealth mode, running undetected in the background.
