Keylogger

A Keylogger is a type of surveillance technology (software or hardware) used to monitor and record each keystroke typed on a specific computer's keyboard.

Captured String

Note: HTTPS encryption protects data in transit, but keyloggers capture data at the endpoint (your keyboard) before it's encrypted.

Interactive: Type into the fake banking login on the left. Watch the "Attacker's Log" on the right capture everything instantly.

How it Works

  • InfectionKeyloggers often arrive as malware via phishing emails or infected downloads.
  • StealthThey run quietly in the background, invisible to the user, recording everything (passwords, emails, chats).
  • BypassBecause they sit on the device itself, they capture data before it gets encrypted by HTTPS/TLS.

Prevention & Defense

Antivirus / Anti-MalwareRegular scans can detect known keylogging software signatures.
Virtual KeyboardsOn-screen keyboards can sometimes bypass hardware keyloggers or simple software hooks.
Multi-Factor Authentication (MFA)Even if they steal your password, they can't log in without the second factor (like a phone code).
