# Keylogger

Malware (software) or a hardware device that records keystrokes to capture sensitive information such as passwords, credit card numbers, or other data. In TLCTC: a software keylogger maps to `#7 Malware` (foreign code executing via the environment's designed execution capability). A hardware keylogger maps to `#8 Physical Attack` (physical device installation). Captured credentials that are subsequently used map to `#4 Identity Theft`. Typical sequence: `#7 → #4` (software keylogger) or `#8 → #4` (hardware keylogger).
