Spyware Overview

Definition

Spyware is any software that covertly collects user information or monitors user activity without explicit user consent. Typically, spyware applications are bundled with freeware or shareware programs and, once installed, utilize the user’s Internet connection to relay information back to third parties. This information is often used for advertising purposes but can also be exploited to steal sensitive data such as passwords through keystroke-logging.

Examples

  1. Adware: Software that displays unwanted ads on a user’s screen and collects marketing data.
  2. Keyloggers: Programs that record every keystroke made on a computer to capture passwords and other sensitive information.
  3. Trojan Horse: Malicious software disguised as legitimate software, which collects data secretly once installed.
  4. Browser Hijackers: Programs that modify browser settings to redirect searches and homepage settings to unwanted websites.
  5. System Monitors: Applications that monitor user activity on the computer, including taking screenshots and recording Internet browsing behaviors.
