Spyware is software that enables a user to obtain covert information about another's computer activities by transmitting data covertly from their hard drive. Spyware is often used to monitor and collect information without the user's knowledge or consent.

Types of Spyware

• Keyloggers: Record keystrokes to capture sensitive information, such as passwords and credit card numbers.
• Adware: Displays unwanted advertisements and collects data on browsing habits.
• Tracking Cookies: Track online activity and collect data on browsing behavior.
• System Monitors: Monitor various activities on a computer, including internet usage, application usage, and file access.

How Spyware Works

Spyware is typically installed without the user's knowledge, often bundled with free software or downloaded from malicious websites. Once installed, it runs in the background, collecting and transmitting data to the attacker.

Impact of Spyware
