Spyware
Definition
Spyware is a type of malware that secretly observes the user's computer activities without permission and reports it to the software's author.
Why It Matters
Spyware is a major threat to privacy. It can be used to steal sensitive information like passwords, credit card numbers, and browsing habits, often for the purpose of identity theft or targeted advertising.
Contextual Example
A keylogger is a type of spyware that records every keystroke a user makes. This information is then sent to an attacker, allowing them to capture usernames, passwords, and private messages.
Common Misunderstandings
- Spyware often gets installed on a system bundled with other "free" software.
- Adware is a related type of malware that focuses on displaying unwanted advertisements.
