What is the main feature of spyware?

The main feature of spyware is its ability to monitor user activities. Spyware is a type of malicious software designed to gather information about a person or organization without their knowledge. It can track a user's internet browsing habits, collect personal data such as login credentials or credit card details, and send this information back to the entity that created or deployed it.

This covert surveillance can occur through various means, including keylogging, where every keystroke is recorded, or through tracking cookies that can monitor web activity. The primary intent is to gather sensitive information which can be used for identity theft, financial fraud, or unauthorized access to private data. Understanding this helps highlight the importance of using robust security measures and maintaining privacy online.
