📖 What is Spyware?
Spyware is malicious software that secretly monitors a user's activity and collects personal information without their knowledge. This data, which can include keystrokes, passwords, or browsing history, is then transmitted to a third party for malicious purposes.

🔑 What are the Key Concepts of Spyware?
- ▸ Keyloggers are a specific type of spyware that record every keystroke to steal passwords, credit card numbers, and other sensitive credentials.
- ▸ Data exfiltration is the process where the spyware secretly transmits collected user information to a remote server controlled by the attacker.
- ▸ Spyware often arrives as a bundled installation with free software, where the user unknowingly agrees to the installation via a deceptive EULA.
- ▸ Persistence mechanisms, such as modifying registry keys or startup folders, allow spyware to remain active and restart automatically after a system reboot.
- ▸ Adware is a common subset of spyware that tracks browsing habits to deliver intrusive, targeted advertisements to the user's screen.
🎯 How does Spyware appear on the 220-1102 Exam?
You may be asked to identify a threat when a user reports that their browser's home page has changed and they are seeing frequent, unsolicited pop-up ads that track their search history.
A scenario might describe a computer experiencing slow performance and unauthorized outbound network traffic to an unknown IP, suggesting a hidden process is monitoring the user and stealing data.
Expect questions where you must distinguish between a virus, which focuses on self-replication and damage, and spyware, which prioritizes stealthy data collection and monitoring without necessarily spreading.
