Spyware – Definition & Detailed Explanation – Computer Networks Glossary Terms

I. What is Spyware?

Spyware is a type of malicious software that is designed to secretly gather information about a person or organization without their knowledge or consent. This information can include browsing habits, keystrokes, personal information, and more. Spyware is often installed on a computer without the user’s knowledge, typically through deceptive means such as email attachments, software downloads, or malicious websites.

II. How Does Spyware Work?

Spyware works by secretly monitoring a user’s activities on their computer. This can include tracking their internet browsing habits, capturing keystrokes, logging passwords, and more. Once installed on a computer, spyware can run silently in the background, collecting data and sending it back to the attacker. This data is then used for various malicious purposes, such as identity theft, fraud, or targeted advertising.

There are several risks associated with spyware, including:

1. Privacy invasion: Spyware can collect sensitive information about a user without their knowledge, such as passwords, credit card numbers, and personal emails.

2. Identity theft: Spyware can be used to steal a user’s identity by capturing personal information and using it for fraudulent purposes.

3. Financial loss: Spyware can lead to financial loss by stealing credit card information, banking details, or other sensitive financial data.

4. System instability: Spyware can slow down a computer’s performance, cause crashes, and lead to other system issues.

5. Legal consequences: In some cases, the use of spyware can be illegal and result in legal consequences for the attacker.
