Which of the following is a common type of malware besides ransomware?

Spyware is indeed a common type of malware that operates by secretly monitoring and collecting user information from a device. It often gathers personal data, such as login credentials, browsing habits, and sensitive information without the user's knowledge or consent. Unlike ransomware, which primarily locks or encrypts user data for financial gain, spyware focuses on surveillance and can lead to identity theft or further exploitation of personal information.

In contrast to spyware, phishing is a tactic used to trick individuals into revealing sensitive information, but it is not classified as malware itself. SQL Injection and Cross-Site Scripting are both types of injection attacks aimed at exploiting vulnerabilities in web applications rather than being classified as malware in the traditional sense. Therefore, spyware stands out as a recognized category of malware, highlighting its prevalence and importance as a security concern.
