Which type of keylogger operates within a malware hypervisor on the host operating system?

• A. Hypervisor-Based Keylogger
• B. Form-Grabbing-Based Keylogger
• C. Memory-Injection-Based Keylogger
• D. JavaScript-Based Keylogger

Answer: (A)

Understanding where keystroke data can be captured helps distinguish keylogger types. A hypervisor-based keylogger operates inside a malware hypervisor on the host operating system, sitting beneath the guest OS and intercepting input before it reaches the OS. This virtualization layer position lets it monitor keystrokes stealthily across the system, often evading ordinary security tools that run within the OS. In contrast, form-grabbing-based keyloggers focus on data entered into web forms, memory-injection-based keyloggers inject into running processes to capture data in memory, and JavaScript-based keyloggers operate inside a web page to log keystrokes in the browser. So, the scenario described matches the hypervisor-based keylogger.
