Which type of keylogger logs web form inputs by monitoring the submit event during form submission?

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

Answer: (B)

Form-grabbing keyloggers capture the actual values that users enter into web forms by intercepting the data as the form is submitted. When a user submits a form, the browser assembles the payload from the form fields (like username, password, or other sensitive inputs) and sends it to the server. A form-grabbing mechanism hooks into this process or reads the form data in memory at the moment of submission, recording the values before they’re transmitted over the network or encrypted. This makes it especially dangerous for stealing credentials because it grabs the exact data the user entered, not just the keystrokes they typed. This differs from memory-injection-based keystroke logging, which focuses on capturing keys as they’re pressed by injecting into a process to monitor keystrokes. Hypervisor-based keyloggers operate at the virtualization or hardware layer to capture inputs more broadly, and a general keylogger term can refer to methods that don’t specifically target form data during submission.
