Which keylogger uses memory injection to log keystrokes and can bypass UAC in Windows?

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

Answer: (D)

Memory injection describes a technique where code is loaded into another process’s memory space to run alongside it and observe or intercept its operations. When a keylogger uses this approach, it can hook into the OS’s input pathways at a very low level, allowing it to capture keystrokes across applications, not just within a specific window or browser. Because the injected code runs inside a legitimate process or within a higher-privilege context, it can operate with elevated rights. That elevated presence helps it bypass prompts or protections like Windows User Account Control, which is designed to block unauthorized actions by untrusted software. In short, logging keystrokes by inserting code into memory gives the attacker visibility into keyboard activity while also giving a path to operate with higher privileges, making UAC less of a barrier. Form-grabbing-based keyloggers focus on capturing data from user input fields as data is entered into forms, often by intercepting the data before it’s encrypted or transmitted, which is a different approach than injecting into memory to observe keystrokes. JavaScript-based keyloggers run inside a web page and are limited by browser security models, sandboxing, and the site’s content restrictions, so they don’t typically achieve system-wide keystroke logging or privilege elevation. The term KeyGrabber is generic and doesn’t specify the underlying method, so it doesn’t convey the same capability as memory injection in terms of low-level capture and potential privilege bypass.
