A Trojan horse is used to intercept and manipulate calls between a browser and its security mechanisms or libraries.

• A. Malicious JavaScript codes
• B. Trojans
• C. CSRF Attack
• D. Man-in-the-Browser Attack

Answer: (D)

A man-in-the-browser attack is when malware runs inside the browser process and hooks into the browser’s communications with its own security components or libraries. This lets the attacker intercept, inspect, and modify data as it travels between the browser and security checks, cert validation, or cryptographic routines. Because the malware lives inside the browser environment, it can alter what the browser sends or receives, inject fake prompts, or modify form data and requests without the user noticing. This makes it particularly effective for manipulating transactions or bypassing security controls drawn from the browser’s own interfaces. This aligns with the idea of using a Trojan horse to intercept and manipulate calls between a browser and its security mechanisms, since MitB relies on that internal, browser-bound foothold rather than just delivering malicious code on a page or performing an external network attack. It’s more specific than general malicious JavaScript, which is restricted by the browser’s security model, and it’s more precise than a broad Trojan alone or a CSRF flaw, which operate in different contexts.
