What is the browser-based attack that runs malicious code inside the browser and persists even after closing or navigating away from the malicious web page called?

• A. Cookies
• B. MarioNet
• C. CAPTCHA
• D. Direct Timing Attack

Answer: (B)

This question is about browser-based persistence where malicious code runs inside the browser and continues to operate even after you close the page or navigate away. That behavior is described by MarioNet, a term used for a browser-based botnet that leverages the browser’s runtime to perform tasks and stay active through background processes or ongoing connections to a remote controller. Cookies are just data stored by the browser, CAPTCHA is a human-verification test, and a Direct Timing Attack is a side-channel technique; none of those involve running malicious code in the browser that persists after leaving a page.
