Explanation

Ad blockers are correct because drive-by compromise attacks typically use malicious advertisements (malvertising) or injected scripts on web pages to silently download and execute malware when a user visits a compromised or malicious site. Ad blockers prevent these malicious ads and scripts from loading in the first place, cutting off the primary delivery vector.

  • VPN (B) encrypts your traffic and masks your IP, but does nothing to stop malicious code from executing in your browser once you load a page.
  • Incognito mode (C) only prevents local browsing history from being saved; it provides no protection against malicious content being served to your browser.
  • Browsing known websites (D) reduces risk but doesn't eliminate it - legitimate, well-known sites can still serve malvertising through compromised third-party ad networks (e.g., major news sites have been victimized).

Memory tip: Think of a drive-by as a sniper firing through your browser window - an ad blocker closes the window before the shot arrives, while a VPN or incognito mode only changes your disguise outside.
