Which attack category uses drive-by compromise to target web browsers?

• A. Web-Browser-Based Exploitation
• B. Office-Applications-Based Exploitation
• C. Third-Party Applications-Based Exploitation
• D. WinRM

Answer: (A)

Drive-by compromise of web browsers happens when an attacker exploits a vulnerability in the browser or its plugins to deliver malware as soon as a user visits a malicious or compromised webpage. This focus on the browser and the web channel is why web-browser-based exploitation is the best description. Common methods include exploit kits and malvertising that trigger code execution without requiring the user to take a specific action beyond loading the page, leading to silent downloads or payloads. Office-Applications-Based Exploitation would involve malicious documents or macros targeting Office apps, typically delivered via email or downloads rather than through visiting a webpage. Third-Party Applications-Based Exploitation targets other installed software outside the browser, which can be exploited via different vectors but isn’t inherently browser-centered. WinRM is a management/service protocol, not a browser-exploitation category, so it doesn’t describe drive-by compromises to web browsers.
