Which Trojan type is primarily associated with defacing websites by altering HTML content?

• A. Restorator
• B. Defacement Trojans
• C. ICMP Trojans
• D. BasBanke

Answer: (B)

Defacement Trojans are built to vandalize a site by changing the HTML that is served to visitors. When these Trojans compromise a web server or hosting account, they replace the homepage file (like index.html) or inject modified HTML and scripts, so the attacker’s message or image appears to anyone who visits the page. This direct alteration of the site's visible content is what defines this Trojan family. In practice, attackers often gain access through weak credentials, exposed CMS plugins, or insecure FTP, then upload the defacement payload or swap out the original HTML. The goal is public display of the defacement rather than stealing data. Other Trojan types focus on different outcomes, such as restoring original files after tampering, using the ICMP protocol for covert communication, or stealing banking credentials. The one that aligns with defacing by HTML modification is the Defacement Trojan.
