Which Trojan category uses vulnerable service protocols to attack the victim's machine?

• A. Restorator
• B. HTTP/HTTPS Trojans
• C. Service Protocol Trojans
• D. ICMP Trojans

Answer: (C)

Exploiting weaknesses in network service protocols to attack a machine is what this category focuses on. Service Protocol Trojans target services that speak specific protocols and take advantage of flaws in how those protocols are implemented or how the service handles crafted requests. By sending specially formed messages to a listening port or by exploiting misconfigurations, the Trojan can trigger remote code execution, install itself, or gain control over the victim’s system through that service. This is distinct from HTTP/HTTPS Trojans, which rely on web traffic; ICMP Trojans, which rely on ICMP messages; and Restorator-type behavior, which operates through other means rather than exploiting protocol services.
