Which Trojan is described as a Windows-targeted rootkit delivered via Trickler named DoubleFantasy?

• A. Trojan Downloader
• B. Adware
• C. Rootkit Trojans
• D. Banking Trojan

Answer: (C)

Rootkit Trojans are Trojan horses that combine traditional Trojan behavior with rootkit capabilities to conceal their presence on Windows systems. The clue mentions a Windows-targeted rootkit delivered via a loader named Trickler and a component called DoubleFantasy, which points to a stealth-focused malware family designed to hide files, processes, and other artifacts while it persists. That stealthy, kernel- or user-mode concealment is the hallmark of a rootkit, not just a downloader, adware, or banking-focused Trojan. The other options describe different objectives—downloading additional payloads, displaying ads, or stealing financial data—but they don’t imply the concealment techniques characteristic of rootkits.
