Which banking Trojan can function as both a Trojan itself and as a downloader/dropper for other banking Trojans and is polymorphic?

• A. Dridex
• B. TrickBot
• C. Ursnif
• D. Emotet

Answer: (D)

The idea here is that some banking Trojans are designed not only to steal data themselves but also to act as loaders that fetch and install other banking Trojans, and they do so in a polymorphic way to evade detection. Emotet fits this description best. It started as a banking Trojan, but it evolved into a highly modular downloader that can drop other payloads—often TrickBot or similar banking trojans—onto a system. Its polymorphic nature means its code, filenames, and delivery methods frequently change, making it harder for security solutions to pin down with static signatures. This combination of acting as the initial infection and serving as a dropper for additional banking Trojans, all while staying polymorphic, is what makes Emotet the best answer. Dridex and Ursnif are primarily focused on their own credential theft activities, and TrickBot, while modular, is not as widely recognized for the polymorphic downloader role Emotet provides.
