Which Trojan is associated with capturing a single-use password for online banking transactions?

• A. HTML Injection
• B. E-banking Trojans
• C. Dreambot Trojans
• D. TAN Gabber

Answer: (B)

One-time passwords used to authorize online banking transactions are a common target for e-banking trojans. These threats operate inside the victim’s browser during a banking session, using web injects to modify pages and form grabbing to capture credentials and the accompanying one-time codes (TANs or OTPs). The goal is to obtain both the login details and the single-use password needed to authorize a fraudulent transfer, so this category directly fits the scenario. HTML injection is a technique rather than a Trojan family, and while Dreambot is a banking Trojan, the broader category that specifically covers capturing such one-time passwords during online banking is e-banking trojans. TAN Gabber is a specific variant focusing on TAN capture, but the question points to the general category rather than a single variant.
