Banking trojan
Malware that steals financial credentials and manipulates online-banking sessions, often evolving into general-purpose loaders.
A banking trojan is malware built to steal credentials for online banking and payment services. Classic techniques include web injects (overlaying fake fields on legitimate banking pages), form grabbing, and session hijacking.
Evolution into loaders
Many banking trojans — Emotet, TrickBot, QakBot — outgrew pure banking fraud and became modular loaders that sell access and deliver other payloads such as ransomware. This blurred the line between banking trojans and delivery platforms.
Detection
Watch for process injection into browsers, hooking of networking APIs, and unexpected outbound traffic during banking sessions.
