What it is
A banker trojan is malware built to steal money from online banking. It sneaks onto a PC, watches logins, and can secretly redirect you to fake pages or overlay real ones to grab passwords, 2FA codes, and payment details. It often hides by adding startup tasks and registry entries so it comes back after reboot.
