Risky Biz News: URSNIF goes from banking trojan to backdoor, dreaming of ransomware profits

Mandiant cites several reasons for URSNIF's new radical redesign. At least two leaks of its codebase, multiple branches of the same codebase that had slowly diverged and were making it harder to support features across different botnets, but also an ancient codebase that had finally reached the end of the road when IE was removed from Windows.
Honestly, it's a surprise that URSNIF lasted this long still operating on a banking trojan model. It had become obvious in the mid-2010s that the banking malware scene was dying, at least on the desktop.
Banks, tired of a decade of heists from customer accounts, had rolled out advanced multi-factor authentication and transaction verification systems. While not foolproof, these systems did their job and made it more time-consuming for banking malware operators to steal money from compromised accounts.
