Zloader Learns Old Tricks

May 1, 2024, 11:09 p.m.

Description

Zloader (a.k.a. Terdot, DELoader, or Silent Night) is a modular trojan based on leaked ZeuS source code. Zloader has continued to evolve since its resurrection around September 2023 after an almost two-year hiatus. The latest version, 2.4.1.0, introduces a feature to prevent execution on machines that differ from the original infection. This anti-analysis technique was present in the original ZeuS 2.X code but implemented differently.
