Analysis and Reverse Engineering of a Banking Trojan Malware from the Zeus Family
1. Introduction and Objectives In this article, we will demonstrate how to conduct a reverse engineering analysis of a banking trojan from the Zeus family. For our study, we have been provided with a single binary file named “fichero.bin.” You can download it from the JMSec GitHub repository: To undertake a study of this nature, you’ll need some basic knowledge of reverse engineering. 2. Setting Up the Laboratory and Description of Materials To begin the exercise, it should be noted that the analysis of the binary is conducted under the Windows 10 operating system. The following list enumerates the tools …
