In the world of malware for Windows desktop systems, we can find multiple categories, each of which is based on what malicious activity the software presents and how it carries it out. We usually talk about "trojans" and, more specifically, "bank trojans".
This category of malware has been one of the most active for many years, although it's true that in recent years there have been more ransomware attacks that have been detected.
In addition to banking malware, we can find other types of malware, some focused on spying on the activity of their victims, while others are intended to simply remain installed on the infected computer, waiting for the control server to send them the commands with the tasks they must perform. The latter are often used to carry out denial-of-service attacks, using the entire network of infected computers.
Throughout this report, we will review the different types of malware, paying special attention to banking malware that is meant to steal its victims' bank credentials and, ultimately, their money.
