Over the years, many studies and companies dedicated to cybersecurity have come to the conclusion that the number of malware variants that are created in a month could be over 30 million, a very high figure. with respect to previous years. Most of all these threats affect Windows operating systems, although in recent months, it is true that there has been a significant diversification.
The first thing to understand is that these malware can be rare (not very frequent but … It can happen). These can be contracted through Web pages that contain malicious programs or some hidden Trojan like the example that we will see.
This virus was capable of being invisible to antivirus programs and was responsible for injecting code into the handling routines of mouse input / output functions. But why do this? Well, the reason for choosing this function is that you could remotely control where you want to click on the user’s computer completely remotely and thus the attacker could redirect you to sites that contain malware or a malicious file.
As we have indicated, the Trojan is at all times invisible to antivirus. For this to be the case, all it does is time the actions it has to carry out so as not to try to arouse suspicions not only in antivirus software but also in the operating system itself. 20 minutes after the infection, the handler routines are already installed and you have waited for the operating system and antivirus software to not alert the user to an attempt to modify the registry. It is now when you will proceed to carry it out and modify the labels of the old routines for yours.
So how do we detect this malware? Well beware of this Mouse malfunction
