One of the sections that most concerns users is everything related to the privacy and security on their teams. One of the reasons for all this is that we are increasingly working with more private and sensitive data. Next, we are going to show you some of the types of malware with which we must be more careful.
If we take into consideration that Windows is the most used desktop system, we can understand that the creators of malicious code focus on it. This means that computers based on this software are the most frequent target of cybercriminals and their different varieties of malware. These malicious elements have been with us for decades, and have not stopped evolving.
Therefore, at this time we can find a good number of different types. That is why we will now talk about the most used and dangerous malware formats at the moment and what we should fear.
In an erroneous way, on many occasions we use this type of malware for a multitude of malicious codes in a general way. However, we must be clear that a virus is a specific type, yes, the oldest malware. To give us an idea of what we are talking about, the main objective of this software element is to spread. It usually hides in a file and infects the system when it is opened. The key element here is that it then tries to spread to other files.
This format is very virus-like, since it spreads in the same way, but with a difference. And it is that the worms directly attack and infect the system with which they come into contact, that is, it is not necessary to execute that infected file to trigger the infection. Hence, it is not necessary for the user to have to interact with it.
Here we find one of the most widespread and dangerous types of malware at the moment. The main reason for this is that its main objective is to take complete control of the computer. Once it has infected us and blocked its use, sometimes encrypting our data, the malicious code ask for a ransom to get the key and that we can figure it all out. In other words, it blocks our files so that we cannot access them and asks us for a ransom, usually in Bitcoin or another alternative cryptocurrency.
If we take a look at the name of this particular format, it is not difficult to imagine what its main objective is. And it is that this is a malicious code that is basically responsible for spying on us and collecting data in the background. Later the information collected it is sent to the cyber criminal and then used for any malicious purpose. The idea is that we never realize their presence.
Another type of malicious code that we should fear are Trojans. As its name suggests, its operation is based on pretending to be a legitimate application or file. The usual thing is that it is a fake program that we download thinking that it is the authentic one but that when executed it will infect the computer. Unlike a virus, it will not try to spread itself. It then takes care of carrying out all sorts of malicious actions depending on its design.
