Hackers can use many methods to sneak in viruses and steal passwords or information. However, there are certain methods that are more common. In this article we are going to talk about the two types of files that are currently most used to introduce malware. This way you will be able to know how they could attack you and be prepared to avoid problems.
File types most used to sneak malware
According to the latest report from HP Wolf Security, over 44% of malware currently arrives via compressed files. Specifically, hackers use ZIP and RAR files to send viruses in order to bypass security measures. This is significant, since until now the most used file type to sneak malware were Word or Excel documents.
What reason could there be for it? One possibility is that Microsoft’s move to automatically disable VBA macros a few months ago has pushed cybercriminals to use other methods to deliver viruses and malware of all kinds. They have found an option in the compressed files, which was already something that was being used frequently.
In many cases, hackers put files inside those password-protected ZIP or RAR files. They tell the victim what the key is and in this way, when they unzip it, they end up downloading viruses into the system. Inside those files may be malicious Word or Excel documents.
As you can see, hackers are constantly updating themselves and looking for new techniques to attack in order to scam victims. Although security measures, such as having an antivirus, are also constantly improving, sometimes they use certain vulnerabilities to achieve their goal.
What to do to avoid attacks with these files
So, what should we do to avoid computer attacks with this type of file? Undoubtedly the most important thing is common sense. Cyber criminals are going to need you to download those files. They may be sent to you by email, for example. Avoid downloading any files that could be a security problem.
It is also convenient to have security programs. Having a good antivirus will help detect malicious software. There are many options available, both free and paid. However, you should always choose one that is guaranteed and works correctly. For example, Avast or Windows Defender itself are good options.
On the other hand, having everything updated will help to avoid many problems. Sometimes attackers will exploit a security flaw to sneak in RAR or ZIP files and drop viruses. If you have the operating system updated to the latest version, as well as any program you use, you will avoid vulnerabilities and improve security.
In short, as you can see, the files most used to attack today are RAR and ZIP. It is important that you always maintain common sense and do not make mistakes to avoid viruses. Also, having a good antivirus and everything updated will be essential to protect your computer from intruders.
