If you have been wondering which kind of malware is the most dangerous one, then we have the answer to that question. So far, the most harmful cyber threats are considered to be the Ransomware-based ones. The program we are going to describe below falls exactly into that category of file-encrypting, ransom-requiring cyber monsters. More information about this particular Ransomware and the whole type is available below.

Ransomware: purpose, origin and effects

Ransomware is believed to have originated in Russia at the end of the last century. At first there were two basic types of ransom-requiring programs: file-encrypting, the subgroup Cerber 4.1.3 belongs to, which specialize in making some data inaccessible to the affected user; and screen-locking, the subtype that targets only your screen and locks it, demanding ransom for unlocking it and letting you use your entire system properly after that. At the present moment we can distinguish some other types of Ransomware as the mobile-locking one (making the display of your phone inaccessible by covering it with a whole-screen random-requiring notification); and the government agency exploited type (used for punishing cyber criminals and making them pay fines).

The most used Ransomware subtype – the file-encrypting one and how it functions

Let’s discuss the characteristic features of Cerber 4.1.3 as exemplary file-blocking Ransomware. This kind of programs functions in the following way:

  • First the virus needs to enter your system. That may happen in many ways, however, often an infection occurs with the help of a Trojan horse virus. The two malware versions are often included in spam emails and their attachments and once you open one, the Trojan detects a vulnerability in your PC and sneaks the Ransomware inside it through this weakness. Another possibility is to get Cerber 4.1.3 as a drive-by download. This might happen by simply loading contagious webpages and you will never notice the occurrence of the contamination. You might also end up infected if you click on a fake ad – it will redirect you to a contaminated website and the virus will automatically infect you. Of course, there may be other possible sources such as torrents and video-sharing web pages and the infection technique is the same: you are directly contaminated by that malware once exposed to it.
  • The second important component of the contamination process is the scanning that Cerber 4.1.3 typically performs. It checks all your disks and drives for the files that have most been in use. Then the virus compiles a list with all that data.
  • After this, the actual encryption process takes place. The malware starts making all the enlisted data inaccessible via using a very complicated double-component key. This key includes a private and a public part. The public part is usually made available to you right away. However, to decrypt the encoded files you also need the second component – the private key, which is the one you are required to pay for. After every single file from the list gets encoded, you get a screen ransom-demanding notification. Usually such alerts include all the details about making the requested payment and sometimes some more bothering threats about your encrypted files.

Then, is paying the requested ransom enough to get the issue solved?

Unfortunately, most of the time this is not the case. In fact, the hackers might just abandon you and leave your files encrypted forever after you send them your money. If we were you, we wouldn’t pay before we try all the possibilities available in such a disturbing situation. Some of them include consulting an expert in the field for assistance. Maybe some professionals have secret ways of dealing with such dangerous viruses and it is always better to pay them and save your PC as well as your files than to simply pay some hackers and hope for the best. However, even experts could find it very complicated to fight such serious cyber infections. Another possibility for dealing with such malware is to try to remove it and encrypt your data via following the instructions in any well-prepared detailed removal guide, like the one we have compiled for you below. Maybe it will help you, but you get no guarantees again. What else you can do is purchase some special program for dealing with Ransomware, but it may and may not be efficient depending on your particular case.

What truly works in all cases is not catching Cerber 4.1.3 in the first place

Prevention is always the most efficient solution when it comes to all cyber threats. Some more specific tips when it comes to Ransomware include simply avoiding the potential virus sources as well as always BACKING UP whatever important files you want to keep safe. The more general piece of advice includes purchasing a top-quality anti-malware tool and learning how to be picky when it comes to surfing the web and downloading anything from it.
