What does “ransomware” mean?
Nowadays, the internet is full of various threats. The one of them is ransomware viruses. In this article we would like to tell you about the ways hot to prevent ransomware attacks and describe the mechanism they use. Generally, they belong to already known family of viruses, such as STOP(DJVU) or Dharma. However, sometimes hackers create unique ransomwares whose encryption algorithms are unique too. In the most cases, ransomware viruses sneak into the system by the means of fake installers. They can be easily found nearly everywhere on the internet. Hackers even create fake websites to promote such installers. In this case, both installer and site, imitate the original ones. Sometimes hackers use Remote Access Terminals, such as ScreenConnect. The main source of such programs is various bundles, the terms of installation of which are not always clear. Moreover, hackers can send you a malicious email. They inject the code of the virus into a regular and harmless file and then send it by email. The function of the messages is to lure victims to open the file.

Some of the ransomwares also establishes connection with various IP addresses for various reasons. For example, hackers use it in order to set the unique encryption key. When the encryption process is done, the files get new extensions, which are unique for every virus. Some of them also contain ID numbers or contact emails. Then the virus usually drops the ransom note. They can be of various formats. Some of the viruses create simple “.txt” files, some of them shows pop-up messages, some of them even create an application, that can be used to decrypt the files. The main purpose of such notes is to make victims to purchase a decryption tool, but in the most cases, hackers don’t respond to the messages after being paid.
