What Does Berost Ransomware Do?

Berost Virus ransomware utilizes a high standard for encryption. Its algorithm makes files unopenable and extremely hard to decrypt without the proper set of keys. Computers with the virus are sluggish during encryption, as the virus uses their CPU to help with the encrypting process. A ransom message is displayed after the process is done. Berost Virus virus is also called .Berost Virus file virus by victims. Part of the STOP virus family, it is considered highly dangerous and persistent. Locked files get .Berost Virus extension after their names. The Berost Virus variant places a ransom message with instructions for paying hackers to allegedly get files back to their original state.

Oftentimes, they pose as representatives of well-known businesses so that you are more prone to carelessly interact with the malicious content. Trait number two: link to corrupted web page being it in the form of button, in-text link or image. Trait number three: the most common one – file attachment that contains malicious code.

Unfortunately, it is likely that all common files that are listed below are among the targets of this nasty ransomware:

  • Audio files
  • Video files
  • Document files
  • Image files
  • Backup files
