.trosak Files Virus – How Did I Get Infected and What Does It Do?

The so-called .trosak files virus is classified as a data locker ransomware. This is due to the fact that it plagues computer systems in order to reach target files and encode them with the help of two sophisticated cipher algorithms. According to security researchers, it belongs to the infamous STOP ransomware family.

The spread of the payload file that activates .trosak ransomware on computer systems could be realized with the help of several shady methods of distribution. The most probable one is malspam. For it, hackers launch massive spam email campaigns that attempt to trick users into downloading the payload on their devices. To make users more prone to interact with corrupted elements (usually file attachments and URL addresses) hackers spoof the name of the email sender and present it as a representative of any legitimate institution.

The moment you open the payload on your machine the ransomware attack begins. During the attack, .trosak files virus passes through several infection stages in an attempt to evade detection and reach the data encryption stage. Once it reaches it activates a built-in cipher module to encode target files. For the encryption it utilizes two strong cipher algorithms – AES and RSA. At the end of it, all of the following files could be locked and renamed with the extension .trosak

  • Audio files
  • Video files
  • Document files
  • Image files
  • Backup files
  • Banking credentials, etc
