Surt Virus – How Does It Infect?

Such as the recently seen ransomware Nnqp virus, Hudf Virus and Vtua Virus, the Surt virus could end up on your computer using one of the two main strategies that are often encountered in relation to this family:

  • In case you downloaded some type of a file which upon executing has caused the infection.
  • If you have opened some type of an email attachment or clicked on a link that is shared on an email message sent to you that appears important.

Surt virus could appear as if it is a very important document of some sort if you encounter it in your inbox, such as:

  • Invoices.
  • Work-related files.
  • Receipts.
  • E-Tickets for events or flights.

Usually, such email attachments often have malicious macros in them and opening these on your computer may trigger the following infection process:

Furthermore, many victims of STOP Ransomware have complained in our comment sections on our blog and our YouTube channel that they have gotten infected by some files they have randomly download it from the web, like:

  • Key generator (or Keygen).
  • Fake installation files.
  • Software patches.
  • Self extracting archives or regular archives.
  • Cracked portable versions of apps.
  • Software or game cracks.

What Does This Ransomware Do?

The Surt virus is involved in many malicious activities, among which the main one is to encrypt your files. This virus aims make its presence known to its victims and this is why it uses the SURTR_README.txt ransom note, containing its extortion message:

Besides dropping this ransom note file on your computer, the virus may also leave the following kinds of files in your Windows system directories, like:

  • %AppData%
  • %Local%
  • %Temp%
  • %System%
  • %system32%
  • %Windows%
  • %SystemDrive%
  • %LocalLow%

These files are often from different kinds and have random names, making them hard to find manually.

.surt Files – What Are They?

The .surt files are the result of this ransomware encrypting your important data. They have their core file structure changed to the encryption algorithm used, which is most often AES cypher.

The way this malware encrypts your files is it skips the system directories of Windows so that you can still use your computer to pay the ransom and scans for often used files, usually of the following kinds:

  • Video file types (.mp4, .avi, etc.).
  • Audio file formats (.mp3, .wav, etc.).
  • Pictures (.jpg, .png, .etc).
  • Archives (.zip, .rar, etc).
  • Document file kinds (.docx, .pptx, etc.).
  • Other types of often used data.

After encrypting your data, the virus leaves your files with its own file extension, that makes them appear like the following:
