Ransomware – Distribution Methods

The creators of virus do not mess about when it comes to spreading this virus and infecting computers. They have realized that this is the most important part if they are going to make a profit out of your important data and have heavily concealed from antivirus programs the files dropped on your computer via malicious executables. Such executables may be used as e-mail attachments in so-called phishing e-mails that aim to resemble a legitimate company or a person with convincing statements in them that get users to open such attachments.

Not only this, but the malicious executable may be an Exploit Kit or a .js (JavaScript) file that pretends to be a legitimate Adobe .PDF document or a Microsoft Office document or any other file that may fool the inexperienced user into downloading and opening it. Ransomware – In-Depth View

When users open the exploit kit, it may immediately connect to a remote domain and download the payload of the virus. Like other .XTBL ransomware viruses, it may create it’s malicious files in the following Windows folders:

  • %AppData%
  • %Roaming%
  • %Local%
  • %Temp%

However, the virus may also create copies of an .HTML and .hta files that contain it’s ransom note together with it’s malicious executable file that encrypts the files of the compromised computer. These files are reported by researchers to be dropped in the %Strartup% folders:

C:\Users\ {User’s profile}\ AppData\ Roaming\ Microsoft\Windows\ Start Menu\Programs\ Startup\ Decryption instructions.jpg
C:\Users\ {User’s profile}\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\ Startup\ Decryption instructions.txt
C:\Users\ {User’s profile}\ AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup\ {malicious payload file}.exe
C:\Windows\System32\ {malicious payload file}.exe

This is done to make these files run every time you turn on or restart your Windows computer.

Regarding file encryption, ransomware virus may attack the shadow copies and other backups and delete them using the vssadmin command, called delete shadows and executing it in administrative “quiet” mode so that the victim doesn’t suspect it.

After having begun to encode the files of users, ransomware is focused on scanning for and detecting to encrypt widely used types of files, for example:


After files that have been encrypted by ransomware have been scrambled, the virus appends a very specific file extension to them, which includes the e-mail address, a unique identification number, and the .xtbl file extension. Encrypted files by this malware look like the following:
