Kristina Ransomware – Analysis
Kristina is a virus that encrypts your files and extorts you to pay a ransom to supposedly recover them. The virus is also known as “KristinaCS” or “Kristina Crypto System” and discovered to be a variant of the .Crypt12 File Ransomware.
Kristina ransomware might make entries in the Windows Registry to achieve persistence, and could launch or repress processes in a Windows environment. Such entries are typically designed in a way to launch the virus automatically with each start of the Windows Operating System.
A ransom message is displayed in a GUI window after the encryption of your files is complete. You can view that window screen (named KristinaCS L 1.2) from the following screenshot, right down below:
The window shows what files are encrypted.
The actual ransom note states the following:
Your files Have Been Crypted email to: email@example.com for instructions;
That note can also be seen as your new Desktop image as red text on a black background:
The note of the Kristina ransomware states that your files are encrypted. You are demanded contact an email address, on which you will be told what sum you have to pay as ransom for your data. However, you should NOT under any circumstances pay any ransom. Your files may not get recovered, and nobody could give you a guarantee for that. Moreover, giving money to cybercriminals will most likely motivate them to create more ransomware viruses or commit different criminal activities.

An example of a full name with the appended extension for a locked file would be “firstname.lastname@example.org”. The encryption algorithm used by the virus is currently unknown.
The targeted extensions of files which are sought to get encrypted are currently unknown and if a list is discovered, it will be posted here as the article gets updated. The files used most by users and which are probably encrypted are from the following categories:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
The Kristina cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:
→vssadmin.exe delete shadows /all /Quiet
In case the above-stated command is executed that will make the encryption process more efficient. That is due to the fact that the command eliminates one of the prominent ways to restore your data. If your computer device was infected with this ransomware and your files are locked, read on through to find out how you could potentially restore your files back to normal.
