Detailed Look at Kryptonite Ransomware Virus

Kryptonite virus is a data locker ransomware, and its primary goal is to modify the original code of sensitive files with the help of RSA encryption algorithm. Thus they become inaccessible by victims, and cyber criminals can extort a ransom payment from them. Remember that cyber criminals often act dishonestly in order to gain the demanded $500 without providing working decryption solution.

The infection process begins once Kryptonite payload is running on the system. Тhe malicious executable files cad.exe, snake-game.exe, and snake_game.exe are associated with Kryptonite ransomware attack so far. They are developed in a way to terminate processes, read particular data, use their functionalities and create new malicious files. All these specifics set in Kryptonite malicious code allow it to perform various activities rendering the system extremely vulnerable at the end of the infection.


Kryptonite virus is disguised as a game of Snake which starts when the malicious executable is opened. Even though the ransomware is believed to be in development the game is running good and can be played. What some users may miss while playing the fascinating game is the nasty Kryptonite infection that is also running and corrupts particular files in the background. All files touched by Kryptonite virus remain inaccessible by any software except the decryption tool as they are encrypted via strong cipher algorithm. Currently, a particular file extension associated with Kryptonite ransomware is missing so corrupted files may be recognized by their icon (usually white sheet in Windows). Their file type may be changed, and a double click on a corrupted file won’t result in file opening. Usually, Kryptonite and other similar data locker ransomware like PSCrypt, affect files that contain valuable information like images, photos, videos, music, documents, text files, archives, and all MS Office documents.

Of course, Kryptonite virus doesn’t remain hidden all the time. It is designed to replace the desktop wallpaper with an image called 1.jpeg and drop a ransom note file Ransom Note.txt on the Desktop. The 1.jpeg image depicts informative message about the infection and directs to the instructions included in Ransom Note.txt file. Here is the whole illustrated text:

All your files, images, vidoes and databases have been encrypted with an RSA-2048 private and unique key generated for this computer stored on a secret server.
