  • %AppData%
  • %Local%
  • %LocalLow%
  • %Roaming%
  • %Temp%
  • %Windows%

Before this Russian ransomware could reach the data encryption stage, it needs to interfere with some basic settings that control the regular system performance. Among the affected components are likely to be the Windows registry sub-keys Run and RunOnce. The functionalities of the first one could be used by the ransomware for the automatic execution of malicious files on each system start. So if you want to prevent this crypto virus from loading whenever you start your device, you should find all malicious values added under the Run sub-key and remove them.

Soon after the ransomware completes all infection stages, it drops the text file Как все эту шалашкину контору расшифровать.txt and loads it on the screen. The purpose of this message written in Russian is to blackmail you into transferring hackers an amount of 50 Russian Rubles converted in Bitcoin as a ransom fee for corrupted files.

Here is the text of the original ransom message displayed by this ransomware:

Привет дорогой друг! Да, я скупой жадина но я должен это сказать… прости… но……. все твои файлы… ЗАШИфРоВаНЫ!1!!11!!11!1 :DDDDDDDDD Алгоритм RSA! 2048 бит! 4096 лень! Он на простых числах базируется он. Сейчас расскажу вам просто. Пишите на grafimatriux72224733@protonmail.com. Мы предоставляем: Бесплатную расшифровку, Платную расшифровку (и Договорную расшифровку)

Converted in English with the help of an online translator, the same message reads:

Hello my dear friend! Yes, I am a mean greedy but I have to say it … forgive … but ……. all your files … are encrypted! 1 !! 11 !! 11! 1: DDDDDDDDD The RSA algorithm! 2048 bits! 4096 too lazy!

.Защищено RSA-2048 Files Virus – Encryption Process

All initial system modifications are applied so that the .Защищено RSA-2048 files virus could reach the main infection stage which is data encryption. For the completion of this stage, the ransomware activates a built-in encryption module that utilizes sophisticated cipher algorithm. This algorithm is known to be the RSA-2018. It encodes parts of target files’ original code and leaves them out of order. So when the encryption is done all corrupted files remain inaccessible and marked with the specific extension .Защищено RSA-2048.

Unfortunately, all files that store sensitive information could be encrypted by this ransomware including:

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