If all your necessary files have the .ransom virus extension and you can’t access them by no program, your computer has been infected with a ransomware infection. The .ransom virus is a type of ransomware that utilizes an encipher algorithm to encrypt target file types and make them out of reach until the unique decryption key is used. Hackers who disseminate the threat aim to extort a ransom from the victims in exchange for the decryption key.

This article aims to inform how to identify all .ransom virus file traits and remove it completely from the computer. Even though at this point there is no freely available decryption tool, the step six of the removal guide provided at the end suggests alternative data recovery approaches that may be efficient for the .ransom files recovery.

What Does .Ransom Virus File Cause to the PC?

The infection is triggered by a malicious executable file that is designed to perform various system modifications and ensure stable persistence. One of the main .ransom virus features carries out a deep scan of all PC drives so the threat can locate all target files and enforce its built-in encryption module. Whenever the threat detects a file that is set to its target list, it utilizes a strong encipher algorithm, probably AES to transform the original code completely. Commonly used file types are likely to be set as encryption targets so .ransom virus file may corrupt files that has the following file extensions:

.jpeg, .jpg, .mp3, .mp4, .pdf, .php, .ppt, .pptx, .rar, .rtf, .sql, .tiff, .txt, 7z, .bmp, .doc, .docm, .docx, .html, .xls, .xlsx, .zip

All encrypted files cannot be accessed by any software until the unique decryption key is applied. The key is generated during the encryption process and then transferred to a remote server controlled by the crooks. Each file that has appended the malicious file extension .ransom is encrypted.

Another strain of the malicious file that handles .ransom virus infection is designed to drop a ransom note file that contains a text message from the hackers. The analyses of the .ransom virus samples acknowledge that the ransom note is translated into several languages. All confirmed variants of its name are:

  • README_TO_DECRYPT_FILES.txt
  • LEAME_PARA_DESCIFRAR_ARCHIVOS.txt
  • PROCHTI_MENYA_DLYA_RASSHIFROVKI_FAYLOV.txt
  • LEGGIMI_PER_DECIFRARE_I_FILES.txt
  • LESEN_SIE_MICH_UM_DATIEIEN_ZU_ENTSCHLUSSELN.txt
  • LISEZ_MOI_POUR_DECHIFFRER_LES_FICHIERS.txt

The English version of the ransom message reads the following:

WARNING Encrypted Files
!!! YOUR FILES HAVE BEEN ENCRYPTED WITH RANSOMWARE !!!
[ENG] – [RUS] – [GER] – [FRA] – [ESP] – [ITA] The Key to Decrypt Your Files Will Be DELETED in 7 Days
Send Me 0.3 Bitcoins (You Have Only 7 Days From Now)

– https://localbitcoins.com/
– https://www.bitpanda.com/
After Send Me an Email With Your ID: *******
[email protected]
I Will Send You the Key to Decrypt Your Files

The text makes it clear that the crooks demand a ransom of 0.3 BTC within a seven day period. It is not mentioned what would happen after the deadline, however, we recommend all of you who are victims of the ransomware to avoid any negotiations with cyber criminals as it may expose your privacy and cyber security at a serious risk.

Among the malicious .ransom activities are also likely to be modifications in the Windows Registry. For instance, the ransomware may create new values in the Run or RunOnce registry keys that will allow it to display the ransom message on the screen and auto-execute its malicious payloads whenever the Windows is booted up. The following registry keys may have new malicious values created by .ransom virus:

  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

Finally, it is believable that the crypto virus has the functionality to enter a command in the Command Prompt panel and dele all saved shadow volume copies. Thus eliminates one of the possible data recovery approaches. The syntax of the whole command is:

vssadmin.exe delete shadows /all /quiet

How Can the .Ransom Virus Plague the Computer?

The most common way of ransomware distribution is spam email campaigns that distribute the malware. The emails allow hackers to impersonate legitimate sources used by the users and easily convince their targets to interact with the content presented in the email. They may be disseminating the malicious .ransom payloads as email attachments that once opened on the PC automatically start the infection or compromised URLs that download the ransomware unnoticeably when clicked.
These malicious components may also be distributed via popular social networks like Twitter, Facebook, Reddit, WhatsApp, etc.
