In case you have been infected by Trojan.Ransomcrypt.R, you may have a problem opening your files. Trojan.Ransomcrypt.R is a trojan horse from the Trojan.Ransomcrypt family and it aims to make money in return of decryption keys of encrypted user data. The R. variant uses a strong encryption algorithm. Security engineers advise users not to comply with the ransom note left by Troja.Ransomcrypt.R. What is also highly recommended is to scan the computer with an advanced anti-malware tool preferably in Safe Mode that will detect and remove all of the objects associated and try and decrypt the files using other methods for which you can find more information after this article.

Trojan.Ransomcrypt.R – How Did I Get Infected?

The primary method for infection this trojan may use is to attach documents and malicious files altogether in an email message. Such messages may be either a part of massive spam or targeted mail specifically to deceive the user of the infected computer. Either way it is highly advisable to use special software with active shields against online infections and spam and an email client that has such filters embedded.

Trojan.Ransomcrypt.R In Detail

According to Symantec ,once Trojan.Ransomcrypt.R is activated on your computer, the troubles begin for you. This particular Trojan is observed to be inserted onto your computer by other malware, most likely a Trojan.downloader. As soon after it has been executed, this trojan creates these files in the %Temp% user folder:

→a.qq; VAULT.txt; VAULT.hta; revault.js

It also creates the following files in the User profile folder:

→CONFIRMATION.KEY
Application Data\VAULT.KEY
Application Data\VAULT.hta
Application Data\Desktop\VAULT.KEY
Desktop\vault.txt
Desktop\vault.hta

The trojan also creates registry objects to run some of the previously created files on system startup:

→HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run\”vlt notify” = “mshta %UserProfile%\Application Data\VAULT.hta”
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run\”tnotify” = “notepad %Temp%\VAULT.txt”
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run\”vltexec” = “wscript //B //Nologo %Temp%\revault.js”
Besides the startup registry entries, the ransomware also makes other registry entries:
HKEY_CLASSES_ROOT\Vaulted\Shell\Open\Command\”|default|” = “mshta.exe vbscript:Execute(“msgbox “” STORED IN VAULT:””&vbNewLine&”” %1″”&vbNewLine&vbNewLine&ChrW(10139)&”” Visit for key: http://restoredz4xpmuqr.onion””&vbNewLine&vbNewLine&”” [accessible only via Tor Browser: http://torproject.org]””,16,””VaultCrypt [Permission Error: No Key]””:close”)”
HKEY_CLASSES_ROOT\.vault\”|default|” = “Vaulted”

After it has set every setting the trojan then proceeds with the act of encryption:

→xls ;doc ;rtf ;pdf ;psd ;dwg ;cdr ;cd ;mdb ;1cd ;dbf ;sqlite ;jpg ;zip ;7z

The trojan then encrypts the files with the .vault extension. An encrypted file may look similar to this:

→C:\ImportantDocument.doc.vault

The user tries to open the files they see a message that the file has been encrypted. After encrypting the files, the trojan launches an executable file named enigma.exe in the %Temp% folder that has been downloaded from this http location:

→tj2es2lrxelpknfp.onion.city

The downloaded file is reported to steal information from the web browsers of the user and to send them to the location it has been downloaded from.
