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: https://restoredz4xpmuqr.onion””&vbNewLine&vbNewLine&”” [accessible only via Tor Browser: https://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.
