Dharma Ransomware

.vanss Dharma ransomware is a file-encrypting virus designed to lock important files in a computer. It is also another one of the new variants of Dharma ransomware. As per its name, it uses the “.vanss” extension in marking the files it encrypts. The instant it infects a computer, it drops the following malicious payload in the system:

MD5:e86893b92eca6e8dfbcfb9bbc08ee973
SHA-1:acaf1392ea344a074cd4dd47faa6a7e1530747f
Type: Win32 EXE
Size:4.72 MB

After dropping its malicious payload in the system, .vanss Dharma ransomware will start to interact with the following system files in Windows:

  • KERNEL32.dll
  • USER32.dll
  • WTSAPI32.dll

The DLL files listed above are used by the crypto-malware to import the following functions in the infected system:

  • LocalFree
  • GetProcessAffinityMask
  • LocalAlloc
  • GetModuleHandleA
  • GetModuleFileNameW
  • VirtualQuery
  • FreeLibrary
  • ExitProcess
  • Sleep
  • SetThreadAffinityMask
  • SetProcessAffinityMask
  • GetProcAddress
  • LoadLibraryA
  • GetProcessWindowStation
  • GetUserObjectInformationW
  • WTSSendMessageW

The functions listed are used for the data gathering module as well as to repress and launch processes. Moreover, .vanss Dharma ransomware might also modify the following Windows files under the System32 folder:

  • C:\WINDOWS\system32\winime32.dll
  • C:\WINDOWS\system32\ws2_32.dll
  • C:\WINDOWS\system32\ws2help.dll
  • C:\WINDOWS\system32\psapi.dll
  • C:\WINDOWS\system32\imm32.dll
  • C:\WINDOWS\system32\lpk.dll
  • C:\WINDOWS\system32\usp10.dll
  • C:\WINDOWS\system32\comctl32.dll
  • C:\WINDOWS\system32\shell32.dll
  • C:\WINDOWS\WinSxS\x86_Microsoft.Windows.Common-Controls_6595b64144ccf1df_6.0.2600.5512_x-ww_35d4ce83\comctl32.dll
  • C:\WINDOWS\WindowsShell.Manifest
  • C:\WINDOWS\system32\MSCTF.dll
  • C:\WINDOWS\system32\MSCTFIME.IME

In addition, .vanss Dharma ransomware also makes changes in the Windows Registry to allow it to run on every system startup which makes it a persistent threat. After all the modifications done in the system, the Dharma variant uses the AES encryption algorithm in encrypting its targeted files. It then adds the .vanss suffix to each one of the compromised files indicating that the files are encrypted with the .vanss Dharma ransomware.

Following data encryption, it releases files such as FILES ENCRYPTED.txt and Info.hta both of which contains the ransom note that states:

“All your files have been encrypted!
All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the email [email protected]
Write this ID in the title of your message [removed]
In case of no answer in 24 hours write us to these emails: [email protected]
You have to pay for decryption in Bitcoins. The price depends on how fast you write to us. After payment, we will send you the decryption tool that will decrypt all your files.”
