Dharma .vanss Ransomware – Distribution Methods

To be widespread and infect computers effectively, the ones who spread this variant of Dharma ransomware may use different devious tactics. One of them is to spread the virus via an infection file that is added as an extension on spammed e-mail messages. Such types of files usually pose to be legitimate documents, like an invoice, a receipt or a banking statement. The e-mails are often set up to imitate legitimate messages from big companies, like PayPal, eBay, Amazon, LinkedIn, DHL, FedEx and even banks, for example:

In addition to via e-mail, the malicious files may also be uploaded on hoax or compromised WordPress websites, in the form of different exectutables, like;

  • Game or program patches or cracks.
  • Key generators.
  • License activators.
  • Installers.
  • Portable versions of programs.

In addition to this, the files that have been dropped may also be self-extracting archives or JavaScript files that may be uploaded in downloading scripts that are embedded on malicious URLs. This means that you may have become infected with Dharma ransomware by opening a web link that leads to automatic download and install of the infection file.

Dharma .vanss Ransomware – Analysis

The main malicious file of Dharma’s .vanss variant has been reported in VirusTotal to have the following technical specifications:

→ MD5:e86893b92eca6e8dfbcfb9bbc08ee973
SHA-1:acaf1392ea344a074cd4dd47faa6a7e1530747f

Size:4.72 MB

Once dropped on the victimized machine, the Dharma .vanss virus begins to interact with the following system files in Windows:

→ KERNEL32.dll
USER32.dll
WTSAPI32.dll

The .vanss variant of Dharma uses those .dll Windows files to import the following functions:

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

The Dharma ransomware then may interact with the following Windows files in System32:

→ 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\WindowsShell.Manifest
C:\WINDOWS\system32\MSCTF.dll

In addition to this, Dharma ransomware also modifies multiple registry sub-keys in Windows:

→ \Registry\Machine\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\996E.exe
\Registry\MACHINE\System\CurrentControlSet\Control\SafeBoot\Option
\Registry\Machine\Software\Policies\Microsoft\Windows\Safer\CodeIdentifiers
\REGISTRY\MACHINE\SOFTWARE\Policies\Microsoft\Windows\Safer\CodeIdentifiers\TransparentEnabled
\REGISTRY\USER\S-1-5-21-1482476501-1645522239-1417001333-500\Software\Policies\Microsoft\Windows\Safer\CodeIdentifiers
\Registry\Machine\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\ole32.dll
\Registry\Machine\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\oleaut32.dll
\Registry\Machine\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\version.dll
\Registry\Machine\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\comctl32.dll
\Registry\Machine\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\SHELL32.dll

Among the activities of the .vanss Dharma ransomware is to also drop it’s ransom note, called Info.hta on the victim PC. The note looks like the following when opened:

Dharma .vanss Ransomware – Encryption Process

Similar to the previous versions of Dharma ransomware, this one does not cheat the tradition and adds various differnent functions that skip encrypting files in the key Windows directories, like:

  • %System%
  • %System32%
  • %Windows%
  • %ProgramData%
  • %AppData%

This is done with the main purpose of leaving Windows active so that the victim can use the PC to pay ransom, which we highly advise against doing.

Dharma ransomware may then scan for the files it aims to encrypt by looking for them, based on their file extensions. The most targeted files naturally are the most commonly used ones, for example:

  • Pictures.
  • Videos.
  • Audio files.
  • Archives.
  • Virtual Drives.
  • Backups.

The virus then may use the AES encryption algorithm to encrypt your files. It may create encrypted copies of the files and delete the original ones or directly attack the files themselves. After the .vanss version of Dharma ransomware is done with your files, the malware generates an asymmetric decryption key, which is also encrypted so that only the crooks can use it to recover your files. The file name is also modified and has it’s file icon stripped down from it. Files, encrypted by .vanss Dharma ransomware look like the following:
