The .stun files virus is a ransomware that is part of the Dharma family of malware.

.stun Files Virus – How Did I Get It and What Does It Do?

The .stun ransomware may enter your computer as a result of you opening its virus file. Such infection fles may be spread either via e-mail as an attachment or by being uploaded on a website, pretending to be a legitimate software download. They often mimick invoices, receipts, documents from a bank, reports, job-related documents, setups for programs, portable software, cracks, patches and many other file types. The goal is to trick you as a potential victim to download and run the files.

Once the .stun variant of Dharma ransomware infects your computer, it may immediately drop the virus files in different Windows directories and under different file names. The most targeted directories often turn out to be:

  • %AppData%
  • %Local%
  • %LocalLow%
  • %Temp%
  • %Roaming%

After the virus files of the .stun Dharma ransomware variant are already dropped, the virus may obtain administrator rights on the computer it has infected, only to begin encrypting files. The files that may be encrypted by this variant of Dharma ransomware could be of the following file types:

  • Videos.
  • Images.
  • Audio files.
  • Documents.
  • Archives.

Once Dharma .stun ransomware encrypts your files, they start to appear like the following:

After this variant of Dharma ransomware has finished with its encryption, the ransomware may show the convention ransom note used by it:

To eliminate any chances of you recovering your files via Windows backup and recovery services, Dharma .stun ransomware may execute the following Windows commands that may delete the shadow copies and disable and stop Windows recovery services:

→ sc stop VVS
sc stop wscsvc
sc stop WinDefend
sc stop wuauserv
sc stop BITS
sc stop ERSvc
sc stop WerSvc
cmd.exe /C bcdedit /set {default} recoveryenabled No
cmd.exe /C bcdedit /set {default} bootstatuspolicy ignoreallfailures
C:\Windows\System32\cmd.exe” /C vssadmin.exe Delete Shadows /All /Quiet

Remove Dharma Ransomware and Restore .stun Encrypted Files

Be advised that removing Dharma ransomware may take some skill and time. You can follow the removal steps 1 and 2 below and manually search for and remove the virus files of Dharma ransomware. However, with manual removal you risk damaging your files, because Dharma .stun ransomware may have mechanisms that trigger fail-safe scripts. This is why according to security experts, the best course of action towards removing Dharma ransomware is to skip step 1 and 2 and proceed to remove the virus automatically by downloading an advanced anti-malware program. This tool will not only save you a lot of time compared to manual removal, but it will also effectively and safely delete Dharma .stun ransomware from your computer plus protect it against future infections too.

When it comes to your files, be advised that at this point, files, encrypted with the .stun extension added cannot be decrypted for free. But this does not mean that paying the ransom will solve your problem – it is NOT recommended. Instead, we advise you to backup the .stun files on your computer and wait for a free decryptor to be released by malware analysts. When it has been, we will update this article with a download link. In the meantime, you can try to recover your files by the alternative methods we have posted underneath. They may not be with a 100% recovery success rate, but they might be able to help you get at least some of your files back.
