.cmb Ransom Virus – What Does It Do

Being a variant of the CrySiS ransomware family, which exists in hundreds of variants, many of which are decryptable, Dharma .cmb ransomware has been reported to drop one or more executable files in the %AppData% Windows directory.

After doing so, the virus may modify the Windows registry entries, more specifically the Shell sub-key with the following location:

  • HKLM/Software/Microsoft/WindowsNT/CurrentVersion/Winlogon/Shell

Then, the .cmb virus may also modify the Run registry key to run the executable file(s) in the %AppData% directory. The key is with the following path:

  • HKLM/Software/Microsoft/Windows/CurrentVersion/Run/

This may result in the virus file booting alongside the Windows start-up process.

The Dharma ransomware also drops a ransom note file with a ransom message and places it somewhere easy to locate. Then, Dharma ransomware virus may attack files with the following file types to encrypt them:

Photo.png.id-{victimID}.[e-mail].cmb

After Dharma encrypts the files, the virus leaves the files no longer able to be opened and appends the file extension .id-{victimID}.[e-mail].cmb to each encrypted file.

After the encryption process of Dharma ransomware has completed, the virus may also delete the VSS (shadow copies) on the infected computer in order to prevent victims from restoring their files via these backups.

Recover files encrypted by the .cmb Files Virus Ransomware.

Method 1: Using Shadow Explorer. In case you have enabled File history on your Windows Machine one thing you can do is to use Shadow Explorer to get your files back. Unfortunately some ransomware viruses may delete those shadow volume copies with an administrative command to prevent you from doing just that.

Method 2: If you try to decrypt your files using third-party decryption tools. There are many antivirus providers who have decrypted multiple ransomware viruses the last couple of years and posted decryptors for them. Chances are if your ransomware virus uses the same encryption code used by a decryptable virus, you may get the files back. However, this is also not a guarantee, so you might want to try this method with copies of the original encrypted files, because if a third-party program tampers with their encrypted structure, they may be damaged permanently. Here are the vendors to look for:

  • Kaspersky.
  • Emsisoft.
  • TrendMicro.

Method 3: Using Data Recovery tools. This method is suggested by multiple experts in the field. It can be used to scan your hard drive’s sectors and hence scramble the encrypted files anew as if they were deleted. Most ransomware viruses usually delete a file and create an encrypted copy to prevent such programs for restoring the files, but not all are this sophisticated. So you may have a chance of restoring some of your files with this method. Here are several data recovery programs which you can try and restore at least some of your files:
