.0000 CryptoMix Ransomware – More Information

There is not much that differs the .0000 file ransowmare from the other CryptoMix variants it derives from. The malware drops it’s malicious files on the victim’s computer upon infecting it by either downloading them from a remote host or extracting them in an obfuscated manner. The malicious files that are dropped by the .0000 files virus may have different names and are usually located in the commonly targeted Windows folders:

After those files are dropped on the computer of the victim, the CryptoMix ransomware may perform various different activities, starting with:

  • Creating mutexes.
  • Touching system files and processes.
  • Modifying registry sub-keys in the Windows Registry Editor. Deleting the Shadow Volume copies and disabling System recovery.

Regarding the registry editor and the Windows registry sub-keys, the .0000 CryptoMix variant may attack the Run and RunOnce Windows Registry sub-keys. This may result in the ransomware’s encryption file running automatically on system boot. The registry keys which may be attacked by it, have the following locations:

→ HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

After having modified the registry editor, the .0000 ransomware may also delete the shadow volume copies of your computer by running the following commands as an administrator in your Windows Command prompt without this appearing visually on your screen:

→ bcdedit /set bootstatuspolicy ignoreallfailures
bcdedit /set recoveryenabled No
bcdedit /set {default} bootstatuspolicy ignoreallfailures
bcdedit /set {default} recoveryenabled No
vssadmin delete shadows /for= [/oldest | /all | /shadow=] [/quiet]

The virus also makes sure that it’s presence is known on your computer by adding the _HELP_INSTRUCTION.TXT ransom note, which has the following contents:

.0000 Files Virus Encryption Process

The encryption of the .0000 files ransomware is conducted in the same way as other CryptoMix variants. The virus begins by having a pre-configured set of file extensions which it scans for in order to encrypt them. These file extensions belong ot the most often used file types, like videos, archives, documents, images and others, for example:

PNG .PSD .PSPIMAGE .TGA .THM .TIF .TIFF .YUV .AI .EPS .PS .SVG .INDD .PCT .PDF .XLR .XLS .XLSX .ACCDB .DB .DBF .MDB .PDB .SQL .APK .APP .BAT .CGI .COM .EXE .GADGET .JAR .PIF .WSF .DEM .GAM .NES .ROM .SAV CAD Files .DWG .DXF GIS Files .GPX .KML .KMZ .ASP .ASPX .CER .CFM .CSR .CSS .HTM .HTML .JS .JSP .PHP .RSS .XHTML. DOC .DOCX .LOG .MSG .ODT .PAGES .RTF .TEX .TXT .WPD .WPS .CSV .DAT .GED .KEY .KEYCHAIN .PPS .PPT .PPTX ..INI .PRF Encoded Files .HQX .MIM .UUE .7Z .CBR .DEB .GZ .PKG .RAR .RPM .SITX .TAR.GZ .ZIP .ZIPX .BIN .CUE .DMG .ISO .MDF .TOAST .VCD SDF .TAR .TAX2014 .TAX2015 .VCF .XML Audio Files .AIF .IFF .M3U .M4A .MID .MP3 .MPA .WAV .WMA Video Files .3G2 .3GP .ASF .AVI .FLV .M4V .MOV .MP4 .MPG .RM .SRT .SWF .VOB .WMV 3D .3DM .3DS .MAX .OBJ R.BMP .DDS .GIF .JPG ..CRX .PLUGIN .FNT .FON .OTF .TTF .CAB .CPL .CUR .DESKTHEMEPACK .DLL .DMP .DRV .ICNS .ICO .LNK .SYS .CFG

After detecting the files, the malware uses the AES encryption algorithm in order to encrypt the files. This process replaces the data from the original files with data from the encrypted file types. After doing this, the .0000 ransomware generates a unique AES decryption key. This key is assymetric and just like the XZZX ransomware variant of CryptoMix, the .0000 ransomware uses 11 RSA-1024 encrption keys to encrypt the AES assymetric key, used for the encryption of your files. This gives the .0000 ransomware the ability to work as an offline virus without even communicating with the cyber-criminals allowing their command and control server to be exposed.

After the encryption process of this CryptoMix ransomware variant has completed, the malware adds the .0000 file extension to the encrypted files and then completely renames them, so that you won’t be able to recognize which file is the most important to you. The files begin appearing like shown in the image below:
