What is Mole66 ransomware?

Mole66 is the latest version of CryptoMix ransomware

Mole66 ransomware - the latest CryptoMix variant

Mole66 is a crypto-malware that belongs to the CryptoMix ransomware family. It has been revealed at the end of March 2018 by a group of ransomware researchers and caused commotion due to active CryptoMix rebound. The Mole66 Cryptomix ransomware targets the most popular files types and uses AES[1] cipher to lock them. Upon encryption, personal data gets .MOLE66 file extension and the victim is presented with the _HELP_INSTRUCTIONS_.TXT ransom note.

Name Mole66
Family CryptoMix
Danger level High. Locks files and demands a ransom
Decryptable No. Removes Volume Shadow Copies and Restore option. Practically impossible to unlock files
Symptoms File names appended with .MOLE66 file extension. _HELP_INSTRUCTIONS_.TXT ransom note on the desktop
Related files BC2D64A077.exe
Distribution spam attachments, malvertising, exploit kits, fake software updates
Removal options Automatic only. Download FortectIntego and run a full system scan

Likewise, CryptoMix and most of its versions, Mole66 ransomware's payload is distributed via malicious scripts embedded into online ads, spam email attachments, fake software updates, and exploit kits. The virus is usually disguised under BC2D64A077.exe file, which once executed roots into the % AppData% \ BC2D64A077.exe location.

Mole66 Cryptomix ransomware variant exhibits a high danger level. Yes, it locks files and demands the victim to pay the ransom in Bitcoins within 72 hours. However, it stops the Volume Shadow Copy (VSS) Service and runs the following scrips via an elevated Command Prompt:

  • C:\WINDOWS\system32\cmd.exe” /C sc stop VVS”
  • C:\WINDOWS\system32\cmd.exe” /C sc stop wscsvc
  • C:\WINDOWS\system32\cmd.exe” /C sc stop WinDefend
  • C:\WINDOWS\system32\cmd.exe” /C sc stop wuauserv
  • C:\WINDOWS\system32\cmd.exe” /C sc stop BITS
  • C:\WINDOWS\system32\cmd.exe” /C sc stop ERSvc
  • C:\WINDOWS\system32\cmd.exe” /C sc stop WerSvc
  • C:\WINDOWS\system32\cmd.exe” /C vssadmin.exe Delete Shadows /All /Quiet”
  • C:\WINDOWS\system32\cmd.exe” /C bcdedit /set {default} recoveryenabled No”
  • C:\WINDOWS\system32\cmd.exe” /C bcdedit /set {default} bootstatuspolicy ignoreallfailures”

Consequently, Volume Shadow Copies are removed permanently without leaving the victim the option to retrieve files encrypted by .MOLE66 file extension using ShadowExplorer or another third-party recovery tool. Besides, MOLE66 CryptoMix ransomware disables Windows Recovery and Repair options.

One the changes are made, MOLE66 virus generates a _HELP_INSTRUCTIONS_.TXT note on the desktop, which provides the following information:

Contents of the note on redemption:
!!! All your files are encrypted !!!
What to decipher write on mail
Do not move or delete files !!!!
—- Your ID: ***** —-
!!! You have three days otherwise you will lose all your data. !!!

The victim is demanded to contact crooks via email and indicate a unique ID to find out a redeem size, which is currently unknown. However, experts point out that it's yet another Bitcoin-related ransomware. The payment has to be transferred with 72 hours before permanent data removal.

The interesting fact is that the encryption is terminated if the ransomware scanner detects Russian locale. This fact implies a possible origin or close relation of the MOLE66 ransomware with Russia.[2]

The changes and data encryption that this ransomware initiates make data decryption practically impossible. Free decryptor has not been developed yet. Nevertheless, paying the ransom is not recommended due to the risk of both data and money loss. Even more, a supposed MOLE66 decryptor might be a rootkit that may download other malicious programs to your PC.

Mole66 CryptoMix ransomware exampleMole66 CryptoMix ransomware virus started its activity at the end of March 2018. It locks files and demands a ransom. Free file decryption is practically impossible

The only reasonable solution is to remove MOLE66 CryptoMix ransomware and recovery locked files from backups. If you don't backup your data, it might be problematic to get your files for free. Nevertheless, we would strongly recommend not to trust criminals and restrain from paying the ransom. Instead, run a scan with FortectIntego, SpyHunter 5Combo Cleaner or Malwarebytes to remove MOLE66 ransomware and then try third-party data recovery tools.

Possible ways to fall ransomware victim

Like CryptoMix and its family members, this particular ransomware exploits a multitude of social engineering strategies to attack people's PCs. Statistically, these are the most frequently used methods to spread the infection:

  • malicious spam email attachments;
  • malvertising;
  • fake software updates or downloads;
  • exploit kits.

According to[3] experts, there's no hundred percent protection from ransomware. Even the best anti-virus with updated definitions and real-time protection might fail to recognize zero-day and other attacks.

Thus, people must comply with safe online behavior rules. First of all, avoid visiting illegal and highly suspicious content. Gambling and porno sites are at the tops of the domains that are most frequently filled with malicious content. Besides, avoid installing updates and software when prompted by pop-up ads. Finally, don't forget to backup your files regularly.

Uninstall Mole66 Cryptomix ransomware for good

Manual Mole66 removal is not possible. The ransomware is a severe infection which alters some of the core system's functions. To get rid of it completely, you will have to use a professional anti-virus program, say FortectIntego. Besides, do not forget to update it before running a scan.

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
