.MOLE03 File Virus – Remove It and Restore Files

This article will aid you to remove the .MOLE03 File Virus completely. Follow the ransomware removal instructions given at the end of this article.

MOLE03 is the latest variant of Mole ransomware and is named after the extension it places on encrypted files, namely the .MOLE03 extension. Malware researchers believe that the code of the virus is based on the CryptoMix ransomware. The distribution can happen via spam e-mails and malvertising chains prompting you to download and update things or with malicious domains loading its payload. Once that payload is triggered after downloading it from any location, your data will get encrypted and the virus will leave a ransom note with instructions. Read on to see how you might try to potentially restore some of your files.

.MOLE03 File Virus – Distribution

The .MOLE03 file virus can distribute its infection through different methods. For now, one of the main distribution methods is via spam e-mails. Such an e-mail will pretend to be regarding some sort of a shipping notification and in most cases that a package has failed to be delivered. If you open the attached fake Word file, it will show that you have to download a plugin or something similar. If you do download that file, your PC will become infected with the cryptovirus.

Malware researchers have detected .MOLE03 file virus to distribute its payload file with the help of a Google Chrome pop-up message. Here is how that pop-up looks like:

If you open the malicious domain spreading it and namely, “one-hour.fr” you will see a fake Google Font Installer. If you open that with the Internet Explorer browser, you will see a tech support scam loaded on your browser that looks like this:

Refrain from downloading and opening files from suspicious websites like the examples portrayed above. You should always scan your computer system with a security tool. You should read the ransomware prevention tips written in our forum.

.MOLE03 File Virus – Details

The .MOLE03 file virus is dubbed like that due to the fact that it encrypts files while appending the .MOLE03 extension to them. Malware researchers claim that the ransomware is a variant of the CryptoMix ransomware virus.

After you have downloaded the ransomware there will be some sort of an error message popping on your screen. The result is a UAC (User Account Control) window launching and asking you to give permission for the execution of a certain command.

Giving that permission will launch the ransomware with Administrative privileges, and your computer will be scanned so your files to get encrypted.

The following files will be created:

  • ntuser.dat.log1
  • ntuser.dat.log2
  • some other files with similar names

Also, note that some processes could be stopped like Windows Defender and other similar security mechanisms of the Windows OS.

The ransom note will appear after the encryption process is finished. The note is written in English. Inside, you will see instructions with the demands for payment and how you might recover your files. The ransom note is inside the above-mentioned file called “_HELP_INSTRUCTION.txt” as it was with previous variants of the ransomware as well. You can preview it down here:

That ransom note reads the following:


All of your files are encrypted with RSA_2048 and AES_128 ciphers.
More information about the RSA and AES can be found here:

Decrypting your files is only possible with
he private key and decrypts program, which is on our secret server.

Follow these steps:
1. Download and install Tor Browsers: https://www.torproject.org/download/download-easy.html
2. After a successful installation, run the browser and wait for initialization.
3. Type in the address bar:

4. Follow the instructions on the site.

Below you can see the payment page hosted on the TOR Network, as a reference:

That page states the following:



Price of software and your private key is 1.0 bitcoins. With this product you can decrypt all your files.

If you are willing to pay for a software product, then:

Dear user, leave your DECRYPT-ID and e-mail. We will contact you within 24 hours and give further instructions. !!! You do not need to leave different electronic addresses, or the same address many times.

The ransom note of the .MOLE03 file virus should not be followed. You shouldn’t under any circumstances pay 1 Bitcoin (or any other sum) nor contact the cybercriminals. Your files may not even be restored, and nobody could give you a guarantee for that. Furthermore, supporting criminals is not a good idea. The crooks may get motivated to do more criminal activities, like creating more ransomware viruses.

.MOLE03 File Virus – Encryption

.MOLE03 file virus has an interesting encryption process. The encryption algorithms which are used for the process are both RSA with 2048-bit ciphers and AES with 128-bit ciphers.

Every file that gets encrypted will receive the same extension appended to each one of them, and that is the .MOLE03 extension. For instance Job.doc will look like YG8FGS87S7G4R8SF76SD7F8SD8FCPK3L.MOLE03 after encryption is done. Below you can see all file extensions that the .MOLE03 ransomware probably seeks to encrypt, if the list is unchanged from its previous variants:

→.doc, .xls, .pub, .odt, .ods, .odp, .odm, .odc, .odb, .wps, .xlk, .ppt, .mdb, .accdb, .pst, .dwg, .dxf, .dxg, .wpd, .rtf, .wb2, .mdf, .dbf, .psd, .pdd, .eps, .ai, .indd, .cdr, .jpg, .dng, .3fr, .arw, .srf, .sr2, .bay, .crw, .cr2, .dcr, .kdc, .erf, .mef, .mrw, .nef, .nrw, .orf, .raf, .raw, .rwl, .rw2, .r3d, .ptx, .pef, .srw, .x3f, .der, .cer, .crt, .pem, .pfx, .p12, .p7b, .p7c

The .MOLE03 file virus cryptovirus will delete the Shadow Volume Copies from the Windows operating system with issuing the command:

→vssadmin.exe Delete Shadows /All /Quiet

That also makes the encryption process more viable since it eliminates one of the ways for decrypting your data. Read on through and see what kind of ways you might try out to potentially recover some of your data.
