.Nuclear Files Virus – Distribution

The .Nuclear files virus could spread its infection via various methods. One of these methods is seen as the main one for spreading it, which is with a payload file that executes the malicious script for the ransomware, which in turn infects your computer system. Such a payload file can be seen distributed around the Internet via different outlets. Malware researchers have uploaded a sample in the VirusTotal service, as it can be seen from the following screenshot:

The .Nuclear files virus could spread its payload file on social media sites and file-sharing networks. Freeware applications which are found on the Web could be presented as useful but at the same time could hide the malicious script for the cryptovirus. Avoid opening files straight away after you have downloaded them. That stands especially for ones that came from sources like suspicious e-mails or links. What you should rather do is to scan files before opening them with a security tool, while also checking their size and signatures for anything dubious. Also, you should read the ransomware prevention tips given in the forum section.

.Nuclear Files Virus – Details

The .Nuclear files virus takes its name from the .Nuclear extension that it appends to all files that it encrypts. Malware researchers have found out that the cryptovirus is a variant of the the .BTCWare File Virus without much debate.

The .Nuclear files virus could make entries in the Windows Registry to achieve persistence, launch and repress processes in Windows. Some entries are designed in a way that will start the virus automatically with each boot of the Windows Operating System, and one such entry is outlined down below:

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

The ransom note of the virus will be put inside your computer system after the encryption process is finished. The note is written in English, but that doesn’t mean that English-speaking users are the main target of the malware. Inside the note, you will view the payment instructions for allegedly recovering your files. The ransom note is inside a file called “HELP.hta”.

That file will open up the following ransom note:

That ransom note reads the following:

All your files have been encrypted!
All your files have been encrypted due to a security problem with your PC. lf you want to restore them, write us e-mail [email protected]
You have to pay for decryption in Bitcoins. The price depends on how fast you write to us. After payment we will send you the decryption tool that will decrypt all your files.

  • Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam.
  • Your ID: [redacted]

    The developers of the Nuclear ransomware are using an e-mail address as a way to contact them. Instructions which are presented in the ransom note of the .Nuclear files virus should not be followed. You should NOT under any circumstances write to the cybercriminals. Nobody could give you a guarantee that your files will get restored if you pay the ransom. However, you could try to get 3 of your files decrypted, in case you need to use them with a potential decryptor tool released in the near future.

    .Nuclear Files Virus – Encryption

    If the .Nuclear files virus ransomware proves to be a variant of BTCWare or indeed uses its code, there is a high probability for it to target and encrypt files with these extensions:

    →.1c, .3fr, .accdb, .ai, .arw, .bac, .bay, .bmp, .cdr, .cer, .cfg, .config, .cr2, .crt, .crw, .css, .csv, .db, .dbf, .dcr, .der, .dng, .doc, .docm, .docx, .dwg, .dxf, .dxg, .eps, .erf, .gif, .htm, .html, .indd, .iso, .jpe, .jpeg, .jpg, .kdc, .lnk, .mdb, .mdf, .mef, .mk, .mp3, .mp4, .mrw, .nef, .nrw, .odb, .ode, .odm, .odp, .ods, .odt, .orf, .p12, .p7b, .p7c, .pdd, .pdf, .pef, .pem, .pfx, .php, .png, .ppt, .pptm, .pptx, .psd, .pst, .ptx, .r3d, .rar, .raw, .rtf, .rw2, .rwl, .sql, .sr2, .srf, .srw, .tif, .wb2, .wma, .wpd, .wps, .x3f, .xlk, .xls, .xlsb, .xlsm, .xlsx, .zip

    All files that get encrypted will receive the .[[email protected]].nuclear extension appended to them. Malware researchers state that the algorithm being used for the encryption process is RSA. Also, it appears that newer variants of the ransomware now reboot your computer system automatically after the encryption process is complete.

    The .Nuclear files virus will delete the Shadow Volume Copies of the Windows Operating System. That will make the encryption process more viable since it will eliminate one way for a possible file recovery. Continue to read and see what ways you can try out to potentially recover some of your file data.
