Reyptson is a ransomware virus that targets mainly Spanish speakers. After your files get encrypted, they will become inaccessible and get the .REYPTSON extension appended to them. AES with 128-bit ciphers is the encryption algorithm being used for locking the files. The Reyptson cryptovirus tampers with registry entries and leaves a ransom note in Spanish, with demands for paying the ransom of 200 euros. Keep on reading to see how you could try to potentially restore some of your files.

Reyptson Ransomware – Infection

Reyptson ransomware has an interesting way of infecting computers and spreading after that. The payload file that executes the malicious script for this ransomware, which in turn infects your computer system, requires a bit of social engineering to work. At first, you will open or receive the following message in your E-mail:

If you click on the “Ver o imprimir factura” button you will trigger a redirect which connects to the following address:

  • http://www.melvinmusicals[.]com/facefiles/factura.pdf.rar

That address could change with future versions and updates of the virus. From the URL address, a fake PDF file is downloaded on your system that requires you to open it. Here you can see a sample of that file, submitted to the VirusTotal service:

That factura.pdf.exe file is the actual payload for the ransomware. If you execute it, your computer device becomes infected with the Reyptson virus. While your files are being encrypted, and a lot of processes are launched to make copies of the initial malicious file and replicate the virus. Also, the virus will launch every time you start your system. Moreover, you will see the following window pop up on your screen multiple times:

That is the Adobe Acrobat Reader being started with a special script that is made to look like the Reader software is hogging resources while trying to open a file called “SpotifyWebHelper.pdf” which is “missing”. That is not true and only seems that way, while the virus is silently encrypting your files in the background. The reason for that is that if you restart your computer or stop the internet connection at the moment of encryption, you will cut off the encryption process, leaving some of your files intact. There are other ways to stop ransomware and you should read the tips for ransomware prevention thread in our forum to know more.

The Reyptson virus might spread its malicious files over social media sites and file-sharing networks. Be careful with what you download from the internet and make sure you first scan it with a security tool. Furthermore, the Reyptson ransomware will spread further, once it infects your machine, via the Simple Mail Transfer Protocol and Thunderbird as it sends the same message from where the infection starts to all your contacts it finds. Thus, it can spread all over the world, if people click on the button that downloads the payload file.

Reyptson Ransomware – Analysis

Reyptson ransomware is a cryptovirus. After your files get encrypted, a ransom message will show up written in Spanish. Judging by that message, it is easy to presume that the ransomware is targeted at Spanish speaking users, but it is not excluded to hit other ones over the World as well, especially with its payload being distributed to your contact list in both Thunderbird and Mail server.

Reyptson ransomware makes an entry in the Windows Registry, about five times to achieve persistence, and could launch or repress processes inside the Windows Operating System. Some entries are designed in a way that will start the virus or some of its parts automatically with each launch of the Windows OS, as seen right down below:

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run /v “Spotify Web Helper v1.0” /f /d “%APPDATA%\Spotify\SpotifyWebHelper\Spotify.vbs

The ransom note will appear when the encryption process finishes. The note is written in the Spanish language and provides details about what the ransom price is, along with other instructions about what it will take to recover your files. The note has a plain text variant as well as one which is graphical and shows in a window.

The ransom note message with instructions has a version that shows as a pop-up window on your screen after the encryption process is completed. You can preview it from the below screenshot:

That ransom note message states this:

The actual ransom note is inside a file called Como_Recuperar_Tus_Ficheros.txt and you can see it here:

Reyptson ransomware describes in those ransom note files with instructions that your files are encrypted and to get them restored you need to pay a ransom of 200 euros. However, if you do not meet the initial deadline of 72 hours or three days, the sum you would have to pay will be 500 euro. You are given the following Web address on the TOR network service:

  • https://37z2akkbd3vqphw5.onion.link

You can preview that URL page in the below snapshot:

There it says the following:

Basically, there is little to no new information compared to what we have covered in the article up to this point. The criminals have even created a support page on that site platform. Either way, you should NOT under any circumstances contact or pay these cybercriminals. Your files may not get restored, and nobody could give you a guarantee for that. Furthermore, giving money to these criminals will likely motivate them to create more ransomware or do other criminal acts.

Reyptson Ransomware – Encryption

For the time being there is little information about the file extensions which the Reyptson ransomware seeks to encrypt. The following list is definitely followed in the encryption process, and thus files with the following extensions are being encrypted:

→.doc, .dot, .wbk, .docx, .docm, .dotx, .dotm, .docb, .xls, .xlt, .xlm, .xlsx, .xlsm, .xltx, .xltm, .xlsb, .xla, .xlam, .xll, .xlw, .ppt, .pot, .pps, .pptx, .pptm, .potx, .potm, .ppam, .ppsx, .ppsm, .sldx, .sldm, .accdb, .db, .accde, .accdt, .accdr, .pdf, .ani, .anim, .apng, .art, .bmp, .bpg, .bsave, .cal, .cin, .cpc, .cpt, .dds, .dpx, .ecw, .exr, .fits, .flic, .flif, .fpx, .gif, .hdri, .hevc, .icer, .icns, .ico, .cur, .ics, .ilbm, .jbig, .jbig2, .jng, .2000, .jpeg-ls, .jpeg, .xr, .kra, .mng, .miff, .nrrd, .ora, .pam, .pbm, .pgm, .ppm, .pnm, .pcx, .pgf, .pictor, .png, .psd, .psb, .psp, .qtvr, .ras, .rbe, .jpeg-hdr, .logluv, .tiff, .sgi, .tga, .tiff, .tiff, .ufo, .ufp, .wbmp, .webp, .xbm, .xcf, .xpm, .xwd, .cpp, .h, .cs, .sln, .idb, .txt, .dat

Interestingly enough, files that have the .jpg extension could be left unencrypted and are not touched in any way.

All files that get encrypted by the Reyptson virus will receive the .REYPTSON extension appended to them, after the original file extension. File names are unchanged.

The encryption algorithm that is used is AES with 128-bit ciphers.

The Reyptson cryptovirus is has not been seen to delete the Shadow Volume Copies from the Windows operating system. That means that you might be able to recover your files from previous copies of Windows.
