The image of Reyptson virus

Reyptson virus operates as crypto-threat capable of encrypting netizens' data with the AES cipher. After the process, the malware appends .REYPTSON file extension to the data. Since the virus is written in the Spanish users, the malware targets users of this country. 

Furthermore, recent analysis has revealed the threat's tendency to hack victims' Thunderbird contact list and plague its contacts with fraudulent invoices messages. Now it clearly prefers Spanish netizen. They are expected to receive the biggest share of such emails. At the moment one of the counterfeited senders is Folcan S.L. Facturación.

Here is a short extract of the fake email[1]:

Si tras leer la información de facturación ha localizado algún error no dude en respondernos a este mismo correo con el numero de factura y el numero de pedido.

Impuestos aplicables incluidos.

The developers have devised the GUI which leads users to the following pages of the file recovery. In the Como_Recuperar_Tus_Ficheros.txt file, the perpetrators instruct victims to pay 200€ within 72 hours. If a victim fails to do that within the specified amount of time, the sum of the ransom increases up to 500 euros. Its origin is still not fully investigated, but its trojan, Trojan.Zusy.D3C2E4 or Ransom.FileCryptor, suggests that it is related to some previous crypto-malware, for instance, FileIce ransomware which occupied the system via the similar trojan.

The malware exploits several methods of distribution: RDP, trojans, and spam emails. What is more, the malware also targets a wide choice of file formats. Regarding never-seen before features, this threat surely seems to be the result of professional cyber criminals. Luckily, multiple security tools are able to detect the infection so that you can remove Reyptson. For instance, Reimage or Malwarebytes Anti Malware might be of assistance when eliminating the malware.

Europe is getting targeted more

While the US happens to be the country which is the most frequent source and destination of crypto-malware, more international threats are spicing things up in the market. Speaking of international threats, Spanish-oriented[2] threats are becoming a norm.

Previously, we have seen the romantic version of CryptoLocker Il tuo computer e stato infettato da Cryptolocker!, Reetner ransomware, etc.

In comparison with the recently emerged threats, Reyptson malware happens to be quite a complex threat. In the ransom message, the malware indicates the .onion website address: http://37z2akkbd3vqphw5.omon/7usuario…., though it connects to multiple websites.

The malware roots in the system quite much. It disperses its file in several Appdata locations. Reyptson threat also leaves its entry among the registry files, launches multiple processes. Thus, during the infection, you may spot that the computer starts underperforming[3]. Another significant feature is its distribution.

Ways to spread the infections and prevention tips

It is a common tendency among the hackers to disguise the files under the names of the application.
%APPDATA%\Spotify\SpotifyWebHelper\SpotifyWebHelper.pdf, HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run /v, Spotify Web Helper v1.0[4], SpotifyWebHelper.exe, SpotifyWebHelper.pdf, Spotify.vbs suggest that the infection mainly spreads via the corrupted version of Spotify. Netizens should beware of factura.pdf.exe as well.

It will be appended to the fake invoice. Once a victim opens the file, the malware connects to Command and Control server. It will then retrieve a unique ID specific to the victims' device. Additionally, the malware will also send the request for UJBTFity cookie, though its purpose remains unclear for now.

It is known that the malware also targets users via Remote Desktop Protocols. In that case, it is crucial to change the passwords and enforce the protection, but also fortify the overall security of the system. In order to do that, the anti-virus and anti-malware security applications are necessary. Now let us proceed to Reyptson removal options.
