Eman ransomware – Matrix version that locks data using AES-128 and RSA-2048 algorithms

Eman ransomware is the newest variant of a well-known crypto-extortionist called Matrix. This file-locking virus has been affecting victims since 2016 and has mostly been known for its double encryption algorithm.[1] The particular version is also using AES and RSA encryption methods to encode files and marks them with .EMAN file extension. Once encrypted, data becomes useless, and there is no way to distinguish what is hiding in those files because they cannot be opened. The virus can easily affect your photos, videos, documents or even archives. However, ransomware viruses are focusing on gaining the money from their victims. To get a chance to ask it, the virus also drops a ransom note called #README_EMAN#.rtf which is set as the Desktop cover. There is no specific amount given in the ransom note, but, no matter how big or small, the required payment is, you shouldn't pay for the developers of Eman ransomware.

Eman ransomware virus is a cyber threat that people are not happy to get because it costs money to get your files recovered. Unfortunately, often cybercriminals disappear after the payment and ignore the victims. It is possible that a decryption tool doesn't exist and hackers even lie about the whole file recovery aspect. At the moment, there is no information about the Eman decryptor.

This is the reason you shouldn't pay the demanded ransom because it may lead to money or permanent data loss. The best solution for this ransomware infection is performing Eman ransomware removal and then attempting to restore your files with the help of appropriate tools or backups. 

As a typical crypto-demanding virus, Eman ransomware develops a ransom note and places that on victims' desktop and the system in the form of the #README_EMAN#.rtf file. This ransom note reads the following:
