What is Eman ransomware? And how does it carry out its attack?

Eman ransomware is a new crypto-malware that also happens to be the latest variant of Matrix ransomware. It follows NEWRAR ransomware which was released not too long ago. Nothing much has changed in this new variant except for the extension it uses to mark encrypted files which are now .eman as well as its ransom note.

Eman Ransomware

Once it carries out its attack, Eman ransomware will drop its malicious payload in the system (nwovkcyl.exe). Upon the execution of the payload file, Eman ransomware will connect the infected computer to a remote server controlled by the attackers. After establishing a connection, it makes modifications in the Windows Registry so that it can run on every system boot. It also downloads additional malicious files in the system folders. These files along with the data gathered about the system and the user are then used for stealth protection which allows the crypto-malware to execute its attack without any interruption from any security programs.

After the system modifications, Eman ransomware will start encrypting its targeted files using both AES and RSA ciphers. Following data encryption, it adds .eman suffix to each one of the encrypted files and releases its ransom note, #README_EMAN#.rtf, which contains a quite lengthy message stating:
